5. Design Feature Confidential ThickerSeparator 20 μm separator is used in our batteries, compared with 12 μm or 16μm separator which widely adopted by other manufacturers, our battery has a higher safety guarantee. Thicker Steel Can 0.22mm steel cans are used in our batteries, compared with 0.18mm thick steel cans which widely used by other manufactures, our battery has a better structural stability. Lower CID Value The CID of the terminal is at a low value (0.9-1.2Mpa). When abusing status such as over-charge appears, the CID will react sooner, avoid fire or explosion occurs.
