摘要: 为了探究液态水基介质以浸没电池的方式应用在电池热失控抑制中的实际效果以及是否会带来二次灾害,本文设计了液态水基介质对满电1P9S-280 Ah串联电池模组长时间浸泡试验和热失控扩散抑制试验。结果表明,液态水基介质浸泡电池后在电池正极极柱和负极极柱间形成840~8 370 kΩ电阻,说明电池在液态水基介质中为弱放电,不会造成二次灾害;应用液态水基介质后,1P9S-280 Ah串联电池模组热失控最高温度为398.1 ℃,相邻电池最高温度为125.6 ℃,说明液态水基介质对电池热失控强度、电池热失控扩散的抑制效果明显。

Abstract: To explore whether the application of liquid water-based medium in battery thermal runaway suppression through immersion would cause secondary disasters and its actual effect on lithium battery thermal runaway suppression, this paper designed a long-term immersion test of a fully charged 1P9S-280 Ah series battery module in liquid water-based medium, as well as the suppression of thermal runaway propagation using liquid water-based medium. The results showed that an 840~8 370 kΩ resistance was formed between the positive and negative terminals of the battery after immersion in liquid water-based medium, indicating weak discharge of the battery in this medium and no risk of secondary disasters. Following the application of liquid water-based medium, the maximum temperature during the battery thermal runaway of the 1P9S-280 Ah battery series module was 398.1 ℃, and the maximum temperature of adjacent batteries was 125.6 ℃, demonstrating the significant suppression effect of liquid water-based medium on battery thermal runaway intensity and propagation.
