钠电池循环寿命有多长？

How long is the cycle life of Sodium-ion Battery?    

当前规模化商用的钠离子电池循环寿命表现优异，不同材料体系寿命略有差异，整体远超传统电池、比肩主流锂电。常规普鲁士蓝、层状氧化物体系钠电池循环寿命可达3000-4000次完整充放电循环；稳定性最优的聚阴离子体系钠电池，循环寿命可突破5000-6000次。对比来看，传统铅酸电池循环寿命仅300-500次，普通镍氢电池约800-1000次，主流磷酸铁锂电池循环寿命3000-6000次。钠电池的使用寿命是铅酸电池的10倍以上，长期使用无需频繁更换，大幅降低设备运维和替换成本，综合性价比优势显著。

The current large-scale commercial Sodium-ion Battery has excellent cycle life performance, with slight differences in the life of different material systems, which is far better than traditional batteries and comparable to mainstream lithium batteries. The cycle life of conventional Prussian blue and layered oxide system sodium batteries can reach 3000-4000 complete charge and discharge cycles; the polyanion system sodium battery with the best stability can have a cycle life of more than 5000-6000 cycles. For comparison, the cycle life of traditional lead-acid batteries is only 300-500 times, that of ordinary nickel-metal hydride batteries is about 800-1000 times, and that of mainstream lithium iron phosphate batteries is 3000-6000 times. The service life of sodium batteries is more than 10 times that of lead-acid batteries, which greatly reduces the cost of equipment operation and maintenance and replacement during long-term use, and has a significant comprehensive cost performance advantage.
