Proposed design is easy to produce, low-cost, flexible and more efficient than previously proposed paper-based batteries. The batteries of the future may be made out of paper. Researchers at Binghamton University, State University at New York have created a biodegradable, paper-based battery that is more efficient than previously possible.

For years, there has been excitement in the scientific community about the possibility of paper-based batteries as an eco-friendly alternative...

The batteries were made by stacking various layers via thin-film deposition methods. The LNMO/Li3PO4 interface showed spontaneous migration of Li ions and had an unprecedentedly low resistance.

Scientists at Tokyo Institute of Technology have addressed one of the major disadvantages of all-solid-state batteries by developing batteries with a low resistance at their electrode/solid electrolyte interface. The fabricated batteries showed excellent electrochemical properties that greatly surpass those of traditional and ubiquitous Li-ion batteries; thereby, demonstrating the promise of all-solid-state battery technology and its potential to revolutionize portable electronics.

Many consumers are familiar with rechargeable lithium ion batteries, which ha...

Using 100-year-old minerals processing methods, chemical engineering students have found a solution to a looming 21st-century problem: how to economically recycle lithium ion batteries. Lei Pan’s team of chemical engineering students had worked long and hard on their research project, and they were happy just to be showing their results at the People, Prosperity and the Planet (P3) competition last April in Washington, DC. What they didn’t expect was to be mobbed by enthusiastic onlookers.56-58F

“We got a lot of ‘oh wow!’ responses, from eight-year-olds wanting to know how it w...

The 3D-printed artificial neural network can be used in medicine, robotics and security. Electrical and computer engineers have created a physical artificial neural network that can analyze large volumes of data and identify objects at the actual speed of light. The device was created using a 3D printer.

Numerous devices in everyday life today use computerized cameras to identify objects – think of automated teller machines that can “read” handwritten dollar amounts when you deposit a check, or internet search engines that can quickly match photos to other similar images in their databases...
