钠电池的电压等级一般是多少？

Is Sodium-ion Battery a new energy battery?    

商用单体钠离子电池的标准标称电压约为3.0V，是行业通用基准电压，不同材料体系的钠电池电压会存在小幅浮动。横向对比主流动力电池：电压低于三元锂电池（标称3.7V），与磷酸铁锂电池（标称3.2V）高度接近、基本持平，电压差值极小。在实际应用中，单节电芯电压无法满足大功率、高电压设备需求，因此会通过多串电芯组合的方式提升总电压，搭配BMS均衡管理，适配电动车、储能电站、UPS等不同电压规格的设备场景，完全可以替代传统锂电、铅酸电池的电压适配体系。

Sodium-ion Battery belongs to the new clean energy new energy battery that the state focuses on supporting, and fully meets the core definition and industrial standards of new energy batteries. From the perspective of environmental protection attributes, sodium batteries do not contain toxic heavy metal pollutants such as cobalt, nickel, lead, and mercury, have no high pollution emissions in the production process, and waste batteries can be efficiently recycled and regenerated, which is green, low-carbon and pollution-free; from the perspective of energy attributes, it is mainly used for energy storage of clean energy such as photovoltaic and wind power, helping to consume new energy, and replacing traditional high-pollution fossil energy and lead-acid batteries; from the perspective of industrial positioning, it is the core incremental category in the fields of new energy storage and new energy low-speed power, and is included in the key development list of China's new energy industry and dual carbon strategy, and is an indispensable and important part of the new energy industry.
