The advantages of SK Group ‘s pouch cells include high energy density, long cycle life, safety and fast charging and discharging ：
1、 High energy density : SK pouch lithium batteries can provide considerable energy in a small size and light weight, which is conducive to the lightweight design of automotive battery systems
2、Long cycle life : SK pouch lithium batteries have a relatively long cycle life, reaching 500-800 charge and discharge cycles, which is much higher than the industry standard and reduces the degradation rate of the battery system
3、Safety : SK pouch lithium batteries use a professional battery management system that can effectively prevent safety issues such as overcharging, overdischarging and short circuit of the battery, improving the safety and reliability of the battery
4、Fast charging and discharging : SK pouch lithium batteries have a relatively fast charging and discharging speed, which can meet the charging speed requirements of electric vehicles and thereby increase the driving range
5、In addition, SK pouch batteries have also performed well in the application of electric vehicles. For example, the Arcfox Alpha series uses SKI pouch cells with an energy density of up to 194Wh/kg, which is far above the industry average, allowing the cells to lose 100kg of weight with the same charge, thereby increasing the range
