Study on sodium-ion anode material - Graphene battery

Abstract

Batteries are the most common form of energy storage. Sodium-ion batteries are gradually replacing traditional lithium-ion batteries, becoming a key factor restricting their safety, service life, energy density and capacity. With the continuous consumption of energy by human society, the increasing scarcity of mineral resources, and the increasingly severe environmental problems. It is an urgent task to seek new, renewable and clean energy. Sodium-ion battery is expected to be a new type of charge/discharge device because of its high energy conversion efficiency, high energy density, long cycle life, environmental friendliness and good economy. The development of new green and high-efficiency large-capacity energy storage technology is great significance for promoting China’s green and low-carbon energy development. It is great significance for the implementation of China’s “double carbon” strategy. Sodium-ion battery is the most important class of secondary batteries. Sodium-ion battery has high rate, good low temperature resistance, suitable for low salt concentration electrolyte, high safety and other characteristics. The sodium is abundant in the earth, low price, low REDOX potential. That is a class of secondary batteries with great application prospects. With the progress of society and the sustainable development of economy, people’s demand for sodium-ion batteries is also increasing. The “14th Five-Year Plan” New Energy Storage Development Implementation Plan clearly points out that is necessary to carry out the test and demonstration of a new generation of high energy density storage technology represented by sodium-ion batteries.
