How our technology is changing the game

Our designs bring together the cutting edge chemistry and mechanical engineering to unlock a host of benefits.

Through improved energy density, decreased resistance and faster charging times, our technology is shifting the benchmark for cell design.

The simplicity of our design enables us to reduce costs across the board, from the materials required to the efficiency and number of parts.

Our design is a drop-in solution for all chemistries opening up game-changing possibilities to maximise the performance of your cells.

Our process

We believe in keeping things simple.

Our end-to-end process of design, prototyping and testing combines the best of chemistry and mechanical engineering to develop cutting-edge cells for mass production.

Our founders

Sam Alexander

Sam is a chemist with a Ph.D. in materials chemistry from University College London.

He has spent over a decade working on the industrialisation of Lithium-ion cell technology. He worked initially on cathode material development and scale-up at Johnson Matthey. After which he moved to Dyson and focussed on the industrialisation of solid-state cells. Prior to founding Celltris, he built and ran cell design and development programmes at Britishvolt.

Ian Hunt

Ian is a mechanical engineer with a Ph.D. in battery thermal management from Imperial College London.

He has spent his career working on battery development, starting with cell research at Dyson to pack development at McMurtry automotive. Prior to founding Celltris, he was Head of Cell Design at Britishvolt responsible for all aspects of cell design, linking materials, cell chemistry, mechanical design and engineering.
