What are the common types of automotive batteries used in new energy vehicles

Based on years of experience, the choice of battery for new energy vehicles directly determines the core dimensions of the vehicle usage experience-range, safety, cost, and convenience. I have seen many cases where users ignored the matching between battery type and their own needs, leading to a "halving" of winter range or inconvenience in daily energy replenishment. Therefore, it is necessary to systematically sort out the battery characteristics of mainstream models.

Analysis of Mainstream Battery Types and Representative Models

1️⃣ Ternary Lithium Battery: The Preferred Choice for Low-Temperature Range and Fast Charging

Thanks to the characteristics of nickel-cobalt-manganese (or nickel-cobalt-aluminum) ternary materials, ternary lithium batteries generally have an energy density of 260-300Wh/kg and outstanding low-temperature performance-maintaining over 75% of their range at -20℃, and supporting ultra-fast charging technology (e.g., the Tesla Model Y Long Range version can replenish 600km of range in 10 minutes). The core advantages of such batteries lie in their high energy density and fast charging capability, making them suitable for users in cold northern regions or those with high-frequency long-distance travel needs. It should be noted that the thermal runaway temperature of ternary lithium batteries is about 200-300℃, which places higher requirements on the Battery Management System (BMS).

2️⃣ Lithium Iron Phosphate (LFP) Battery: A Balance of Safety and Cost

LFP batteries do not contain precious metals, with a cost 15%-20% lower than ternary lithium batteries, a cycle life of over 3000 times, and a thermal runaway temperature of more than 800℃, offering better safety. Taking the Wuling Hongguang MINIEV as an example, its LFP battery pack supports a usage cost of 0.1 CNY per km per day, and there is no need to worry about range degradation in short-distance commuting scenarios. However, such batteries have weak low-temperature performance, with a typical range degradation of 30%-40% at -20℃, making them more suitable for commuting in southern cities or short-distance travel needs.

3️⃣ Blade Battery: An Upgraded Form of LFP Battery

BYD's Blade Battery is a structural innovation of LFP batteries. It improves space utilization by 50% compared to traditional LFP batteries through a long cell array design and has passed the nail penetration test (no open flame or smoke after piercing). The Blade Battery equipped in the Han EV Champion Edition reduces winter range degradation by 18% compared to traditional LFP batteries, while maintaining a daily usage cost of 0.1 CNY per km. It balances safety and winter practicality, making it a cost-effective choice for users in southern regions.

4️⃣ Swappable Ternary Lithium Battery: A Breakthrough in Energy Replenishment Convenience

The swappable ternary lithium battery adopted by the NIO ET5 Swap Version enables 3-minute fast battery swapping through standardized battery pack design and supports a battery rental model (a direct reduction of 70,000 CNY when purchasing a car). The core advantage of such batteries is solving range anxiety, especially suitable for users in first and second-tier cities-"gas station-style" energy replenishment can be achieved within areas covered by battery swap stations. However, attention should be paid to the regional coverage of swap stations (currently concentrated in core areas of first and second-tier cities).

Selection Recommendations for Different Demand Scenarios

Northern users / Long-distance needs: Prioritize ternary lithium battery models equipped with an intelligent thermal management system (e.g., Tesla Model Y), which has only 8%-15% range degradation at low temperatures, and its ultra-fast charging capability meets long-distance energy replenishment needs.

Commuting in southern cities: Blade Battery or LFP battery models (e.g., BYD Han EV, Wuling Hongguang MINIEV) are more advantageous, with high safety and low usage costs, and the daily cost can be controlled within 0.1 CNY per km.

Limited budget / Short-distance travel: LFP battery models such as the Wuling Hongguang MINIEV offer outstanding cost performance. A range of within 300km fully covers daily travel, and the battery cycle life is sufficient to support 5-8 years of use.

Tech-savvy early adopters: NIO battery swap models can be an option, but it is necessary to confirm the number of swap stations in the city in advance (it is recommended that the coverage radius does not exceed 5km) to avoid inconvenience in energy replenishment.

From industry data, ternary lithium and LFP batteries together account for more than 90% of the new energy vehicle battery market, representing mature technology routes verified by the market. It is recommended to prioritize mainstream brand models equipped with an intelligent thermal management system when making a selection-such systems can reduce range degradation by more than 50% through active temperature control, further improving the stability of battery performance.
