Comments Off on Canadian chemists use vitamins in new sustainable lithium battery

Chemists at the University of Toronto have developed a new battery that stores energy in a cathode derived from vitamins . The breakthrough could eventually lead to batteries that are much cheaper and more environmentally friendly than regular lithium-based batteries, but with similar performance. This development marks the first time a bio-derived polymer has been successfully applied to battery technology, an accomplishment that could unlock a new path for the future of energy storage . Flavin derived from vitamin B2 operates as the cathode in the new battery , which is the part where energy is stored when the battery is connected to an electronic device. Looking to nature for solutions, a design approach called biomimicry made a lot of sense to the research team as they sought to build a better battery. “We’ve been looking to nature for a while to find complex molecules for use in a number of consumer electronics applications,” said Dwight Seferos, an associate professor in the university’s Department of Chemistry and Canada Research Chair in Polymer Nanotechnology.

After much trial and error, and many failures, the team of chemists successfully created a new material from vitamin B2 that begins with genetically-modified fungi and, through a semi-synthetic process, links two flavin units to create a long-chain molecule (in other words, a polymer). The bio-derived polymer makes it possible to create a truly green battery that has both high capacity and high voltage, which are both key elements to running all the portable electronic devices that modern life has come to rely upon. The research was published in this month’s edition of the journal Advanced Functional Materials. Via Phys.org Images via Diana Tyszko/University of Toronto and Shutterstock

Lithium battery technology breakthrough could totally change solar power

Comments Off on Lithium battery technology breakthrough could totally change solar power

Though the obstacles to a clean energy economy are largely political , one particular technological challenge to this goal is the expense and capacity of storage batteries. The sun may shine strongly on a home rooftop, but if there is nowhere to store this energy until peak-demand in the evening, the system is not effective. However, technology may be catching up to demand. While the Tesla Powerwall hopes to be part of the solution, a new method of manufacturing lithium batteries, pioneered by MIT researchers and Cambridge-based company 24M , may cut production costs in half and open up enormous opportunities for renewable energy.   Read the rest of Lithium battery technology breakthrough could totally change solar power Permalink | Add to del.icio.us | digg Post tags: “clean energy” , “wind power” , 24M , battery , battery storage , battery technology , lithium batteries , lithium battery , MIT , renewable energy , renewable energy technology , Solar Power

Comments Off on Ohio Scientists Invent World’s First Rechargeable Solar Battery

A team of Ohio State University scientists have invented what they claim is the world’s first rechargeable solar battery. The team observed the issues in current methods for collecting and storing solar energy – particularly energy loss, which can run at around 20 percent during the process of transferring collected energy to a battery. They then developed a design that integrates a solar panel and battery components into one efficient and cost-effective device.

GE’s Dual-Battery Hybrid Electric Bus Maximizes Storage and Power

Comments Off on GE’s Dual-Battery Hybrid Electric Bus Maximizes Storage and Power

GE’s new hybrid electric bus tosses out the traditional idea of one large battery and replaces it with two different types of batteries working in tandem to maximize both energy storage and energy delivery. The bus was built by the Federal Transit Authority Hybrid Transit Bus team, which includes GE scientists, and features one lithium battery and one sodium battery.  The lithium battery can provide bursts of power for propelling the bus, but can’t store as much energy, while the sodium battery has a larger energy storage capacity, but isn’t able to provide those bursts of power.  Each have their strengths that, coupled together, make up for their shortcomings, resulting in a hybrid system that doesn’t have to compromise on power or range.
