Betri ea lithium-ion e sebetsa joang? E na le melemo efe ho feta betri ea asiti ea lead? Polokelo ea betri ea lithium-ion e lefa neng?A betri ea lithium-ion(e khuts'oane: betri ea lithiumion kapa betri ea Li-ion) ke lentsoe le tloaelehileng bakeng sa li-accumulators tse thehiloeng ho metsoako ea lithium ka mekhahlelo eohle e meraro, ka electrode e mpe, ho electrode e ntle hammoho le electrolyte, sele ea electrochemical. Betri ea lithium-ion e na le matla a khethehileng ha e bapisoa le mefuta e meng ea libeteri, empa e hloka li-circuits tsa ts'ireletso ea elektroniki lits'ebetsong tse ngata, kaha li arabela hampe ho tsoa ho tebileng le ho tjhaja ho feta tekano.Libetri tsa letsatsi tsa lithium ion li qosoa ka motlakase ho tloha tsamaisong ea photovoltaic ebe li lokolloa hape ha ho hlokahala. Ka nako e telele, libeteri tse etellang pele li ne li nkoa e le tharollo e loketseng ea matla a letsatsi bakeng sa morero ona.
