Makhe sihlolisise izizathu zokuba kutheni i-LiFePo4 inokuba nemeko eyomeleleyo yokukhetha kuneebhetri ze-lithium ze-ternary, kwaye sifumane ukuqonda malunga nokuba yeyiphi na ibhetri enokuzisa kwiiprojekthi zakho. Funda ukuze ufumane okungakumbi malunga ne-LiFePO4 kunye neebhetri ze-lithium ze-ternary, ngoko unokwenza isigqibo esinolwazi xa uqwalasela isisombululo sakho samandla esilandelayo!
Ziziphi iibhetri zeLithium Iron Phosphate kunye neTerry Lithium?
I-Lithium Phosphate kunye ne-ternary lithium iibhetri zimbini zezona ntlobo zidumileyo zeebhetri ezinokutshajwa kwakhona. Banikezela ngeenzuzo ezininzi, ukusuka kumandla aphezulu ukuya kubomi obude. Kodwa yintoni eyenza i-LiFePO4 kunye neebhetri ze-lithium ze-ternary zikhethekileyo?
I-LiFePO4 yenziwe ngamaqhekeza e-Lithium Phosphate ahlanganiswe ne-carbonates, i-hydroxides, okanye i-sulfates. Le ndibaniselwano inika isethi ekhethekileyo yeepropati ezenza ukuba ibe yikhemistri yebhetri efanelekileyo kwizicelo zamandla aphezulu njengezithuthi zombane. Inobomi bomjikelo obugqwesileyo- okuthetha ukuba inokutshajwa kwaye ikhutshwe amawakawaka amaxesha ngaphandle kokuthotywa. Ikwanazo nozinzo oluphezulu lwe-thermal kunezinye iikhemistri, okuthetha ukuba akunakufane kwenzeke ukutshisa kakhulu xa isetyenziswa kwizicelo ezifuna ukukhutshwa rhoqo kwamandla aphezulu.
Iibhetri ze-lithium ze-ternary zenziwe ngendibaniselwano ye-lithium nickel cobalt manganese oxide (NCM) kunye negraphite. Oku kuvumela ibhetri ukuba ifezekise uxinano lwamandla ezinye iikhemistri ezingakwaziyo ukuhambelana nazo, zizenze zilungele usetyenziso olufana nezithuthi zombane. Iibhetri ze-lithium ze-ternary nazo zinobomi obude kakhulu, zinokuhlala ukuya kuthi ga kwimijikelezo engama-2000 ngaphandle kokuthotywa okubalulekileyo. Bakwanawo amandla abalaseleyo okuphatha, okubavumela ukuba bakhuphe ngokukhawuleza amanani aphezulu angoku xa kufuneka.
Yintoni iNqanaba loMahluko waMandla phakathi kweLithium Phosphate kunye neebhetri zeTernary Lithium?
Ubuninzi bamandla ebhetri bumisela ukuba mangakanani amandla enokuthi iwagcine kwaye iwahambise xa kuthelekiswa nobunzima bayo. Le nto ibalulekileyo xa uqwalasela izicelo ezifuna ukukhutshwa kwamandla aphezulu okanye ixesha elide ukusuka kwi-compact, umthombo okhanyayo.
Xa uthelekisa ukuxinana kwamandla e-LiFePO4 kunye neebhetri ze-lithium ze-ternary, kubalulekile ukuqaphela ukuba iifomathi ezahlukeneyo zinokubonelela ngamanqanaba ahlukeneyo amandla. Ngokomzekelo, iibhetri ze-asidi ezikhokelayo zinomlinganiselo othile wamandla we-30-40 Wh / Kg ngelixa i-LiFePO4 ilinganiswe kwi-100-120 Wh / Kg - phantse kathathu ngaphezu komlingani wayo we-asidi ehamba phambili. Xa kuqwalaselwa iibhetri ze-ternary ze-lithium-ion, ziqhayisa ngomlinganiselo othe kratya ophezulu we-160-180Wh/Kg.
