Slashing the cost of energy storage

Significant cell cost reductions without redeveloping chemistry

How our technology is changing the game

Our prismatic lid and terminal design is 50% cheaper than existing solutions saving over 6$/kWh and enables fast charge.

Over 50% cheaper than existing solutions. This lid saves over 6$/kWh on a 40Ah prismatic cell. All our costing has been externally validated.

Current lid solutions can be in excess of 15 components! We've reduced this to just 6. Not only that it's over 3 mm thinner so we can squeeze in more active material.

We've designed with fast charge in mind. We can get over 500A through these terminals with minimal heat rise.

We believe in keeping things simple.

We want to work openly with partners to develop our products. Samples available now.

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.

Let’s talk

We’re always on the lookout for great partners to collaborate with. So, whatever your engineering challenge, we’d love to hear from you.
