Inani lemijikelo yeLiFePo4 ibhetri yelangakunye nobomi benkonzo phakathi kweebhetri zidibaniswe ngokungenakuhluthwa. Umthamo webhetri uya kuncipha kancinci ngalo lonke ixesha umjikelo ugqityiwe, kwaye ubomi benkonzo ye-lifepo4 ibhetri yelanga nayo buya kuncipha. Ke ubude bomjikelo welifepo4 ibhetri yelanga? Kweli nqaku, ibhetri ye-BSLBATT iya kuthetha nawe malunga nobomi bebhetri. Bude kangakanani ubomi bomjikelezo weLiFePo4 iibhetri zelanga? Kukho iindlela ezininzi zokugcina amandla, kwaye iibhetri ze-lead-asidi yenye yazo, kodwa ukuba sijonga kwiindawo ezithile, ixesha lifikile lokuba iibhetri ze-lithium zithathe indawo yeebhetri ze-lead-acid. Kutheni kunjalo? Isizathu esona sikhulu kukuba ibhetri yelanga ye-lifepo4 inobomi bomjikelo obude kunebhetri eneasidi ekhokelela kwaye ayifuni kugcinwa. Ubomi bomjikelo bubhekisa kumaxesha amangaphi ibhetri inokumelana nokutshaja nokukhupha phambi kokuba umthamo webhetri wehle ukuya kwixabiso elithile phantsi kwenkqubo ethile yokutshaja nokukhupha. Ubomi bomjikelezo webhetri yelanga ye-LiFePo4 imele inani lemijikelo enokuthi ihlawulwe kwaye ikhutshwe ngaphambi kokuba umthamo webhetri wehle ukuya kwinqanaba elithile. Ngokutsho kwedatha, ibhetri yelanga yeLiFePo4 ngokubanzi ifezekisa ubomi bomjikelezo wamaxesha angaphezu kwama-5000. Iibhetri yelanga lithiumesetyenziswa kwintsimi yokugcina amandla ngokubanzi ifuna imijikelezo engaphezu kwe-3,500, oko kukuthi, ixesha lokuphila kwebhetri ye-lithium yokugcina amandla ingaphezulu kweminyaka eyi-10. Inombolo yomjikelo webhethri yelanga ye-LiFePo4 iphezulu kakhulu kunebhetri ye-lead-acid kunye nebhetri ye-ternary, kwaye inombolo yomjikelezo inokufikelela ngaphezu kwamaxesha e-7000. 
Nangona ixabiso lokuthengwa kwebhetri yelanga ye-LiFePo4 iphindwe kabini ukuya kathathu kwiibhetri ze-lead-acid, inzuzo yezoqoqosho yexesha elide iphezulu kakhulu. Ngamanye amazwi, ukuba ubomi bomjikelezo webhetri yelanga ye-LiFePo4 bude ngokwaneleyo, nokuba ixabiso lokuqala lokuthenga liphezulu kancinci, ixabiso elipheleleyo lisabiza. Ngapha koko, umgangatho webhetri yelanga yeLiFePo4 ikakhulu ixhomekeke kwizinto zayo. Ngokuqhelekileyo, ibhetri yelanga ye-LiFePo4 enomgangatho obalaseleyo inobomi obude, obunokunciphisa ngokufanelekileyo iindleko zokulungiswa nokugcinwa, kunye nokunciphisa utyalo-mali olupheleleyo lwenkqubo. Ubala njani ubomi bebhetri yelanga yeLiFePo4? Umgangatho wesizwe uchaza iimeko zomjikelo wovavanyo lobomi kunye neemfuno zeebhetri ze-lithium-ion: intlawulo yemizuzu eyi-150 phantsi kwemowudi eqhubekayo yangoku kunye ne-voltage engaguqukiyo ye-1C inkqubo yokutshaja kwiqondo lobushushu le-25 degrees, kunye nokukhupha phantsi kwenkqubo yokukhutshwa kwe-1C rhoqo ngoku. 