Research on the application of electrode materials for batteries

Abstract

In the world, ecological environment and energy problems seriously restrict the sustainable development of each country and society. Therefore, it is essential to eliminate fossil energy dependence and develop and utilise new energy, especially in electric vehicles. This requires the use of secondary batteries to achieve efficient energy storage. In this paper, several potential energy storage technologies Ni-HM, Li-ion and PEMFC, are compared, and the application prospect, existing problems and the primary performance of these three battery technologies are analysed. This paper examines the standard preparation technology, reaction mechanism, background and advantages and disadvantages of these three kinds of batteries. Then the problems faced by the application of these three battery technologies, including specific energy, energy density, specific power, energy storage cost, cycle life, energy efficiency, safety, etc., are analysed, and through the main performance comparison of these three battery technologies, to provide a new idea in the battery area. Through the analysis and comparison of these batteries, the Li-ion battery has the greatest all-around performance, so it is also the optimal solution to solve environmental and energy problems. Secondly, Ni-MH batteries in all aspects of the commission are very general; the current technology still lacks competitiveness, and many vital areas need further research. Finally, the PEMFC have significant advantages in energy density, energy storage cost, and specific energy, so this technology is a potential technology worthy of further study.
