Introduction of Lithium Silicon Alloy Powder
Lithium-silicon alloy powder is an alloy material composed of two elements, lithium (Li) and silicon (Si). Due to its high theoretical specific capacity (relative to traditional graphite-based anode materials), lithium-silicon alloy powder shows great potential in improving battery energy density.
Ingredients: Li: 44 Silicon Remainder
Particle size: 150 mesh
Lithium Silicon Alloy Powder for Thermal Battery Materials
Features of Lithium Silicon Alloy Powder
High specific capacity: Lithium-silicon alloy can theoretically store more lithium ions, thus providing higher energy density.
Lightweight: Both lithium and silicon are relatively light elements, making lithium-silicon alloy a lightweight material.
Expansion problem: During the charge and discharge process, lithium-silicon alloy will expand in volume, which may cause the destruction of the material structure.
Cycle stability: Although it has a high theoretical specific capacity, cycle stability is still a challenge in practical applications.
Conductivity: Pure silicon itself has poor conductivity and needs to be treated by special processes to improve its electrochemical properties.
