6 FAQs about [Shape diagram of negative electrode materials for lithium batteries]

What are the limitations of a negative electrode?

The limitations in potential for the electroactive material of the negative electrode are less important than in the past thanks to the advent of 5 V electrode materials for the cathode in lithium-cell batteries. However, to maintain cell voltage, a deep study of new electrolyte–solvent combinations is required.

What are the different types of negative electrode materials for Li-ion batteries?

There are three main groups of negative electrode materials for Li-ion batteries. The materials known as insertion materials are Li-ion batteries' “historic” electrode materials. Carbon and titanates are the best known and most widely used.

How does a graphitic negative electrode work?

The copper collector of graphitic negative electrodes can dissolve during overdischarge and form microshorts on recharge. Preventing this is one of the functions of the battery management system (see 2.1.3). The electrode foils represent inert materials that reduce the energy density of the cell. Thus, they are made as thin as possible.

Can lithium ion batteries be used as negative electrodes?

Future research directions on porous materials as negative electrodes of LIBs were also provided. Lithium-ion batteries have revolutionized the portable electronics market, and they are being intensively pursued nowadays for transportation and stationary storage of renewable energies such as solar and wind.

Why should a negative electrode be mixed with graphite?

Mainly, the high solubility in aqueous electrolytes of the ZnO produced during cell discharge in the negative electrode favors a poor reproducibility of the electrode surface exposed to the electrolyte with risk of formation of zinc dendrites during charge. In order to avoid this problem, mixing with graphite has favorable effects.
