Pioneering the Next Generation of Battery Simulation

An ultra-fast Newman-model solver

DandeLiion solves electrochemical models of planar lithium-ion cells, and thermal-electrochemical models of three-dimensional composite pouch cells, at a speed and scale suited to real engineering work.

It implements full Doyle–Fuller–Newman porous-electrode theory, the family of models first developed in the 1990s and known since as Newman models. Nonlinear diffusivity is carried in both the solid and the electrolyte phases, and thermal transport, electrochemistry and degradation are coupled together and solved rather than approximated.

Because the solver works in fully three-dimensional geometry, the same physics that describes a single cell also describes a large format cell or a complete module. Degradation mechanisms such as SEI growth and lithium plating form part of that solution instead of being applied afterwards as a post-processing step.

Built for industry, too

DandeLiion Technologies Ltd is spinning out from the Universities of Southampton and Portsmouth, founded by the research team that wrote the solver, and is a Faraday Institution Entrepreneurial Fellow.

In late 2023 DandeLiion entered a technology licensing agreement with About:Energy, a UK innovator in battery parameterisation, and the modelling software has since been integrated into their Voltt platform. For commercial enquiries, please get in touch.
