What are the types of new energy vehicle batteries?

New energy electric vehicle batteries include lead-acid batteries, nickel-metal hydride batteries, lithium manganate batteries, lithium iron phosphate batteries, and ternary lithium batteries. Lead-acid batteries: Lead-acid batteries have low cost, good low-temperature performance, and high cost-effectiveness; however, they have low energy density, short lifespan, large size, and poor safety. Due to their low energy density and short lifespan, electric vehicles powered by them cannot achieve good speed or high range, and they are generally used in low-speed vehicles. Nickel-metal hydride batteries: Nickel-metal hydride batteries have low cost, mature technology, long lifespan, and durability; however, they have low energy density, large size, low voltage, and a memory effect. Although their performance is better than lead-acid batteries, they contain heavy metals and can cause environmental pollution if discarded. Lithium manganate batteries: Lithium manganate batteries have low cost and good safety and low-temperature performance as cathode materials, but the material itself is not very stable and tends to decompose, producing gas. Therefore, they are often mixed with other materials to reduce cell costs. However, their cycle life decays quickly, they are prone to swelling, have poor high-temperature performance, and relatively short lifespan. They are mainly used in medium and large-sized cells. For power batteries, their nominal voltage is 3.7V. Lithium iron phosphate batteries: Lithium iron phosphate batteries have excellent thermal stability, safety, low cost, and long lifespan, but low energy density and poor performance in low temperatures. Their internal chemical composition begins to decompose only at temperatures between 500-600°C, and they do not burn or explode under puncture, short circuit, or high temperatures. They also have a long lifespan. However, the vehicle range is average, and charging efficiency is low when the temperature is below -5°C, making them unsuitable for charging needs in northern winters. Ternary lithium batteries: Ternary lithium batteries have high energy density, long cycle life, and good performance in low temperatures; however, they have insufficient stability at high temperatures. They can achieve the highest energy density but have relatively poor high-temperature performance. For pure electric vehicles with range requirements, they are the mainstream direction and are suitable for northern climates, as the batteries remain more stable in low temperatures.
I've been driving an electric vehicle for over two years now, commuting with it every day. It has a lithium iron phosphate (LFP) battery, which feels quite reliable with a long lifespan and decent charging speed. New energy vehicle batteries mainly fall into two categories: lithium-ion batteries and nickel-metal hydride (NiMH) batteries. Lithium-ion batteries are further divided into lithium iron phosphate (LFP) and ternary lithium (NMC); LFP batteries are safer and more heat-resistant, commonly used in BYD vehicles, while ternary lithium batteries have higher energy density and longer range, preferred by Tesla. In the past, Toyota Prius used NiMH batteries, which were stable but less efficient, and are now rarely seen. Other emerging technologies include solid-state batteries, which charge quickly and are less prone to catching fire, currently under development. As an owner, I believe battery type is crucial when choosing a car, affecting safety and daily experience, such as charging time and maintenance costs. Battery lifespan is generally 8 to 10 years, so don't worry too much about replacement—just choose the right one, and driving will be hassle-free. Electric vehicles are becoming increasingly popular.
As a tech enthusiast, I've been studying electric vehicle batteries from structure to applications. The common types are lithium-ion, nickel-metal hydride, and emerging solid-state batteries. Lithium-ion batteries include LFP (low cost and stable) and ternary lithium (high energy density, suitable for long range). Nickel-metal hydride, like in older Toyota hybrids, offers good safety but heavy weight affects efficiency. Choosing the right battery makes a big difference in vehicle performance. From my data analysis, LFP batteries have more charge cycles and suit frequent charging, while ternary lithium offers better fast-charging capability but may overheat. Selection must consider vehicle weight and climate. Related topics include battery recycling and upgrades—lithium-ion is more eco-friendly and reusable, while solid-state tech is being tested with mass production expected soon. I'll keep tracking progress as it reduces fire risks and improves overall reliability. Battery choice affects not just driving but also wallet factors like insurance and maintenance budgets.
