Warm hints: The word in this article is about 2800 words and  reading time is about 15 minutes.SummaryLithium-ion batteries can be said to be the most mature and widely used new energy sources in the world at present, such as portable electronic products like mobile phones and computers, electric vehicles, electric tools and energy storage projects. Especially the current Chinese government and other countries are investing to support the development of new energy vehicles and power battery ...
SummaryThe world's first full-size interdigitated back contact (IBC) bifacial solar module has been developed and fabricated in Singapore by the Solar Energy Research Institute of Singapore (SERIS) at the National University of Singapore (NUS) in collaboration with the International Solar Energy Research Center Konstanz, Germany (ISC Konstanz).About IBC Solar Cell ModuleThe module technology's first prototype was produced using bifacial ZEBRA IBC solar cells from ISC Konstanz with effici ...
SummaryThe process that makes gold-plated jewelry or chrome car accents is now making powerful lithium-ion batteries. It's reported in the Joural Science Advances that research at the University of Illinois, Xerion Advanced Battery Corporation and Nanjing University in China developed a method for electroplating lithium-ion battery cathodes, yielding high-quality, high-performance battery materials that could also open the door to flexible and solid-state batteries in May,2017.Paul V. Braun, ...
SummaryWe know that empty batteries are easy to recognize.However,it is much more complicated to know the charge status between full and empty.A complete new approach with ultrasound pluses offers a precise and simple method.Batteries are used in many "mobile" technologies,and that is why it is the snag in "mobile" technologies. Like smartphones,drones,or electric cars-in many cases he time between battery charges is much too short for many people. This is why it is important ...
SummaryIron-air batteries promise a considerably higher energy density than present-day lithium-ion batteries. In addition, their main constituent -- iron -- is an abundant and therefore cheap material. Scientists from Forschungszentrum Jülich are among the driving forces in the renewed research into this concept, which was discovered in the 1970s. Together with American Oak Ridge National Laboratory (ORNL), they successfully observed with nanometre precision how deposits form at the iron electr ...
SummaryThe invention of electril trucks has bring a lot of benefit for human being. An electric truck is a truck powered by electricity. For information on trucks using a combination of internal combustion engines and electric propulsion, see Hybrid electric truck. Now they are having a moment in the spotlight,however,they still have a long haul cause the costs and other limitations.Tesla Inc. plans to unveil a semi tractor-trailer this week, its first foray into trucking after more than a decad ...
Do you want a photo book incorportating the sound of the sea and  birdsong,a novel with spoken dialog? Most Children may say yes.But how to invent such a product out?Yeah,this is all made possible by loudspeaker paper and electronic concealed in the cover. Such a T-book can currently be heard at the Frankfurt Book Fair ( here the T stands for the German word Ton,means sound ).Most fairs even book fairs are already loud enough. However,the future noise level looks like to keep increasing if  ...
A New Breakthrough in Battery TechnologyThe breakthrough comes from a team of engineers led by John Goodenough, the co-inventor of the lithium-ion battery. A new discovery has come out which could pave the way for batteries to last more, and it won’t explode.The breakthrough comes from a team of engineers led by John Goodenough, the co-inventor of the lithium-ion battery which is used to power everything from smartphones to electric cars.Led by John Goodenough and a team of engineers, the co-inv ...
With the rapid increase in production of intermittent energy sources such as wind and solar, there is an increasing need for large-scale electrical energy storage systems to more efficiently match supply and demand for these renewable sources. Also, large-scale energy storage can increase the annual load factor (defined as the annual mean power divided by the maximum three-day mean power) by load leveling. Traditionally, pumped-hydro has been used for load leveling at large scale plants, but thi ...
(In a new concept for battery cathodes, nanometer-scale particles made of lithium and oxygen compounds (depicted in red and white) are embedded in a sponge-like lattice (yellow) of cobalt oxide, which keeps them stable.)Engineers from MIT propose that a new lithium-oxygen battery material could be packaged in batteries that are very similar to conventional sealed batteries yet provide much more energy for their weight.Lithium-air batteries are considered highly promising technologies for electri ...
(USC professor Sri Narayan's research focuses on the fundamental and applied aspects of electrochemical energy conversion and storage to reduce the carbon footprint of energy use and by providing energy alternatives to fossil fuel, Wednesday, June 10, 2014 in Los Angeles.)Scientists at USC have developed a water-based organic battery that is long lasting, built from cheap, eco-friendly components. The new battery -- which uses no metals or toxic materials -- is intended for use in power plan ...
(Integrated microscale flow batteries could power and cool future three-dimensional chip stacks.).Tightly packed electronic components generate a lot of heat. Tiny redox flow batteries will beneath supplying energy also dissipating the heat they produce.Researchers at ETH Zurich and IBM Research Zurich have built a tiny redox flow battery. This means that future computer chip stacks – in which individual chips are stacked like pancakes to save space and energy – could be supplied with electrical ...
Engineers at the University of Maryland have invented an entirely new kind of battery. It is bio-compatible because it produces the same kind of ion-based electrical energy used by humans and other living things.In our bodies, flowing ions (sodium, potassium and other electrolytes) are the electrical signals that power the brain and control the rhythm of the heart, the movement of muscles, and much more.In traditional batteries, the electrical energy, or current, flows in form of moving electron ...
When you hear the word battery, what do you think? Those annoying pink Duracell rabbits, the ones you have stolen from the back of the remote control or the fact that your phone’s battery may as well cease to exist because nowadays it barely lasts all of five minutes? It is a common fear in most of us, that whilst we are out having a good time your phone’s battery is quickly fading in your pocket. However, we never seem worried about the battery’s eventual lifespan, which for the record is norma ...
Researchers at Tokyo Institute of Technology have devised a low-cost approach to developing all-solid-state batteries, improving prospects for scaling up the technology for widespread use in electric vehicles, communications and other industrial applications. Ever since batteries were invented over 200 years ago, there has been a drive to improve quality and performance at reduced costs.Compared to common lithium-ion batteries that contain lithium ion conducting liquids, all-solid-state batterie ...
