He mea hoʻonaʻauao o ka Chinese Academy of Science, Professor Ouyang Minggao, ke Kulanui o Tsinghua, koʻu ʻāina. He waiwai noi koʻikoʻi ka palekana o ka pākaukau i ka lawe ʻana a me ka huakaʻi hou, ʻoi aku hoʻi i ka palekana o ka ikehu, ʻo ia hoʻi ka nānā honua. Ua hoʻokumu ka US Department of Energy (DOE) a me ka German Science Institute (BMBF) a me nā loea kaulana i ka honua i kahi seminar palekana pākaukau honua (IBSW), a hoʻomau ʻia ma 2015 ma ke Kulanui ʻo Munich ma Kelemānia, 2017 ma Sandia National Experiment ma United States.

ʻO ka lumi, ua mālama maikaʻi ʻia ka mua a me ka lua o nā seminar palekana pālolo honua (IBSW). Ma ʻOkakopa 7, 2019, ua mālama ʻia ka 3rd International Battery Safety Seminar ma Beijing. ʻO ka General Assembly i mālama ʻia e Tsinghua University Battery Safety Laboratory, ʻo ke kumumanaʻo o ka hālāwai "ʻoi aku ka palekana ma mua o ke kiʻekiʻe kiʻekiʻe-specific battery no nā kaʻa uila".

Ma ka hālāwai, ua hoʻopuka ka mea hoʻonaʻauao o ka Chinese Academy of Science, ʻo Professor Ouyang Minggao, ke Kulanui o Tsinghua, i ka ʻōlelo nui, i hoʻopuka i ka "Safety Research of Tsinghua University Motor Lithium Battery". Hoʻonohonoho ʻia ka ʻike, penei: e nā lede, nā keonimana, maikaʻi nā mea a pau! No ke Kulanui o Tsinghua au. ʻO ka mea mua, hoʻolauna mākou i kā mākou Tsinghua University&39;s new energy power system research group.

Mai ka makahiki 2001, ʻo mākou mai ka makahiki 2001 ka hui noiʻi kūikawā nui a me ka hui hoʻomohala o nā kaʻa ikehu hou o ka ʻāina, a ʻo ia hoʻi ka hui alakaʻi ma Kina a me ʻAmelika Hui Pū ʻIa. He mea koʻikoʻi kā mākou hui no kekahi mau noiʻi, ʻo ia hoʻi nā pākahi lithium mana, nā pākahi mana wahie a me ka mana hybrid. Ma keʻano o ka mana lithium battery, he mea nui mākou e hana i ka palekana; He mea nui mākou e hana i ka lōʻihi i nā ʻeke mana wahie; ma ke ʻano o ka hybrid, he mea nui mākou e hana i ka hoʻokuʻu ʻana i ka ʻenekini hoʻopau i loko.

No laila, ʻo kā mākou mau mea nui ʻekolu. I kēia lā ua hāʻawi wau iā ʻoe i kahi hoʻolauna koʻikoʻi i kā mākou hopena noiʻi i ka palekana. Loaʻa ʻia ʻo Tsinghua University Battery Safety Lab ma 2009.

ʻO ka manaʻo nui e hana i ka palekana pākaukau. ʻOiaʻiʻo, ʻaʻole ka mana o ka wela o ka pākaukau. Ma ʻaneʻi, hoʻolauna wau iā mākou i ka holomua noiʻi ma waho o ka mana wela.

Hoʻomaopopo nā kānaka a pau ʻo ka palekana ka pilikia o ka nānā ʻana i nā kaʻa uila, a aia nā kumu like ʻole e hoʻokau ai i nā pōʻino palekana. Ke hoʻokomo ʻia ka wela i waho o ka mana i loko o kahi pākaukau, e laha ka ʻōnaehana holoʻokoʻa a pau, a i ka hopena ua hoʻokumu ʻia ka pōʻino. ʻO kēia kekahi o kā mākou mau hoa pili i ka palekana pākaukau, me nā mea hana kaʻa koʻikoʻi o ka honua a me nā mea hana pākaukau koʻikoʻi, a me nā mea hana kaʻa koʻikoʻi a me nā mea hana pākaukau koʻikoʻi ma Kina, a ua laikini pū mākou i nā patent waiwai naʻauao, nā hui kūloko a me nā ʻāina ʻē, etc.

ʻO kēia kā mākou hale hana palekana pākaukau. I nehinei, nui ka poʻe i hele mai i kā mākou hale hana. Welina mai nā mea a pau e kipa a hoʻololi.

