Ukwakheka kweibhethri ye-lithium

Ukwakhiwa kwezinto zamabhethri e-lithium ikakhulukazi kuhlanganisa izinto ezinhle ze-electrode, izinto ezingezinhle ze-electrode, izihlukanisi, ama-electrolyte, nama-casings.

1. Phakathi kwezinto ezinhle ze-electrode, izinto ezisetshenziswa kakhulu yi-lithium cobaltate, i-lithium manganate, i-lithium iron phosphate kanye nezinto ze-ternary (ama-polymers we-nickel, i-cobalt ne-manganese).I-electrode eyi-positive ibala ingxenye enkulu (isilinganiso sobuningi bezinto ezingezinhle nezingezinhle zama-electrode ngu-3:1–4:1), ngoba ukusebenza kwempahla ye-electrode eyakhayo kuthinta ngokuqondile ukusebenza kwebhethri ye-lithium-ion, futhi izindleko zayo futhi inquma ngqo izindleko ibhethri.
2. Phakathi kwezinto ezingezinhle ze-electrode, i-graphite yemvelo kanye ne-graphite yokufakelwa okwamanje yizinto eziyinhloko ze-electrode ezimbi.Izinto ze-anode ezihlolwayo zifaka i-nitrides, i-polyaspartic acid, i-tin-based oxides, ama-alloys ethini, izinto ze-nano-anode, nezinye izinhlanganisela ze-intermetallic.Njengenye yezinto ezine ezinkulu zamabhethri e-lithium, izinto ezingezinhle ze-electrode zidlala indima ebalulekile ekuthuthukiseni umthamo webhethri nokusebenza komjikelezo, futhi ziphakathi nendawo emaphakathi embonini yebhethri ye-lithium.
3. Izinto ze-diaphragm ezigxile emakethe ikakhulukazi ama-diaphragm e-polyolefin, enziwe ikakhulukazi nge-polyethylene ne-polypropylene.Kusakhiwo se-separator yebhethri ye-lithium, isihlukanisi singenye yezingxenye ezibalulekile zangaphakathi.Ukusebenza kwesihlukanisi kunquma ukwakheka kwesixhumi esibonakalayo kanye nokumelana kwangaphakathi kwebhethri, okuthinta ngqo umthamo, umjikelezo nokusebenza kokuphepha kwebhethri.Isihlukanisi esisebenza kahle kakhulu sidlala indima ebalulekile ekuthuthukiseni ukusebenza okuphelele kwebhethri.
4. I-electrolyte ngokuvamile yenziwe ngama-high-purity organic solvents, usawoti we-lithium we-electrolyte, izithasiselo ezidingekayo nezinye izinto zokusetshenziswa ngesilinganiso esithile ngaphansi kwezimo ezithile.I-electrolyte idlala indima yokuqhuba ama-ion phakathi kwama-electrode alungile noma angalungile ebhethri ye-lithium, okuyisiqinisekiso samandla kagesi aphezulu namandla athile aphezulu ebhethri ye-lithium ion.
5. Isikhwama sebhethri: ihlukaniswe yaba isikhwama sensimbi, i-aluminium casing, i-nickel-plated iron casing (yamabhethri angamacylindrical), ifilimu ye-aluminium-plastic (iphakheji elithambile), njll., kanye nekepisi yebhethri, ephinde ibe yitheminali ephozithivu nenegethivu yebhethri. ibhethri
6. Umgomo wokusebenza kwebhethri
7. Lapho ibhethri lishajwa, ama-ion e-lithium akhiqizwa ku-electrode ephozithivu yebhethri, futhi ama-ion e-lithium akhiqiziwe aya ku-electrode engeyinhle nge-electrolyte.Isakhiwo sekhabhoni se-electrode engalungile sinezimbotshana eziningi, futhi ama-ion e-lithium afinyelela ku-electrode engalungile ashumekwe kuma-micropores we-carbon layer.Uma i-lithium ion ishumekiwe, amandla okushaja azoba phezulu.Lapho ibhethri likhishwa, ama-ion e-lithium afakwe kungqimba lwekhabhoni ye-electrode engalungile aphuma futhi abuyele ku-electrode eqondile.Lapho ama-ion e-lithium engeziwe abuyela ku-electrode ephozithivu, ayanda amandla okuphuma.Ngokuvamile, umthamo wokukhipha ubhekisela kumthamo wokukhipha.Ngesikhathi sokushaja nokukhipha ibhethri ye-lithium, i-lithium ion isesimweni sokunyakaza ukusuka ku-electrode enhle kuya ku-electrode engalungile.Uma isithombe sebhethri ye-lithium siqhathaniswa nesihlalo esinyakaziswayo, iziphetho ezimbili zesihlalo esinyakazayo ama-electrode ebhethri alungile futhi angalungile, futhi i-lithium ion ifana nabasubathi, egijima emuva naphambili phakathi kweziphetho ezimbili zesihlalo esinyakazayo. .Ngakho-ke amabhethri e-lithium abizwa nangokuthi amabhethri e-rocking chair.
