advantage：
- Innovative structure, good thermal stability, higher safety performance than the traditional battery; in the case of high temperature, overcharge, extrusion, acupuncture, etc., the probability of hot cell is reduced, effectively improving safety.
- The energy density per unit volume is one-third higher than that of traditional batteries, which brings better spatial performance for new energy;
- Light battery weight, corresponding to overcoming the weight consumption of energy reduction, improves battery life;
- Material cost performance ratio advantage is obvious.
