Nano-diamond self-charging batteries could disrupt energy as we know it

 Via NewAtlas: Here shown as a small, circuit board mounted design, the nano diamond battery has the potential to totally upend the energy equation since it never needs charging and lasts many, many years - NDB
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.
This graphite is rich in the carbon-14 radioisotope, which undergoes beta decay into nitrogen, releasing an anti-neutrino and a beta decay electron in the process. NDB takes this graphite, purifies it and uses it to create tiny carbon-14 diamonds. The diamond structure acts as a semiconductor and heat sink, collecting the charge and transporting it out. Completely encasing the radioactive carbon-14 diamond is a layer of cheap, non-radioactive, lab-created carbon-12 diamond, which contains the energetic particles, prevents radiation leaks and acts as a super-hard protective and tamper-proof layer...

Silicon "sandwiches" make for lightweight, high-capacity batteries (Score: 1)

(User Info | Send a Message) http://www.zpenergy.com | | Silicon "sandwiches" make for lightweight, high-capacity batteries
Lithium-ion batteries could one day be a whole lot lighter, and carry a whole lot more charge, thanks to a new sandwich-like design of the anode component
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...

High-density hybrid powercapacitors: A new frontier in the energy race (Score: 1)

(User Info | Send a Message) | Via NewAtlas.com: High-density hybrid powercapacitors: A new frontier in the energy race
Hybrid "power capacitors" that can store as much energy as lithium batteries, but with much higher charge/discharge rates, a huge range of safe operating temperatures, super-long lifespans and no risk of explosion are already in production, says a small Belgian company that's been testing them and selling them for some time.
Chinese family-owned company Shenzhen Toomen New Energy is tough to find, at least on the English-language internet, but Belgian electronic engineer Eric Verhulst bumped into Toomen representatives on a tiny stand at the Hannover Messe expo in Germany back in 2018, while looking for next-gen battery solutions for an electric mobility startup he was running.
The Toomen team made a hell of a claim, saying they'd managed to manufacture powerful supercapacitors with the energy density of lithium batteries. "Of course, that's an unbelievable claim," Verhulst told us. "It's a factor of 20 better than what, for example, Maxwell had at the time. So I took my time, went over there, looked at their tests, did some tests myself, and I got convinced this is real. So at the end of 2018, we made an agreement to become their exclusive partner."...

Arkenlight "surprised" by NDB's grand nuclear diamond battery claims (Score: 1)
by vlad on Thursday, October 01, 2020 @ 22:24:56 UTC
(User Info | Send a Message) http://www.zpenergy.com | | Via NewAtlas: ...The claims that caused the uproar were around the technology's utility in consumer devices. NDB representatives told us in an interview that if the company made one of these cells the same size as an iPhone battery, "it would charge your battery from zero to full, five times an hour", for decades. They said they could replace the battery in a Tesla
electric car with something slightly more powerful that'd last some 90
years without ever needing a charge, and would come in cheaper than a
standard Tesla battery. Commenters – and indeed YouTube debunkers
– called us out for publishing these claims, saying that carbon-14
simply can't produce energy fast enough to be useful in a device that
requires sustained high power draws. The diamond part of the battery
would charge up the supercapacitor so slowly, they pointed out, that
either you'd need a much, much larger quantity of it, or you'd need to
find applications that give the supercapacitor a long time to charge
itself up between high-power discharges. The idea of using one in a
phone or a car, they said, was laughable. We're in the process of
arranging a follow-up interview with the NDB team to clarify exactly
what their energy production claims are, but in the meantime we decided
to reach out to Professor Tom Scott, ... Full article: https://newatlas.com/energy/arkenlight-nuclear-diamond-batteries/

"World's fastest electrodes" triple the density of lithium batteries (Score: 1)

(User Info | Send a Message) http://www.zpenergy.com | | "World's fastest electrodes" triple the density of lithium batteries Via NewAtlas.com: Nawa Technologies says that moving electrodes to a rigidly structured vertical array of carbon nanotubes, coated with an active material like lithium-ion, can radically boost power density, energy density, charging speed and battery lifespan with no cost penalty.
French company Nawa technologies says it's already in production on a new electrode design that can radically boost the performance of existing and future battery chemistries, delivering up to 3x the energy density, 10x the power, vastly faster charging and battery lifespans up to five times as long.
Nawa is already known for its work in the ultracapacitor market, and the company has announced that the same high-tech electrodes it uses on those ultracapacitors can be adapted for current-gen lithium-ion batteries, among others, to realize some tremendous, game-changing benefits...

From the National Accelerator Laboratory: Adding polymers and fireproofing to a battery’s current collectors makes it lighter, safer and about 20% more efficient.
Menlo Park, Calif. — In an entirely new approach to making lithium-ion batteries lighter, safer and more efficient, scientists at Stanford University and the Department of Energy’s SLAC National Accelerator Laboratory have reengineered one of the heaviest battery components – sheets of copper or aluminum foil known as current collectors – so they weigh 80% less and immediately quench any fires that flare up...

(User Info | Send a Message) http://www.zpenergy.com | Skeleton Technologies - powering energy savings with ultracapacitors
What are ultracapacitors?
Ultracapacitors, or supercapacitors as they are also known, are an energy storage technology that offers high power density, almost instant charging and discharging, high reliability, and very long lifetimes.
Ultracapacitors have been in development for decades but the technology has developed rapidly in the recent years. This development has been driven by advances in nanomaterials - Skeleton Technologies' Curved Graphene is a prime example - the electrification of infrastructure and industry, and increased concerns around fuel efficiency and emissions in the automotive and transportation segments.
Ultracapacitors are now delivering significant economic benefits across a wide range of markets including automotive, grid & renewables, transportation and industrial applications.
