- Stable internal resistance <1mΩ.
- Disconnect pressure balance at 10-15Mpa.
- The opening pressure is stable at 2.0-2.8Mpa; the explosion-proof performance is excellent and stable.
- Automated process control production, coated with high-tech sealant inside and outside, excellent air tightness.
- The shape design of the sealing ring fits beautifully with the roller groove of the steel shell of the battery, and the battery seal is smooth and tight, which is not easy to changeshape, no leakage.
- The environmental protection of the product complies with the ROHS standard.

The size is increased from 18650 to 21700, and the benefits are as follows:
- When the energy density is appropriately increased, conventional materials can be selected, with stable performance and high cost performance;
- The design of the multi-pole ear mechanism can be properly carried out to reduce the internal resistance;
- Under the same energy density, fast charging graphite can be selected to improve the fast charging performance;
- Appropriately increasing the diameter and height can obtain more effective volume.
- The capacity of the single battery cell is increased, the proportion of auxiliary components is reduced, and the cost of the pack is reduced.
Advantage
- Inhibit battery polarization, reduce thermal effects, and improve rate performance;
- Lithium-ion battery shell greatly reduces the internal resistance of the battery, and significantly reduces the dynamic internal resistance increase during the configuration process;
- Improve the uniformity and newly increase the configuration life of the battery;
- Lithium-ion battery shell improves the adhesion between active material and current collector, greatly reducing the manufacturing cost of tabs;
- Protect the current collector from being corroded by the electrolyte;
- Improve the high and low temperature performance of lithium-ion batteries, and improve the processing performance of lithium iron phosphate and lithium titanate materials.
