Ibhetri ye-LiFePo4 ibhekisa kwibhetri ye-lithium ion kunye ne-lithium iron phosphate njengento efanelekileyo ye-electrode kunye nekhabhoni njengento engafanelekanga ye-electrode.
Ibhetri ye-lithium ye-ternary ibhekisela kwibhetri ye-lithium esebenzisa i-nickel-cobalt-manganate lithium okanye i-nickel-cobalt-aluminate lithium njengento efanelekileyo ye-electrode kunye negraphite njengento engafanelekanga ye-electrode.Olu hlobo lwebhetri lubizwa ngokuba yi "ternary" kuba ityuwa yenickel, ityuwa yecobalt kunye netyuwa yemanganese zihlengahlengiswa ngokwemilinganiselo emithathu eyahlukileyo.
I-Shenzhen Meind Technology Co., Ltd isandula ukukhupha amandla aphathwayounikezelo lwamandla okugcinakunye eyakhelwe-ngaphakathi ternary lithium ibhetri, ebizwa ngokubaunikezelo lwamandla lwangaphandleokanyeisikhululo samandla esiphathwayo.Kodwa zininziimithombo yamandla yangaphandlekwimarike esebenzisa iibhetri zeLiFePo4.Kutheni sisebenzisa ibhetri ye-lithium ye-ternary?Ngenxa yokuba ibhetri ye-lithium ye-ternary nayo ineenzuzo (ngokulandelayo) kwiibhetri ze-LiFePo4.
1.Ukuxinana kwamandla
Ngokubanzi, ibhetri ye-lithium ye-ternary inokugcina amandla amaninzi kwiyunithi yomthamo okanye ubunzima, oku kubangelwa ukungafani kwezinto ze-electrode phakathi kwabo.Izinto ze-cathode ze-LiFePo4 ibhetri yi-lithium iron phosphate, kunye ne-ternary lithium ibhetri yi-nickel cobalt manganese okanye i-nickel cobalt aluminium.Umahluko kwiimpawu zeekhemikhali zenza ubuninzi bamandla ebhetri ye-lithium ye-ternary yobunzima obufanayo ngamaxesha e-1.7 yebhetri ye-LiFePo4.
2.Ukusebenza kobushushu obuphantsi
Ukusebenza kwebhetri ye-LiFePo4 kwiqondo eliphantsi lobushushu libi ngakumbi kunebhetri ye-lithium ye-ternary.Xa i-LiFePo4 ikwi--10 ℃, umthamo webhetri wehla ukuya malunga ne-50%, kwaye ibhetri ayikwazi ukusebenza ngaphaya -20 ℃ kakhulu.Umda osezantsi we-ternary lithium yi-30 ℃, kwaye iqondo lokuthomalalisa umthamo we-ternary lithium lingaphantsi kweLiFePo4 kwiqondo lobushushu elifanayo.
3.Ukutshaja ngokufanelekileyo
Ngokumalunga nokutshaja ngokufanelekileyo, ibhetri ye-lithium ye-ternary iyasebenza ngakumbi.Idatha yovavanyo ibonisa ukuba kukho umahluko omncinci phakathi kwebhetri ezimbini xa utshaja ngaphantsi kwe-10 ℃, kodwa umgama uya kutsalwa xa utshaja ngaphezulu kwe-10 ℃.Xa utshaja kwi-20 ℃, umlinganiselo okhoyo ngoku we-ternary lithium ibhetri yi-52.75%, kwaye ibhetri ye-LiFePo4 yi-10.08%.Owokuqala uphindwe kahlanu kowokugqibela.
