Energy Storage

New nanoengineered batteries developed at Rensselaer exhibit remarkable power density, charging more than 40 times faster than today's lithium-ion batteries.

Rice University researchers have moved a step closer to creating robust, three-dimensional microbatteries that would charge faster and hold other advantages over conventional lithium-ion batteries.

A new Japanese vibration battery, which is similar in size to a pencil tip, is able to generate power from small vibrations.

Electron switch between molecules points way to new high-powered organic batteries

Angstron Materials Inc, has invented a graphene-based supercapacitor with ultra high energy density, a feature that permits storage of a significant amount of energy.

A team of researchers at the University of Maryland's A. James Clark School of Engineering and College of Agriculture and Natural Resources, brought together by Professor Reza Ghodssi, is harnessing and exploiting the "self-renewing" and "self-assembling" properties of viruses to build a new generation of small, powerful and highly efficient batteries and fuel cells.

The inaugural IDTechEx electric vehicle event in San Diego California was a great success and it will now be repeated annually in three continents.

Researchers in the US have made a graphene-based supercapacitor that can store as much energy per unit mass as nickel metal hydride batteries - but unlike batteries, it can be charged or discharged in just minutes or even seconds. The new device has a specific energy density of 85.6 Wh/kg at room temperature and 136 Wh/kg at 80 °C. These are the highest ever values for "electric double layer" supercapacitors based on carbon nanomaterials.

Infinite Power Solutions has announced that it has named former Segway Inc. executive James Norrod to the position of president and CEO of IPS, effective immediately.

Terradigm Technology is working with corporate partners to launch innovative green products that generate power through natural kinetic motion - an industry first.

Ioxus is one of only two companies worldwide with hybrid capacitor technology in general production

At IDTechEx Energy Harvesting & Storage USA 2010 Powercast Corporation, a leader in RF-based wireless power and energy harvesting technology, announced its Lifetime Power® Energy Harvesting Development Kit for Battery Charging.

Taiyo Yuden's Hybrid LIC boasts the key features of batteries (high voltage and high energy) while maintaining the traditional characteristics of capacitors (rapid charge/discharge, high durability, safety and environmental friendliness).

The major growth in electric buses is in free running versions which cost $50,000 to $500,000 and can usually be deployed without infrastructure along the route. The larger electric buses tend to be hybrid to get the range: smaller ones tend to be pure electric. The IDTechEx report, "Electric Vehicles 2010-2020" estimates that there are about 480,000 buses in the world - mostly small ones - with about 135,000 being bought each year as the fleets grow. Although only 12% of these new buses are electric, penetration is increasing and there is a multibillion dollar market awaiting.

At the unique event Future of Electric Vehicles 7-8 December in San Jose California , the market for all electric vehicles in the world and specifically East Asia will be forecasted by type.

Today's consumer electronics are reliant on lithium-ion batteries, but new DARPA-funded research hopes to develop tiny batteries, no bigger than a grain of sand.
