Is the safety of ternary lithium batteries used in electric sweeping vehicles safe? The ternary lithium batteries are unreliable in terms of safety. In this case, the impact will damage the battery gap and cause a short circuit. The heat declared during the short circuit will cause the battery to lose control of the heat and quickly increase the temperature to above 300°C. Ternary lithium batteries have poor thermal stability, and oxygen molecules will decompose below 300°C. When the battery encounters combustible electrolyte and carbon data, the heat that appears will further aggravate the decomposition of the positive electrode, and deflagration occurs in a short period of time. In contrast, another widely used lithium iron phosphate battery can last 700-800 degrees Celsius and is safer without decomposing oxygen molecules. For safety reasons, passenger cars carrying ternary lithium batteries in my country cannot be included in the new energy car catalog of the Ministry of Industry and Information Technology. Lithium battery is a mobile bomb. In addition to the notorious Samsung note due to battery explosions, the Boeing 787 was also affected. The 787 is the world's first civilian aircraft to use lithium batteries. In January 2013, after two lithium battery fires, the aircraft was forced to ground, which prompted Airbus to abandon its plan to use lithium batteries on the A350. In 2017, among the pure electric vehicles sold in my country, ternin (parameters | graph) lithium batteries accounted for 44.01% of the total installed capacity, while lithium iron phosphate batteries still accounted for the majority. However, more and more power lithium-ion battery companies are turning to ternary lithium batteries in order to seek the energy density of the battery. Even BYD, which has long been in the lithium iron phosphate camp, has begun to rebel. However, Tesla is known for its excellent battery handling system, and it is still unable to get rid of the shadow of car fires. Judging from the current quality of domestic new energy vehicle plants, the popularity of ternary lithium batteries is too fast, which is not necessarily an advantage. So I personally suggest that it is best not to use ternary lithium batteries for sweepers! Statement: Some pictures and content of articles published on this site are from the Internet.
