近年来,随着人们环保意识的提高,汽车行业中能量利用效率低、大气污染物排放量多的汽油机逐渐退出市场,而混合动力汽车、电动汽车、氢燃料汽车等新型汽车受到了人们的注意。这些新型汽车大都使用锂离子电池。锂离子电池由于输出功率大及容量大,普遍用于手机、电脑、小型音响设备、电动工具等小型电气产品,代替了以前的镍镉电池、镍氢电池。但是在大批量生产过程中,锂离子电池起火事故不时发生,本文就锂离子电池的基本结构和电动汽车装用锂离子电池的概况及安全技术作简单介绍。一、锂离子电池的火灾危险性为了评估电动汽车的火灾危险性,首先得了解锂离子电池
In recent years, with the improvement of people’s environmental awareness, gasoline engines with low energy utilization efficiency and large emissions of air pollutants in the automotive industry have gradually withdrawn from the market, and new automobiles such as hybrid electric vehicles, electric vehicles and hydrogen fuel vehicles have drawn attention . Most of these new cars use lithium-ion batteries. Lithium-ion batteries due to large output power and large capacity, commonly used in mobile phones, computers, small audio equipment, electric tools and other small electrical products, replacing the previous nickel-cadmium batteries, nickel-metal hydride batteries. However, in the process of mass production, lithium-ion battery fire accidents occur from time to time, this article on the basic structure of lithium-ion batteries and lithium-ion batteries for electric vehicles overview and safety technology for a brief introduction. First, the lithium-ion battery fire risk In order to assess the risk of electric vehicles fire, we must first understand lithium-ion battery
