Britishvolt announces roadmap for development of 4690 tailored battery cell technology for high performance EVs

Battery technology pioneer Britishvolt has a development roadmap for larger format, 4690, high-performance lithium-ion advanced cell technologies, starting with digital-twin modelling before being transferred to EAS, and subsequently to its Hams Hall scale-up facilities in the UK, for prototype and production.

Orral Nadjari, Founder, CEO, Britishvolt, said: “Britishvolt understands the importance of larger format cells, which is why our recent acquisition of EAS, of which the importance needs to be fully grasped by the market, and our scale-up facility in the Midlands will help us deliver 4690 cells that our customers require. Critically, we will be able to build these game-changing cells in a truly sustainable, low carbon way. We start with digital twin/simulation modelling, exactly the same way we did with our 21700 cell development, and then move on to physical prototyping.”

“This improves efficiency, reduces waste, lowers costs and makes us leaner and more agile. We can also tailor the length of the cell to suit specific applications. This is a unique Britishvolt proposition that will also help anchor the UK as a global battery leader and home to leading battery innovation. We are helping reindustrialise the UK.”

The 4690 cell pathway is in development at Britishvolt, where the company is leveraging its digital-twin simulation and modelling capabilities to drive engineering and bring technology to market quicker and more efficiently.

The use of digital twin, via our simulation and modelling capabilities, provides Britishvolt with analytical data and tools, coupled with our manufacturing expertise, to effectively tailor the 4690 cell.

This customization can be in aspects including the variation of dimension, i.e. to shorten or increase the cell length against the 4690 format, in order to maximise performance and system integration delivering the product our end customers require.

The battery technology pioneer has cell chemistry development and optimisation pathways underway, coupled to cell mechanical design engineering, which builds upon the expertise in prototyping and cell design at EAS and is linked to development programmes with Britishvolt’s cell manufacturing equipment suppliers.
