Lithium Battery Technologies for Improvement of Energy Efficiency

Abstract

With the process of economic globalization and the continuous improvement of energy demand, the search for new energy with higher efficiency has become a hot spot of social concern. Lithium-ion battery (LIB), as the current battery system with the best comprehensive performance, has the characteristics of high specific energy, high cycle life, small size and lightweight, and has rapidly developed into a new generation of energy storage power supply for information technology, new energy vehicles, aerospace and other fields of power support. Therefore, improving the energy efficiency of LIB is the most suitable choice in the current energy shortage. The core and key of LIB is the development and application of new lithium storage materials and electrolyte materials. This paper summarizes the research and application status of the main key materials of LIB. By analyzing the development status and existing problems of mainstream energy efficiency improvement technologies, it can be seen that the energy efficiency of LIB still has great room for improvement in the aspects of key materials and manufacturing technologies. At present, the research status of new anode materials and solid electrolytes is very active, and these technologies are expected to improve the energy efficiency, safety and reliability of lithium batteries. In the future, with more research and innovation, we can expect to see these technologies make even greater breakthroughs in the battery field, driving the development of electric mobility and renewable energy storage.
