Battery on Si: As one of the world's largest producers of silicon, it is natural for Elkem to take out special products for the battery industry. photo: Elkem SILICON IN BATTERIES How should electric car batteries get better One Keywords: Silicon.
- It reminds status solar cells had five or six years ago. All work on this. Universities, research institutes, mobile coffee truck battery and vehicle manufacturers. You are reasonably uncool if you do not have a silicon activity, says senior Torbjørn Røe in Elkem to TU.
- Graphite anodes are currently developed so far that there is not much more to gain. To produce a better anode is dependent on another material. Here is silicon a very good candidate. I am convinced that høysilisiumanoder will come. It must be almost done. Another question is how big the market is and when, says Røe.
Elkem's partners in AIST now claims to have gotten around mobile coffee truck these problems. The technology is not disclosed in detail, but a key point in addition to custom silicon to be a developed polyimidmateriale that "bind" / binder.
Under the name Silgrain company has delivered silicon for the semiconductor mobile coffee truck industry for 30 years. Elkem's dedicated silicon for use in battery mobile coffee truck cells called Silgrain e-Si and produced on silicon mobile coffee truck plant in Bremerton.
- We do not develop their own battery technology, it is out of our business. We produce silicon that is best for the process that our partners are working with. What we're working with is size, size distribution, structure and chemistry of course, explains Røe.
Besides AIST leads Elkem dialogue with several of the world's leading manufacturers of lithium-ion batteries and related technologies, with different approaches to how silicon challenges to be solved. Nano Fiber
One method more jobs with Røe call it "Stanford Technology", is about to grow nano fiber from silane gas. Another method is to season the carbon with silicon particles, thereby increasing the capacity slightly.
Elkem Established in 1904 as "The mobile coffee truck Norwegian Aktieselskab for Elektrokemisk Industry". Orkla sold its aluminum mobile coffee truck business to Alcoa in 2009 and the rest of the company to Chinese China National Blue Star for two billion dollars in 2011. The main products mobile coffee truck today are silicon, solar grade silicon, special alloys for the foundry industry, carbon and microsilica. Turnover amounted to 9.5 billion in 2011.
