Organic Batteries

Detailed overview of innovation with sample startups and prominent university research

What it is

Organic batteries, also known as redox flow batteries or organic radical batteries, are a type of rechargeable battery technology that utilizes organic molecules as the active materials in the electrolyte. These batteries offer several potential advantages, including sustainability, environmental friendliness, and the potential for low cost and high scalability.

Impact on climate action

Organic Batteries in the Battery Storage domain advance climate action by offering sustainable energy storage solutions. By utilizing organic materials, these batteries reduce reliance on rare earth metals, lower environmental impact, and promote circularity. This innovation accelerates the transition to renewable energy, mitigating carbon emissions and combating climate change.

Underlying
Technology

Redox-Active Organic Molecules: Organic batteries use organic molecules that can undergo reversible oxidation and reduction reactions to store and release energy. These molecules are typically dissolved in a liquid electrolyte, which flows through an electrochemical cell.
Electrochemical Cell: The electrochemical cell consists of two electrodes separated by a membrane. The redox-active molecules in the electrolyte undergo reactions at the electrodes, generating an electric current during discharge and vice versa during charging.
Flow Battery Design: Organic batteries often utilize a flow battery design, where the electrolyte is stored in external tanks and pumped through the electrochemical cell. This allows for independent scaling of energy capacity and power output, making them highly scalable and adaptable to different energy storage needs.
