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. An

How does a lithium-Ion battery work?

When the lithium-ion battery in your mobile phone is powering it, positively charged lithium ions (Li+) move from the negative anode to the positive cathode. They do this by moving through the electrolyte until they reach the positive electrode. There, they are deposited. The electrons, on the other hand, move from the anode to the cathode.

Lithium-ion battery fundamentals and exploration of cathode

Since lithium metal functions as a negative electrode in rechargeable lithium-metal batteries, lithiation of the positive electrode is not necessary. In Li-ion batteries, however, since the carbon electrode acting as the negative terminal does not contain lithium, the positive terminal must serve as the source of lithium; hence, an intercalation compound is necessary

Is lithium a good negative electrode material for rechargeable batteries?

Can graphites be used as negative electrode materials in lithium batteries?

There has been a large amount of work on the understanding and development of graphites and related carbon-containing materials for use as negative electrode materials in lithium batteries since that time.
