Silicon Electrode Doubles Rechargeable Battery Capacity

Benji Jerew — Tue, 17 Jun 2014 01:19:19 +0000

Rechargeable battery technology has a lot of demands to meet, but a recent development more than doubles current capacities. To be considered acceptable for today’s mobile devices, whether they be smartphones, laptops, electric vehicles, or grid backup, a rechargeable battery needs to cover three basics. A good rechargeable battery has to be energy dense, be […]

BMW Forecasts Double Electric Vehicle Range in Five Years

Benji Jerew — Mon, 01 Jul 2013 18:10:20 +0000

Recently, BMW announced its vision for the future of electric vehicles that, in the next five years or so, we could see double the range. In the 1950s, transportation prognosticators envisioned cities in the sky and flying cars. Here we are, half-a century later, still stuck on the ground. Electric vehicle manufacturer Tesla Motors currently […]

Battery Technology Accelerator Started by CalCharge and San José University

Benji Jerew — Tue, 19 Feb 2013 16:54:34 +0000

Rechargeable battery technology development isn’t dead by any means, and still needs plenty of research to perfect and improve it. There are perhaps billions of people on the planet who have a great idea on how to make something better. Tinkers, inventors, researchers, and scientists have all this in common, but to get an idea out to […]

Crushed Porous Silicon Anode Batteries Overcome Classic Limitations

Janina Lazo-Cruz — Fri, 02 Nov 2012 14:46:14 +0000

Researchers from Rice University, led by Lisa Biswali, have developed a cost-effective silicon anode (negative electrode) for rechargeable batteries that easily attains 600 charge-discharge cycles at 1,000 milliamp-hours per gram (mAh/g), which is only a third of its theoretical capacity, but almost thrice the current capacity of graphite anodes. In search of a better replacement […]

Sodium Could Be The Next Best Thing For Rechargeable Batteries

Mila Luleva — Fri, 19 Oct 2012 17:54:19 +0000

With lithium batteries being the most desirable mean for powering devices, it is inevitable that their main disadvantage is highlighted. The element that powers them is considerably expensive and it is expected that the price will rise with the increasing number of electric vehicles on the market. Hence, scientists from around the world have been […]

German Researchers Dramatically Improve Electrolyte Filling Time in Batteries, Reduce Costs

Ovidiu Sandru — Mon, 17 Oct 2011 19:17:12 +0000

A discovery made by researchers at the Karlsruhe Institute of Technology (KIT) can eventually make lithium ion batteries cheaper by improving a key process that currently takes a lot of time to complete: filling the batteries with liquid electrolyte. The porous electrodes inside modern rechargeable batteries have to be properly filled with liquid electrolyte. Actually, […]

24M's Liquid Battery Can Be Filled With Sludgy Electrodes, Cuts Price in Half

Ovidiu Sandru — Mon, 30 May 2011 17:19:00 +0000

24M, a spin-off from battery maker A123 has published a paper which describes a new type of battery that would outperform any existing lithium ion unit designed for electric vehicles. Today's lithium batteries are bulky and heavy just because there's a lot of extra material in them that doesn't have anything with the storage of energy, but merely with supporting the active "ingredients."

Lithium Air Batteries Find That Gold-Platinum Catalyst Increases Their Efficiency and Lifetime

Ovidiu Sandru — Wed, 09 Jun 2010 16:49:18 +0000

MIT researchers have just discovered an alloy that, if used as a catalyst, makes lithium-air batteries more efficient. This type of battery works by reacting the metal lithium with the oxygen from the air, and is very efficient at storing high amounts of energy (three times more than lithium ion). The industry awaits the development of lithium air batteries so they can be used in future electric cars.

Knut Karlsen`s Self-Rechargeable Solar Batteries

Ovidiu Sandru — Mon, 23 Feb 2009 07:09:14 +0000

I have always liked the idea of rechargeable batteries, because they only cost a fraction of what they're worth as normal batteries, but now I see a different innovation that I had never thought of, even it was obvious: putting solar cells onto the rechargeable battery, and having it charged for free, and most importantly, anywhere!
