Scientists develop new materials to achieve the next car or “autologous” power
European scientists are developing a way to store and release electrical energy to the composite materials for automotive parts.
A cost of 3.4 million euros in imaginative projects of European scientists said, one day, auto body parts can also be used as a car battery.
Imperial College London, UK and its European partners, researchers are developing a way to store and release energy, and strong enough and light, can be used for automotive parts prototype material. The researchers hope that this material can be used in hybrid gasoline / electric vehicles, so that the vehicle lighter, more compact, more energy efficient, while allowing drivers to travel farther along the path without further charge.
In addition, the researchers believe that this has already been patented Imperial College of material has been used for a variety of everyday objects made of shell potential, such as mobile phones and computers, this way, they need a separate battery, and so that such devices smaller, lighter and more portable.
Department of Aeronautics at Imperial College, Dr Emile Greenhalgh said: “We feel the potential of this new technology is very exciting and we believe that the future of the car from its roof, hood, doors and even access to electricity, which will benefit from our development of new composite materials and even satellite navigation systems can receive power from its shell. “
Greenhalgh said: “The future applications of this material more than that you may have a credit card and as thin mobile phone, because it no longer requires a heavy battery, or a computer that can receive power from the laptop case , so that it can run longer without recharging. We are now still in the first phase of the project, still a long way to go, but we believe that this composite material has broad application prospects. “
In this study, the scientists plan to develop this material, so that it can be used to replace the trunk of the car’s metal chassis parts, namely, storage of the spare wheel well. The researchers said the wheel wells with composite materials instead of metal wheel wells, can provide power for the motor vehicle to reduce the number of batteries. They believe that this can be reduced to 15% of total vehicle weight, which significantly improve the performance of future hybrid cars.
Today’s hybrid vehicles, including an internal combustion engine, the driver will use it in speed, and a battery-powered electric motor, driving the car will use it. These vehicles require a lot of batteries for the electric motor, thus heavier vehicles, which means that cars will consume more energy, and the battery needs charging regularly in a short period.
The researchers said they are developing composite materials made from carbon fiber and a polymer resin, and can be faster than conventional batteries store and release large amounts of electricity.
In addition, this material does not use chemical processes, so that it can be faster than traditional battery charging. In addition, the charging process will not cause nearly the aging of composite materials, because it does not involve chemical reactions, while conventional batteries will be in use for some time after the aging.
The researchers said that this material can be inserted in the hybrid vehicle power supply on the domestic charge. They are also exploring other options charging methods, such as recycling energy generated when braking car.
In the first phase of the study, the scientists plan to further develop its composite materials, so that it can store more energy. The team will be through the development of carbon fiber surface of carbon nanotubes to improve the mechanical properties of this material, which will increase the material’s surface area, improve its capacity to store more energy. They also plan to explore in the industrial-level production of such composite materials the most effective way.
Organic photovoltaic cell efficiency to new highs
Organic photovoltaic (Organic photovoltaics, referred to as OPV) developer Solarmer Energy, Inc. has recently announced its new high cell efficiency, the conversion rate of up to 8.13% by the National Renewable Energy Laboratory (NREL) certification. Last December, Solarmer company has announced that its organic photovoltaic plastic similar products obtained the highest conversion rate of 7.9%. Said, more than 8% of the organic photovoltaic cell conversion rate for that industry is an insurmountable psychological barrier. With the development of the company can achieve higher conversion rate of new polymer to obtain the records.
Solarmer president Dr. Xie Yongsheng, said: “This proves that OPV technology is expected to become cost-effective and competitive technologies and we became the first breakthrough for the conversion rate of 8% of companies are very proud of the company is willing to expand cooperation with other products technology, packaging and other companies with expertise in the field of cooperation between the OPV technology to market together our company’s next goal is to get in before the end of 2011, 10% conversion rate. “
Obama battle “selling” battery
U.S. President Barack Obama is scheduled to ・ 15 speech in Michigan, called for business investment and production plug-in hybrid car batteries, said the industry will become the highlight of the U.S. economic recovery.
Obama is scheduled to fly on the same day Holland, Michigan City, participated in a groundbreaking ceremony for a battery factory.
The facility will be GM’s Chevrolet “Volt” series and the Ford Motor Company “Fox” series hybrid battery production.
The federal government is expected to 2011, this project can contribute plug-in hybrid car batteries to increase annual production to 50 000 in 2014 to reach 500,000.
White House spokesman Robert Gibbs ・ 14, said: “We intend to produce these products in the U.S. (electric vehicles and batteries), we create jobs for Americans.”
Friends called battery recycling to protect the environment
With wireless technology, lower prices, more and more popular wireless products. But because the power supply for technical reasons, the battery must be equipped with wireless mouse, with the increased use of battery recycling to the fore, some enthusiastic early users called trip battery recycling system, let’s take a look at our wonderful friends with the analysis.
Pollution and waste battery treatment has become the social focus of most environmental concern. State Environmental Protection Administration of Science, Technology and concerned that with our type of battery, production and use continues to expand, the number and types of used batteries has also increased. Used batteries contain mercury, lead, cadmium, nickel and other heavy metals and acid, alkali and other electrolyte solution, on the human body and the environment have different degrees of harm. It is understood that one of the ecological environment on human health and the harmful, included in the list of hazardous waste control batteries are: mercury batteries, mainly mercury oxide battery; lead-acid batteries; cadmium batteries, nickel-cadmium batteries primarily.
Today, e-waste disposal has been the focus of public attention, the majority of users are also welcome to offer advice and offer words, a better environment for our contribution to a force.
