Latest Patents

Wakihara's latest patents include innovations in electrolytes for secondary batteries and cathodes formed of graphite/carbon composites for lithium-ion secondary batteries. His patented process involves mixing high crystallinity powdery graphite with an organic binder that forms low crystallinity carbon after firing. A high shearing force is applied to ensure that both components are well-dispersed through a mechano-chemical reaction. The resulting paste is extruded to achieve a highly oriented structure of graphite. The green extrudate is then fired in an inert atmosphere at temperatures between 500 and 1,100 degrees Celsius, carbonizing the organic binder and yielding a graphite-carbon composite suitable for use as a cathode in lithium-ion batteries.
