A High-Rate Manganese Oxide for Rechargeable Lithium Battery Applications

“…Work is underway in several groups to improve the metastability by admetal doping or by pillaring the layers. 9 Alternatively, layered compounds that do not have cubic close packed arrays of oxygen may prove to be more resistant to spinel conversion but can undergo other irreversible phase transitions during the first few cycles. 10 Layered oxides and most tunnel-type oxides are incapable of accommodating the tetragonal Jahn-Teller distortion that occurs on reduction of Mn͑IV͒ to Mn͑III͒.…”
