CONDUCTIVE CARBON LAYERS ON POWDERED SUPPORTS

IP Title

Process for the preparation of conductive carbon layers on powdered supports

Summary

A process for the preparation of carbon layers on powdered supports comprising dissolving a hydrophilic polymer (PH) at the level of 85 do 99.9% by weight in water, adding pyromellitic acid (PMA) or pyromellitic dianhydride (PMDA) at the level of 0.1-15% by weight, then introducing to the mixture the powdered support at a level of 1-99% by weight. The suspension is concentrated and dried, and the composite precursor formed is subjected to a pyrolysis process at 300-1500 DEG C.

Technology Application

Lithium-ion (Li-Ion) batteries are devices for collecting and transmitting electricity with the highest energy storage capacity per weight and volume.Commonly they are used in cell phones, digital cameras and notebooks, but also in the measuring apparatus, electro-tools, telemetry systems, satellite communications, or in a hybrid-powered (HEV) and electric cars (EV). Battery negative electrode is made of porous carbon or graphite while positive electrode of transition metal oxides (cobalt,
