Cospowers was invited by China Energy News, a subsidiary of People's Daily, and said:

"We are looking for newer, more efficient and lower cost solutions for energy storage batteries. For example, the sodium ion batteries that Cospowers is currently developing and promoting have more market advantages in terms of safety performance and cost in specific application scenarios." Energy storage technology progress and innovation is an important factor to promote the energy revolution. Continuous technological innovation and the pursuit of the safer, cost reduction and efficiency increase is the inexhaustible driving force of Cospowers product research and development.

Sodium ion battery introduction

Sodium-ion battery is a secondary battery (rechargeable battery), and produce current mainly depending on the interaction reaction between the material of positive and negative, whose working principle is similar with lithium battery, whose production can be made through using lithium battery production equipment, and whose industrial chain reuse rate reaches 80%, which is mainly composed of components of positive pole, negative pole, electrolyte, membrane, etc.

2.Under cost pressure, they are complementary brothers

The energy density of sodium ion is comparable to lithium iron phosphate, and combined with its low-cost advantages, it occupies a place in the field of low-speed electric vehicles and energy storage with low energy density requirements. From a cost perspective, sodium-ion batteries do not use expensive transition metals; On the other hand, the cheap aluminum foil is adopted for both positive and negative current collectors to replace the original more expensive copper; In addition, the amount of solute in the electrolyte of sodium ion battery can be greatly reduced. The overall cost will be 30% lower than lithium-ion batteries.