Aia kekahi ʻano o ka hoʻāʻo ʻana i loko o kā mākou hale hana palekana pākaukau, ʻo ia kahi hoʻokolohua ʻokoʻa ʻē aʻe me ka ARC i ka wela-ma waho o ka mana. ʻO mākou ka ʻāpana honua o nā hoʻokolohua ARC ma nā pā lithium mana nui. Ma hope o ka nui helu o ka hoʻokolohua haʻawina, ua hōʻuluʻulu mākou i ekolu mau ano o ka pākaukau thermal waho-o ka mana, pakiko-wela hoʻomaka wela T1, thermal waho o ka mana trigger T2, thermal waho-o-mana kiʻekiʻe wela wela T3, ua hana pū mākou i ka hailona o ka mana lithium pākahiko hoao, E like me keia kanawai.

ʻO ka T2 ka mea koʻikoʻi loa, he aha ka pane ʻana iā T1 ʻoi aku ka akaka, maʻamau ka hoʻomaka ʻana o ke kiʻi SEI, hilinaʻi ʻo T3 i ka enthalpy hopena holoʻokoʻa, ʻaʻole maopopo loa ʻo T2, akā ʻo ia ka mea koʻikoʻi loa, no ke aha ka piʻi lohi ʻana. No laila, ma o ka ʻimi ʻana o T2, ʻekolu kumu nui. ʻO ka mea mua, ʻoi aku ka maopopo, ʻo ia ke kaapuni pōkole i loko.

ʻO ka hope e pili ana i ka diaphragm, kahi pōkole pōkole. Aia kekahi mea hou illicited maikaʻi hoʻokuʻu oxygen, ka lithium lithium, hōʻuluʻulu i ka palena maikaʻi o ka oxygen, ka lithium maikaʻi ʻole, ka hāʻule ʻana o ka diaphragm, ʻo kēia mau kumu ʻekolu ke kumu nui o ka hoʻokumu ʻana o T2. Ma lalo iho ua hoʻolauna wau i nā ʻano hana ʻekolu i ʻōlelo ʻia ma mua i ka mīkini a me ka holomua o ka mana o ka mana o waho o ka wela, e komo pū me ka mua, ka pōkole kūloko a me ka pōkole pōkole o kā mākou mana, ʻo ia ka BMS.

ʻO ka lua, ʻo ka wela i waho o ka mana a me ka hoʻolālā wela o ka pākaukau i hana ʻia e ka palena maikaʻi. ʻO ke kolu, ʻo ka thermostat i hana ʻia e ka hopena ikaika o ka lithium lithium a me ka electrolyte a me kā mākou mana hoʻopiʻi. Inā hiki i nā ʻenehana ʻekolu, hiki i nā ʻenehana ʻekolu ke hoʻonā i ka pilikia ma waho o ka mana.

Loaʻa iā mākou ka hoʻopunipuni hope loa, ʻo ia ka hoʻopaʻa ʻana i ka laha wela, pono mākou e hoʻomaopopo i ke kānāwai o ka laha wela, ʻoiai ke kāohi nei i ka laha wela, a i ka hopena e pale i nā pōʻino palekana. E ʻae mai iaʻu e hoʻolauna iā ʻoe i kēia mau ʻano ʻehā: ʻO ka mua, pōkole pōkole a me BMS. ʻOi aku ka maopopo o nā kumu mechanical, e like me ka collision, mechanical, a me ka hopena o ka waimaka o ka diaphragm, a i ʻole ke kumu o ka uila, e hoʻopiʻi ana ma luna o ka uku, lālā kristal lithium, dendritic puncture, a i ʻole overheating, ʻoiaʻiʻo, e hoʻopau loa ʻia, overheating hiki ke alakaʻi i ka hāʻule ʻana o ka diaphragm, pili nā kumu a pau i ka pōkole pōkole, akā ʻaʻole like ka hana o ka hopena, akā ʻaʻole ia ka hopena o ka hopena. ka hāʻule ʻana o ka diaphragm a me ka heheʻe ʻana o ka diaphragm.

