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 decrease in capacity.
How do batteries work? A simple introduction
When a zinc-carbon battery is wired into a circuit, different reactions happen at the two electrodes. At the negative electrode, zinc is converted into zinc ions and electrons, which provide power to the circuit. At the positive electrode, manganese (IV) oxide turns to manganese (III) oxide and ammonia.
