著者：Iflowpower – Dodavatel přenosných elektráren

Iphakethe lebhethri le-Lithium iron phosphate ion lisetshenziswa kakhulu, ibhethri elisetshenziswa kakhulu. Ibhethri ye-lithium-ion ibhethri eliphinde lishajwe, okubalulekile ukuthembela ekushumekeni kohambo olubuya nokubuya kanye nokuhlukaniswa kwe-lithium ion phakathi kwe-electrode ephozithivu kanye ne-electrode eyinegethivu, futhi kuzuzwe ukugcinwa nokukhululwa kwamandla. Uma ibhethri lishajwa, amandla kagesi angaphandle asetshenziselwa ukukhiqiza kabusha into esebenzayo yangaphakathi, futhi amandla kagesi agcinwa njengamandla amakhemikhali.

Lapho ekhishwa, amandla amakhemikhali aguqulwa abe amandla kagesi. Izigubhu zebhethri ze-lithium iron phosphate ion Imbangela: Yi. Isikhwama sesigubhu sebhethri se-lithium-ion ukushaja ngokweqile kubangela ukuba wonke ama-athomu e-lithium asendaweni ye-electrode ephozithivu agijimele kumpahla ye-electrode engalungile, okubangela ukuba igridi epholistiwe e-polarized iwe, lokhu futhi kuyi-iron phosphate Isizathu esibalulekile sokuncipha kwephakethe lebhethri le-lithium-ion.

Kule nqubo, ama-ion e-lithium we-electrode engalungile ayanda, futhi ukunqwabelana ngokweqile kwenza ama-athomu e-lithium abe made ngaphandle kwekristalu yesiphunzi, ukuze iphakethe lebhethri le-lithium ion liqhume. Okwesibili. Isikhwama sesigubhu sokuhumusha sikunqubo yokuqala yokushaja nokukhipha yebhethri ye-ion ye-lithium ewuketshezi, futhi okokusebenza kwe-electrode kusabela kusixhumi esibonakalayo sesigaba esiqinile-soketshezi ukwenza isendlalelo se-passivation esimboza ingaphezulu lempahla ye-electrode.

Ifilimu ye-passivation layer eyakhiwe ingavimbela ngokuphumelelayo ukudlula kwe-molecule ye-electrolyte, kodwa i-Li + ingashumeka ngokukhululekile futhi ikhishwe ngongqimba lwe-passivation, futhi inezici ze-electrolyte eqinile, ngakho-ke lolu ngqimba lwefilimu ye-passivation lubizwa ngokuthi i-SI. Ifilimu ye-SEI ayihlali njalo, kuzoba noshintsho oluncane ngesikhathi sokushaja nokukhipha inqubo, kubalulekile ukuthi ezinye izinto eziphilayo zizoshintsha izinguquko. Ngemuva kokukhishwa ngokweqile kwephakethe lebhethri le-lithium phosphate ion, i-membrane ye-SEI ibangela izindandatho ezihlehlayo eziphukayo, futhi ivikele izinto ezinamathelayo ezintweni ezingezinhle ze-electrode, ngaleyo ndlela yakhe into eningi.

Ezintathu. Isikhwama sesigubhu sebhethri se-lithium-ion singase sibe yinkinga yezinga lokukhiqiza lebhethri ye-lithium ion ion, ukumbozwa kwe-electrode akulingani, futhi inqubo yokukhiqiza inzima kakhulu. IV.

Isimo sebhethri ye-lithium iron phosphate ion battery pack akudingekile ukuba senzeke, njengoba umoya uqhutshwa ngogesi, ngakho-ke, isikhathi side kakhulu, esilingana nokuxhumana okuqondile ne-electrode enhle nengalungile yebhethri, kanye ne-Cronic Short circuit. Ukuxazulula kanjani ukucutshungulwa? Zama ukunganciki kwezinye izindlela zokufundisa ku-inthanethi, qhubeka nokusebenzisa ibhethri.

