Source: Phys.org news January 8, 2018, Zhejiang University. Aluminum-ion batteries (AIB) have significant merits of low cost, non-flammability, and high-capacity metallic aluminum anodes based on three-electron redox properties. However, due to its inadequate cathodic performance, especially in terms of capacity, high-rate capability, and cycle life, AIB still cannot compete with Li-ion batteries and supercapacitors.

Batteries simply aren’t powerful enough to enable the design of a svelte Apple Watch that can run for more than a day between charges. That might be fine for a single prized object on your wrist, but it can’t possibly […]
