A Swansea University-led initiative, known as the StamiNa project (Sustainable Transport and Affordable Mobility through Innovation in Na-ion technology), has secured vital funding from the Faraday Institution under phase two of the Ayrton Challenge on Energy Storage (ACES) R&D programme.
The project brings together a consortium of academic and industry partners, including Coventry University, Batri Ltd, AceOn Group, Strathmore University (Kenya), and the Federal University of Technology Owerri (Nigeria), to develop and deploy advanced sodium-ion battery (SIB) systems tailored for electric mobility in sub-Saharan Africa.

The project focuses on demonstrating a prototype swappable battery pack designed specifically for e-mobility, such as e-bikes, which will undergo real-world testing in Kenya and performance evaluation in Nigeria. The batteries incorporate innovative technology co-developed by Swansea University and Batri Ltd, using Prussian White cathodes and coal-derived hard carbon anodes.
This composition avoids critical minerals like cobalt and nickel, and supports a more sustainable, cost-effective production process. Moreover, the materials are synthesised in water under mild conditions, making them suitable for local manufacturing and supply chains.
Key objectives of the project include scaling up the production of active materials, refining cell assembly processes, and manufacturing multilayer pouch and cylindrical cells. These will be integrated into battery packs by AceOn Group and tested for performance, durability, and efficiency against current lithium iron phosphate (LFP) and commercial SIB alternatives.
By focusing on locally relevant solutions and sustainable production methods, the StamiNa project aims to fast-track the commercialisation of UK-developed SIB technology and foster the growth of an African-led battery ecosystem. This effort supports broader goals of clean mobility, energy access, and climate resilience across the continent.
