The tiny battery created by Huang and co-workers consists of a single tin oxide nanowire anode 100 nanometers in diameter and 10 micrometers long, a bulk lithium cobalt oxide cathode three millimeters long, and an ionic liquid electrolyte. The device offers the ability to directly observe change in atomic structure during charging and discharging of the individual "trees."

a battery that is "charged" by applying a large magnetic field to nano-magnets in a device called a magnetic tunnel junction (MTJ). The new technology is a step towards the creation of computer hard drives with no moving parts, which would be much faster, less expensive and use less energy than current ones. In the future, the new battery could be developed to power cars. The study will be published in an upcoming issue of Nature and is available in an online advance publication of the journal.

"Lithium Energy Japan" to produce large capacity and high performance lithium-ion batteries. ...automated mass production lines within a 7000m2 facility at GS Yuasa's Kyoto's head office plant, capable of manufacturing 200,000 cells per year. Operations were slated to commence by 2009.

Subaru has released a second generation battery-electric vehicle, the G4e (for "Good 4 earth"). The 5-seater has a maintenance-free 65-kilowatt electric motor, and features high energy-density vanadium enhanced lithium-ion batteries, which give the G4e a 124 mile (200km) range from a charge (more than double the first generation R1e's range, previous post) and using a quick-charger it can be charged to 80% in only 15 minutes

Eon UK is developing a giant battery designed to store electricity generated by wind farms and solar panels. Scientists at the energy group's technology centre in Nottingham aim to build a large-scale prototype that would be able to store one megawatt of electricity for four hours - the equivalent to 10m AA batteries and the same size as four articulated lorry containers.

The new battery relies on an innovative architecture called a semi-solid flow cell, in which solid particles are suspended in a carrier liquid and pumped through the system. In this design, the battery's active components - the positive and negative electrodes, or cathodes and anodes - are composed of particles suspended in a liquid electrolyte. These two different suspensions are pumped through systems separated by a filter, such as a thin porous membrane.

"A Malaysian company called ETI Tech Corporation Bhd has developed the world's first lithium-polymer battery system for solar-powered homes."

"What if surplus renewable energy could be stored as computation instead? That's the thinking behind "information batteries," a new system proposed by Raghavan and Jennifer Switzer, a Ph.D. student from UC San Diego, published recently in the ACM Energy Informatics Review."
