Scientists can now see the exact moment lithium-ion batteries start to fail, paving the way for charging technology that could make your phone battery last years longer. The breakthrough could transform how we charge everything from smartphones to electric vehicles.
Scientists in Hong Kong created a water-based battery using the same brine that makes tofu, and it can withstand 120,000 charge cycles. Unlike lithium-ion batteries that can explode and create toxic waste, this design is safe enough to dispose of anywhere.
Scientists are solving the biggest hurdles holding back a safer, longer-lasting alternative to lithium-ion batteries for powering entire cities. Their breakthrough could make renewable energy more reliable for millions.
A new free program in North Queensland is making it easy to safely dispose of lithium-ion batteries after fire incidents more than doubled since 2022. The initiative covers everything from electric toothbrushes to e-scooters, protecting communities and waste workers from dangerous fires.
Australian researchers developed a green method to extract valuable minerals from old lithium-ion batteries with a 95% recovery rate. The breakthrough could turn millions of tonnes of battery waste into treasure while keeping toxins out of landfills.
Japanese researchers built a handheld reactor that generates electricity from hydrogen fuel, offering four times the energy density of lithium-ion batteries. The device heats to 600°C in five minutes but stays cool to touch, solving a major barrier to portable power.
Google is building massive CO2 batteries that can store clean energy three times longer than lithium-ion batteries at 30% lower cost. The inflatable dome technology could finally solve the challenge of keeping data centers powered around the clock with renewable energy.
