REDCAP is a REDox CAPacitor

Metal – Free hybrid supercapacitor

Combines capacitive (supercapacitor) performance and faradaic (redox battery) responses, utilizing inexpensive and ubiquitous organic active species to deliver high power and energy in a simplified pouch design.

No critical minerals or materials. Off the shelf raw materials.
No geopolitical risk. Supply-chain independence.
No risk of thermal runaway / fire. Non-flammable electrolyte.
Equal or even more performance.
Lower cost and carbon footprint.

About us

Founded in 2018, REDCAP Energy is a Spanish deep tech company specialized in developing disruptive technologies for high-power energy storage systems. From the initial electrochemical concept to cell manufacturing and the industrialization of battery modules, the company covers the entire product lifecycle.

Built on a fully European value chain, REDCAP aims to strengthen Western strategic autonomy in sectors that rely on robust power stability such as grid management, security and defense, and data center infrastructure.

Today, REDCAP is operating a pouch cell pilot factory and supplying the first full power modules for commercial validation. In parallel we are launching the first industrial factory.
