Operating principle

One compound.
Two charged reagents.

Charging separates sodium nitrite into sodium and nitrogen dioxide, storing electrical energy in the separated reagents.

Reversible cycle

Separate.
Recombine.
Repeat.

Charging stores electrical energy in separated reagents. Discharging reverses the reaction and returns electricity to the system.

SuperFuel battery

The chemistry is only the beginning.

The storage vessels, electrochemical stack, thermal management, power electronics, and control systems operate as one configurable machine.

01

Reagent storage

Purpose-designed vessels hold the combined and separated material states.

02

Planar cell stack

Series-connected electrochemical cells establish the system voltage architecture.

03

Thermal system

Application-specific equipment maintains the required operating states.

04

Power conversion

Grid-facing electronics convert, condition, and route electrical power.

05

Protection + controls

Isolation, monitoring, and supervisory control coordinate safe system operation.

Independent scaling

A deck of cards,
built to scale voltage.

Each planar cell contributes to the series stack. Add cells to change the voltage architecture without adding stored reagent. Increase reagent volume to add stored energy without changing the series stack.

Battery landscape

A different tradeoff
between density and duration.

SuperFuel retains the external-storage logic of a flow battery while using a different energy-bearing material. This architectural view shows where it sits beside established and emerging battery families.

Representative architectural and material-level comparison—not a claim of equivalent packaged-system performance. Formulations, system boundaries, operating conditions, and commercial configurations vary by supplier and application.

01

Energy outside the stack

Increasing material storage does not require rebuilding every electrochemical cell.

02

Voltage through series cells

The planar stack can be configured around the electrical requirements of the application.

03

Capacity through reagent volume

Stored-energy duration can grow through external vessel capacity rather than a fixed battery enclosure.
