In today’s society, electric vehicles are more and more favored by people. However, a careful eye will find that the types of batteries used by different electric vehicles at different prices vary. Why do cheap trams usually use lithium iron phosphate batteries, while more expensive trams tend to use ternary lithium batteries? Let’s explore the mystery. First of all, we need to understand the basic characteristics of lithium iron phosphate batteries and ternary lithium batteries. Lithium iron phosphate battery: 1. High safety: the P-O bond in the lithium iron phosphate crystal is stable, so it is not easy to react violently under extreme conditions such as high temperature or short circuit, reducing explosion, fire and other safety hazards. 2. Longer life: lithium iron phosphate batteries have more charge and discharge cycles, which means that the battery life is longer and the frequency of battery replacement is reduced. 3. Low cost:…
