摘要
With the development of the world, energy issues have also been paid more and more attention. In order to further reduce reliance on non-renewable energy sources and protect the environment, reliance on electricity has also increased. The energy storage problem is inevitable in electricity use. With the development of new materials, the concept of lithium batteries was proposed and further explored. This article will introduce lithium batteries' principles, materials, advantages, and disadvantages. And the advanced cathode and anode materials and electrolyte materials of lithium-ion batteries (LIBS) are summarized in this paper to provide a state-of-art understanding of designing high-performance LIBs. Lithium dendrites are the culprit in reducing the cycle life of lithium batteries, and the accumulation of dead lithium produces them. In the face of lithium dendrites, one of the most difficult problems in lithium batteries, two typical solutions for eliminating lithium dendrites is discussed: the electrochemical polishing strategy and the self-heating-induced strategy. In general, several certain solutions have been proposed for lithium dendrites. However, to further improve the performance of lithium batteries and reduce the harm, new lithium dendrite solutions and material selection will become new problems.
