Environmental protection solid state granule silicon accumulator and environmental protection neutral secondary granule silicon dioxide solid state accumulator have basically settle the disadvantages of traditional lead-acid accumulator. Compared with the upgraded lead-acid accumulator, the granule silicon electrolyte can obviously improve the performance of the product, with high current, and better advantages in high/low temperature fields, thus achieving the requirements in high energy and maintenance free of the electric vehicle drive battery and high power traction accumulator. It remains leading in the world. The environmental protection of electrolyte can completely adapt the fashion of the industrial development in the 21st century.
　　Performance: granule silicon accumulator is the secondary granule silicon dioxide solid state valve control no-service accumulator, and is made by applying special technology and unique production technique, therefore, the comprehensive physical and chemical performance of the accumulator have reached the world leading level. The battery features high capacity, low internal resistance, low self discharging, durable for over-discharging, wide temperature range and long life. The circulation charging and discharging is over 500 times. The manufacturers in the world are searching for the new technique, new technology, new material and new structure for developing new products for meeting higher environment protection and use requirements. People have tried to achieve maintenance free accumulator for traction by applying various kinds of rubber electrolytes and new techniques. But their striving hasn’t got any result owing to the self features of lead-acid accumulator. The maintenance free solid state granule silicon valve control no-service accumulator for traction, secondary granule silicon dioxide can effectively restrain the harm of stibium, and the deep circulation life of the accumulator exceeds 1500 times, and it has also achieved no-service and maintenance free. It features favorable effect after using for such electric vehicles as electric bikes, electric tourist coach, golf cart, electric forklift and electric motors. Additionally, it boasts of super performance when it is used in motorcycle and motor starting, UPS, emergency lighting, railway, communication, solar energy and energy storage etc.
