大规模锂电储能模组浸没式热失控管理
Liquid-Immersed Thermal Runaway Management of Large-Scale Energy-Storing with Lithium-Ion Batteries
摘要
Abstract
For the thermal runaway management issue of large-scale lithium battery energy storage using 280 Ah battery modules,a submerged liquid cooling thermal control solution was employed to regulate the thermal runaway behavior of the modules.The thermal runaway propagation behaviors of battery modules under submerged and non-submerged conditions,as well as the characteristics of thermal runaway behavior under different types of immersion liquids and different thermal runaway triggering methods,were studied.The research results show that under non-submerged conditions,the module experienced thermal runaway propagation,with a peak temperature of 367.8℃.In contrast,under submerged conditions,the module did not exhibit thermal runaway propagation.Among the submerged scenarios,the peak temperature during thermal runaway triggered by overcharging was 227.1℃,higher than the peak temperature of 214.7℃observed in the nail penetration scenario.Hydrocarbon-based synthetic oil and dimethyl silicone oil demonstrated comparable capabilities in managing the thermal field and suppressing thermal runaway in the module.The former exhibited stronger heat dissipation capabilities,while the latter was more effective in reducing the peak temperature of the module.关键词
