A new battery design from the University of Texas at Austin may help address some issues of current lithium batteries, with the researchers demonstrating a new type of architecture that is entirely free of cobalt.

Scientists from the University of Southern Denmark have created a substance that is able to absorb and store oxygen in such high concentrations that just one bucketful is enough to remove all of the oxygen in a room. The stored oxygen is able to be released in a controlled manner when it is needed.