No laila ke hoʻohana nei mākou i ka calorimeter hoʻomehana a me DSC, ʻo ia ka wehewehe ʻana i kāna ʻano hana mai ka exotherm o nā mea, ʻo ia ka wela i waho o ka pākaukau holoʻokoʻa mai ka hoʻololi ʻana o ka wela o ka pā pākahi holoʻokoʻa, a hoʻokomo i ka wela ma waho o ka mana hoʻokolohua heel hoʻokolohua. Hiki iā mākou ke ʻike i ka hoʻoheheʻe ʻana o ka diaphragm hiki ke hana i nā kaʻa pōkole kūloko, e hoʻomaka ana i ka mahana, a e hoʻokumu ka diaphragm crashes i T2, alakaʻi pololei i ka wela ma waho o ka mana, ʻo ia ke kumu maʻamau. Hoʻohana pū mākou i nā ʻano mea kōkua ʻē aʻe, me nā ʻano loiloi waiwai like ʻole, a me ke ʻano o ke kaumaha wela a me ka spectrometry lehulehu e nānā i nā mea like ʻole.

ʻO kēia kā mākou ʻano loiloi kumu, hiki iā ʻoe ke kālailai i nā ʻano ʻokoʻa, nā ʻano hana like ʻole. ʻO kēia ka mea mua, a he ʻano hoʻi ia o ke ʻano o ka thermal out-of-control, ʻaʻohe mea, hiki iā mākou ke hana i nā hana he nui mai ke kihi hoʻolālā, ʻaʻole lahilahi, akā ua lawa ka ikaika, akā ʻo ka waena He pilikia maʻamau i ka pōkole pōkole, no laila pono mākou e pale i nā kaapuni pōkole kūloko, pono mākou e aʻo i ke kaapuni pōkole, ʻo nā hoʻokolohua pōkole pōkole he paʻakikī, ʻaʻohe mea maʻamau, no laila ke hana nei mākou i ka hoʻomanaʻo ʻana i ka pākaukau. i kahi mahana, e hoʻohui i ka hoʻomanaʻo me ka ʻoi loa, e hoʻāla i ka wela. Mai ka palapala a me kā mākou noiʻi ponoʻī, ʻehā ʻano o nā kaapuni pōkole koʻikoʻi i loko.

Hiki i kekahi mau pōkole pōkole ke alakaʻi koke i ka wela o waho o ka mana, akā ua ulu mālie kekahi mau pōkole pōkole, a ʻaʻole paha he pōʻino kekahi pōkole, akā ʻo kekahi mau pōkole pōkole He mea weliweli loa ia, a ʻo kekahi mau pōkole pōkole e lohi mau, a aia kekahi mau pōkole kūloko mai ka lohi a hiki i ka mutations, aia nā ʻano like ʻole. I kēia hopena, ua hana pū mākou i kahi loiloi simulation, ʻaʻole wau i kikoʻī ma aneʻi. I ka pōkole, ua ʻike hope mākou ʻo ka hoʻololi ʻana o nā pōkole pōkole i ke ʻano evolution ʻo ia ka hāʻule o ka volta, ʻo ke kaʻina hana mua he mea nui e hoʻokuʻu i ka volta.

E piʻi ana ka mahana ma ka ʻaoʻao ʻelua, a ʻo ka hopena ka wela ma waho o ka mana. No laila e pili ana i kēia lohi, pono mākou i kāna kaʻina hana mua, ʻo ia hoʻi, ʻo ka hāʻule ʻana o ka uila e ʻike iā ia e hoʻoponopono, e kiʻi iā ia, e pale aku i ka pōʻino hou aku, ʻo kēia kā mākou Algorithm ʻike pōkole pōkole kūloko, ʻo ia kahi algorithm no ka pūʻulu pā uila, me ka mea mua i kālai ʻia mai ke kūlike o ka volta, a ua hāʻule ka puʻuwai pākahi, e hōʻike ana he pōkole pōkole kūloko kēia. Akā inā ʻaʻole hiki iā ʻoe ke hōʻoia, e hoʻohui i ka mahana.

Inā ua hoʻololi ʻoe ma hope o ka hoʻololi ʻana, hoʻohui mākou i ka sensor gas combustible, no laila aia kahi ala e lohi a hoʻololi. No ka laʻana, ʻo ka ʻike like ʻana o ka puʻupuʻu puʻupuʻu pākahi, ʻaʻole wau e hoʻolauna i ka algorithm kikoʻī. Hiki iā ʻoe ke ʻike maopopo ke ʻike maopopo ʻia ka pākaukau e iho ana i ka voltage.

