What are the types of power batteries?

The types of power batteries include lithium manganese oxide batteries, lithium iron phosphate batteries, and ternary lithium batteries. The following is a detailed introduction: Characteristics of lithium manganese oxide batteries: Lithium manganese oxide batteries have low cost, good safety, and excellent low-temperature performance. However, the material itself is not very stable and tends to decompose, producing gas. Therefore, they are often used in combination with other materials to reduce cell costs. Characteristics of lithium iron phosphate batteries: They offer excellent thermal stability, safety, low cost, and long lifespan, but have low energy density and are sensitive to low temperatures. Their service life is also relatively long. However, the driving range of vehicles equipped with these batteries is generally limited. When the temperature drops below -5°C, charging efficiency decreases, making them unsuitable for winter charging needs in northern regions. Characteristics of ternary lithium batteries: Ternary lithium-ion batteries have high energy density, long cycle life, and are resistant to low temperatures. However, their stability at high temperatures is insufficient. They can achieve the highest energy density, but their high-temperature performance is relatively poor. For pure electric vehicles with demanding range requirements, they are the mainstream choice and are suitable for northern climates, as the batteries remain more stable in low temperatures.
I've been working in repair shops for nearly twenty years, and there are three common types of power batteries: Lead-acid batteries are the oldest, used in electric vehicles and jump starters—affordable but heavy and short-lived, needing replacement every two to three years. Nickel-metal hydride (NiMH) batteries are popular in hybrids, like Toyota's Prius, lighter and less polluting than lead-acid. Lithium-ion batteries are the current favorite, used by Tesla—high energy density and fast charging, but costly, requiring careful handling to avoid circuit overheating. I've handled several lithium battery failures, mostly performance degradation due to overheating. I advise owners to regularly check battery health and maintain them promptly to extend lifespan—don’t delay repairs to save money until they’re beyond repair.
