Ten advantages of nano silica gel battery: 

1. High gravimetric specific energy:

2. Long lifespan: GFMJ series: 8-15years of floating operation,

DMJ series: recharging circle reaches 500 times

CNJ series: circle time is 30% more than world standard.

3. Large current charge and discharge features

4. Operating environment: -40°C~+60°C

5. Low self-discharge: self-discharge rate<0.075%/day. 75% power left after 1 year storage.

6. Maintenance free

7. High capacity, small volume, light weight

8. Fast charging rate

9. Environmental protection without leakage

10. Service life 5-12 years

Materials Advantages:

1. German origin fumed silica of 15-20nm as gels. Its surface area is 100-1000 times of common gels.

2. operating environment: -40°C~+60°C

3. America 4BS seed material, making polar plate longer life with high and even distributed PbO2
