Abstract
Disclosed is an electrical storage device having excellent safety and high battery capacity. Specifically disclosed is an electrical storage device comprising at least a positive electrode having a positive electrode active material layer and a positive electrode collector, a negative electrode having a negative electrode active material layer and a negative electrode collector, a separator and an organic electrolyte solution. This electrical storage device is characterized in that the negative electrode active material layer is composed of a metal complex oxide which absorbs and desorbs lithium ions, the positive electrode active material layer contains a carbonaceous material having a layered crystal structure, and the interlayer distance d002 of the layered crystal structure in the carbonaceous material is within the range of 0.36-0.38 nm.
