LONDON — Nexeon Ltd. (Abingdon, England), a company formed in 2005 to commercialize battery research conducted at Imperial College in London, has received an investment of £40 million (about $65 million) to help it pioneer the use of silicon anodes in place of carbon anodes in lithium-ion rechargeable batteries.
The Series C investment in the company was led by Imperial Innovations Group and included Invesco Perpetual; both are existing investors in the company.
Nexeon, which was looking at in intellectual property licensing business model, said it would use the money to establish a manufacturing facility that would be capable of producing around 250 tonnes of silicon anode material per year. The company did not state where the manufacturing plant would be located, how soon it could be up and running or how many people would work there.
Use of silicon anodes in lithium-ion batteries produces higher energy density can offer longer time between charges, or a smaller size battery and less weight for the same charge and performance, the company said.
The latest funding brings the total raised by Nexeon to £55 million (about $90 million).
Nexeon said is engaged with global companies in the fields of consumer electronics and automotive transport. Nexeon chairman Paul Atherton, who founded the company in 2005 with Professor Mino Green of Imperial College, said the latest funding would allow Nexeon to build the first of a series of manufacturing plants.

I have to say that I hope that this technology works, since it has promise to double the capacity of Lithium batteries. I'm curious to see if the technology is robust in shock sensitive enviroments

Doubling the capacity sounds too good to be true. Is there any study to support the claim? If the claim is true, I assume there is a couple of patent pending. Anyone can point me to the patents?

This definitely looks like promising technology. Lets hope this product will be released to market soon, because most of the products available currently in market are power hungry. This might give good batter life time.

Pretty cool technology and $65M investment is big enough to fund it, good luck guys, we need this technology to be even more portable. The gains are due to the following chemical reaction:
At the carbon anode: 6C + Li+ + e- 372 mAh/g
At the silicon anode: 4Si + 15Li+ + 15e- 3580 mAh/g

What fraction of a Lithium Ion battery weight is represented by the anode? If the facility will be capable of producing around 250 tonnes of silicon anode material per year, what volume of batteries do they anticipate producing? (for example, a Lithium Ion PHEV car battery can weigh 120 kg total)
