Abstract

With the profound scientific and economic advances, people’s demand for electronic products is increasing daily. Lithium-ion batteries are broadly applied due to their significant advantages in weight, volume, and lifespan. The anode of a lithium-ion battery is the main component in the electronic reaction of lithium ions. The materials currently used for the anode of lithium-ion batteries are mainly LiFePO₄, ternary lithium batteries, and LiMnO₂. Sometimes lithium titanate and LiCoO₂ are also used. Different anode materials share their benefits and drawbacks regarding various aspects such as energy density, cost, cycle life, safety, and environmental effects. Material modification or surface coating of the positive electrode of lithium-ion batteries is currently a popular solution, which also has a significant influence on changing the market share of different positive electrode lithium-ion materials. At last, this paper discusses the modification schemes for different types of lithium-ion batteries in the future by reviewing the literature.
