Technology

Nexeon’s unique silicon anode material unlocks the potential of silicon to deliver increased capacity without compromising lithium-ion battery cycle-life, providing lighter batteries with more power and longer lifetime between charges.

Batteries containing Nexeon’s anode material have demonstrated charge densities that compare very favourably with commercial carbone anode cells. 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 can be replaced with 3g of Nexeon’s silicon material.

The company has a broad patent 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.

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.

Market

Latest industry estimates suggest that the global Li-ion battery market is worth around $10bn and is growing fast as more electronic devices are designed and adopted by an eager public. Independent market analyst Takeshita predicts that the market for rechargeable cells will grow sixfold to $60bn by 2020.
