One of the main obstacles to effective renewable energy storage and large carbon emission reductions is battery capacity. In a lithium-ion battery (LIB), Tin (Sn) and Sn-mixture alloys could be used as a battery anode that releases electrons, potentially storing more energy at a higher density than more typical carbon-based anodes.
Whether it is Alexa listening to our every move, home CCTV cameras watching over our homes, or our phones detecting every step we take, we’re used to our gadgets monitoring our lives. And now one highly experimental piece of technology looks set to take it even further – and could even become capable of watching us through walls.
