Ingemuva

Ubuchwepheshe bokushabalalisa ukushisa kwebhethri, obubizwa nangokuthi ubuchwepheshe bokupholisa, empeleni kuyinqubo yokushintshanisa ukushisa eyehlisa izinga lokushisa langaphakathi lebhethri ngokudlulisela ukushisa kusuka kubhethri kuya endaweni yangaphandle ngokusebenzisa indawo yokupholisa. okwamanje isetshenziswa ngezinga elikhulu kumabhethri okudonsa. , kanye namabhethri okugcina amandla, ikakhulukazi lawo esitsha se-ESS. Amabhethri e-Li-ion azwela kakhulu kuzinga lokushisa njengama-catalysts amakhemikhali ekusetshenzisweni kwangempela. Ngakho-ke inhloso yokukhipha ukushisa ukuhlinzeka ngezinga lokushisa elifanele lebhethri.Uma izinga lokushisa lebhethri le-Li-ion liphezulu kakhulu, uchungechunge lokusabela okuseceleni okufana nokubola kwefilimu eqinile ye-electrolyte interface (ifilimu ye-SEI) kuzokwenzeka ngaphakathi kwebhethri, okuthinta kakhulu impilo yebhethri.umjikelezo. Kodwa-ke, lapho izinga lokushisa liphansi kakhulu, ukusebenza kwebhethri kuzoguga ngokushesha futhi kube nobungozi bemvula ye-lithium,okuyintokuholela ekunciphiseni ngokushesha umthamo wokukhipha kanye nokusebenza okulinganiselwe ezindaweni ezibandayo. Ini'Ngaphezu kwalokho, umehluko wezinga lokushisa phakathi kweseli elilodwa kumojuli futhi uyisici okungafanele sizitshwe. Umehluko wezinga lokushisangaleububanzi obuthile buzoholela ekushajweni kwangaphakathi okungalingani kanye nokukhipha, okuholela ekuphambukeni komthamo. Ukwengeza, umehluko wezinga lokushisa uzophinde uholele ekwenyukeni kwezinga lokukhiqiza ukushisa kwamaseli eduze nendawo yokulayisha, okuholela ekuhlulekeni kwebhethri.

Njengamanje, ngokusho kwendawo yokudlulisa ukushisa, kunezinhlelo zokukhipha ukushisa ezivuthiwe ezifanaumoya opholileing, uketshezi-okupholileing, kanye nokupholisa impahla yokushintsha kwesigaba.

Umoya kupholileingubuchwepheshe

Ubuchwepheshe bokupholisa umoya buyindlela esetshenziswa kakhulu yokupholisa ibhethri.

Kweminye imikhiqizo yezinga eliphakathi nendawo eliphezulu, ngenxa yokushaja okuphezulu nokukhipha amandla, ukushisa ngaphakathi kwemojula akukwazi ukuchithwa ngokushesha nangempumelelo ngokupholisa kwemvelo kuphela, njengoba kuzokwenza kalula ukuqoqwa kokushisa ngaphakathi futhi kuthinte impilo yomjikelezo wamaseli. . Ngakho-ke, indlela yokupholisa umoya ephoqelelwe ifaneleka kakhulu esimweni sokusetshenziswa kwemikhiqizo yokugcina amandla esezingeni eliphakathi neliphezulu.

Ubuchwepheshe bokupholisa uketshezi

Inzuzo yobuchwepheshe bokupholisa uketshezi ukuthi umthamo wokushisa othize kanye ne-thermal conductivity yendawo yokudlulisa ukushisa kuphakeme, okungaxazulula kangcono ukuphathwa okushisayo kwesistimu yebhethri kunokupholisa okupholile emoyeni. Njengamanje, kunezinhlobo ezimbili zamasistimu okupholisa uketshezi: ukuthintana okuqondile kanye nokuthintana okungaqondile, okusekelwe ekutheni isipholisi singathintana ngqo nebhethri.

Isistimu yokupholisa uketshezi oluthinta ngqo

Isistimu yokupholisa uketshezi olungaqondile

Ukupholisa uketshezi kunomphumela ongcono wokulahla ukushisa kunokupholisa komoya, futhi inqubo yokushintshanisa ukushisa iqonde kakhulu, isebenza kahle futhi ivaliwe. Kodwa-ke, ukupholisa uketshezi kudinga ukusebenza kokuvala okuphezulu kwesakhiwo kanye nezindleko eziphezulu zokukhiqiza. Ukuthuthukisa okokusebenza kwepuleti lokupholisa, indawo yepuleti lokupholisa, ukukhetha isipholisa, ukuma kwepayipi, ifomu lokuhlelwa kwamapayipi nokuthandwa kungathuthukisa ukusebenza kokukhipha ukushisa. Ubuchwepheshe bokupholisa uketshezi buzoba isiqondiso esiyinhloko sokuthuthukiswa kobuchwepheshe bokupholisa besikhathi esizayo bebhethri yokugcina amandla.

Isigabaclengami-aterialtubuchwepheshe

Ukupholisa komoya kanye nokupholisa uketshezi ikakhulukazi kuncike emandleni angaphandle ukushayela, kuyilapho ukupholisa okubalulekile kokushintsha kwesigaba kuyindlela engenzi lutho yokulawula izinga lokushisa, elifanele ezinye izimo ezinezidingo eziphezulu zokunqanyulwa kokushisa kodwa indawo ezungezile elinganiselwe.

Isiphetho

Ucwaningo lobuchwepheshe bokupholisa ibhethri luyisihloko esiyinkimbinkimbi, ngaphezu kokuhlangabezana nezici zomphumela omuhle kakhulu wokupholisa, ukwakheka okuhlangene, ukuphepha okuphezulu nokusebenza kwendawo yonke, kodwa futhi kudingeka kucatshangelwe izidingo zomnotho. Ikakhulukazi, imakethe yamanje yokugcina amandla iyadlondlobala, ibhethri yokugcina amandla esiqukathi, uma kuqhathaniswa namanye amabhethri, inezinga eliphezulu, eliminyene lokuhlelwa kwebhethri. Esikhaleni esivalekile, inezimo zokusebenza nemvelo eyinkimbinkimbi futhi enokhahlo, futhi idinga nokusebenza ngaphandle kokuphazamiseka. Ikakhulukazi kulabo abanokuhamba kwesistimu yokugcina amandla esiqukathi, edinga ukuzivumelanisa nesimo sangaphandle esinzima kakhulu, ngakho-ke ibhethri elisetshenziswa ohlelweni lokugcina amandla esiqukathi linezidingo eziphezulu zokuvumelana nezimo endaweni yangaphakathi nengaphandle. Ngokuzayo sidinga ubuchwepheshe bokupholisa ibhethri obusebenza kahle kakhulu, obuzinzile, obuyonga kakhulu, obuhlangene kakhulu.
