Abstract

The application of new-type solid-state batteries in distributed energy systems is gradually demonstrating potential advantages, and the comprehensive evaluation of their safety and economy has become a research focus. By analyzing the improvements of solid-state batteries in thermal stability, cycle life, and failure mechanism, their advantages in preventing thermal runaway and reducing operation and maintenance risks can be highlighted. Meanwhile, by comparing the differences between solid-state batteries and traditional lithium-ion batteries in terms of investment cost, life-cycle cost, and energy conversion efficiency, it can be found that solid-state batteries have strong long-term economic competitiveness in distributed energy scenarios. The promotion of new-type solid-state batteries not only helps improve the operational safety of distributed energy systems but also promotes the optimization of energy structure by reducing comprehensive costs, providing strong support for the sustainable development of the future energy system.
