Ukushaja ngokweqile amaseli ebhethri e-lithium{0}}angaphezu kuka-4.2V azoqala ukukhiqiza imiphumela engemihle. Uma iphezulu i-voltage yokushajwa ngokweqile, ingozi inkulu. Lapho i-voltage idlula i-4.2V, ngaphansi kwengxenye yama-athomu e-lithium asala entweni ye-electrode eqondile. Kuleli qophelo, amaseli okugcina avame ukuwa, okubangela ukulahlekelwa umthamo unomphela. Uma ukushaja kuqhubeka, njengoba amaseli okugcina ama-electrode angemahle asevele egcwele ama-athomu e-lithium, insimbi elandelayo ye-lithium izonqwabelana phezu kwezinto ezingezinhle ze-electrode. Lawa ma-athomu e-lithium azokhula abe amakristalu e-dendritic asuka endaweni eyi-electrode engemihle lapho kuvela khona ama-ion e-lithium. Lawa makristalu ensimbi e-lithium angangena kusihlukanisi, abangele umjikelezo omfushane phakathi kwama-electrode amahle nabi. Ngezinye izikhathi ibhethri liqhuma ngaphambi kokuba isifunda esifushane senzeke ngenxa yokuthi ngesikhathi sokushaja ngokweqile, i-electrolyte nezinye izinto ziyabola, zikhiqize igesi eyenza i-casing yebhethri noma i-valve yokucindezela iqhume futhi iqhume, okuvumela umoya-mpilo ukuba ungene futhi usabele ngama-athomu e-lithium aqoqwe endaweni engalungile ye-electrode, okuholela ekuqhumeni.
Ngakho-ke, lapho ushaja amabhethri e-lithium-ion, kubalulekile ukusetha umkhawulo wevolthi ephezulu ukuze ubhalansise impilo yebhethri, umthamo, nokuphepha. Umkhawulo ofanelekile wamandla kagesi wokushaja ngu-4.2V. Amaseli ebhethri ye-Lithium-ion nawo anomkhawulo we-voltage ophansi ngesikhathi sokuphuma. Lapho i-voltage yeseli yehla ngaphansi kuka-2.4V, ezinye izinto ziqala ukuwohloka. Ngaphezu kwalokho, ngenxa yokuthi amabhethri azikhipha{8}, amandla ogesi ayehla uma ephuma isikhathi eside; ngakho-ke, kungcono ukuthi ungachithi ku-2.4V ngaphambi kokuma. Phakathi nenqubo yokukhipha kusukela ku-3.0V ukuya ku-2.4V, amandla akhishwa ibhethri ye-lithium{13}}ion ahlanganisa kuphela cishe u-3% womthamo wawo. Ngakho-ke, i-3.0V iyi-voltage efanelekile yokukhipha ukukhishwa. Ngaphandle kwemikhawulo kagesi, ukulinganiselwa kwamanje kuyadingeka ngesikhathi sokushaja nokukhipha. Uma i-current iphezulu kakhulu, i-lithium ion ngeke ibe nesikhathi esanele sokungena kumaseli okugcina futhi izoqoqana endaweni ebonakalayo.
