钠电池能用于新能源汽车吗？

Can Sodium-ion Battery be used for new energy vehicles?    

钠离子电池可应用于入门级、短续航新能源乘用车，暂不适配高端长续航车型，目前已有多款钠电池新能源汽车实现量产上市。对于续航200-300公里的城市代步入门新能源车，用户主要用于日常通勤、市区短途行驶，对极致续航、轻量化要求不高，更看重购车成本、用车安全和电池稳定性，钠电池完全可以满足需求，且能大幅降低整车售价，提升车型性价比。而高端新能源汽车需要高能量密度、长续航、轻量化电池，受限于钠电池的能量密度短板，目前无法适配，仍需依靠三元锂电池、高端磷酸铁锂电池。未来随着钠电池技术迭代，续航能力提升后，适配车型将进一步拓宽。

Sodium-ion Battery can be applied to entry-level, short-endurance new energy passenger vehicles, and is not suitable for high-end long-endurance models at present. At present, a number of sodium battery new energy vehicles have been mass-produced and launched. For entry-level new energy vehicles with a battery life of 200-300 kilometers, users mainly use them for daily commuting and short-distance driving in urban areas, with low requirements for extreme battery life and lightweight, and more attention to the purchase cost, vehicle safety and battery stability. Sodium batteries can fully meet the needs, and can greatly reduce the vehicle price and improve the cost performance of the model. However, high-end new energy vehicles require high energy density, long battery life and lightweight batteries, which are limited by the shortcoming of low energy density of sodium batteries, and cannot be adapted at present, and still need to rely on ternary lithium batteries and high-end lithium iron phosphate batteries. With the technological iteration of sodium batteries and the improvement of battery life in the future, the range of adaptable models will be further expanded.
