<P>PROBLEM TO BE SOLVED: To provide a gelatinous electrolyte battery capable of significantly increasing energy density. <P>SOLUTION: The battery includes: a positive electrode and a negative electrode each including a material capable of storing and releasing lithium ions as a positive electrode active material or a negative electrode active material; a separator comprising a porous polyolefin film; and a gelatinous nonaqueous electrolyte; and is structured such that the gelatinous nonaqueous electrolyte containing a matrix polymer, a nonaqueous solvent and an electrolyte salt is arranged between the positive electrode and the separator and not arranged between the negative electrode and the separator. The distance between the positive electrode electrode side and the separator is set to 0 to 20 μm. The positive electrode active material is a lithium transition metal composite oxide, and the negative electrode active material is a carbon material, lithium or a lithium alloy. <P>COPYRIGHT: (C)2007,JPO&INPIT |
