磷酸铁锂电池的特点 

1.能量密度较高：

据报道，2018年量产的方形铝壳磷酸铁锂电池单体能量密度在160Wh/kg左右，2019年一些优秀的电池厂家大概能做到175-180Wh/kg的水平，个别厉害的厂家采用叠片工艺、容量做得大些，或能做到185Wh/kg。

2.安全性能好：

磷酸铁锂电池正极材料电化学性能比较稳定， 这决定了它具有着平稳的充放电平台，因此，在充放电过程中电池的结构不会发生变化，不会燃烧爆炸，并且即使在短路、过充、挤压、针刺等特殊条件下，仍然是非常安全的。

3.循环寿命长：

磷酸铁锂电池1C循环寿命普遍达2000次，甚至达到3500次以上，而对于储能市场要求达到4000-5000次以上，保证8-10年的使用寿命，高于三元电池1000多次的循环寿命，而长寿命铅酸电池的循环寿命在300次左右。

Features of lithium iron phosphate battery

1. Higher energy density:

According to reports, the energy density of the square aluminum shell lithium iron phosphate battery mass-produced in 2018 is about 160Wh/kg. In 2019, some excellent battery manufacturers can probably achieve the level of 175-180Wh/kg. The chip technology and capacity are made larger, or 185Wh/kg can be achieved.

2. Good safety performance:

The electrochemical performance of the cathode material of lithium iron phosphate battery is relatively stable, which determines that it has a stable charging and discharging platform. Therefore, the structure of the battery will not change during the charging and discharging process, and it will not burn and explode. It is still very safe under special conditions such as charging, squeezing, and acupuncture.

3. Long cycle life:

The 1C cycle life of lithium iron phosphate batteries generally reaches 2,000 times, or even more than 3,500 times, while the energy storage market requires more than 4,000-5,000 times, ensuring a service life of 8-10 years, which is higher than the ternary battery's more than 1,000 cycles The cycle life of long-life lead-acid batteries is about 300 times.
