If there's one major issue plaguing smartphones, smartwatches and other gadgets we use every day, it's battery life. Now, a team of researchers at Stanford University has built an aluminum-ion battery prototype which offers several improvements over today's ubiquitous lithium-ion batteries, including super-fast charging times.
