| Performance introduction： | Compared with the currently widely used lithium-silicon alloy, the unit cell assembled with lithium-boron alloy as the anode material has better performance in both the highest voltage and the discharge working time. Under different loads, the maximum voltage of the unit cell is increased by 0.10～0.27V compared with the lithium-silicon alloy, and the discharge time is extended by 11.4%～78.1%. | ||||||||||
| Appearance & Quality： | ●The surface of the product should have metallic luster without inclusions, holes and pits. | ||||||||||
| ● The edges of the product should be trim and without cracks. | |||||||||||
| ● Slight extrusion stripes are allowed on the surface of the product. | |||||||||||
| Packaging: | ● In the drying room, put the product into a metal can or aluminized polyester pouches that has been dried for more than 24H, and fill it with 99.999% dry argon. | ||||||||||
| ● The outer packaging is packed in corrugated cardboard boxes with more than 5 layers or steel drums, and the inner is tightly stuffed to prevent it from moving. | |||||||||||
