21700 battery

Advantages of 21700 batteries

1. The energy density of the 21700 battery is higher than that of the well-known 18650 battery. The number of single batteries in use can be greatly reduced, and the cost will be reduced after grouping. , The capacity of a 18650 battery is about 2600-3600 mAh, and a 21700 battery supports more than 4000 mAh. Currently, 217005000mAh has appeared on the market. Larger capacities are increasingly beneficial for extending the battery life of modern devices.

2. The single volume of the rechargeable battery is increased by 35%. Taking the 21700 rechargeable battery produced by Tesla as an example, from 18650 to 21700, the energy of a single battery can be increased by 34.8ah, an increase of 35%.

3. The net weight of the system software is estimated to be reduced by 10%. The total capacity is more than 21,700. With the increase of the single volume and the increase of the single energy ratio, the total number of batteries required under the same kinetic energy can be reduced by about 1/3, and the total number of metal components and electrical components selected for the battery pack can reduce the difficulty of the management information system coefficient. After switching to the new 21700 rechargeable battery, Samsung's sdi found that the system software reduced the net weight by 10% compared to the existing battery.
