Hold onto your phones📱—Chinese scientists just cracked the code for a *water-based battery* that packs way more power and doesn’t burst into flames! 🔥 Researchers from the Chinese Academy of Sciences (CAS) unveiled a new aqueous battery using halogen tech, which could revolutionize everything from EVs to your gadgets.
Traditional lithium-ion batteries? They’re energy-dense but risky (remember exploding phones?). Aqueous batteries use water-based electrolytes, making them safer, but they’ve always lagged in energy storage. Until now🌊.
By mixing bromide and iodide ions, the team created a multielectron transfer reaction, boosting the battery’s capacity to *840 Ah/L*—way beyond current standards. Paired with a cadmium anode, they hit an energy density of 1,200 Wh/L—like swapping a scooter battery for a sports car engine🚗⚡.
Lead researcher Li Xianfeng says this breakthrough could push aqueous batteries into the big leagues for power storage, offering safer, greener alternatives. Imagine renewable energy grids or EVs that charge faster and won’t overheat! 🌱🔋
Science geeks, this is huge. The study, published in Nature Energy, solves the sluggish reaction issues in water-based batteries, making them both efficient and scalable. Future tech just got a major upgrade✨.
