Kemgbe mmepụta nke batrị lithium-ion na 1991, graphite bụ ihe na-adịghị mma maka batrị.Lithium titanate, dị ka ụdị ọhụrụ electrode ihe na-adịghị mma maka batrị lithium-ion, nwetara nlebara anya na njedebe 1990s n'ihi arụmọrụ ya dị mma.Dịka ọmụmaatụ, ihe ndị dị na lithium titanate nwere ike ịnọgide na-enwe nkwụsi ike dị elu na nhazi kristal ha n'oge ntinye na mwepụ nke ion lithium, na obere mgbanwe na nkwụsị nke lattice (mgbanwe olu.
Ihe elektrọd a “ndụ efu” na-agbatị ndụ okirikiri nke batrị lithium titanate nke ukwuu.Lithium titanate nwere ọwa mgbasa lithium ion pụrụ iche nwere akụkụ atọ nwere usoro spinel, nke nwere uru dị ka njirimara ike dị mma yana arụmọrụ dị elu na nke dị ala.E jiri ya tụnyere carbon electrode ihe na-adịghị mma, lithium titanate nwere ikike dị elu (1.55V dị elu karịa lithium dara), nke na-eme ka oyi akwa siri ike na-etolite n'elu electrolyte na carbon electrode adịghị etolite n'elu lithium titanate. .
