Product Specification Sheet
The Sodium-Ion based aqueous battery is a modular building block for clean energy storage
systems. Saltwater technology is the safest and most environmentally-friendly way of storing
electric power. It is particularly suitable for long-lasting stationary applications as in residential,
off-grid, micro-grid and industrial applications.
Some of the advantages of Sodium-Ion based batteries are:
✓ Non-toxic

✓ Safe to touch

✓ Non-corrosive

✓ Safe to transport and store (no ADR handling)

✓ Non-flammable

✓ Operating in a wide temperature range

✓ Non explosive

✓ Absolutely maintenance-free

✓ PH neutral electrolyte

Product Tests
Below please find some testing results which outline the behaviour of the product under
certain, specific test environments.

Overcharge Test
During and after the overcharge test of 500 hours constant charging at 8,0V and an average
current of 0,35A the battery met all test parameters.

Short Circuit Test

Resistance of the wire was 2 mΩ in the short circuit. Neither fire nor explosion, or any battery
deformation occurred during short circuit test.

Operation in high temperature ranges
At higher temperatures between 40°C and 50°C the battery’s efficiency improves and the
capacity increases. If 50°C is exceeded, the high temperatures cause evaporation of the
electrolyte and lead to increased gas evolution. In consequence the battery’s lifetime may
shorten.

Imbalanced Charging
Tested at 25°C with a 48VDC stack
5A charge/discharge current and charging and discharging voltage: 35,2V – 60V
Outcome

No explosion
No fire
No release of toxic gases
No voltage out of control
No accumulation of combustible gases
