Addionics unique technology enables battery development tailored for consumer electronics, micro-mobility, EVs and other applications. Addionics currently operates in two countries and works with different partners around the world.


General job description:

Addionics is searching for a battery modelling and optimisation engineer to extend its CAE team. The position consists in creating and using multi-physics models (electrochemical, thermal, mechanical) to design and optimise the next generation of lithium-ion batteries at electrode, cell and system level. The successful candidate will therefore help develop ground-breaking solutions to resolve challenges from the pore-scale level (transport processes to understand structure-performance relationships, degradation mechanisms causing energy loss and power) to the system level (Battery pack performances, thermal management, safety). This work will involve close collaborations with Senior Battery Scientists and various industrial partners as well as with Addionics’ team in Israel. The battery modeller will report to the company’s directors and work within the offices based in Central London. The holder of the position will play a vital role in planning and successfully running and completing important models which will help determine R&D directions and scaling -up.
