Title:
LITHIUM SECONDARY BATTERY AND ITS MANUFACTURE
Document Type and Number:
Japanese Patent JP2000294288
Kind Code:
A
Abstract:

To provide a newly structured lithium secondary battery improved so that a dendrite can be completely prevented from being deposited, alignment is facilitated when stacked and battery cells can be excellently packaged for instance.

In this lithium secondary battery, a positive electrode and/or a negative electrode is composed of at least a collector and an active material layer adhered onto it by a polymer while holding an electrolyte, the polymer is induced from a gel forming monomer, and the positive electrode and the negative electrode are flatly stacked with intervention of an electrolyte layer formed by the electrolyte held by the polymer induced from the gel forming monomer. The collectors on the positive electrode side and on the negative electrode side have the almost same sizes, an insulating spacer is disposed on the peripheral rim part of the positive collector and the active material is formed inside the insulating spacer.
