钠离子电池——破解寒区电储能困境的新选择

Sodium-ion battery:a new choice to solve the problem of electric energy storage in cold areas

我国陆地面积四成以上属于寒区,保障寒区部队的用电需求是后装保障能力建设的重要关切。其中,如何安全高效地储存电能则是寒区部队电能保障的首要难题。相较于当前应用广泛的磷酸铁锂电池、铅酸电池等,新兴的钠离子电池在低温性能、安全性、功率密度以及成本等方面均具有一定优势。本文通过对比分析认为,钠离子电池更适用于寒区的电能保障需求,将对破解我寒区部队的电储能困境发挥重要作用。建议相关建设部门和科研单位密切关注钠离子电池发展动态,积极布局和引导钠离子电池技术路线向寒区军事应用方向发展,大力推动钠离子电池在寒区军用储能电站和寒区装备电源等领域的工程应用与示范。

Over 40%of China’s land area falls under cold regions,and fulfilling the power demands of troops in these regions is an important concern for the construction of aftermarket support capability.Safe and efficient storage of electrical energy in cold regions is the primary problem impeding electrical energy guarantee for troops in these areas.Compared with the widely used lithium iron phosphate and lead–acid batteries,the emerging sodium-ion battery technology offers advantages such as low-temperature performance,safety,power density,and cost.Through comparative analysis,this study argues that sodium-ion batteries are more suitable for power supply in the cold regions and are expected to play a pivotal role in solving the problem of power storage for Chinese troops in these areas.This study recommends that the relevant construction departments and scientific research units pay close attention to the development of sodium-ion batteries,actively deploy and guide the technical route of this technology in the direction of military applications in the cold regions,and strongly promote the engineering application and demonstration of these batteries in fields such as military energy storage power stations and equipment power supplies in cold areas.
