Flint Paper Battery

The main challenge addressed by Flint lies in accelerating the global transition toward green energy, at a time when 84% of the world’s power still depends on fossil fuels. Over the past twenty years, only 2% of global energy production has shifted to renewable sources.

A key barrier to this transition is energy infrastructure, particularly battery technology. Today’s batteries are toxic, expensive, and reliant on rare materials such as lithium and cobalt. Recycling processes are inefficient and energy-intensive, while safety risks like overheating and chemical leaks remain a concern.

The question Flint seeks to answer is whether it is possible to design a battery technology that is entirely free from toxic and scarce elements, and in doing so, redefine how we power a sustainable future.
 

Flint has created a new class of paper batteries that store energy using natural materials instead of toxic or scarce elements. The design uses engineered cellulose reinforced with a hydrogel that functions as both separator and electrolyte, paired with zinc and manganese for safe and stable performance. The battery is water-based, fire safe, leak-proof, and remains functional even when cut. It composts within six weeks and produces no harmful waste.

Because it relies on abundant materials and low-temperature, water-based manufacturing, it is far cheaper and easier to scale than conventional batteries. This approach enables clean, accessible energy storage for consumer electronics, smart packaging, sensors, and larger systems, all without the environmental cost of today’s battery chemistry.
 

Flint’s technology directly supports multiple UN Sustainable Development Goals (SDGs):

• SDG 7 – Affordable, Clean Energy: Flint makes energy storage cheaper, safer, and easier to deploy, helping more communities adopt renewable power.
• SDG 9 – Industry, Innovation and Infrastructure: Our paper battery introduces a new class of sustainable energy storage that integrates with existing manufacturing processes and supports circular economy design.
• SDG 12 – Responsible Consumption and Production: The battery is made from natural, abundant materials and is fully compostable, significantly reducing electronic waste and eliminating heavy metals.7
• SDG 13 – Climate Action: By offering a safe, low-carbon alternative to lithium-based storage, Flint supports global emissions reduction goals and accelerates renewable energy adoption.

Flint has already demonstrated working prototypes, validated performance with early partners, and continues to advance toward commercial pilots.

To accelerate design, simulation, and production, Flint leverages the 3DEXPERIENCE platform across multiple domains:

• BIOVIA for materials and chemistry modeling,
• SIMULIA for performance and safety simulations,
• SOLIDWORKS for flexible battery design,
• ENOVIA for lifecycle and project management,
• DELMIA for scaling production lines efficiently.

Flint thrives on collaboration. The team brings together experts in electrochemistry, materials science, product design, and systems engineering to turn ideas into real-world solutions.

Externally, they work with partners across consumer electronics, EVs, aerospace, smart packaging, toys, and grid-level storage to commercialize our technology and accelerate the global shift to clean energy.

Through its engagement with the 3DEXPERIENCE Lab ecosystem, Flint connects with a global network of innovators who share a collective mission to drive sustainable progress.
