Inventor: KOHAMA KEIICHI
IPC: H01M10/0565
Filed: 2001-07-09
Abstract: PROBLEM TO BE SOLVED: To reduce the internal resistance of a lithium secondary battery. SOLUTION: This lithium secondary battery 10 is constituted, arranging a separator 16 between a positive electrode 12 and a negative electrode 14, and arranging a gel electrolyte 17 inside membranes of the positive and negative electrodes. The separator 16 is gel electrolyte membrane having about 10 kg/cm<2> elastic modulus, and can keep the positive and negative electrodes in a non- contact state, even if both electrodes are made to face. Since the separator 16 has about 1 mS/cm ionic conductance and will not disturb the movement of lithium ions between the positive and negative electrodes. The gel electrolyte 17 has small coordination force with respect to lithium ions, and has interaction with the lithium ions which is smaller than the separator 16 that is the gel electrolyte membrane.  Therefore, the gel electrolyte 17 easily brings about the coordination of an electrolyte material, coordinated with the lithium ions on the electrode interface between the positive and negative electrodes, and the insertion/separation reaction of the lithium ions on the electrode interface is made to proceed smoothly.
