From faster charging to longer range: 3 types of silicon tech that’ll revolutionize EV batteries


As car manufacturers and battery cell makers race to develop more efficient and faster-charging EV batteries, there’s one material that’s been gaining significant traction in replacing mainstream graphite in the battery’s anode: silicon. That’s because silicon has a theoretical energy capacity 10 times higher than that of graphite, meaning it can significantly increase an EV’s range. It can also absorb lithium-ions much quicker during charging — speeding up the process. But adding silicon to the anode comes with certain challenges. The material’s tendency to expand approximately 400% of its original size during the charging cycle can cause the silicon particles…

Swiss startup believes this forgotten element is the key to safe nuclear energy

Nuclear energy is undergoing a renaissance. Across Europe, governments are pouring huge amounts of money into new power plants while startups are busily working on smaller, modular alternatives.  Most of these plants rely on uranium, the radioactive metal that fuelled the atomic age (and contributed to a couple of catastrophic meltdowns). However, Swiss startup Transmutex wants to reinvent nuclear energy using a lesser-known element called thorium.  Uranium’s forgotten cousin Thorium is a lead-like metal that is mildly reactive, but four times more abundant than uranium and a lot safer to handle. However, thorium is a fissionable material but not a… This story continues at The Next Web from The Next Web https://ift.tt/ideQqVM

Insta mules and crypto mixers: How tech is transforming money laundering

On the shallow surface of Instagram, Ramon “Hushpuppi” Abbas was a quintessential influencer. The flamboyant Nigerian portrayed a lavish lifestyle of private jets, luxury cars, and designer clothes. His glamorous adventures had earned him over 2 million followers and millions of dollars. But his posts concealed a darker reality. The 41-year-old was “one of the most prolific money launderers in the world,” according to the FBI. By his own admission, Hushpuppi conspired to launder over $300mn in just 18 months. One of his alleged clients was a certain Kim Jong Un — the supreme leader of North Korea. With his… This story continues at The Next Web from The Next Web https://ift.tt/rd549ui
