AI Technical Summary
Existing silicon-carbon anode materials cannot meet the fast-charging requirements in the electric vehicle field, mainly due to their poor charge transport capabilities, which limits the development of lithium batteries in fast-charging applications.
A method for preparing silicon-carbon anode materials using lignin composites involves treating a mixed solution of phenolic resin, lignin, and a co-solvent, combined with plasma treatment and activation pore-forming technology, to form a stable porous carbon structure, thereby improving electronic conductivity and lithium-ion transport capacity.
The lithium battery anode material achieves high initial efficiency, long cycle life, and high rate performance, improving the battery's charge and discharge efficiency and cycle stability, and meeting the fast charging requirements of electric vehicles.
