company news about Comparison of core indicators: sodium battery vs lithium battery&lead-acid battery

1.

Upstream mineral resource raw materials:

Sodium ion batteries: Rich in raw materials, relatively abundant in domestic resources

Lithium electronic batteries: Lithium resources are sufficient but unevenly distributed

Lead acid batteries: Rich in raw materials and abundant in domestic resources

2.

Unit energy raw material cost:

Sodium ion battery: 0.35-0.7 yuan/Wh

Lithium iron phosphate battery: 0.3~0.5 yuan/Wh

Ternary lithium battery: 0.5~0.7 yuan/Wh

Lead acid battery: 0.40 yuan/Wh

3.

Cost of individual batteries:

Sodium ion battery: calculated by Hu Yongsheng, founder of Zhongke Haina, with a promotion period of 0.5-0.7 yuan/Wh; Development period: 0.3-0.5 yuan/Wh; The outbreak period is below 0.3 yuan/Wh. Among them, the cost of sodium ion batteries on the 1GWH production line of Zhongke Haina and Huayang Co., Ltd. after being put into production after 2023 is approximately 0.5-0.7 yuan/Wh

Lithium iron phosphate battery: the average cost of lithium iron phosphate battery in the industry is 0.4 yuan/Wh, including Ningde Times CTP

Ternary lithium battery: around 0.7 yuan/Wh

Lead acid battery: 0.3 yuan/Wh (considering battery recycling)

4.

Number of cycles:

Sodium ion batteries: 1200-2000 cycles (100% DOD), with a product (non laboratory data) cycle count of 4500 cycles (≤ 90%) published by Zhongke Haina in 2021

Lithium iron phosphate battery: 3000 times - 6000 times. At present, the cycle times of lithium iron phosphate battery commercial products are generally more than 3000 times;

Ternary lithium battery: 1000-2000 times

Lead acid batteries: 300-500 cycles

5.

Single mass energy density:

Sodium ion battery: 80-150Wh/kg (related to cutoff voltage)

Lithium iron phosphate battery: 150-190Wh/kg;

Ternary lithium battery 180-280Wh/kg

Lead acid battery: 30-50Wh/kg

6.

Low temperature performance (-20 ° C capacity retention)

Sodium ion batteries: less than 80%

Lithium iron phosphate battery: less than 70%

Ternary lithium battery: greater than 70%

Lead acid batteries: less than 60%

(Actually, this is a major drawback of sodium ion batteries, not an advantage. The battery voltage range is too wide, and the actual available voltage range is limited after series and parallel connection.)

7.

Security:

Sodium ion battery: good

Lithium iron phosphate battery: good

Ternary lithium battery: general

Lead acid battery: excellent

8.

Environmental performance:

Sodium ion battery: excellent

Lithium iron phosphate battery: excellent

Ternary lithium battery: excellent

Lead acid batteries: poor
