Abstract

With the explosive growth of China's electric vehicle industry, make an urgent demand for high-performance energy storage devices. Currently, the performance development of mainstream liquid lithium-ion batteries has significant shortcomings and is no longer able to fully meet the higher standards of the market. Solid-state batteries are regarded as the most promising next-generation electrochemical energy storage technology. This article systematically analyzes the technical advantages, challenges and future development trends of solid-state batteries. Research has found that the most core advantage of solid-state batteries lies in their extremely high safety and the potential to achieve high energy density, in addition to having a longer cycle life. However, its industrialization still faces many severe challenges, such as the unsatisfactory electrolyte materials, and high impedance and side reactions at the solid-solid interface, and the high manufacturing cost also restricts its development. This study indicates that solid-state batteries are a promising but highly challenging technology.
