Batirin lithium na uku dalithium iron phosphate baturasu ne manyan nau'ikan batirin lithium guda biyu da ake amfani da su a halin yanzu a cikin motocin lantarki, tsarin ajiyar makamashi da sauran na'urorin lantarki. Amma ka fahimci halaye da bambancinsu? Abubuwan sinadaran su, halayen aiki da filayen aikace-aikacen sun bambanta sosai. Bari mu ƙara koyo game da su tare da Heltec.
Haɗin kayan abu:
Batirin lithium na ternary: Kyakkyawan kayan lantarki yawanci nickel cobalt manganese oxide (NCM) ko nickel cobalt aluminum oxide (NCA), wanda ya ƙunshi nickel, cobalt, manganese ko nickel, cobalt, aluminum da sauran abubuwan ƙarfe oxides, da korau. Electrode gabaɗaya graphite ne. Daga cikin su, ana iya daidaita rabon nickel, cobalt, manganese (ko aluminum) bisa ga ainihin bukatun.
Lithium iron phosphate baturi: lithium iron phosphate (LiFePO₄) ana amfani da shi azaman tabbataccen lantarki abu, kuma graphite kuma ana amfani da shi ga korau electrode. Abubuwan da ke tattare da sinadaran sa suna da inganci, kuma baya dauke da karafa masu nauyi da karafa da ba kasafai ba, wadanda suka fi dacewa da muhalli.
Yin caji da fitarwa:
Batirin lithium na ternary: saurin caji da saurin fitarwa, na iya daidaitawa zuwa babban cajin halin yanzu da fitarwa, dacewa da kayan aiki da yanayin yanayi tare da manyan buƙatu don saurin caji, kamar motocin lantarki waɗanda ke goyan bayan caji mai sauri. A cikin ƙananan yanayin zafi, cajinsa da aikin fitarwa shima yana da kyau sosai, kuma asarar iya aiki kadan ne.
Lithium iron phosphate baturi: in mun gwada jinkirin caji da saurin fitarwa, amma cajin sake zagayowar barga da aikin fitarwa. Yana iya goyan bayan caji mai girma kuma ana iya cajin shi cikakke cikin sa'a 1 a cikin sauri, amma caji da fitarwa yawanci yawanci kusan 80% ne, wanda ya ɗan yi ƙasa da na batirin lithium na ternary. Ƙarƙashin ƙananan yanayin zafi, aikin sa yana raguwa sosai, kuma ƙimar ƙarfin baturi na iya zama kawai 50% -60%.
Yawan makamashi:
Baturin lithium na ternary: Yawan kuzarin yana da girma, yawanci yana kaiwa sama da 200Wh/kg, kuma wasu samfuran ci-gaba na iya wuce 260Wh/kg. Wannan yana ba da damar batirin lithium na ternary don adana ƙarin kuzari a girma ɗaya ko nauyi, yana ba da tsayin tuki don na'urori, kamar a cikin motocin lantarki, waɗanda zasu iya tallafawa motocin tafiya mai nisa.
Lithium iron phosphate baturi: Yawan kuzari yana da ɗan ƙaramin ƙarfi, gabaɗaya kusan 110-150Wh/kg. Don haka, don cimma iyakar tuƙi iri ɗaya kamar batir lithium na ternary, batir phosphate na lithium baƙin ƙarfe na iya buƙatar girma ko nauyi.
Rayuwar zagayowar:
Baturin lithium na ternary: Rayuwar zagayowar gajeru ce, tare da adadin tsarin zagayowar kusan sau 2,000. A ainihin amfani, ƙarfin yana iya lalacewa zuwa kusan 60% bayan zagayowar 1,000. Amfani mara kyau, kamar wuce kima ko fitarwa, da amfani da shi a yanayin zafi mai zafi, zai ƙara lalata baturin.
Lithium iron phosphate baturi: Tsawon rayuwa, tare da caji sama da 3,500 da zagayowar fitarwa, kuma wasu batura masu inganci na iya kaiwa fiye da sau 5,000, wanda yayi daidai da fiye da shekaru 10 na amfani. Yana da kwanciyar hankali mai kyau, kuma shigarwa da cirewar lithium ions ba su da tasiri sosai a kan lattice, kuma yana da kyau sake dawowa.
Tsaro:
Baturin lithium na ternary: rashin kwanciyar hankali mai zafi, mai sauƙin haifar da guduwar zafi a ƙarƙashin babban zafin jiki, ƙarin caji, gajeriyar kewayawa da sauran yanayi, yana haifar da babban haɗarin konewa ko ma fashewa. Duk da haka, tare da ci gaban fasaha da ƙarfafa matakan tsaro, kamar yin amfani da ƙarin tsarin sarrafa baturi da inganta tsarin batir, amincinsa kuma yana inganta kullum.
Lithium baƙin ƙarfe phosphate baturi: mai kyau thermal kwanciyar hankali, da m electrode abu ba sauki don saki oxygen a high zafin jiki, kuma ba zai fara bazuwa har sai 700-800 ℃, kuma ba zai saki oxygen kwayoyin a lokacin da fuskantar tasiri, huda, short kewaye da kuma wasu yanayi, kuma ba shi da saurin konewa, tare da babban aikin aminci.
Farashin:
Batirin lithium na ternary: saboda ingantaccen kayan lantarki yana ƙunshe da abubuwa masu tsada kamar nickel da cobalt, kuma buƙatun tsarin samarwa suna da yawa, kuma buƙatun muhalli ma sun fi ƙarfi, don haka farashin yana da yawa.
Lithium iron phosphate baturi: farashin albarkatun kasa yana da ƙananan ƙananan, tsarin samarwa yana da sauƙi mai sauƙi, kuma yawan farashi yana da wasu abũbuwan amfãni. Misali, a cikin sabbin motocin makamashi, samfura masu sanye da batirin lithium iron phosphate sau da yawa suna da ƙarancin farashi.
