Day lithium ion batteries have some form of lithium metal oxide positive electrode, a carbon material negative electrode and an electrolyte for transporting charge.
Sekisui Chemical replace the carbon material to a silicon based material. The potential of silicon has indeed long been known, but the material has proven to be difficult to master in the battery context.
The company has also developed a new electrolyte is solid, like today. Thus it is possible to increase production rates up to ten times when you do not have the filling operation, writes the Nikkei. If we look instead at the energy content would cost for the same capacity could fall by 60 percent to $ 290 per kilowatt hour.According to Sekisui Chemical becomes thus possible to manufacture electric cars in terms of price is in the same district as gasoline or diesel vehicles.
The battery is also reported safe. It bears punctured or crushed without fire. However, there is no data on how fast it can charge the battery or how many charge cycles it can handle.
A prototype on show at Eco-Products 2013 in Tokyo last week, 200 cm long, 30 cm wide and has a thickness of 0,3 to 5 mm thick. The cells can then be rolled, stacked or tailored appropriately to fit the space available to them. The first prototypes will find arrive next summer, and the company expects to kick off volume production in 2015.
