Silicon Nanotubules ups 10x Lithium Ion battery capacity, Graphene may help produce cheaper battery packs for EVs

The Graphene Carbon LatticeScientists from the Stanford University and Hanyang University in South Korea discovered that using silicon nanotubules in place of the graphite electrodes used by current lithium ion batteries can help increase their capacity as much as ten times.

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.
