The researchers are collaborating with LG Chem in developing a silicon anode that can absorb more lithium during charging which in effect will increase its storage capacity. The batteries using these nanotubules are expected to hit the market in three years time.

The knowledge about silicon anodes having this property has been known for quite a while but they are improving on the technology to avoid faulty developments before which led to cracks on the lithium ion batteries when charged. The new design provides better spacing for the ions to interact resulting to less mechanical strain.

On another development, experts from the Pacific Northwest National Laboratory found out that we can use Titanium Oxide, a rare earth metal which can make current lithium ion batteries perform better. The titanium oxide can not do it on its own so it was used with grapheme, a lattice of carbon components first discovered in 2004.

Graphene has been used in integrated circuits and other electronic components because of its high flexibility and conductivity. It is also less prone to extreme heat up compared to other carbon based components.

The grapheme in tandem with titanium oxide can help lower the prices of lithium ion batteries used for electric vehicles and hybrids.

The batteries have yet to be demonstrated to the public but EEStor promises that it will present the laboratory certification and produce a unit so the public can see this month. The information about the research has been tightly sealed with insiders for almost a decade now.

The barium-based EESUs are said to have better power density and energy than the lithium ion batteries we know today. They are also cheaper to make and has lifetime functionality as claimed.

On the other side of the story, the proposal of ZENN Motors was coursed to the U.S. DOE through Zenn America, a subsidiary of the Canadian company. A multi-million dollar funding is being sought for to support research efforts and construction of a development facility for small electric cars.

Law makers are set to meet with representatives from Zenn and see the feasibility of the request submitted to DOE. They seem to be interested with the details of the technology being developed and how it will impact the industry, and how it will help Americans who are in need of employment.

The department may reach a decision by the end of September following the release of lab certification for the EESU technology.
