Boeing is frantically trying to save face in the wake of several electrical failures and at least one fire on several of its its much ballyhooed 787 Dreamliner airliners. Authorities in the U.S. and Japan are currently investigating the fires, and now one of the world’s best known inventors has chimed in by criticizing the battery technology onboard the planes.
In the quest for better energy storage, researchers have investigated all manner of thin, flexible battery technology, power sources based on kinetic energy, and even batteries integrated into clothing. How about batteries you can paint onto any surface? According to research published in the June 28 issue of Scientific Reports, new “spray-on” battery technology could potentially turn any surface into an energy storage device. Continue reading
We’re always happy to hear about any advancements that can improve the performance of rechargeable batteries — particularly if those advancements could make lithium ion batteries robust enough for transportation and renewable energy storage applications.
A group of researchers at Stanford published a paper in March in the journal Nature Nanotechnology describing their work using silicon, as opposed to graphene, as an anode material in lithium ion batteries. While silicon has a larger charge storage capacity, it has inherent properties that make it less stable than graphene, which limits the lifecycle of silicon anodes to hundreds of cycles.
