This product is a silicon-carbon composite anode material developed for advanced lithium-ion battery research, featuring a porous carbon skeleton deposited with silicon. Designed for experimental and energy material applications, it requires vacuum-sealed storage to maintain stability. During electrochemical testing, the manufacturer recommends using a dedicated silicon-carbon electrolyte (KLD-Si01) and baking the electrode at 85 °C for 4 hours. The material’s porous architecture supports high silicon loading and accommodates volume changes during cycling, making it suitable for half-cell evaluations and anode performance studies. With multiple batch sizes available, it serves as a consistent reference for researchers investigating high-capacity anode systems.
