摘要： The present disclosure relates to a lithium titanium composite oxide including aluminum-coated primary particles and to a method for manufacturing the same.
A lithium titanium composite oxide including aluminum-coated primary particles according to an embodiment is manufactured as the primary particles are coated with aluminum by mixing an aluminum compound with particles re-pulverized after preparation of a lithium titanium oxide and then by spray-drying the mixture again to prepare secondary particles, and a battery including the lithium titanium composite oxide including the aluminum-coated primary particles according to an embodiment exhibits effects of suppressing electrolyte decomposition and gas generation that may be respectively caused by titanium ions and residual lithium in conventional lithium titanium composite oxides.
