Silicon “sandwiches” make for lightweight, high-capacity batteries
The pursuit of better batteries means the exploration of alternative materials, and one that scientists see a lot of promise in is silicon. A team at Clemson University has come up with a new design that overcomes some of the problems with incorporating this material into lithium-ion batteries, enabling them to demonstrate a lightweight and multipurpose device that could be used to power satellites and spacesuits.
Scientists have been investigating the potential of silicon in lithium-ion batteries for a long time, and with good reason. Using the material for the anode component instead of the graphite used today could increase the storage capacity of these devices by as much as 10 times, but there are a few kinks to iron out first.

Nano-diamond self-charging batteries could disrupt energy as we know it
California company NDB says its nano-diamond batteries will absolutely upend the energy equation, acting like tiny nuclear generators. They will blow any energy density comparison out of the water, lasting anywhere from a decade to 28,000 years without ever needing a charge. They will offer higher power density than lithium-ion. They will be nigh-on indestructible and totally safe in an electric car crash. And in some applications, like electric cars, they stand to be considerably cheaper than current lithium-ion packs despite their huge advantages.
The heart of each cell is a small piece of recycled nuclear waste. NDB uses graphite nuclear reactor parts that have absorbed radiation from nuclear fuel rods and have themselves become radioactive. Untreated, it’s high-grade nuclear waste: dangerous, difficult and expensive to store, with a very long half-life. READ MORE.
