Products Description
Hard carbon capacity testing procedure recommendation: Rest 4h, 0.2C DC to 0V, 0.1C DC to 0V, 0.01C DC to 0V, 10μA DC to 0V, rest 3 min, 0.1C CC to 2V.
Hard carbon is a kind of hard carbon prepared from plant raw materials. It has excellent performance in low temperature, rate,
cycle and safety.
cycle and safety.
Advantage: As a negative electrode material for lithium-ion batteries, it exhibits excellent rate performance and high/low temperature performance. Used in lithium/sodium ion batteries and lithium-ion capacitors.
