TEMPERATURE EFFECTS ON LITHIUM INTERCALATION INTO CARBONIZED CLOTH

The rate of lithium corrosion from intercalated carbon electrodes is m easured for different intercalation degrees in various electrolytes at temperatures ranging from -35 to 45 degrees C. The corrosion kinetics is shown to hardly depend on the electrolyte nature and intercalation degree. Corrosion is assumed to be limited precisely by the rate of t he cathodic electrolyte reduction. The temperature coefficient for the equilibrium potential of intercalate is determined in 1 M LiClO4 in p ropylene carbonate and dimethoxyethane mixture solutions. The kinetics of lithium intercalation (and deintercalation) into carbonized cloth is studied at -35 to 45 degrees C.
