new storage modules in a project called “Electromobility Fleet Test

The pilot project was launched by Volkswagen and Germany’s Federal Ministry for the Environment BMU together with seven other partners. The Fraunhofer Institutes for Silicon Technology ISIT in Itzehoe, Integrated Circuits IIS in Nuremberg, Dell Vostro 1510 Battery,and Integrated Systems and Device Technology IISB in Erlangen will be pooling their expertise for the next three years IBM ThinkPad R60 Battery. The researchers are developing an energy storage module based on lithium-polymer accumulator technology that is suitable for use in vehicles.

The tasks involved are distributed between the three Fraunhofer Institutes according to their skills: The ISIT experts, who have long experience in developing and manufacturing lithium accumulators, are manufacturing the cells. Their colleagues at IIS are responsible for battery management and monitoring. The scientists from IISB are contributing their know-how on power electronics components to configure the accumulator modules IBM ThinkPad T60 Battery. The development and configuration of the new energy storage module is expected to be finished by mid-2010. Volkswagen AG – the industrial partner in this project – will then carry out field trials to test the modules’ suitability for everyday use in the vehicles.

Hybrid technology combines the advantages of combustion engines and electric motors.Dell Vostro 1510 Battery, Dell Winbook N4 Battery, Dell Winbook Z1 Battery, Scientists are developing high-performance energy storage units, a prerequisite for effective hybrid motors.

A specially developed battery management system makes the energy storage device more durable and reliable. The experts are also researching into new concepts that will enable large amounts of energy to be stored in a small space. To do this Lenovo ThinkPad X60 Tablet PC Series Battery, they integrate mechanical and electrical components in a single module, devising systems for temperature control, performance data registration and high-voltage safety.

The vehicle is powered by petroleum on the freeway and by electricity in town, thus using considerably less energy. Dell Winbook N4 Battery, A hybrid propulsion system switches over to generator operation when the brakes go on, producing electric current that is temporarily stored in a battery. The electric motor uses this current when starting up. This yields tremendous savings, particularly in urban traffic.

“This module has to be able to withstand the harsh environmental conditions it will encounter in a hybrid vehicle, and above all it must guarantee high operational reliability and a long service life Lenovo ThinkPad X61 Tablet PC Series Battery,” states ISIT scientist Dr. Gerold Neumann, who coordinates the Fraunhofer activities. The researchers hope to reach this goal with new electrode materials that are kinder to the environment.

But up to now, hybrid technology has always had a storage problem. Scientists from three Fraunhofer Institutes are developing new storage modules in a project called “Electromobility Fleet Test”.

older-generation nanoflowers were not suitable for electronic products of the future

In the new study, scientists first grew clusters of carbon nanotubes, strands of pure carbon 50,000 times thinner than a human hair, that are known to have superior electrical conductivity. The scientists then deposited manganese oxide onto the nanotubes using a simple, low-cost coating technique called “electrodeposition,” resulting in nano-sized clusters that resemble tiny dandelions under an electron microscope IBM ThinkPad R50 Battery. The result was a battery system with higher energy storage capacity, longer life, and greater efficiency than conventional battery materials,Dell Vostro 1510 Battery, Dell Winbook N4 Battery, Dell Winbook Z1 Battery, the researchers say.

These “nanoflowers” may power next-generation electronic devices, say the scientists in a report scheduled for the Oct. 8 issue of ACS’ Nano Letters, a monthly journal.

Want more power and longer battery life for that cell phone, laptop, and digital music player?Dell Winbook Z1 Battery, “Flower power” may be the solution IBM ThinkPad R51 Battery. Chemists are reporting development of flower-shaped nanoparticles with superior electronic performance than conventional battery materials.

Gaoping Cao and colleagues point out that nanoflowers are not new. Researchers have developed various types of flower-shaped nanoparticles using different materials, including manganese oxide, the key metallic ingredient that powers conventional batteries IBM ThinkPad R52 Battery. However, older-generation nanoflowers were not suitable for electronic products of the future, which will demand more power and longer battery life, the researchers say.
