A previous post discussed advanced battery maker Electrovaya’s lithium ion polymer technology, which the company says provides faster, more efficient transport of lithium, and therefore greater energy density.

Several years ago, Electrovaya partnered with Tata (more…)

This proposal involves a simple synergy of government incentives and distributed energy storage applications. But first, I’d like to briefly discuss some of the issues that this solution addresses.

The Issues

Climate Change (more…)

What do the cleantech companies ElectronVault, SEaB Energy, and BlackGold Biofuels all have in common? Female executives at or near the top of the food chain.

Marissa Mayer, the recently appointed CEO of Yahoo, drew a lot of attention because of her gender and the fact that she was pregnant when (more…)

Battery technology keeps improving in terms of density and storage, but how about changing the very form in it which a battery is presented? This is what researchers at Rice University in Texas have done with the creation of a paintable battery solution that reinvents the whole concept. (more…)

The promising but financially troubled A123 Systems lithium-ion battery maker announced yesterday that it has made a significant advance in battery technology that will enable electric car batteries to last longer and cost less.

A123 has been a leader in the race to develop (more…)

It is not surprising how the electric vehicle growth story mirrors mobile phone growth but about 30 years later. It was in 1973, when Martin Cooper, a Motorola researcher made the first analog phone call using a heavy prototype device. Then came the first generation of mobile cell sites, with ability to transfer calls from one site to next in 1979. (more…)

About one fifth of the world’s population lacks access to electricity. It is one of biggest economic obstacles for people in developing countries, but one that could mean opportunities for a clean energy beginning with alternative energy. (more…)

Announced on February 14, the Obama administration’s Department of Energy (DOE) budget recommendation is a big valentine to those working on developing batteries for electric vehicles.

As we said last year, the current administration has focused the majority of its vehicle technologies (more…)

Greentech Media recently reported that Southern California electric vehicle startup Coda Automotive (Coda) launched a battery business called Coda Energy, which will enter the grid-scale energy storage market.

Coda’s patent portfolio offers a window into the (more…)

Electric vehicles offer a green transportation alternative. There have been great advances in the sector after the launch of popular models such as Nissan’s LEAF, which recently won the car the of year award at the Tokyo Motor Show.

However, electric car battery technology is one (more…)
