I-lithium iron phosphate njengenye yezinhlobo zebhethri zamanje zezimoto zikagesi, ezibonakala ngokuzinza kwayo okushisayo okuzinzile, izindleko zokukhiqiza aziphezulu, impilo ende yesevisi, njll. Nokho, ukumelana kwayo okuphansi kwezinga lokushisa kuphansi kakhulu, esimweni. ye-minus 10 degrees, nakuba ibhethri ingasetshenziswa ngokujwayelekile, kodwa ukusebenza kahle kokushaja kuzoncishiswa kakhulu.
Ngokuba i-lithium iron phosphate ebusika bubi kakhulu lesi sitatimende, empeleni, izinga lokushisa eliphansi lasebusika i-lithium iron phosphate liyoba likhulu kune-ternary lithium battery decay, kodwa aliyona enkulu.Ngaphansi kwezimo ezifanayo, uma imoto efakwe amabhethri e-ternary lithium izoncipha ngo-25% ngenxa yebanga lokushisa eliphansi lasebusika, kuyilapho i-lithium iron phosphate ingase ifinyelele ku-30%.Igebe phakathi kwalokhu kokubili linjalo nje, futhi alilikhulu njengegebe elihunyushwa abanye abantu ku-inthanethi.Ngaphezu kwalokho, igebe alinqunywa ngokuphelele izici zebhethri ezizalwa nazo.
Umehluko phakathi kwe-lithium iron phosphate kanye ne-ternary lithium battery comparison
Ukuminyana kwamandla ebhethri kuyinkomba ethinta ukusebenza kwebanga lezimoto zamandla amasha.Ukuminyana kwamandla ebhethri ye-lithium iron phosphate kulinganiselwa ku-110Wh/kg kuphela, kuyilapho ukuminyana kwamandla ebhethri le-lithium cell ngokuvamile kungu-200Wh/kg.okungukuthi, isisindo esifanayo sebhethri, i-ternary lithium battery density yizikhathi ezingu-1.7 kunebhethri ye-lithium iron phosphate, ibhethri ye-lithium ye-ternary ingaletha ububanzi obude bezimoto ezintsha zamandla.
Ibhethri le-lithium iron phosphate njengamanje liwukuzinza okungcono kakhulu okushisayo kwebhethri lamandla, mayelana nokuphepha uma kuqhathaniswa namabhethri e-ternary lithium anezinzuzo eziphelele.Ibhethri ye-lithium iron phosphate electrothermal peak kufika ku-350 ℃, ukwakheka kwamakhemikhali kwangaphakathi kwebhethri kudinga ukufinyelela ku-500 ~ 600 ℃ ngaphambi kokuba iqale ukubola;kuyilapho ukuqina okushisayo kwebhethri ye-ternary lithium ukusebenza kuvame kakhulu, izoqala ukubola cishe ku-300 ℃. Ibhethri ye-lithium iron phosphate okwamanje iyindlela engcono kakhulu yokushisa yebhethri yamandla, mayelana nokuphepha uma kuqhathaniswa namabhethri e-ternary lithium anezinzuzo eziphelele. .Ibhethri ye-lithium iron phosphate electrothermal peak kufika ku-350 ℃, ukwakheka kwamakhemikhali kwangaphakathi kwebhethri kudinga ukufinyelela ku-500 ~ 600 ℃ ngaphambi kokuba iqale ukubola;kuyilapho ukuqina okushisayo kwebhethri ye-ternary lithium ukusebenza kuvame kakhulu, izoqala ukubola cishe ku-300 ℃. Ibhethri ye-lithium iron phosphate okwamanje iyindlela engcono kakhulu yokushisa yebhethri yamandla, mayelana nokuphepha uma kuqhathaniswa namabhethri e-ternary lithium anezinzuzo eziphelele. .Ibhethri ye-lithium iron phosphate electrothermal peak kufika ku-350 ℃, ukwakheka kwamakhemikhali kwangaphakathi kwebhethri kudinga ukufinyelela ku-500 ~ 600 ℃ ngaphambi kokuba iqale ukubola;kuyilapho ukuqina okushisayo kwebhethri ye-ternary lithium ukusebenza kuvame kakhulu, izoqala ukubola cishe ku-300 ℃. Ibhethri ye-lithium iron phosphate okwamanje iyindlela engcono kakhulu yokushisa yebhethri yamandla, mayelana nokuphepha uma kuqhathaniswa namabhethri e-ternary lithium anezinzuzo eziphelele. .Ibhethri ye-lithium iron phosphate electrothermal peak kufika ku-350 ℃, ukwakheka kwamakhemikhali kwangaphakathi kwebhethri kudinga ukufinyelela ku-500 ~ 600 ℃ ngaphambi kokuba iqale ukubola;kuyilapho ukuqina okushisayo kokusebenza kwebhethri le-lithium kuvamile kakhulu, kuzoqala ukubola cishe ku-300 ℃.
Amabhethri e-Ternary lithium asebenza kahle kakhulu.Idatha yokuhlola ikhombisa ukuthi umehluko phakathi kwakho kokubili awumuningi uma ishaja ngaphansi kwezimo eziyi-10 ℃, kodwa ngaphezu kuka-10 ℃ izosuka, ekushajweni okungu-20 ℃, isilinganiso esiqhubekayo samanje samabhethri e-ternary lithium ngu-52.75%, isilinganiso samanje se-lithium. i-iron phosphate ingu-10.08%, eyokuqala izikhathi ezi-5 kokugcina.
Impilo yomjikelezo webhethri ye-lithium iron phosphate ingcono kunebhethri ye-lithium ye-ternary, impilo yethiyori ye-lithium yebhethri izikhathi ezingama-2000, kodwa ngokuyisisekelo imijikelezo eyi-1000, ukubola komthamo kuya ku-60%.Ngisho noma imboni ingcono kakhulu i-Tesla, emva kwezikhathi ze-3000 ingagcina amandla angu-70% kuphela, kuyilapho ibhethri ye-lithium iron phosphate ngemva komjikelezo ofanayo womjikelezo, kodwa futhi i-80% yomthamo.
Ngokuphambene, ukuphepha kwebhethri ye-lithium iron phosphate, impilo ende, ukumelana nokushisa okuphezulu;I-ternary lithium battery lightweight, high charger performance, low lokushisa ukumelana.Ngakho-ke, umehluko phakathi kokubili okukhiqizwa yisikhathi nendawo yokuguquguquka kwazo okuhambisanayo kuyisizathu sokuhlalisana.