ʻOiaʻiʻo, pono mākou e hana i nā ʻano hana ʻenehana, a aia kahi algorithm maʻalahi ʻaʻole lawa. Pono nō hoʻi e hui pū me ka ʻike kūpono o nā papahana he nui e hoʻokolokolo ai, ʻo ia ka ʻikepili, no laila koho mākou e hui pū me ka hui. I ka pōkole, hiki iā mākou ke warw maikaʻi mai kēia wahi, e like me ka micro-short circuit, no ka wikiwiki o ka hoʻopiʻi ʻana, no ka mea, he deformation ka pākaukau i ka wā o ka hoʻopiʻi ʻana a me ka hoʻokuʻu ʻana, e loaʻa iā ia kahi kānana, kahi e hōʻemi koke ai ka micro-pōkole kaapuni, e like me nā kīʻaha koko kanaka ʻO ka plaque i loko, hikiwawe ka thrombosis he paʻi, inā mākou e hoʻohana i ka lohi a me ka wela, ua wela.

Pehea e hana ai? Pono mākou e hoʻohana i kēia mea ʻike kinoea, hiki ke hana ma kahi o 3 mau minuke ma mua e hana i ka ʻōlelo aʻoaʻo wela. I ka pōkole, hoʻomohala mākou i kahi ʻōnaehana hoʻokele pākaukau hou e pili ana i kēia mau algorithm. ʻO ka ʻāpana ʻelua ka mīkini ʻelua a mākou i ʻōlelo ai, pōkole wale nō? Loaʻa ka wela me ka ʻole o ke kaapuni pōkole kūloko? ʻO ka ʻoiaʻiʻo, ʻaʻohe wahi kaapuni pōkole i loko e loaʻa ai ka wela i waho o ka mana.

Ke hoʻonui mau nei ka diaphragm, ke piʻi mau nei ka maʻi nickel o ka electrode maikaʻi ʻekolu mau lālā, ke emi mau nei ka mahana hoʻokuʻu, ʻo ia hoʻi, ʻoi aku ka maikaʻi o ka thermal stability o ka mea electrode maikaʻi, akā e lilo kā mākou diaphragm i ʻoi aku ka maikaʻi a me ka maikaʻi, no laila nāwaliwali. ʻO kēia ka hoʻokolohua a mākou i hana ai, ʻaʻohe pōkole pōkole, ʻaʻohe wela o ka mana, wehe mākou i ka electrolyte, aia ka wela i waho o ka mana, a hiki iā ʻoe ke ʻike mai ka waena, aia kahi spike wela ʻole, maikaʻi a maikaʻi ʻole kēia i ka ʻāpana hoʻokahi, hoʻopiha piha Ua kau ʻia ka pauka maikaʻi a maikaʻi ʻole i kahi ʻāpana, aia kahi kiʻekiʻe hoʻokuʻu nui, ʻo ia ke kumu i hoʻomaka ai. ʻOiaʻiʻo, aia ma hea ka piko wela? Hoʻololi i ka pae waiwai electrode maikaʻi, oxygen manuahi.

E nānā i ka piko o ka Holland, i ka wā e hui pū ʻia ai ka maikaʻi a me ka maikaʻi ʻole, ua hoʻoneʻe ʻia ka electrode maikaʻi ʻole. Inā ʻaʻohe peak, ua pani ʻia, hōʻike i ka wela i hana ʻia mai ka heterogenesis maikaʻi a me ka hopena electrode maikaʻi ʻole. No laila he aha kēia ʻano hana? ʻO ia ka hoʻololi waiwai o ka electrode maikaʻi a me ka maikaʻi ʻole, ʻo ia ka hopena maikaʻi o ka oxygen i ka electrode maikaʻi ʻole e hana i kahi hopena koʻikoʻi, kahi i hoʻokuʻu ʻia ai ka wela.

E pili ana i ka thermal out-of-control o ke kaapuni pōkole kūloko, hiki iā mākou ke hoʻokumu i kahi kumu hoʻohālike e like me nā hopena ʻaoʻao āpau wale nō nā hopena ʻaoʻao āpau. Ma o ka multi-rate scanning o DSC, hiki ke helu ʻia ka hopena mau o nā ʻaoʻao ʻaoʻao a pau i kēia ʻano, ʻoiaʻiʻo, ma o kekahi ʻano, i hui pū ʻia me ka mālama ʻana i ka ikehu, hiki i ka mālama ʻana ke helu i ke kaʻina piha o ka thermal out-of-control, a hiki ke hoʻokō maikaʻi ʻia me ka hoʻokolohua. Ma kēia ala, hiki iā mākou ke hoʻomohala mai ka ʻike pili e hoʻomohala i ka hoʻolālā kumu hoʻohālike, ʻoiaʻiʻo, he nui nā waihona, ʻaʻohe ʻikepili ʻaʻole, ʻo ia ka hopena o ka hopena o nā mea like ʻole a me ka pilina o ka wela.

