New Nickel-Lithium Battery Has “Ultrahigh” Energy Storage Capacity

Nick Chambers — Tue, 06 Oct 2009 19:38:23 +0000

Researchers have found a way to create a battery out of Nickel and Lithium that can store more than 3.5 times the energy of lithium-ion batteries and are much safer to boot.

Lithium-ion batteries are great and all—having heralded in a new age of portable electronics and allowed for the possibility of mass-market electric cars—but they have a few major drawbacks. For instance, they have a propensity to catch fire and explode and, although they have a much better energy storage capacity than say lead-acid or nickel metal hydride (NiMH) batteries, they still weigh too much to pack more than a couple hundred miles of range into a passenger car.

Toyota and EDF Testing Plug-in Prius in UK

In an international effort, Japanese automaker Toyota and Électricité de France (EDF) are expanding their European plug-in hybrid electric vehicle (PHEV) testing program to the United Kingdom.

The trial builds on the first European PHEV testing program launched by Toyota and EDF on French roads in September 2007. The UK partnership is designed to evaluate vehicle performance within an urban environment, vehicle infrastructure requirements, and driver behaviors and expectations.

Trials started on September 10th and will continue for more than one year. Toyota’s PHEV will make its on-the-road debut as part of EDF Energy’s company fleet and will be tested by employees under every-day driving conditions. The modified plug-in Prius being tested will utilize nickel-metal hydride (NiMh) batteries, with an all-electric range of approximately 8 miles if the speed remains below 62 mph. When Toyota begins producing the plug-in Prius (expected for fleets in 2009), it will utilize superior lithium-ion batteries.

Who Might Win McCain’s Battery Competition? Part I: Firefly

Editor’s note: This post is a lead-in story to the Gas 2.0 interview with Mil Ovan, Senior Vice President and Co-founder of Firefly Energy.

Last week John McCain, the presumptive presidential nominee for the 2008 Republican ticket, suggested that a $300 million government-sponsored competition would be a good way to spur development of next generation battery technologies.

His comments generated debate in the blogosphere and around the United States. Meanwhile, Barack Obama, the presumptive presidential nominee for the Democratic ticket, called McCain’s proposal a gimmick suggesting that $300 million was not enough.

Regardless of my feelings about the proposed competition or the candidates themselves, it got me thinking about just who might win it if it were to become a reality. All that thinking led to this post, and, hopefully, to several others that will look at the most promising next generation battery technologies on the horizon.

This week I’ll start with Firefly Energy.

Firefly Energy is one of the companies that made it to my short list. Founded in 2003, they have been working on reinvigorating old-hat lead-acid battery technology in such a way that it would become brand new and cutting edge once again.

Firefly’s innovation is that they’ve taken the heavy lead plates you’d find in a classic lead-acid battery and replaced them with a light carbon-graphite microcell foam that’s been impregnated with lead.