2, ngokuvamile, ungadlali omakhalekhukhwini, ukushaja. Hlala unamathela esimweni sebhethri ukugwema izimo eziyingozi. 3, imvamisa, lapho ushaja, naka ukukhetha kweshaja, isibonelo, i-voltage yokushaja elinganiselwe yebhethri ngu-3.

I-7V, umkhawulo we-voltage engu-4.2V, zama ukweqa le voltage, ingagcina imisinga eqhubekayo ihamba phambili. 4.

Khetha iphakethe lebhethri le-lithium iron phosphate ion elikhiqizwa umenzi, elithembeke kakhulu ngokwekhwalithi. Okubalulekile, noma ngokuvamile, imikhuba yakho yokusebenzisa, izinga lokulimala kwebhethri, kufanele unake kakhulu. 5.

Uma ibhethri likamakhalekhukhwini lishajiwe, wukuthola ukungabikhona kwebhethri ngeminwe yakho. Umoya uyaphela. 6, uma unamaphakethe ebhethri e-lithium phosphate ion amaningi asheshayo, kufanele kube i-cutoff voltage yeshaja oyisebenzisayo futhi nebhethri ayifani, ukushintshwa okunconyiwe.

Izizathu zezigubhu zebhethri: 1. Ukucindezela kwe-valve yokuphepha phezu kwebhethri ye-lead-acid elawulwa yi-valve ephezulu inikezwa umugqa wamavalvu okuphepha ukuze kuqinisekiswe ukusetshenziswa okuphephile, lapho ukucindezela kwebhethri kuphakama, i-valve yokuphepha izovuleka ngokuzenzakalelayo, yenze ingcindezi, Ukuqinisekisa ukuthi ibhalansi yokucindezela komoya yangaphakathi nangaphandle ebhethrini. Uma umfutho ukhuphuka ebhethrini, ivalvu yokuphepha ayikwazi ukuvuleka ngokujwayelekile.

Isikhathi eside, njengoba ingcindezi ebhethri iphezulu kakhulu, ingcindezi yegesi yangaphakathi nangaphandle ayilingani, kuyoba khona into eyenzeka ngezigubhu. Okwesibili. Onjiniyela bebhethri abagcwele ngokweqile bagcizelele ngokuphindaphindiwe ukuthi ibhethri kufanele ivimbele ukushajwa ngokweqile kanye nokuphuma ngokweqile, futhi ukushajwa ngokweqile kuzoholela ekuhlanganiseni kabi kwegesi ebhethrini.

Kukhona ukusabela okunzima kwebhethri ebhethri, enenani elikhulu lokushisa, okuholela kuma-electrolyte. Ukubola kwe-gasification, ibhethri liyaqhuma. III.

Umsinga wokushaja mkhulu kakhulu. Ngokwemiyalelo yebhethri, ibhethri ye-BT-HSE12V yamanje yokushaja ayikwazi ukudlula u-0.25C, futhi izincomo ezinconyiwe ngu-0.

1c (10a), kuyilapho ukushaja kwamanje kukhulu kunaleli nani lamanje elinengqondo, kulula Ukuhola imvula yepuleti le-electrode ngokushesha kakhulu, okuholela ekuphenduleni kwamakhemikhali okunganele. Ngalesi sikhathi, izinga lokushisa ngaphakathi kwebhethri lizokhuphuka ngokushesha. Uma i-exhaust ingekho ngesikhathi, kuzoba khona umcimbi wezigubhu zebhethri.

IV. Ishaja entantayo isethwe phezulu kakhulu, futhi ukushaja kwamanje kukhulu, okwenza ukuthi i-o2 epuleti elihle isheshise, futhi ayilungile njengenhlanganisela engalungile, futhi ukunyuka kwezinga lokushisa ebhethri nakho kuyashesha kakhulu, ekukhishweni kokukhipha Lapho ingcindezi ifinyelela umshini wokunyathelisa, ibhethri le-VRLA liyakhubazeka. Isizathu sezigubhu zebhethri zemoto kagesi ze-lithium-ion: 1, ikhwalithi yeshaja iphansi, impi yamanani iyabulawa, izinga leshaja liyehla, kusetshenziswa ipuleti elingaphansi, ukulungiswa kabusha noma idivayisi ephansi ephansi, umkhuhlane, ukukhukhuleka kwepharamitha akunembile, ukuze umkhawulo wokushaja ungalawuleki, Ukukhishwa kwegesi kwangaphakathi kwe-extrusion yebhethri ye-lithium kuphumela ekuqhumeni kwebhethri kanye ne-extrusion yebhethri ye-lithium.

