Abstract: Industrial agglomeration is an inevitable path for the energy storage industry to develop on a large scale. Based on the database of listed companies in China’s A-share market, the data of upstream and downstream enterprises in the energy storage industry chain from 2015 to 2020 are collected and collated, and the Herfindahl Index and Location Entropy Index are used to measure the degree of agglomeration of the energy storage industry in 30 provinces in China. The Location Entropy Index is selected as the descriptive variable for the degree of agglomeration of the energy storage industry in China and its evolutionary characteristics are analyzed from multiple dimensions including the overall situation, time, region, and industrial chain. The main findings are as follows: the agglomeration of China’s energy storage industry has gradually become more balanced, and there is a trend of transfer from high-agglomeration areas to the surrounding areas; the spatial heterogeneity is significant, with an “east–northeast–west” stepped agglomeration trend; the formation of agglomerated areas mainly relies on economic development, natural resources, and government support; and the agglomeration levels of enterprises at different positions in the industrial chain also show heterogeneity among regions. This article provides a theoretical basis for countries around the world to optimize the layout of the energy storage industry and build an innovative ecosystem for energy storage industry agglomeration.
