Abstract
SOLID-STATE BATTERIES HAVE LONGER SHELF-LIFE AND BETTER RELIABILITY THAN THEIR LIQUID ELECTROLYTE COUNTERPARTS. THEY HAVE LONG SHELF-LIFE DUE TO LITTLE OR NO SELF-DISCHARGE, ARE RUGGED AND CAN BE ASSEMBLED INTO LEAKAGE CURRENT-FREE BIPOLAR STRUCTURES. BIPOLAR BATTERIES ARE DESIRED FOR APPLICATIONS REQUIRING HIGH POWER DRAINS SUCH AS PORTABLE COMMUNICATION EQUIPMENT, ELECTRIC DRILLS, ENGINE STARTERS, AND SPACE-BASED PULSE POWER SOURCES. THE BASIC CELL UNIT OF THE BATTERY BEING DEVELOPED CAN BE REPRESENTED AS: LI INSERTION ANODE/SOLID POLYMER ELECTROLYTE/LI INSERTION CATHODE. ITS DEVELOPMENT IS MADE POSSIBLE BY THE LI+ CONDUCTIVE SOLID POLYMER ELECTROLYTES WITH CONDUCTIVITIES OF 2X10E-3 OHME-1 .CME-1 AT 25 DEGREES CELSIUS, RECENTLY DISCOVERED AT EIC. THE ABSENCE OF ELEMENTAL LI MAKES THE BATTERY HIGHLY SAFE WHILE THE "LI ION" CONCEPT ENSURES HIGH ENERGY DENSITY. THE SINGLE CELL VOLTAGE IS V. THE THEORETICAL SPECIFIC ENERGY OF A SINGLE CELL IS 474 WH/KG. PRACTICAL BATTERIES WILL SHOW A POWER CAPABILITY AS HIGH AS 100 KW/KG AND A SPECIFIC ENERGY AS LARGE AS 100 WH/KG.
