Current situation of the problem
As the operational years of energy storage power stations increase, energy storage batteries will experience varying degrees of capacity degradation and increased internal resistance, leading to significant reductions in operational profits. Additionally, in recent years, with consumers' growing demands for battery performance and safety, the R&D costs of major battery manufacturers have nearly accounted for 4% to 6% of total R&D expenditure rates.
