01 · The Principle

Conventional Supercapacitor vs. PSC™.
The technological leap of printed graphene.

Conventional supercapacitors store energy electrostatically — a principle they share with PSC™. But while conventional supercapacitors remain rigid, bulky, and dependent on toxic solvents, PSC™ open up new possibilities: they are printed, flexible, and can be integrated directly into the product.

Why not a battery? Batteries and supercapacitors are two different types of energy storage: batteries store energy through chemical reactions (high energy density, low power density, limited lifespan), while supercapacitors store energy through electrostatic charging (high power density, instant recharging, long lifespan). These are complementary technologies, not competing ones.

02 · Applications

Where print makes all the difference.

Wherever a conventional supercapacitor is too bulky, too rigid, or impossible to integrate, PSC™s open up new applications.

May 1
Sustainable transportation

Bicycles & E-bikes — Regenerative Braking

When paired with the main battery, PSC™ units capture energy surges during braking and downhill riding and instantly deliver that power when accelerating and climbing. Flat design that integrates directly into the frame.

May 2
Internet of Things

Standalone IoT sensors

Ultra-thin, flexible design that can be integrated directly onto the PCB or sensor housing. Instant charging via energy harvesting (solar, thermal, vibration), with a lifespan matching that of the host product.

Drones

Hybrid battery + PSC™ architecture

PSC™ motors absorb power surges during takeoff and maneuvers, reducing the load on the battery so it can focus on providing flight time. This extends battery life, improves flight responsiveness, and features a flat design that integrates seamlessly into the frame.

Automotive & Transportation

Brake Energy Recovery

When paired with the main battery, PSC™ modules absorb the current surges from regenerative braking that would otherwise cause premature wear on a Li-ion cell. This extends battery life and improves overall energy efficiency.

Why Choose PSC™


The essentials, in a nutshell—three key points.

Behind every cell lies a printing process that combines performance, simplicity, and modularity.

01 —

Efficiency and cost-effectiveness.

By printing the cells instead of assembling them using traditional methods, we incorporate cutting-edge technology that ensures systems at a competitive cost, without compromising on quality.

Screen printing Industrial-scale production
02 —

Environmentally friendly and safe.

PSC™ cells use advanced materials for enhanced safety and reduced toxicity. No heavy metals or flammable solvents — simplified recycling, minimal environmental impact.

Organic materials No heavy metals Recyclable
03 —

Versatile and lightweight...

In sustainable transportation, weight is of paramount importance. The printing process allows for complete customization in terms of size, tension, and intensity, making it suitable for any type of OEM (Original Equipment Manufacturer) product.

05 · Manufacturing

Five steps.
An industrial pace.

The production of PSC™ cells relies on a reproducible, large-scale printing process that is compatible with various formats and mechanical constraints.

Step 1

Substrate preparation

Polymer films, technical papers, or composites are prepared for printing and to ensure the adhesion of the graphene layer.

Step 2

Printing of graphene electrodes

High-surface-area graphene inks are screen-printed onto the substrate to form the cell's active electrodes.

Step 3

Electrolyte deposition

The electrolyte is applied to the electrodes using a precision dispenser, ensuring uniform and reproducible distribution across the entire active surface.

Step 4

Assembly and heat sealing

The two half-cells are assembled and then heat-sealed, ensuring watertightness, electrolyte stability, and the mechanical integrity of the assembly.

Step 5

Individual test

Once encapsulated, each cell is individually tested for capacity, ESR (Equivalent Series Resistance), and under various atmospheric and mechanical conditions.
