Customer ServiceAbstract Among high-capacity materials for the negative electrode of a lithium-ion battery, Sn stands out due to a high theoretical specific capacity of 994 mA h/g and the presence of a low-potential discharge plateau. However, a significant increase in volume during the intercalation of lithium into tin leads to degradation and a serious decrease in capacity. An
Customer ServiceThe anode in a SIB acts as the negative electrode, accepting sodium ions during charging and releasing them back into the electrolyte during discharge. Since sodium ions are larger than lithium ions, similar to the cathode, the anode material needs to have a structure that can handle this size difference and allow for efficient sodium ion movement.
