钠电池充电速度快吗？

Is the charging speed of Sodium-ion Battery fast?    

钠离子电池具备优异的快充性能和大倍率充放电能力，倍率性能远超普通锂电池和铅酸电池。得益于钠离子迁移阻力小、电极嵌脱速度快的特性，主流商用钠电池支持1C-2C常规快充，高端动力级钠电池可支持3C以上超大倍率快充。日常使用中，常规钠电池可实现30分钟内充至80%以上电量，40分钟左右满电，完全满足民用设备、电动车的快充需求。同时其大电流充放电稳定性好，无明显发热、衰减加剧问题，适配储能电站调频调峰、电动车瞬时动力输出等大功率场景，快充体验极佳。

Sodium-ion Battery has excellent fast charging performance and high rate charge and discharge capability, and the rate performance is far better than that of ordinary lithium batteries and lead-acid batteries. Benefiting from the characteristics of low sodium ion migration resistance and fast electrode intercalation and deintercalation speed, mainstream commercial sodium batteries support 1C-2C conventional fast charging, and high-end power grade sodium batteries can support more than 3C ultra-high rate fast charging. In daily use, conventional sodium batteries can be charged to more than 80% of the power within 30 minutes, and fully charged in about 40 minutes, which fully meets the fast charging needs of civil equipment and electric vehicles. At the same time, it has good stability under high current charge and discharge, without obvious heating and accelerated attenuation problems, and is suitable for high-power scenarios such as frequency modulation and peak shaving of energy storage power stations and instantaneous power output of electric vehicles, with excellent fast charging experience.
