Breathe Design
Cell design software.
More informed design decisions.
The cell design process lacks critical insights.
Today’s battery cell design process is slow, fragmented, and heavily reliant on trial-and-error. Design teams often work in silos, relying on manual calculations, spreadsheets, or black-box models with limited visibility into how changes impact performance.
Simulating new cell designs in a system context is complex, requiring custom modelling, high expertise, and time-consuming validation. As a result, development cycles drag on, collaboration with suppliers is inefficient, and critical decisions are made without full understanding of trade-offs - leading to missed performance targets, increased costs, and slower innovation.
Remove the barrier between system and cell design.
Breathe Design is a powerful, API-delivered battery cell design and simulation platform that enables fast, flexible development - from first concept through to system-level integration.
With built-in KPI prediction, ageing analysis, and ready-to-use workbooks, it lets battery engineering teams evaluate and compare designs rapidly, simulate performance in real-world conditions, and collaborate more effectively with cell suppliers.
By linking design choices to performance outcomes, Breathe Design helps you reduce development time, cut costs, and build better batteries, faster. An R&D production line at your fingertips, in as little as 4-weeks.
Why Breathe Design?
Make design decisions that drive performance improvements
Directly link cell performance to design parameters like electrode thickness, porosity, and N/P ratio, so you can understand the ‘why’ behind performance outcomes. Breathe Design helps you prioritise the changes that actually move the needle, enabling faster iterations, fewer prototypes, and better-performing cells -delivering time and cost savings across the development cycle.
Enable smarter, more informed collaboration with cell suppliers
Breathe Design gives you the insights you need to ask the right questions - and to push for changes that matter. By linking performance outcomes to design parameters, you can engage with suppliers more effectively - whether it’s refining requirements, comparing proposals, or co-developing custom cells. Move faster, reduce back-and-forth, and get the cells you actually need.
Instantly integrate new cell designs into your battery system
Breathe Design generates ready-to-use models from your cell designs, enabling seamless system-level simulation. Evaluate how your redesigned cells perform under your exact operating conditions - thermal environment, power profile, fast-charging demands, and more - without waiting for physical prototypes.
How it works
Breathe Design is physics-based desktop cell design software. Its physics-based architecture helps you go from design parameters that matter to virtual cell models that help you evaluate system level simulations.
The design parameters include material choices, electrode structure, cell layer components, cell format and the electrolyte system, which then get constructed into a consistent battery.
Predict static KPIs - even from a blank sheet
Get instant predictions of static KPIs for every design - no coding required.
Whether you're starting fresh or refining an idea, you can create, customise, and save designs for easy comparison - focusing on what matters to you.
Evaluate the long-term performance of redesigned cells
Key features
See how your design choices affect cell ageing.
With Breathe Design, you can simulate degradation using inputs like loss of lithium inventory (LLI) and loss of active material (LAM), helping you screen and compare aged performance early in the design process, before you build a single prototype.
Accelarate battery design with API access
Our powerful design model is delivered via API, giving you instant access from any coding environment.
With ready-to-use workbooks included, you can hit the ground running - no setup delays, no steep learning curve. Whether you're rapidly prototyping or building a full optimisation flow, our tools offer flexibility to customise every step. Fast starts, seamless integration, and complete control.
Redesign and refine existing cells with confidence
Easily explore how changes to key design parameters like electrode thickness, porosity, N/P ratio, and cell geometry impact performance.
Our tools let you fine-tune your cell designs to better align with your specific targets, helping you make smarter, faster decisions at every stage of development.
Use design to investigate quality variation
Use Breathe Design to explore how manufacturing variability, such as differences in electrode thickness, porosity, or material properties, affects cell performance.
By simulating a range of parameter values, you can assess the sensitivity of your design to real-world quality variation, identify critical tolerances, and build more robust cells with fewer surprises in production.
Generate virtual cells for system-level simulation
Turn your candidate cell designs into physics-based models ready for MATLAB and Simulink.
Simulate real-world performance in your specific system context—test runtime under your thermal conditions, evaluate fast-charging potential, or explore thermal control strategies. Confidently predict how your cell will behave before it ever hits the lab.
