Product Introduction of the PLM-21700
This PLM-21700 is only the size and model of the battery, 21:represents the diameter of 21mm, 70:represents the length of 70mm, and 0:represents the cylindrical battery. The common 21700 batteries are divided into lithium-ion batteries with a capacity of 4800mah-5000mah, Usage of 21700 lithium battery:With the development of lithium batteries, lithium batteries are widely used, 21700 is now mainly used in Flashlight, Toy, Laser Pointer, Fan, Household Applications.Of course, the 21700 has excellent performance and is also one of the cost-effective lithium batteries.
Advantages：
1． Battery Density will increase
Power density of 21700 goes up to 300 Wh/kg, which is about 20% more than current 8650 batteries that rates at 250Wh/kg. so apparently 21700 battery power density is better than 18650 batteries, as it can increase by 20% or more Compared with 18650.
2． Battery Pack Price Decrease By 9%
Tesla further reveals the price of the 21700 lithium battery pack(with BMS) is expected to be sold for 155 USD/kWh, while 18650 size battery pack about US $185/kwh, that’s why you can notice a drop in prices by 9%.
3． More Miles to Go
21700 batteries, the battery pack could reduce about
10% of its weight compared to the current 18650 battery design. By reducing EV battery weight, and the vehicle’s energy density would be also improved, from this point of view, the EV car can go miles more.
