Ibhethri ye-lithium-ion (eyaziwa lapha ngokuthi ibhethri ye-lithium) ingena ngokushesha emakethe yomthombo wamandla wezinto eziphathwayo zikagesi nezikagesi kusukela ukuthengiswa kwayo ngenxa yokuphakama kwe-voltage ephezulu, umthamo omkhulu, impilo ende kanye nomphumela wokukhumbula, futhi yangena ngokushesha emakethe yomthombo wamandla wemishini kagesi ephathwayo selokhu yathengiswa. Okukhulu. Ibhethri ye-lithium iyinto esebenzisekayo kagesi, impilo icishe ibe ngu-3A.

Amabhethri e-lithium ngemva kodoti, njengokwelashwa okungafanele, i-hexafluorophosphate equkethwe ku-hexafluorophosphate, carbonate organic matter, ne-cobalt, ithusi, njll., nakanjani ayoba izinsongo ezingaba khona zokungcoliswa kwemvelo. Ngakolunye uhlangothi, i-cobalt, i-lithium, ithusi namapulasitiki kumabhethri e-lithium adoti ayimithombo ebalulekile, enenani eliphakeme kakhulu lokutakula.

Ngakho-ke, ukwelashwa okuphumelelayo kwesayensi kwamabhethri e-lithium, akugcini nje kuphela izinzuzo ezibalulekile zemvelo, kodwa futhi kunezinzuzo ezinhle zezomnotho. Ibhethri ye-lithium ngokuyinhloko yakhiwe izindlu, i-electrode eqondile, i-electrode engalungile, ne-electrolyte kanye ne-membrane. I-electrode enhle ihlanganisa i-lithium cobalt powder ezinhlangothini ezimbili ze-aluminium foil concentration fluid nge-PVDF eboshiwe; isakhiwo se-electrode esingesihle sifana ne-electrode enhle, futhi sihlanganiswe ne-carbon powder ezinhlangothini zombili zomqoqi we-foil yethusi.

Njengamanje, ucwaningo lwemithombo yebhethri ye-lithium imfucuza lugxile kakhulu ekubuyiseni amanani aphezulu ensimbi ye-cobalt ne-lithium, nokuhlukaniswa nokubuyiselwa kwezinto ezingezinhle ze-electrode. Ukuze kuncishiswe ukuthuthuka komnotho osheshayo, ukushoda kwezinsiza okwandayo kanye nokungcoliswa kwemvelo, kanye nesamba sengxenye yokugaywa kabusha kanye nokusetshenziswa kwezinto ezilahlwayo sekuyisivumelwano somhlaba wonke. I-Copper (okuqukethwe cishe kwe-35%) ku-electrode engalungile yebhethri ye-lithium imfucuza isetshenziswa kabanzi ebalulekile yokukhiqiza impahla eluhlaza, enamathele ku-toner, engasetshenziswa njengezithasiselo ezifana namapulasitiki, irabha.

Ngakho-ke, iyasebenza ekuhlukaniseni okusebenzayo kwebhethri ye-lithium engalungile eyenza izinto, futhi ithuthukiswa ukuze kwandiswe insiza yokukhansela, iqede umthelela wayo ohambisanayo kwezemvelo. Isistimu yezinsiza zebhethri ye-lithium evame ukusetshenziswa ihlanganisa i-metallurgy emanzi, i-metallurgy yokwenza umlilo kanye ne-mechanical physics. Uma kuqhathaniswa nokumanzi nomlilo, i-mechanical physics ayidingi ukusebenzisa ama-reagents amakhemikhali, futhi ukusetshenziswa kwamandla okuphansi kuyindlela evumelana nemvelo nephumelelayo.

