Can two-dimensional negative electrode materials be used in lithium-ion batteries?

CC-BY 4.0 . The pursuit of new and better battery materials has given rise to numerous studies of the possibilities to use two-dimensional negative electrode materials, such as MXenes, in lithium-ion batteries.

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.

Does real-time monitoring of NE potential improve battery performance and safety?

Real-time monitoring of NE potential is highly desirable for improving battery performance and safety, as it can prevent lithium plating which occurs when the NE potential drops below a threshold value. This paper proposes an easy-to-implement framework for real-time estimation of the NE potential of LIBs.

Are graphite negative electrodes prone to lithium plating?

The mainstream LIBs with graphite negative electrode (NE) are particularly vulnerable to lithium plating due to the low NE potential, especially under fast charging conditions. Real-time monitoring of the NE potential is a significant step towards preventing lithium plating and prolonging battery life.

What is the specific capacity of a negative electrode material?

Ideally, the specific capacity of a negative electrode material should be higher than 372 mA h g –1, that is, the specific capacity of graphite, which is the most commonly used negative electrode material at present.

Why is a lithium metal negative electrode important?

The lithium metal negative electrode is key to applying these new battery technologies. However, the problems of lithium dendrite growth and low Coulombic efficiency have proven to be difficult challenges to overcome.