Ma muli o ka waihona, pono mākou e hoʻomaikaʻi i nā mea, nā hoʻomaikaʻi koʻikoʻi aʻu i manaʻo ai ʻelua, ʻo ka hoʻomaikaʻi ʻana o ka mea maikaʻi, ʻo ka electrolyte kekahi. ʻO ka mea mua, hiki iā mākou ke hoʻonui i ka mahana o ka oxygen mai ka polysantial i ka kristal hoʻokahi, a hiki ke ʻike ʻia ua loli nā ʻano o ka thermal out-of-control. No ka laʻana, hoʻohana mākou i nā electrolytes kiʻekiʻe, he ala nō hoʻi.

ʻOiaʻiʻo, hiki i nā mea a pau ke ʻimi i nā electrolytes paʻa. He paʻakikī loa nā electrolytes paʻa. Manaʻo mākou he hiʻohiʻona maikaʻi ka concentrate ponoʻī.

No ka laʻana, ua hāʻule kona kaumaha wela, a ua hāʻule ka mana exothermic. Mai kēia waena hiki iā mākou ke ʻike iā ia, a ʻaʻole i hoʻopili ʻia ka maikaʻi me ka electrolyte, no ka mea, ʻo ka maikaʻi electrolysis hou ʻo DMC, DMC ʻo 100 degere Ua evaporated. ʻO kēia ka mea a mākou i manaʻoʻiʻo ai ʻoi aku ka nui o ka electrolyte ma mua o nā electrolytes paʻa, ʻoi aku ka nui mai ka additive o ka electrolyte, electrolyte kiʻekiʻe kiʻekiʻe, a hiki i nā electrolytes hou.

Mahele III, e pili ana i ka lithium lithium a me ka mana hoʻouka. Hoʻomaopopo nā kānaka a pau e haʻi wau i ka pā lithium-ion. Ma hope o ka hoʻemi ʻia ʻana o ka pākaukau, he aha ka palekana o ke ola holoʻokoʻa? Uaʻike mākou i nā mea nui loa i ka waena o ka palekana holoʻokoʻa holoʻokoʻa e nānā i ka lithium, inā ʻaʻohe kūlana o ka palekana o ka pākaukau lithium-emi ʻaʻole e deteriorate, ʻo ke kumu wale nō o ka deteriorating ʻo ia ke kālailai lithium.

Hiki iā mākou ke ʻike i nā hōʻike hōʻike, e like me ka haʻahaʻa haʻahaʻa haʻahaʻa wikiwiki, haʻahaʻa haʻahaʻa haʻahaʻa wikiwiki, ka mahana o T2 e emi mālie, a ʻo ka nalowale o ka wela ma mua, ʻo ia ka attenuation hiki i ka pākaukau, mai 100% a 80%. ʻIke pololei, lithically mai ka haʻahaʻa haʻahaʻa e hoʻopiʻi ana mai ka pākaukau hou i ka pākaukau kahiko. ʻO ka mea ʻē aʻe he wikiwiki wikiwiki.

Ma hope o ka hoʻouka wikiwiki, hiki ke ʻike ʻia ka hāʻule ʻana o ka mahana ma T2 i 100 degere. Mai ka hoʻomaka ʻana o ka pākaukau hou 200 a ʻoi aku ma mua o 100 degere, ʻoi aku ka wikiwiki o ka wela. He aha kēia kumu? He lithium lithium hoʻi, hiki iā mākou ke ʻike he nui nā lithium, a he liʻiliʻi ka liʻiliʻi o ka lithium.

ʻO ka loiloi o ka lithium he nui ka nui o ka exotherm, no laila he lithium nō ia, e hoʻopili pololei ka ua lithium me ka electrolyte, e hoʻonui ai i ka piʻi ʻana o ka wela, hiki ke hoʻoulu i ka wela. No laila, pono mākou e aʻo i ka lithium, e like me ka pōkole pōkole i kā mākou aʻo ʻana, pehea e aʻo ai i nā haʻawina lithium? ʻO ka mua hiki iā mākou keʻike i ke kaʻina hana o ka lithium lithium. Ke hoʻouka nei kēia, ua pau ka hoʻoukaʻana, hiki keʻikeʻia ua hoʻomaka ka lithium e hoʻomaka, aia kahi hapa nui o ke kua,ʻo kēia ka hana o ka lithium.

