POLYMER ELECTROLYTE AND LITHIUM POLYMER BATTERY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a single ion transmission type polymer alloy gel electrolyte that transmits only a lithium ion and provide a lithium polymer battery with its great discharge capacity, free of polarization by using the same. SOLUTION: A polymer alloy film solved with a solution-retardant polymer and a poly anion polymer in an organic electrolyte is prepared, and the organic electrolyte is impregnated and gelled. This polymer alloy gel has high mechanical strength and ion transmission and functions as a single ion transmitter. Polarization can be restricted by employing this single ion transmission type polymer alloy gel electrolyte and constituting a lithium polymer battery, and a discharge capacity greater than a battery employing a bi-ion transmission type polymer alloy gel can be obtained.
