Core Viewpoint - The company has developed a negative-free battery technology that eliminates the need for active materials in the anode during the battery manufacturing process, enhancing efficiency and performance [1] Group 1: Technology Overview - The negative-free technology operates by allowing lithium ions to move from the cathode to the surface of a current collector during charging, forming a metallic layer [1] - During discharging, this metallic layer dissolves back into the cathode, indicating a novel approach to battery design [1] Group 2: Material Innovation - The company has developed three-dimensional and porous copper foils that are essential for the application of the negative-free technology, as they provide the necessary lithium affinity [1]
