Can Sodium-ion Battery be used for grid energy storage?    

钠离子电池已成为新型电力系统电网储能的核心主力电池，广泛应用于各类电网储能项目。电网储能需要电池具备安全稳定、成本低廉、循环寿命长、可大规模集成、适配高低温环境、支持调峰调频的特性，钠电池完全满足所有需求。在电网侧，钠电池储能系统可实现电网削峰填谷，白天吸纳光伏、风电多余电能，晚间高峰释放电力，平衡电网负荷；可参与电网调频、调压，快速响应电网功率波动，稳定电网电压和频率；可作为电网备用储能，应对突发断电、电力缺口；同时助力新能源消纳，解决风电、光伏间歇性、波动性发电难题，大幅提升新能源并网利用率。

Sodium-ion Battery has become the core main battery for grid energy storage in the new power system, and is widely used in various grid energy storage projects. Grid energy storage requires batteries to have the characteristics of safety and stability, low cost, long cycle life, large-scale integration, adaptation to high and low temperature environments, and support for peak shaving and frequency modulation, which are fully met by sodium batteries. On the grid side, the sodium battery energy storage system can realize peak shaving and valley filling of the power grid, absorb excess electric energy from photovoltaic and wind power during the day, and release electric energy during the evening peak hours to balance the power grid load; it can participate in grid frequency modulation and voltage regulation, quickly respond to grid power fluctuations, and stabilize grid voltage and frequency; it can be used as grid backup energy storage to cope with sudden power outages and power gaps; at the same time, it helps to consume new energy, solve the problem of intermittent and volatile power generation of wind power and photovoltaic, and greatly improve the grid-connected utilization rate of new energy.
