Ingcebiso Ukuthintela ukusilela kwebhetri yefowuni ephathwayo Iingcebiso zokuthintela ukungaphumeleli kwebhetri yefowuni ephathwayo Ubuncinci, ukhuseleko lweebhetri ze-lithium zepolymer lubonakala luphezulu kakhulu, olufana neemeko zokuvutha komlilo ngokubanzi kunzima ukugqobhoza. Nangona kunjalo, sinokuqonda kwakhona kwiingxelo zeendaba ngamaxesha athile, imililo yebhetri, abantu baziva besoyika. Kule nkalo, iYunivesithi yaseNanjing yeSayensi kunye neTekhnoloji yeKhemistry yeLebhu iqhube uvavanyo lokwenyani lokhuseleko lokutshaja ibhetri, kwaye kufuneka iphendule abantu kwinqanaba elithile.

Abaqhubi beLabhoratri baya kuthatha inxaxheba kwiisimboli ezimbini zebhetri ye-lithium-ion, enye yeebhetri eziqhelekileyo, enye ibhetri yokulondoloza umonakalo wesiphaluka. Emva kweeyure ezingaphezu kwe-12 zokutshaja, ibhetri eqhelekileyo ayinayo nayiphi na into engaqhelekanga, ngelixa ibhetri eyonakalisiweyo yonakaliswe emva kokuba izinga lokushisa likhuphuke kwi-100 degrees. Ngamanye amaxesha, ibhetri yeselula iya kuqhuma xa ihlawulisa ibhetri ye-lithium-ion, kuya kubakho isiphaluka sokugcinwa ukukhusela ukuthintela umonakalo we-lithium-ion ibhetri yoxinzelelo, ukugqithisa, njl njl.

Xa ibhetri iphuphuma, inkqubo yokugcina iya kuchongwa ngokuzenzekelayo, itshintshe ukusuka kumbane omkhulu ukuya kwincinci yangoku, ngoko ifowuni yeselula ayiyi kuhlawuliswa. Ngoko ke, ukuba ibhetri ye-lithium ion ayiphumelelanga kwishaja kunye nokugcinwa kwesekethe, nokuba ukutshaja kwetanki akwenziwanga, ayenzi umonakalo kwisakhiwo sebhetri, kwaye ayibangeli ukuba ibhetri iqhume umlilo. Ngokutsho kumajelo eendaba ingxelo ifowuni ephathwayo ibhetri iyaqhubeka kubangela iimeko ukuqhushumba inokuba ngenxa yesekethe yokugcina umonakalo, kunokuqwalaselwa ukuba ibhetri iphantsi kwamandla angaphandle, okanye kukho ubushushu obuphezulu kunye nokufuma okunxulumene namava anxulumene namava.

Ukutshaja kwefowuni yeselula kufuneka kuthathelwe ingqalelo kwizinto ezimbalwa. Ukongezelela, nangona ukhuseleko lweebhetri ze-lithium ion ze-polymer ziphezulu kunoko kwibhetri ye-lithium ion, qaphela amanqaku ambalwa ekusebenziseni imihla ngemihla. Okokuqala, ukuqinisekisa ukusetyenziswa kwebhetri yokuqala kunye neshaja, ngokuqinisekileyo, imveliso edibeneyo yokucwangcisa umzimba ayikho ingxaki.

Okwesibini kukuba ifowuni ephathwayo ayinako ukwesaba ukutshaja kwexesha elide, kodwa ubeke ingqalelo kwimeko yefowuni yeselula, ukutshatyalaliswa kobushushu kufuneka kube ngcono, umzekelo, iifowuni eziphathwayo zinokuba phantsi komqamelo, oyingozi kakhulu. Okwesithathu, xa ibhetri yeselula ine-edema, kufuneka uyeke ukuyisebenzisa ngokukhawuleza. Ungayibuyisela kwangoko ibhetri.

Musa ukuyivula ibhetri ukwenza inkqubo eqhelekileyo emva kokuthengisa, musa ukuqhubeka nokusebenzisa kungenjalo kunokwenzeka ukuba kwenzeke. Ukususela kwiibhetri zokuqala ze-nickel-hydrogen ukuya kwiibhetri ze-lithium-ion zanamhlanje kunye neebhetri ze-lithium polymer, iibhetri zeselula ziphuculwe ngokubanzi. Ngokuqhelekileyo, ukuba nje ukugcinwa kufanelekileyo, iibhetri zefowuni zinzima ukubangela ukutshiswa kokhuseleko lomntu okanye ukuqhuma, abathengi abanakukhathazeka kakhulu.
