Ukuqala kokuqhuma kwebhethri le-lithium le-NMC
Manje sekungu-2020. Ngokukhuphuka okuqhubekayo kwamabhethri e-lithium we-ternary, ubuchwepheshe bamabhethri e-lithium we-ternary manje aqhubeka futhi ethuthuka. Izinto zokwakhiwa kwe-Ternary ezinamandla amakhulu kakhulu zithatha indawo ye-iron phosphate kancane kancane ngokuzinza okungcono. lithium ibhethri. Yize impahla ye-ternary iletha amandla aphezulu ebhethri ye-ternary lithium, ukuzinza kwayo sekuyinselelo enkulu. Endaweni enezinga lokushisa eleqile, ibhethri lizoqhuma, futhi ezimweni ezinzima Kuzoze kube nokuqhuma. Ingabe amathuba okuqhuma kwebhethri ye-lithium ye-ternary aphezulu kakhulu? Namuhla sizobheka ukuthi kungenzeka yini ukuqhuma kwebhethri ye-lithium yebhethri.

Ibhethri le-Ternary lithium
Amathuba okuqhuma kwebhethri ye-lithium ye-ternary
Amathuba aphezulu kakhulu. Lapho ibhethri selikhokhiswe ngokweqile, ukukhishwa ngokweqile kwe-lithium ku-electrode enhle kuzoshintsha ukwakheka kwe-electrode enhle, futhi i-lithium eningi kakhulu ngeke ikwazi ukufakwa ku-electrode engeyinhle, futhi izobangela kalula i-lithium ebusweni ye-electrode engemihle, futhi lapho i-voltage ifinyelela Ngaphezu kuka-4.5V, i-electrolyte izobola ukukhiqiza inani elikhulu legesi. Konke okungenhla kungadala ukuqhuma. Uphawu ngaphambi kokuqhuma ukushisa nokuguquguquka kokushaja, futhi imiphumela engathandeki yisifunda esifushane, isifunda esivulekile, ngisho nokuqhuma.

Yikuphi ukuqhuma okunamandla kakhulu kwebhethri ye-lithium yebhethri noma ibhethri le-lithium le-18650?
Ngemuva kwakho konke, ibhethri le-lithium ibhethri nje, hhayi ibhomu. Noma ukuphepha kwe-18650 lithium battery kuyimbi kakhulu, ukusebenza kwayo kokukhipha kuhamba kancane. Okungenani, isha ngamandla ngemuva kokuqhuma. Lokho okubizwa ngokuthi “ukuqhuma” kumane kungukunyakaza okuncane lapho kuqhuma. Isiphetho sokugcina ngukuthi noma ngabe amabhethri e-lithium angama-2,000 3,000 kuya ku-18650 ahlanganiswe ndawonye, amandla wokuqhuma asenqunyelwe, futhi ngokuyisisekelo ngeke abulawe. Ngakho-ke, empilweni yansuku zonke, kufanele uqaphele lapho usebenzisa amadivayisi anamabhethri e-lithium ayi-XNUMX.
Inqubo yokulungiselela amabhethri e-lithium ivuthwe kakhulu, ngaphezu kokusebenza okuthuthuke kakhulu, ukuphepha kwayo nakho kuphelele kakhulu. Ukuze uvimbele ukuqhuma kwekesi lensimbi evaliwe, kufakwa i-valve yokuphepha ngaphezulu kwebhethri le-18650. Lokhu ukucushwa okujwayelekile kwebhethri ngalinye le-18650 kanye nesithiyo esibaluleke kakhulu sokuqhuma ukuqhuma. Lapho ingcindezi yangaphakathi yebhethri iphakeme kakhulu, i-valve yokuphepha ngaphezulu kwebhethri ivula umsebenzi wokukhipha nokucindezela ukucindezela ukuqhuma.

Ukukhipha okujulile ibhethri le-lithium-ion
Kodwa-ke, amabhethri e-lithium we-ternary asenezinkinga eziningi maqondana nokuphepha. Engozini yemoto, umthelela wamandla angaphandle uzolimaza i-diaphragm yebhethri futhi ubangele isifunda esifushane. Ukushisa okukhishwe ngesikhathi sesifunda esifushane kuzokwenza ukuthi ibhethri likhiqize ukushisa futhi kwandise izinga lokushisa kwebhethri libe ngaphezu kwe-300 ° C. Ukuzinza okushisayo kwe-ternary lithium battery akukubi, futhi ama-molecule e-oxygen azobola lapho ephethwe ngaphansi kuka-300 ℃. Kuzoba kancane ngemuva kokuhlangana nezinto ezishisa i-electrolyte nekhabhoni. Ukushisa okukhiqizwayo kubhebhethekisa ukubola kwe-electrode enhle. Esikhathini esifushane kakhulu Izoshisa ngaphakathi. Uma kuqhathaniswa, elinye ibhethri le-lithium iron phosphate elisetshenziswa kakhulu lingagcinwa ku-700-800 ° C ngaphandle kokubola kwama-molecule e-oxygen futhi liphephe kakhulu.
Ngemininingwane eminingi Ungakhuphula kanjani impilo yebhethri le-lithium polymer sicela uhlole izindatshana zethu zakamuva.