Ngokusekelwe ezicini zesakhiwo se-electrode engalungile yebhethri ye-lithium, umbhali usebenzisa isikrini esiphukile kanye nenqubo yokuhlanganiswa kokuhlunga komoya ukuze ahlukanise isifundo sokucebisa ukuze kuzuzwe ukuhlukaniswa okusebenzayo okuphezulu nokubuyiselwa kwethusi eline-anematic ne-toner. Ibhethri ye-lithium yokusaphaza izinto ezinhle nezingezinhle zokutakula Umgomo osebenzayo: Ngokusekelwe esakhiweni se-electrode esihle nesibi sebhethri ye-lithium kanye nokwakheka kwayo kwempahla yethusi ne-toner, yakhiwe ingxenyenamba yesando, ukuhlolwa kokudlidliza kanye nenqubo yokuhlanganisa yokuhlunga komoya ukuze kumoshwe i-electrode eyi-lithium engalungile yebhethri Material yokuhlukaniswa nokugaywa kabusha. Ukuhlolwa kusebenzisa amasampula okuhlola e-ICP-AES kanye nokunambitha kwensimbi okwehlukanisa imikhiqizo ethuthukisiwe.

Imiphumela yabonisa ukuthi ngemva kokuphulwa kwempahla yokumboza, ithusi lalingu-92.4% endaweni ephukile enkulu kuno-0.250 mm, kuyilapho usayizi wezinhlayiyana ungaphansi kuka-0.

U-125 mm ubungu-96.6%, ongatholwa ngokuqondile. Entweni ephukile enosayizi wezinhlayiyana ongu-0.

125 kuya ku-0.250 mm, ibanga lethusi liphansi, futhi ukuhlukaniswa okuphumelelayo kokuthola ithusi ne-toner kungafinyelelwa ngokuhlunga kokugeleza komoya; ngesikhathi sokuhlunga ukugeleza komoya, izinga lokugeleza kwegesi elisebenzayo ngu-1.00m / s, ithusi Izinga lokutakula lingama-92.

3%, ngokunambitheka kuka-84.4%. Amagama angukhiye: ibhethri ye-lithium-ion imfucuza; izinto ezingezinhle ze-electrode; ephukile; uhlobo lokugeleza komoya.

Imishini yokubuyisela i-electrode enhle nebi yebhethri ye-lithium yemfucuza: 1) Ngokusando, ukuhlolwa kokudlidliza kanye nenqubo yokuhlunga ukugeleza komoya kungabona ukusetshenziswa kwensiza yethusi yensimbi ne-toner kumpahla ye-electrode engalungile yebhethri ye-lithium. I-2) Izinto ezingalungile ze-electrode zingakwazi ukubona ngokuphumelelayo ukucwecwa okuhlangene phakathi kwe-toner ne-foil yethusi, bese i-foil yethusi ne-carbon powder zihlukaniswa ekuqaleni ngesisefo sokudlidliza sobukhulu bezinhlayiyana kanye nomehluko womumo. Imiphumela yokuhlukaniswa kwesando kanye nesefo ibonisa ukuthi i-copper ne-carbon powder inothiswa ngosayizi wezinhlayiyana ezingaphezu kuka-0.

250 mm kanye nosayizi wezinhlayiyana ezingaphansi kuka-0.125 mm, ngokulandelana, futhi amabanga aphezulu afinyelela ku-92.4% no-96.

6%, futhi bangathumela ngqo amabhizinisi angezansi. sebenzisa. 3) Okwezinhlayiya ezichotshozwayo ezinosayizi wezinhlayiyana ongu-0.

125 kuya ku-0.250 mm, ithusi liphansi, ukuhlunga ukugeleza kwegesi kungasetshenziswa ukufeza ukuhlukana okuphumelelayo phakathi kwethusi ne-toner, futhi uthole umphumela omuhle wokutakula lapho isivinini sokugeleza komoya singu-1.00 m / s.

Izinga lokubuyisela ithusi lensimbi lingafinyelela ku-92.3%, kanti umkhiqizo ungama-84.4%.

Lo mshini usetshenziselwa ikakhulukazi abakhiqizi bebhethri ye-lithium-ion, ukuhlukanisa i-aluminium Bo, ama-hoops ethusi kumashidi e-electrode alahliwe, kanye nokuhlukanisa izinto ezisetshenziswayo zama-electrode ezinhle nezingezinhle ukuze zisetshenziswe. Imishini ephelele isetshenziswa esimweni sokucindezela okubi, akukho rhudo lothuli, ukusebenza kahle kokuhlukanisa kungafinyelela ngaphezu kwama-98%. .
