Document Type and Number:
Japanese Patent JP2002313425
Kind Code:
A
Abstract:
To provide a highly reliable lithium polymer secondary battery capable of improving initial characteristics, cycle characteristics, and load characteristics, providing electrolyte replenishing capability, and eliminating fluid leakage.
This lithium polymer secondary battery comprises a porous negative electrode formed, as active material, of carbon material obtained by adhering amorphous carbon on the surface of graphite particles, an electrolyte layer, and a porous positive electrode formed, as active material, of a metal oxide containing lithium. The electrolyte layer comprises a cross-linked body containing a vinylene carbonate, an organic solvent, and a lithium salt.
