Title:
LITHIUM BATTERY COMPRISING A GEL-ELETROLYTE
Document Type and Number:
WIPO Patent Application WO2001035471
Kind Code:
A3
Abstract:
A lithium battery, comprising a negative electrode, a positive electrode, a separator, and a non-aqueous electrolyte solution between the negative and the positive electrode. At least the negative electrode material and the positive electrode material are provided with a pattern of holes which accommodate a polymeric material which sticks and presses the negative electrode, the positive electrode and the separator together. In order to decrease the tendency of the electrolyte solution to sublime, thereby expanding the packaging material around the battery, the non-aqueous electrolyte solution comprises a solution of lithium salts, solvent molecules and a polymer, forming a gel-electrolyte.
