A lithium ion manganese oxide battery (LMO) is a that uses ( MnO 2), as the material. They function through the same /de-intercalation mechanism as other commercialized technologies, such as ( LiCoO 2). Cathodes based on manganese-oxide components are earth-abundant, inexpensive, non-toxic, and provide better thermal stability.
