UK Energy Storage Startups Take Aim At EV Battery Market

Lithium-ion is the gold standard for chemical energy storage, but a pair of UK companies have been working on alternatives that could knock down the cost of electric vehicles and knock Li-ion out of the running. The two companies, Oxis Energy and Faradion, caught the eye of the American Chemical Society, which just gave them a huge write-up in its Chemical & Engineering News publication, so lets take a look and see whats up.

We were just noticing Oxis Energy, too. Earlier this summer, Oxis announced that it will be ready to bring its lithium-sulfur (Li-S) battery to market next year, and it also entered into a partnership with the home and commercial energy storage installer Anesco.

Writing for Chemical & Engineering News yesterday, Alex Scott brings us up to date. Oxis plans to double what any lithium-ion [Li-ion] battery can deliver within about four years, bringing the energy density of its battery cells to 500 Wh per kilogram. The near-term goal, according to the companys website, is 400.

If Oxis can succeed in using half the material to provide the same performance as Li-ion, that would bring down the cost of an electric vehicle significantly.

The company is aiming for a cost of $125 per kWh (kilowatt-hour) in the near term. Scott does the math and arrives at a cost of $10,000 for an electric vehicle battery with a capacity of 80 kWh.
