What’s Inside a ViZn Flow Battery?

Li-Ion

How is it made?

1. Safe electrolytes blended

2. Local tap water onsite

3. Alkaline solution

Zinc

Oxide

Yellow

Prussiate

of Soda

1. Anolyte: Zinc oxide

2. Catholyte: Yellow prussiate of soda

3. Alkaline solution: KOH and NaOH

ViZn flow batteries:

redundant system protection

1. Ships dry & de-energized

2. Inherently safe chemistry

3. Non-flammable electrolytes

4. Seamless tanks

5. Built-in containment diaphragm

6. Steel container

7. Leak detection sensors

8. Emergency off button

9. Gravity fed draining & deactivation

10. De-energizes in <15 seconds

11. 24/7 remote monitoring

12. Built-in fire suppression

What if? Worst Case Scenario

If: Natural disaster, nearby explosion, or

structural failure penetrates the exterior and

spills all of the electrolyte.

ViZn:

• Easily neutralized with common

materials

• Easy to dispose of via local guidelines.

• Potentially sewerable

Lithium Ion:

• Toxic smoke

• Heavy metal cleanup site

• Battery materials are an accelerant

• Electric shock hazard w/ charged cells

• Firefighter hazard, H2O reactivity

Case Study: Solar + Storage Safe

Resilient Microgrid

• Challenges: solar storage, critical infrastructure

operability during disasters & outages while

preserving safety

• Solution: distributed generation for 120% of

critical power needs with solar. 20 Year life

matches solar.

• Result: Resiliency power for disaster & outage

recovery with safety.
