Newly Discovered TiO2-Coated Nanotubes Could Build Better Li-Ion Battery Electrodes

Ovidiu Sandru — Tue, 02 Feb 2010 15:29:28 +0000

Titanium dioxide (TiO2) by itself makes up a very low performance electrode, because the electrons move very slowly through it (can take years until you could fill a millimiter-thick TiO2 piece). When you reduce its thickness, though, TiO2 acts like a very good electrode.

Factory for Toshiba SCiB Batteries Planned Next Fall

Ovidiu Sandru — Wed, 07 Jan 2009 08:31:38 +0000

The SCiB batteries are a modified and improved version of the Li-Ion used currently in the industry. They will come in 24V/4.2A, that is 100W of power, and can be recharged to 90% of their capacity in 10 minutes. Compared to their older sisters, the Li-Ion, SCiBs can be recharged 5,000 to 6,000 times, not 500 to 600.

ABC News Reports the Progress of Developing the Chevy Volt

Ovidiu Sandru — Mon, 11 Aug 2008 09:20:58 +0000

There are a lot of speculations around the future Chevy Volt, the series car that it's said to revolutionize the car industry. Although there hasn't been much proof that they have the battery to power the electric-hybrid car, they're confident in their success, or at least that was wanted to be seen on this abc news video clip. Watch it. I think they're going to make it, because probably they're going to be using the EEStor technology or something equivalent, technology that has only recently been unveiled.
