Abstract
Disclosed herein are a manganese carbonate useful as a material for spinel-type LiMn2O4, having a spherical morphology, and a method of preparing the same. The spheric manganese carbonate has a high packing density and shows superior lifetime characteristics, leading to spinel-type LiMn2O4 resistant to structural changes and having superior lifetime characteristics.
