层状氧化物正极钠电池有什么特点？

What are the characteristics of Sodium-ion Battery with layered oxide cathode?    

层状氧化物正极是钠电池中最贴近动力电池需求的技术体系，综合性能均衡，适配动力场景落地。其核心优势为能量密度高、电芯容量大、放电平台稳定、工艺技术成熟、量产兼容性强，能够满足电动车对续航和动力输出的基础需求，是目前入门级新能源乘用车、高速两轮电动车的首选钠电池体系。同时该体系也存在明显短板，相较于普鲁士蓝、聚阴离子体系，其循环寿命相对中等，长期循环衰减速度略快，原材料和制造成本更高，安全稳定性略逊于另外两类材料，因此不太适合需要超长寿命、极致性价比的大规模储能场景。

Layered oxide cathode is the technology system of sodium battery that is closest to the demand of power battery, with balanced comprehensive performance and suitable for power scene landing. Its core advantages are high energy density, large cell capacity, stable discharge platform, mature technology and process, and strong mass production compatibility, which can meet the basic needs of electric vehicles for battery life and power output, and is the preferred sodium battery system for entry-level new energy passenger vehicles and high-speed two-wheeled electric vehicles at present. At the same time, the system also has obvious shortcomings: compared with Prussian blue and polyanion systems, its cycle life is relatively medium, the long-term cycle attenuation speed is slightly faster, the raw material and manufacturing cost is higher, and the safety and stability are slightly inferior to the other two materials, so it is not very suitable for large-scale energy storage scenarios that require ultra-long life and extreme cost performance.
