Nexeon is developing materials for the next generation of lithium-ion rechargeable batteries.


Nexeon’s unique silicon anode material unlocks the potential of silicon to deliver increased capacity and extending cycle-life, providing lighter lithium-ion battery batteries with more power and longer lifetime between charges.

Batteries containing Nexeon’s anode material have demonstrated cell capacity can be increased by 30-40% using a standard industry cathode. As well as capacity benefits, Nexeon’s materials can also offer a reduction in battery size. A commercially available carbon-anode 2.6 Ah ‘18650’ Li-ion cell uses around 10g of carbon anode material; this carbon could be replaced with 3g of Nexeon’s silicon material.

The company has a broad intellectual property portfolio relating to high-aspect ratio silicon materials and the use of such materials in lithium-ion batteries.

Nexeon targets the automotive and consumer electronics sectors as early adopters of its technology and has established relationships with global manufacturers in these sectors. The company is providing materials, coated anodes and cells under Material Evaluation Agreements to major battery companies, in addition to collaboration with major global OEMs to optimise its battery technology for use in electric vehicles. The company has also engaged with niche applications such as defence where energy density is the priority.

Nexeon's technology is based on work carried out by Emeritus Professor Mino Green at the Department of Electrical and Electronic Engineering at Imperial College London.

Manufacturing plant

Nexeon is based in Oxfordshire, and has recently commissioned a manufacturing facility capable of producing 20 tonnes of material per year. Nexeon also runs a fully instrumented pilot plant, allowing an accurate understanding of the processes and costs associated with making anode materials. The technology has been conceived with a 'drop-in' approach, requiring the minimum of changes to an existing Li-ion battery manufacturing operation.


Latest industry estimates suggest that the global Li-ion battery market is worth around $17bn and is growing fast as more electronic devices are designed and adopted by an eager public. Independent market analyst Avicenne predicts that the market for Li-ion cells will grow fourfold from 40 GWh to 160 GWh.
