Grid-Grade Rechargeable Batterie and Predication in Future

Abstract

China is in a period of the energy transition; more renewable energy is used to replace coal which has caused more and more environmental issues. Researches on energy storage play a significant role in the government’s future sustainable development plans. In this article, four types of rechargeable batteries’ characteristics will be explored and their applications for grid-scale energy storage. The Lithium-ion battery is the most well-established with the less exploring room one. Then Nickel-metal hydride battery, due to the complexity of its reaction condition and electrode materials, still retains room for exploration after decades of development. Mn-Cu battery and Mn-H battery have the shortest development cycle and are mostly still in the experimental research stage. The rechargeable battery is one of the most promising energy storage technologies in the future, but there are many kinds of rechargeable batteries, only part of which can be applied to hydropower storage. In this article, four types of rechargeable batteries are listed in different development stages. By analyzing and comparing their performance, the feasibility of grid-level energy storage is summarized, and the future development direction of them is predicted.
