Abstract
The present invention relates to a method for preparing a lithium manganese oxide-based material useful in applications such as for pseudocapacitors and lithium ions batteries. More specifically, by synthesizing manganese oxide nanoparticles and mixing them with lithium salts, and conducting stepwise heat treatment processes under optimized conditions, a lithium manganese oxide-based material with excellent specific capacitance, having a high surface area with a small size, can be prepared.
