Si is a negative electrode material that forms an alloy via an alloying reaction with lithium (Li) ions. During the lithiation process, Si metal accepts electrons and Li ions, becomes electrically neutral, and facilitates alloying. Conversely, during delithiation, Li ions are extracted from the alloy, reverting the material to its original Si ...
Lithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries due to its exceptional specific capacity (3860 mAh g −1), low electrochemical potential (−3.04 V vs. standard hydrogen electrode), and low density (0.534 g cm −3).
During the initial lithiation of the negative electrode, as Li ions are incorporated into the active material, the potential of the negative electrode decreases below 1 V (vs. Li/Li +) toward the reference electrode (Li metal), approaching 0 V in the later stages of the process.
As discussed below, this leads to significant problems. Negative electrodes currently employed on the negative side of lithium cells involving a solid solution of lithium in one of the forms of carbon. Lithium cells that operate at temperatures above the melting point of lithium must necessarily use alloys instead of elemental lithium.
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. Lithium–carbon materials are, in principle, no different from other lithium-containing metallic alloys.
The Li-Ion battery is manufactured by the following process: coating the positive and the negative electrode-active materials on thin metal foils, winding them with a separator between them, inserting the wound electrodes into a battery case, filling with electrolyte, and then sealing the battery case.
In commonly used batteries, the negative electrode is graphite with a specific electrochemical capacity of 370 mA h/g and an average operating potential of 0.1 V with respect to Li/Li +. There are a large number of anode materials with higher theoretical capacity that could replace graphite in the future.
