To accelerate the commercial application of solid-state batteries, the paper investigates the thermal runaway characteristics of pouch-type semi-solid battery cells and small modules. The study reveals that compared to conventional liquid electrolyte batteries, semi-solid batteries exhibit more violent reactions during thermal runaway, characterized by intense combustion accompanied by a large amount of high-temperature and high-pressure gas and internal active material ejection, with maximum temperatures exceeding 1 300 ℃. Based on these characteristics, the paper proposes a battery module solution integrating “directional venting” and “multi-level thermal insulation” safety design combined with an efficient cooling system. This solution effectively suppresses the propagation of thermal runaway after cell failure, and the directional venting design at the module level significantly reduces the complexity of thermal safety design for battery systems and enhances the thermal safety reliability of battery packs.

为了加速实现固态电池商业化应用,对软包半固态电芯单体及小模块的热失控特性展开研究,相较于传统液态电池,半固态电池在热失控过程中反应更为剧烈,表现为剧烈燃烧并伴随大量高温高压气体及内部活性物质喷发,最高温度超过1 300 ℃。基于此特性,提出了一种集成“定向排气”与“多级隔热”安全设计、并结合高效冷却系统的电池模组方案。该方案有效抑制了电芯热失控后的蔓延,模组层级的定向排气设计显著降低了电池系统热安全设计的复杂度,提升了电池包的热安全可靠性。

为了加速实现固态电池商业化应用,对软包半固态电芯单体及小模块的热失控特性展开研究,相较于传统液态电池,半固态电池在热失控过程中反应更为剧烈,表现为剧烈燃烧并伴随大量高温高压气体及内部活性物质喷发,最高温度超过1 300 ℃。基于此特性,提出了一种集成“定向排气”与“多级隔热”安全设计、并结合高效冷却系统的电池模组方案。该方案有效抑制了电芯热失控后的蔓延,模组层级的定向排气设计显著降低了电池系统热安全设计的复杂度,提升了电池包的热安全可靠性。

To accelerate the commercial application of solid-state batteries, the paper investigates the thermal runaway characteristics of pouch-type semi-solid battery cells and small modules. The study reveals that compared to conventional liquid electrolyte batteries, semi-solid batteries exhibit more violent reactions during thermal runaway, characterized by intense combustion accompanied by a large amount of high-temperature and high-pressure gas and internal active material ejection, with maximum temperatures exceeding 1 300 ℃. Based on these characteristics, the paper proposes a battery module solution integrating “directional venting” and “multi-level thermal insulation” safety design combined with an efficient cooling system. This solution effectively suppresses the propagation of thermal runaway after cell failure, and the directional venting design at the module level significantly reduces the complexity of thermal safety design for battery systems and enhances the thermal safety reliability of battery packs.