I-2, isikhathi sokushaja side kakhulu, abanye abasebenzisi abanalo umqondo wesikhathi, becabanga ukuthi ukufaka ukushaja okuzenzakalelayo okuzenzakalelayo okugcwele, angibuzi, abanye baze bagcwalise izinsuku ezimbili nobusuku obubili, ngisebenzise isikhathi eside, imoto kagesi lithium ion Impilo yebhethri yebhethri izosongelwa. Uma ukushaja okungaphezulu kungaholela enanini elikhulu lepuleti le-electrode yegesi eshaywayo, kubangela ukuthi into esebenzayo yangaphakathi iwe, ifinyeze impilo yebhethri, ukuze ibhethri lingasebenzi, kuthinte ukubola kwe-electrolyte, ukuze izinga lokushisa lebhethri likhuphuke, kwenze kube Isidakamizwa! Imbobo ye-valve ivinjiwe, ithuthukisa ingcindezi yegesi yangaphakathi ibangela ukuba ikesi yebhethri ikhubazeke, futhi ukuhlukana kuyavuvukala. 4, khohlwa ishaja eneshaja, vele uboleke eyodwa, noma umndeni wamashaja amaningana emoto kagesi, lokhu kuvame kakhulu, uhlobo ngalunye lwebhethri yemoto kagesi lunokuxhumana lwalo, inani lamanje, ugesi ohlukile Imoto ingaba nama-voltage ahlukene okushaja, amandla okushaja ahlukile, isikhathi sokushaja semvelo nokusebenza kahle kokushaja kuhlukile, futhi ishaja, ishaja incane, ishaja incane, ishaja incane, ishaja incane enkulu, ukushaja, ukushisa akusalawuleki, kuyoba isigubhu.

Okungenhla ukuhlaziya imbangela yamabhethri e-lithium-ion, amabhethri, izigubhu zebhethri yemoto kagesi. Izinkinga zokuphepha zephakethe lebhethri le-iron phosphate kube yisihloko sokunakwa okuqhubekayo kwabantu, nakuba ubuchwepheshe bebhethri ye-lithium-ion buthuthuka njalo, kodwa izingozi zokuphepha zisekhona. Ukusebenza kokuphepha kwebhethri akunalo iphakethe lebhethri le-lithium-ion elingcono.

Uma kukhona isenzakalo sesikhwama sesigubhu ngesikhathi sokusebenzisa amaphakethe ebhethri e-lithium-ion, uchungechunge oluncane lunconywa ukuthi luthathe indawo yebhethri, ngemva kwakho konke, okubaluleke kakhulu. I-voltage ingaphansi kwe-3V, yenza kuqala i-precharge, yamanje yokushaja ingu-1/10 wesethi yamanje, futhi i-voltage ikhuphukela ku-3V, faka inqubo yokushaja ejwayelekile. Inqubo yokushaja ejwayelekile ithi: Uma i-current ingashintshi, i-voltage yebhethri ikhuphukela ku-4.

20V, shintshela ekushajweni kwengcindezi engaguquki, gcina i-voltage yokushaja engu-4.20V. Ngalesi sikhathi, ukushaja kwamanje kuyancipha kancane kancane, futhi lapho okwamanje kwehla ku-1/10 yesethi yamanje yokushaja, ukushaja kuyaphela.

Lena inqubo evamile yokushajwa kwebhethri ye-lithium-ion, uma ibhethri ye-lithium ion ikhona kudivayisi ehlakaniphile, imodi yayo yokushaja izolawulwa isofthiwe yedivayisi ehlakaniphile.
