CellForge gives Claude and ChatGPT a real battery-design brain: cited electrochemistry, physics simulation, and safety-gated build guides — from the materials you can actually get, wherever you are.
Free for makers, forever. No app to install — it lives inside the AI you already use.
battery chemistries, every number cited — from salt-water sodium cells to LFP
real electrochemical simulation, not chatbot guesses — every result carries its error band
risk classes enforced in code: beginners are steered to safe aqueous chemistries, always
every validated community build calibrates the predictions for the next builder
Three steps between an idea and a battery on your bench.
“I want to store solar power for lights overnight — I have zinc roofing sheet, charcoal, and salt.” It asks the right questions and sizes the whole system, solar panel included.
It proposes design options, runs physics simulations, projects lifetime and cost, and renders an interactive design studio so you can see the tradeoffs.
You get a step-by-step build sheet — safety briefing first. Test your cell with a multimeter, report the numbers, and make the engine smarter for everyone.
CellForge is an MCP server — a tool your AI assistant connects to. Nothing to download.

There is nothing to buy here. Everything a maker needs is free forever, and the advanced tier is unlocked one way only: by building real batteries and sharing validated results.
Credits never expire, are never for sale, are not transferable, and will never convert to cash — by design.
Indicative launch values — tuned with the community as it grows. Every earning event requires validation first.
Test your own build with a multimeter and submit complete measurements.
Independently rebuild someone else's published design and confirm its numbers.
The first verified build of a previously untested design.
Verified regional material sourcing intel or reviewed translations.
Advanced capability for people who've proven they build.
One request, a whole map: capacity vs. temperature, rate, electrode thickness.
The engine fits its model to your measured builds.
Physics-based aging simulation over thousands of virtual cycles.
Batch evaluation of candidate electrode materials with ML interatomic potentials.
Publication-ready PDF reports and full CSV data export.
Your jobs jump the queue, with bigger batch quotas and longer simulation budgets.
Every design here was built by someone, measured with a multimeter, and validated before publication.

Pull any published design straight into your own session and keep developing it — or copy a portable design card between chats, AI clients, or servers.
