Materials Design for High‐Safety Sodium‐Ion Battery

Abstract Sodium‐ion batteries, with their evident superiority in resource abundance and cost, are emerging as promising next‐generation energy storage systems for large‐scale applications, such as smart grids and low‐speed electric vehicles. Accidents related to fires and explosions for batteries are a reminder that safety is prerequisite for energy storage systems, especially when aiming for grid‐scale use. In a typical electrochemical secondary battery, the electrical power is stored and released via processes that generate thermal energy, leading to temperature increments in the battery system, which is the main cause for battery thermal abuse. The investigation of the energy generated during the…
