Ngelixa ukudumba okuphakathi kunokuthi kwenzeke ngokwendalo kubomi bebhetri, ukudumba okubonakalayo kubonisa ukuba ibhetri kufuneka itshintshwe ngoko nangoko njengoko ubungozi bokusetyenziswa okuqhubekayo bugqabhuka okanye umlilo.

Nobunye ubuchwepheshe bugqwesileyo jikelele{0}}nganye iyagqwesa kwizicelo ezahlukeneyo. Iibhetri ze-LiPo zibonelela ngezinto eziluncedo kwizinto ezicekethekileyo, ezikhaphukhaphu, kunye neziqhelekileyo{2}}ezimilise okwee-smartphones kunye nee-drones. Iibhetri zeLithium-zibonelele ngeendleko ezingcono{5}}ukusebenza kakuhle, ubomi bomjikelo obude, kunye nomthamo ophezulu kwizinto ezisemgangathweni. Iimfuno zesicelo zimisela ukhetho olufanelekileyo.

Iibhetri ze-lithium zepolymer zibonisa ukuguquka okubalulekileyo kugcino lwamandla aphathwayo, ukulinganisa ukusebenza, ukuguquguquka, kunye nokuqwalaselwa kokhuseleko. Ukukwazi kwabo ukuhambelana noyilo lweemveliso ezahlukeneyo ngelixa behambisa amandla aphezulu okuxinanisa kubenze babaluleke kakhulu kwizinto zombane zala maxesha, ukusuka epokothweni -kubukhulu obunxitywayo ukuya kwizithuthi ezibhabhayo. Ukuqonda zombini izakhono zabo kunye nokusikelwa umda kwenza izigqibo ezinolwazi malunga nokuba itekhnoloji yepolymer ibonelela nini izibonelelo zokwenyani ngaphezulu kweebhetri zelithium zemveli. Njengoko isayensi yezixhobo iqhubela phambili kunye nezikali zokuvelisa, iibhetri ze-lithium zepolymer ziya kuqhubeka zisanda zibe kwizicelo ezitsha apho iimpawu zazo ezizodwa zivula uyilo lwemveliso entsha ebingenakwenzeka ngaphambili ngetekhnoloji yebhetri eqhelekileyo.
