Aluminum could give boost to capacity, power of lithium-ion batteries

Researchers have created an electrode made of nanoparticles with a solid shell, and a "yolk" inside that can change size again and again without affecting the shell.

Supercapacitors with batteries or fuel cells: result happiness

IDTechEx interviews in Japan have established that supercapacitors across lithium-ion batteries in cars can increase range by 10% by permitting deep discharge, provided suitable batteries are used that can tolerate such a regime.

Transforming wearable devices for 3D display

Moving holograms like those used in 3D science fiction movies such as Avatar and Elysium have to date only been seen in their full glory by viewers wearing special glasses.

Beijing Tiertime Technology Co Ltd

Tiertime was formerly known as Beijing Yinhua Laser Rapid Prototyping and Mould Technology Co., Ltd., a company created by a Tsinghua Professor Yan Yongnian, who is recognized as the first person to explore 3D printing in China. Tiertime is currently the single largest manufacturer of 3D printers in China,

Flexible supercapacitor could be woven into clothes to power devices

Scientists have taken a large step toward making a fiber-like energy storage device that can be woven into clothing and power wearable medical monitors, communications equipment or other small electronics.

Samsung Electronics

The first successful ultra high transparency barrier material, which was commercialized by Vitex, was originally developed by GE in a process designed to be used for capacitor fabrication. This process is called the Polymer Multi-Layer (PML) process. It was developed in the late 1970's and early 1980's at GE's capacitor division in Hudson Falls, NY for the fabrication of multilayer, polymer/aluminum capacitors. By2011, most of the company's IP had been acquired by Samsung

Scientists invent self-healing battery electrode

Researchers have made the first battery electrode that heals itself, opening a new and potentially commercially viable path for making the next generation of lithium ion batteries for electric cars, cell phones and other devices.

Novel silicon electrodes that improve lithium-ion battery performance

Stanford University scientists have dramatically improved the performance of lithium-ion batteries by creating novel electrodes made of silicon and conducting polymer hydrogel, a spongy substance similar to the material used in soft contact lenses and other household products.

Even graphene has weak spots

Graphene, the single-atom-thick form of carbon, has become famous for its extraordinary strength. But less-than-perfect sheets of the material show unexpected weakness.

Findings could lead to better hydrogen storage

New research by a team from MIT and several other institutions analyzes the performance of a class of materials considered a promising candidate for such storage: activated carbon that incorporates a platinum catalyst, so hydrogen atoms can bond directly to the surface of carbon particles and then be released when needed.

Biofuel Cell for self-powered nanodevices

The goal of nanotechnology is to build nanodevices that are intelligent, multifunctional, exceptionally small, extremely sensitive and have low power consumption.

Chinese National Institutes sign collaboration agreement with G24i

Just three weeks after G24 Innovations (G24i) successfully launched the world's first commercial application of Dye-Sensitive Solar Cells (DSSC), the global pioneer of DSSC announced that it has signed a formal agreement with three of China's most prestigious institutes to accelerate industrial development of the technology.

Western RFID companies flock to China

China was the world's largest RFID market in 2007 on the back of the huge city card schemes and the $6 billion national ID card scheme, all now largely completed.
