Safety comparison of lithium iron phosphate battery and ternary lithium battery

Controversy over the safety of ternary and lithium iron phosphate has continued for two or three years. There have been divergent opinions about which battery should be used in commercial electric vehicles. Previously, there was a compromise view in the industry: different models use different batteries, such as Passenger cars value the driving range and use high specific energy ternary batteries. Passenger cars pay more attention to safety and use lithium iron phosphate with relatively low specific energy but higher stability. Because the ternary lithium battery will be analyzed at about 200 degrees, and there will be more violent chemical reactions after the analysis, it is more likely to catch fire when a car crashes. This is also the place where ternary lithium batteries are generally considered unsafe, precisely because The original ternary lithium battery was previously suspended from use in passenger cars. However, the safety is more dependent on the entire power lithium-ion battery system, especially the battery management system. A qualified BMS can cut off the power supply to be on fire in the event of an accident, and it cannot be just because the ternary lithium material is easy to pyrolyze. The ternary lithium battery is considered unsafe. With the reassessment of the safety of ternary lithium batteries, passenger cars will lift the ban on ternary lithium batteries, which undoubtedly releases a large part of the market. Although there is no clear conclusion about the market battle between lithium iron phosphate and ternary, and battery technology is changing with each passing day, revolutionary changes are expected in the near future. The mature technology of ternary batteries, with Its energy density is high and there is still a lot of room for improvement, not inferior safety, low temperature resistance, high charging efficiency and other characteristics, will gain a firm foothold in the new market.
