Without them, electric cars aren't viable.

They need a range of at least 300km, curently it stands at 150km - best case scenario. There's hope.

A project led by advanced UK battery manufacturer Axeon and co-funded by the Technology Strategy Board has been successful in developing a new battery for use in electric cars that offers over a 35 per cent improvement in range compared to existing technologies, for the same weight.

In 2009, the Technology Strategy Board awarded over 680,000 of funding to the consortium led by Axeon (bringing the total project funding to over 1.3m), with the aim of developing an innovative high energy/density battery system for an emission-free electric vehicle.

The battery uses Nickel Cobalt Manganese (NCM) electrochemistry which theoretically requires 50 per cent less volume and 30 per cent less mass when compared to Lithium Iron Phosphate chemistry.

The project included subjecting the battery to automotive environmental validation testing and the learning from this has been incorporated into the final design to ensure a robust solution.

Axeon and its partners, Ricardo and Allied Vehicles, have now delivered an advanced demonstrator that has been deployed into a test vehicle, increasing its range, functionality and performance.
