磷酸铁锂电池热失控特性及燃烧行为研究
Research on thermal runaway characteristics and combustion behavior of lithium iron phosphate batteries
摘要
Abstract
Under the background of the steady implementation of the dual carbon strategy and the global energy transformation,large-capacity lithium iron phosphate battery is widely used in battery energy storage power stations(BESS)due to its advantages such as high energy density and long life.However,the jet fire caused by thermal runaway of battery seriously restricts the further develop-ment of BESS.Delaying and preventing the group failure of battery modules under the influence of flame is a key concern.At present,there are few studies on thermal runaway combustion of large ca-pacity batteries and related key thermal runaway variation parameters.It is clear that the variation of each parameter in the process of battery thermal runaway is the premise of putting forward the suppression scheme.Thermal runaway experiments were carried out on 100 Ah single cell and four-cell module to explore the characteristic quantities such as temperature,heat release rate,mass loss and expansion force.The results show that the single-cell battery thermal runaway jet combustion ex-hibits a blowout phenomenon,with a maximum heat release rate of 20.6 kW and total heat release of 4.2 MJ.During the thermal spread process of the four-cell module,the maximum heat release rate reaches 76.9 kW and total heat release reaches 33.2 MJ.The research findings provide theoretical ref-erences for fire early warning,suppression,and firefighting in energy storage power stations.关键词
