Ngaba ujonge ibhetri ethembekileyo nesebenzayo enokusetyenziswa kwiintlobo ngeentlobo zezicelo? Sukujonga kude kuneebhetri ze-lithium phosphate (LiFePO4). I-LiFePO4 yeyona ndlela ithandwayo kakhulu kuneebhetri ze-ternary lithium ngenxa yeempawu zayo ezimangalisayo kunye nokusingqongileyo.
Makhe sihlolisise izizathu zokuba kutheni iLiFePo4 inokuba necala elinamandla lokukhetha kuneebhetri ze-ternary lithium, size sifumane ulwazi malunga nokuba loluphi na uhlobo lwebhetri olunokuzisa ntoni kwiiprojekthi zakho. Qhubeka ufunda ukuze ufumane okungakumbi malunga neebhetri ze-LiFePO4 kunye ne-ternary lithium, ukuze ukwazi ukwenza isigqibo esinolwazi xa ucinga ngesisombululo sakho esilandelayo samandla!
Zenziwe Ngantoni iibhetri zeLithium Iron Phosphate kunye neTernary Lithium?
Iibhetri zeLithium Phosphate kunye neebhetri ze-ternary lithium zezona zimbini zezona ntlobo zidumileyo zeebhetri ezinokutshajwa kwakhona. Zibonelela ngeenzuzo ezininzi, ukusuka kubuninzi bamandla ukuya kubomi obude. Kodwa yintoni eyenza iibhetri zeLiFePO4 kunye neebhetri ze-ternary lithium zibe zekhetheke kangaka?
I-LiFePO4 yenziwe ngamasuntswana e-Lithium Phosphate axutywe nee-carbonates, ii-hydroxides, okanye ii-sulfates. Olu dibaniso luyinika iseti ekhethekileyo yeempawu ezenza ukuba ibe yikhemikhali yebhetri efanelekileyo kwizicelo zamandla aphezulu njengezithuthi zombane. Inobomi obuhle kakhulu bomjikelo - oko kuthetha ukuba inokutshajwa kwaye ikhutshwe amawakawaka amaxesha ngaphandle kokuwohloka. Ikwanozinzo oluphezulu lobushushu kunezinye iikhemistri, oko kuthetha ukuba ayinakushushu kakhulu xa isetyenziswa kwizicelo ezifuna ukukhutshwa kwamandla aphezulu rhoqo.
Iibhetri ze-ternary lithium zenziwe ngomxube we-lithium nickel cobalt manganese oxide (NCM) kunye ne-graphite. Oku kuvumela ibhetri ukuba ifikelele kubuninzi bamandla obungenakufaniswa nezinye iikhemistri, nto leyo eyenza ukuba ilungele ukusetyenziswa njengezithuthi zombane. Iibhetri ze-ternary lithium nazo zinobomi obude kakhulu, zinokuhlala imijikelo engama-2000 ngaphandle kokonakala okukhulu. Zikwanazo nobuchule obuhle bokuphatha amandla, nto leyo ebavumela ukuba bakhuphe ngokukhawuleza umbane ophezulu xa kufuneka.
Zithini iiMpawu zamandla phakathi kweebhetri zeLithium Phosphate kunye neeTernary Lithium?
Ubuninzi bamandla ebhetri bumisela ukuba ingakanani amandla enokuyigcina kwaye iwanike xa kuthelekiswa nobunzima bayo. Le yinto ebalulekileyo xa ucinga ngezicelo ezifuna amandla aphezulu okanye ixesha elide ukusuka kumthombo omncinci nolula.
Xa kuthelekiswa uxinano lwamandla eebhetri zeLiFePO4 kunye ne-ternary lithium, kubalulekile ukuqaphela ukuba iifomathi ezahlukeneyo zinokubonelela ngamanqanaba ahlukeneyo amandla. Umzekelo, iibhetri ze-lead acid zemveli zinomlinganiselo othile wamandla we-30–40 Wh/Kg ngelixa iLiFePO4 ilinganiswe kwi-100–120 Wh/Kg – phantse kathathu ngaphezulu kune-lead acid counterpart yayo.
