How is the anti-attenuation ability of Sodium-ion Battery?
钠离子电池的抗容量衰减能力十分优异,长期循环稳定性极强,使用寿命可控。得益于正负极材料稳定的晶体结构,钠离子嵌脱过程不会造成电极结构严重损伤,数千次循环过程中,电池容量呈平缓线性衰减,无突然跳水、断崖式衰减的情况。前期新电池衰减速度极慢,中后期衰减平稳温和,电池老化过程均匀,不会出现局部失效、整包报废的问题。对比铅酸电池后期快速硫化失效、锂电池局部衰减失衡,钠电池的长效稳定性和抗老化能力优势显著,适合长期商用运行。
Sodium-ion Battery has excellent anti-capacity attenuation ability and extremely strong long-term cycle stability, with controllable service life. Benefiting from the stable crystal structure of the cathode and anode materials, the intercalation and deintercalation of sodium ions will not cause serious damage to the electrode structure. During thousands of cycles, the battery capacity shows a gentle linear attenuation, without sudden drop and cliff-type attenuation. The attenuation speed of the new battery in the early stage is extremely slow, and the attenuation in the middle and late stages is stable and mild, and the battery aging process is uniform, without local failure and whole pack scrapping. Compared with the rapid sulfidation failure of lead-acid batteries in the late stage and the local attenuation imbalance of lithium batteries, the long-term stability and anti-aging ability of sodium batteries have significant advantages, which are suitable for long-term commercial operation.
