Ho tloha ha ho etsoa liindasteri tsa libeteri tsa lithium-ion ka 1991, graphite esale e le sesebelisoa se ka sehloohong sa li-electrode bakeng sa libeteri.Lithium titanate, e le mofuta o mocha oa lisebelisoa tsa elektrode tse mpe bakeng sa libeteri tsa lithium-ion, li ile tsa hlokomeloa ho elella bofelong ba lilemo tsa bo-1990 ka lebaka la ts'ebetso ea eona e ntle haholo.Ka mohlala, lisebelisoa tsa lithium titanate li ka boloka tekanyo e phahameng ea botsitso mohahong oa bona oa kristale nakong ea ho kenngoa le ho tlosoa ha lithium ion, ka liphetoho tse fokolang ho li-lattice constants (ho fetoha ha molumo).
Lintho tsena tsa "zero strain" tsa elektrode li eketsa haholo bophelo ba potoloho ea libeteri tsa lithium titanate.Lithium titanate e na le mocha o ikhethang oa lithium ion tse nang le likarolo tse tharo tse nang le sebopeho sa spinel, se nang le melemo e kang litšobotsi tse ntle tsa matla le ts'ebetso e babatsehang ea mocheso o phahameng le o tlaase.Ha ho bapisoa le lisebelisoa tsa carbon negative electrode, lithium titanate e na le matla a phahameng (1.55V e phahameng ho feta metallic lithium), e leng se etsang hore ho be le lera le tiileng la metsi le atisang ho hōla holim'a electrolyte le carbon negative electrode e sa thehoa holim'a lithium titanate. .
Habohlokoa le ho feta, ho thata hore lithium dendrites e thehoe holim'a lithium titanate ka har'a mefuta e mengata ea tšebeliso ea betri e tloaelehileng.Sena se felisa haholo monyetla oa lipotoloho tse khutšoane tse entsoeng ke lithium dendrites ka har'a betri.Kahoo polokeho ea libeteri tsa lithium-ion tse nang le lithium titanate e le electrode e mpe hona joale ke eona e phahameng ka ho fetisisa har'a mefuta eohle ea libeteri tsa lithium-ion tseo mongoli a li boneng.
Bongata ba indasteri ba utloile hore bophelo ba lithium betri cycle ea lithium titanate e nkang graphite ha thepa e mpe ea electrode e ka fihla makhetlo a mashome a likete, e phahame haholo ho feta libeteri tse tloaelehileng tsa lithium-ion, 'me e tla shoa ka mor'a lipotoloho tse likete tse' maloa feela. .
