Six core technical parameters that affect the price of
18650 batteries.
1. Energy density game: High capacity battery packs with a capacity of over 3000mAh have a premium of 35%, and Tesla's 4680 battery technology has enabled the 18650 single cell capacity to surpass the 4000mAh threshold
2. Difference in discharge performance: Power type battery packs that support 15 year continuous discharge are priced 22-28% higher than regular types
3. Temperature control system configuration: The cost of the battery pack with integrated intelligent BMS protection board has increased by 18%, but the cycle life has been extended to 1200 times
4. Certification standard upgrade: Complies with UN38.3+UL2054 dual certification products with a premium of 12-15%
5. Packaging process innovation: Laser welded steel shell assembly is 9% more expensive than traditional dispensing process, but the explosion-proof level has been raised to IP68
6. Supply chain restructuring: The mass production of sodium ion batteries has reduced the cost of lithium battery raw materials by 7.3%, but the high dependence on imported separators still reaches 61%.
