Abavelisi beebhetri zamandla bathetha ngeenzuzo zeebhetri ze-lithium iron phosphate xa kuthelekiswa neebhetri ze-lead-acid
Ibhetri ye-lithium yentsimbi ye-phosphate ikwayibhetri ye-lithium, eneneni ilisebe le-lithium ion ibhetri, iqulethe i-lithium manganese oxide, i-lithium cobalt oxide kunye ne-ternary lithium battery. Ukusebenza kwayo kubaluleke kakhulu kwizicelo zamandla. Ikwabizwa ngokuba yibhetri ye-lithium yesinyithi yamandla ebhetri, ekwabizwa ngokuba yibhetri yentsimbi. Ke ngoko, inzuzo yeebhetri ze-lithium iron phosphate ibhekisa ikakhulu ekukhuselekeni nasekuzinzeni kwabo xa kuthelekiswa nezinye iibhetri kwizicelo zamandla. Ngandlela thile, iya kuba nezibonelelo ngaphezulu kweebhetri ze-lithium zebhetri kunye neebhetri ze-lead-acid.
Okokuqala, iibhetri ze-lithium zentsimbi ye-phosphate zinobushushu obungcono kwaye zinokumelana namaqondo obushushu ukusuka kwi-350 ° C ukuya kwi-500 ° C, ngelixa i-lithium manganate / cobalt oxide ihlala ijikeleze i-200 ° C kuphela. Imathiriyeli yebhetri ye-lithium ephuculweyo nayo iya kuba kwi-200 ° C.
Okwesibini, iibhetri ze-lithium iron phosphate zinobomi obude bomjikelo kuneebhetri ze-lead-acid kunye neeternary lithium. “Ubomi bomjikelezo” webhetri ye-lead-acid kuphela malunga namaxesha angama-300, kwaye ubuninzi ngamaxesha angama-500; Ngelixa ubomi bethiyori yebhetri ye-lithium yebhetri inokufikelela kumaxesha angama-2000, kodwa xa isetyenziswa kaninzi malunga namawaka ali-1000, umthamo uya kwehla uye kuma-60%. Kwaye ubomi bokwenene be-lithium iron phosphate lithium ibhetri ukuya kumaxesha angama-2000. Ngeli xesha, kusekho i-95% yomthamo, kwaye ubomi bayo bomjikelo wethiyori bunokufikelela ngaphezulu kwamaxesha angama-3000.
Okwesithathu, kukho iingenelo ezininzi xa kuthelekiswa neebhetri ze-lead-asidi:
1. Umthamo omkhulu. Iseli ye-3.2V inokwenziwa kwi-5Ah ~ 1000 Ah (1 Ah = 1000m Ah), kunye neseli ye-2V yebhetri ye-lead-acid ihlala i-100Ah ~ 150 Ah.
2. Ubunzima obulula. Umthamo webhetri ye-lithium yentsimbi ye-phosphate yomthamo ofanayo ngu-2/3 wevolumu yebhetri ye-lead-acid, kwaye ubunzima buyi-1/3 yokugqibela.
3. Ukutshaja ngokukhawuleza ukukwazi. Ukuqala kwangoku kwebhetri ye-lithium yensimbi ye-phosphate inokufikelela kwi-2C, enokuqonda ukutshaja okuphezulu; imfuno yangoku yebhetri ye-lead-acid idla ngokuba phakathi kwe-0.1C kunye ne-0.2C, kwaye ukutshaja ngokukhawuleza akunakufezekiswa.
4. Ukukhuselwa kwendalo. Iibhetri ze-lead-asidi zineentsimbi ezininzi ezinzima, eziya kuvelisa ulwelo olulahlwayo. Iibhetri zentsimbi ye-phosphate ibhetri ayiqulathanga naziphi na izinyithi ezinzima, kwaye akukho kungcoliseka kwemveliso kunye nokusetyenziswa.
5. Ukusebenza kwexabiso eliphezulu. Nangona iibhetri ze-lead-acid zitshiphu kunezinto, ixabiso lokuthenga liphantsi kuneebhetri zentsimbi ye-phosphate, kodwa ngokubhekisele kubomi benkonzo kunye nokugcinwa kwesiqhelo, azikho njengoqoqosho njengeebhetri ze-lithium iron phosphate. Iziphumo zesicelo ezibonakalayo zibonisa ukuba ukusebenza kweendleko zebhetri ye-lithium iron phosphate kungaphezulu kwamaxesha ama-4 eebhetri ze-lead-acid.
Nangona uluhlu lwesicelo lweebhetri ze-lithium iron phosphate lubonakaliswe ikakhulu kwicala lamandla, kwithiyori lunokwandiswa kwiindawo ezininzi, kunokwenzeka ukunyusa izinga lokukhutshwa kunye neminye imiba, kwaye ufake imimandla yesicelo semveli yezinye iindidi ze-iron phosphate. iibhetri ze-lithium-ion.
