Results are from Volfpack prototype cells under documented internal test conditions. Application performance requires validation against the intended load and environment.
Pouch-cell development range
From millifarads to tens of farads.
Volfpack is developing pouch cells across six capacitance levels for compact pulse-power, bridge-power, and application-evaluation work.
Cell selection and suitability are evaluated against the intended voltage, load profile, physical envelope, and operating environment.
Two development paths
Power for the immediate event. More energy for what comes next.
Volfpack's tested graphene supercapacitor platform supports current prototype work. The hybrid-capacitor programme is the development path toward larger cells and longer discharge windows.
Prototype development

Development programme
Hybrid capacitors
More stored energy for longer power events.Volfpack's pathway toward larger cells and longer discharge windows while retaining strong power-delivery characteristics.
- Larger pouch-cell formats
- Longer bridge-power windows
- Partner-led evaluation
From materials to application
Cell development starts with the power requirement.
Materials research
Published work examines graphene-enhanced activated-carbon electrodes for supercapacitor applications.
Pouch-cell development
Flat geometry allows the cell format to be developed around spaces that may not suit cylindrical components.
Cell-level testing
Prototype cells are characterised and cycled before progressing toward application evaluation.
Electronics integration
Cell selection is considered alongside charging, protection, power electronics, and the actual load.
Applications
For short, repeated, high-power events.
Preserve data
Provide short-duration energy for a controlled shutdown or final data operation when primary power disappears.
Complete the final transmission
Support connected devices that need to send a final message after a loss of primary power.
Supply repeated radio pulses
Store low-rate or harvested energy, then release it for wireless communication events.
Support peak loads
Handle brief demand from compact electronics, telemetry equipment, scanners, actuators, and access systems.
These are evaluation use cases. Suitability depends on the electrical load, physical constraints, environment, and service-life requirement.
Validated progress
Built through research, testing, and collaboration.
