Lithium-ion battery overview
The history of lithium-ion batteries started in 1962. The first battery was a battery that could not be recharged after the initial discharging (primary battery). The materials were lithium for the negative electrode and manganese dioxide for the positive electrode. This ...
Materials of Tin-Based Negative Electrode of Lithium-Ion Battery
Abstract 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 …
