Lithium battery materials Benefiting from the development of downstream new energy vehicles, global power battery shipments have increased by more than 100 times in 8 years. Since 2011, new energy vehicles have entered a period of rapid development, and sales of new energy passenger vehicles in China reached 1.367 million units in 2020. As a major midstream industry, power batteries have also entered an explosive period, and global power battery shipments have risen from 1.08GWh in 2011 to 106GWh in 2018, an increase of more than 100 times in eight years. In the past few years, deposition/stripping electrochemistry-based metal anodes such as metals Li, Na, K, Zn, Mg, Ca, Al, and Fe have attracted a lot of attention due to their high theoretical specific capacity, lower electrochemical potential, and high electron conductivity, and metal anodes can be paired with positive electrodes to construct high energy density rechargeable metal batteries. Problems inherent in the battery cycling process include large volume variations, infinite dendrite growth, and unstable solid-electrolyte interphase (SEI) that hinder their further development. The use of MXene as an additive or conductive matrix in cathodes, anodes and separators greatly suppresses the shuttle effect, and considerable achievements have been made in lithium-ion batteries. In the upcoming era of electric vehicles will inevitably shine, hundreds of billions of dollars of power battery market, MXene will inevitably be able to get a piece of the pie.