Hiki ke ʻike ʻia ka hoʻokolohua i kēia manawa mai ka Red Line, ʻo ia ka lithium i hoʻāla ʻia, lithium reversible. Aia kekahi hapa o ka make, reversible lithium, hiki ke hoʻopili hou ʻia, a ʻoi aku ka maikaʻi o ka electrode maikaʻi ʻole, a piʻi ka pae kiʻekiʻe o ka uila i ka 0, hiki ke hoʻohuli ʻia i ka lithium. ʻOiaʻiʻo, ʻaʻole hiki ke kiʻi ʻia ka lithium make.

Hāʻawi kēia iā mākou i ka wikiwiki. Hiki iā mākou ke hele i ke kaʻina hana o ka lithium reversible e ʻike i ka nui o ka lithium, no ka laʻana, ke hoʻi nei ia i kēia kaʻina hana, pili kēia kaʻina i kahi paepae ma kahi uila, ua hoʻohālikelike mākou, a loaʻa kēia kahua. Ke haʻahaʻa loa mākou, ʻaʻohe hanana, ʻo ia ka voltage maʻamau e polarize, ʻaʻole kēia kahua.

No laila, he hōʻailona maikaʻi kēia paepae,ʻo ka hopena o ka papahana hiki iā mākou ke hoʻoholo ma kaʻokoʻa,ʻo kēia ka hopena o ka paepae, e hōʻike ana i ka nui lithium, a aia kahi pilina me ka nui o ka lithium, hiki ke wānana i keʻano.

Ua hoʻomaka wale ka pūʻolo pila me nā pā ahi, nui loa ka uahi, lohi, ʻaʻohe ʻā, ʻaʻohe laha wela, ʻo nā ʻeke pākahiko maʻamau e hana i ka laha wela a me ka puhi ʻana.

Hiki iā mākou ke hala i kēia, ʻike maoli. ʻO kēia e pili ana i kēia hana, ke komo pū nei mākou i ke ʻano o nā lula honua. I kēia manawa ua hana hou mākou i kēia kaʻina hana he pele, ʻoi aku ka paʻakikī, i kēia manawa ʻaʻole mākou i hoʻohui i ka simulation, ʻoiaʻiʻo ke kumu hoʻohālike, akā ʻaʻole pololei.

Hiki ke ʻike ʻia mai ka hoʻokolohua ʻana aia ke kūlana paʻa, ka wai, ke kinoea tri-state, ʻo kēia kinoea waena kekahi mau kinoea combustible, ʻo ia ka wahie, ʻo ke aupuni paʻa kekahi mau ʻāpana paʻa, hana pinepine i ke ahi. Pehea e hana ai? ʻO kekahi o ka hōʻiliʻili ʻana i nā mea ʻala, e like me ke kaʻa kuʻuna, e hopu i ka mea ʻala ma o ka kānana. Ua hoʻoheheʻe ʻia ka mea ʻē aʻe, e hoʻokuʻu ʻia ke kinoea hoʻopau ma waho o ke ahi, ʻo ia kā mākou e hana nei i kēia manawa.

ʻO ka hope, e hana wau i kahi hōʻuluʻulu. ʻEkolu mau kaʻina hana o ka thermal out-of control, kahi i hana ʻia ai. I loko o ka induction, aia nā kumu like ʻole i ka hoʻokomo ʻana, ua ʻōlelo nui wau, ʻoiaʻiʻo, aia kekahi ʻāpana o kā mākou mīkini hui ʻana, ʻaʻole wau i ʻōlelo, aia mākou i mua o kēia mau mea, aia nō kēia mau mea ʻAʻohe hoʻoponopono i hoʻoponopono ʻia, manaʻo mākou ma hope.

ʻO ka lua, ʻaʻohe mana o ka wela. Ua ʻōlelo mākou i ʻekolu mau mahana, ʻekolu mau kumu i hōʻike ʻia ma aneʻi. Aia ka pele a me ke ahi i loko o ka pila.

He mea nui e hoʻoholo i ke kūlana o ka electrolyte, ka paila paila o ka electrolyte. ʻO ka hope loa, ua laha, a hiki iā mākou ke hoʻolaha, aia ka laha koke, e like me ke ahi, e ʻā ana i ke ahi hikiwawe, a hope loa i ke ahi nui, ʻo nā pilikia a pau a mākou i hōʻike ai ma ʻaneʻi e hoʻoponopono ai. .