2.75V njengomjikelo. Uvavanyo luphela xa ixesha lokukhupha elinye lingaphantsi kwemizuzu engama-36, kwaye inani lemijikelo kufuneka libe likhulu kune-300. Ngapha koko, inani lemijikelo ye-lifepo4 ibhetri yelanga ayichatshazelwa kuphela yindlela abasebenzisi abayisebenzisa ngayo, kodwa inxulumene nenqanaba letekhnoloji yemveliso kunye nefomyula yezinto.umenzi webhetri ye-lithium-ion. Ngaba amaxesha omjikelezo kunye nobomi benkonzo yeLiFePo4 ibhetri yelanga iyachaphazela omnye nomnye? Ngaba amaxesha omjikelezo kunye nobomi benkonzo yeLiFePo4 ibhetri yelanga iyachaphazela omnye nomnye? Kwibhetri yelanga yeLiFePo4, kukho amaxesha amabini okuphila ngokubanzi: ubomi bomjikelezo kunye nobomi bokugcina. Okukhona imijikelo emininzi okanye ixesha elide lokugcina, kokukhona ukulahleka kobomi bebhetri yelanga yeLiFePo4. Nangona kunjalo, ubomi bebhetri ye-LiFePo4 bude kuneebhetri ze-asidi zemveli. Iibhetri ze-LiFePo4 eziveliswa ngabavelisi bebhetri ye-lithium abaqhelekileyo banemijikelezo engaphezu kwama-2500. Umjikelo uyasetyenziswa. Sisebenzisa iibhetri kwaye sixhalabile malunga nexesha lokusetyenziswa. Ukuze kulinganiswe ukusebenza kokuba ibhetri etshajwayo ingasetyenziswa ixesha elingakanani, inkcazo yenani lemijikelo ichaziwe. Isizathu sokuba i-LiFePo4 ibhetri yelanga inokutshintsha ezinye iintlobo zeebhetri zemveli zikwanxulumene nobomi bayo obude benkonzo. Kwindawo yebhetri, ukulinganisa ubomi benkonzo yebhetri ngokuqhelekileyo akubonakali nje ngexesha, kodwa ngenani lamaxesha okutshaja nokukhupha. Ngokobomi benkonzo ye-ternary lithium ibhetri okanye i-lithium iron phosphate ibhetri, ubomi benkonzo yebhetri bumalunga ne-1200 ukuya kwi-2000 imijikelezo, kunye nenani lomjikelo weebhetri ze-lithium iron phosphate malunga ne-2500. Inani lemijikelezo liya kuncipha njengoko ibhetri isetyenziswa, kwaye inani lemijikelezo liya kuncipha, oku kuthetha ukuba ubomi benkonzo ye-LiFePo4 ibhetri yelanga nayo iyancipha ngokuqhubekayo. Ngexesha lokusetyenziswa, inani lemijikelo yebhetri Ukuncipha okuqhubekayo kuthetha ukuba i-electrochemical reaction engenakuguqulwa iya kwenzeka ngaphakathi kwebhetri ye-LiFePo4, okubangela ukuhla kwamandla. Inombolo yomjikelo wobomi bebhetri yelanga yeLiFePo4 imiselwe ngokomgangatho webhetri kunye nezinto zebhetri. Inombolo yomjikelo we-LiFePo4 ibhetri yelanga kunye nobomi benkonzo phakathi kweebhetri zidibaniswe ngokungenakuqhathaniswa. Ngalo lonke ixesha umjikelezo ugqityiwe, amandla ebhetri yelanga yeLiFePo4 aya kuncitshiswa kancinane, kwaye ubomi benkonzo yebhetri yelanga yeLiFePo4 buya kuncitshiswa. Oku kungasentla yinkcazo yobomi bomjikelo weLiFePo4 ibhetri yelanga. Njengoko ixesha lokusetyenziswa lisanda, ubomi bebhetri yelanga ye-lithium buya kuchaphazeleka. Ngokuqhelekileyo, ibhetri yelanga ye-lithium isetyenziswe ngokufanelekileyo kwaye indlela echanekileyo isetyenziselwa ukwenza ubomi bebhetri ye-lithium ubude.
