Lithium Aluminum Manganese Oxide Having Spinel-Framework Structure for Long-Life Lithium-Ion Batteries

Abstract
Lithium aluminum manganese oxide (LAMO) having a spinel-framework structure was prepared and examined in lithium nonaqueous cells. LAMO shows extremely small irreversible capacity with rechargeable capacity of ca. in lithium cells operated in voltage of 3 to . To show durability for long-life applications, a lithium-ion cell of and LAMO was fabricated and accelerated cycle tests were done at room temperature in voltage of 2 to for 3600 cycles, and an empirical relation between capacity and number of cycle was obtained to be .
