A New Idea for the Electro Mechanical Battery

February 7, 2012 | Leave a Comment

Carl Peart of New Mexico has a very different take on the electro mechanical battery (EMB) – solve the inherent problems of friction with air and bearings – by using them in orbital power stations.  No air or gravity, only centrifugal forces for drag. An EMB (a technical description of a flywheel) stores energy through [...]

IBM Says It Now Has a Working Lithium Air Battery

January 10, 2012 | 4 Comments

Physicist Winfried Wilcke working at IBM’s Almaden laboratories, based in San Jose, California in a report by Duncan Graham-Rowe in NewScientist allows that IBM’s Battery 500 project to find an air battery solution for electric vehicles (EVs), has found a starting solution. The assertion now is IBM believes it has solved a fundamental problem that [...]

The Case For Better and Cheaper Batteries

December 30, 2011 | 1 Comment

Nothing is more persuasive than consumer expectations for determining planning and investment.  To help with that Pike Research conducted a web-based survey of 1,051 U.S. consumers in the fall of 2011 using a nationally representative and demographically balanced sample to consumer demand, preferences, and price sensitivity for plug-in electric vehicles (PEVs) and electric vehicle charging [...]

40,000 Battery Charging Cycles

November 25, 2011 | 4 Comments

Those lithium-ion batteries we’ve come to appreciate in cell phones and other small portable electronics don’t last as long as one would like – the full charge shrinks a little with each recharge. Stanford researchers have developed part of a new dream battery with a new electrode that employs crystalline nanoparticles of a copper compound.  [...]

Halfway to the Ultimate Lithium Battery

November 16, 2011 | 1 Comment

Northwestern University engineers show in the journal Advanced Energy Materials they have developed technology that could hugely improve lithium batteries.  The new anode technology suggests a cellphone battery might recharge in 15 minutes and last ten times longer. The scientists combined two chemical engineering approaches to address two major battery limitations — energy capacity and [...]

A Battery For The Grid

October 10, 2011 | Leave a Comment

Aquion Energy in Pittsburgh uses the simple chemistry of water-based electrolyte and abundant materials such as sodium and manganese for a grid scale battery that is expected to cost $300 for a kilowatt-hour of storage capacity, less than a third of what it would cost to use lithium-ion batteries.  Third-party tests have shown that Aquion’s [...]

More Than Doubling the Power In a Capacitor

October 3, 2011 | 2 Comments

With super and ultra capacitors and EEStor still far too expensive, not available if not simply vapor – capacitors need something to perk up the storage market. Dr.  Xie Xian Ning from the National University of Singapore’s (NUS) Nanoscience and Nanotechnology Initiative has developed the world’s first energy-storage membrane promising greater cost-effectiveness in delivering energy.

The Not a Battery or Capacitor Storage Device Comes to Market

September 22, 2011 | Leave a Comment

An electric double layer energy storage device manufacturing line by Murata Manufacturing Co. Ltd. in Japan has started up.  The electric double layer energy device has an equivalent series resistance as low as several tens of milliohms. The devices will come in two models. One is 1.5mm thick and has an instantaneous maximum allowable voltage [...]
