Monash University Associate Professor Matthew Hill, Dr. Mahdokht Shaibani, and Professor Mainak Majumder with the lithium-sulphur battery design.Monash University The name "lithium-ion battery" seems to imply that lithium is the essential ingredient that dictates the battery's performance characteristics. But that's less true than it appears. The electrodes that the lithium shuttles between are critical for…

Enlarge / Challenges scale considerably when the battery pack weighs 300kg. Lithium batteries have become incredibly popular for electronic devices, and the emphasis on weight and size for those batteries means that the amount of raw materials tied up in them isn't too large. But that's absolutely not the case for the other growing use…

James Pikul Lots of experimental robots involve a little bit of cheating. Rather than containing all the necessary electronics and energy sources, they have tethers and wires that provide power and control without weighing the robot down or taking up too much internal space. This is especially true for soft-bodied robots, which typically pump air…

Currently, the world is struggling to keep its carbon emissions from rising. But to reach the longer-term goals we have for stabilizing the climate, we're going to have to do far more than roll out some renewable energy. Keeping the earth from warming by 2°C above preindustrial temperatures means a deep decarbonization of our energy…
