Abstract
In order to improve the charge-discharge energy density of a lithium secondary cell with a nonaqueous electrolyte having such a construction that a metallic compound capable of occluding or releasing lithium is used as an electrode active material, lithium or a lithium alloy is used as a negative electrode material and a solution of a lithium salt is used as an electrolyte, the microstructure of the metallic compound is rendered acicular. Further, a lithium-containing metallic compound grown into such a columnar form that has the angle .THETA. to the normal of the surface of the substrate of 0.degree..ltoreq..THETA.<90.degree. is used as the electrode active material.
