Batteries that swap liquid electrolytes for solid materials promise to charge faster, last longer, and (crucially) run cooler. The rise of the lithium-ion battery, which powers everything from the smallest personal electronics to gargantuan energy storage systems, has been nothing short of revolutionary. But as anyone who's boarded a plane in the last decade could tell you, storing and pumping out energy by moving charged lithium ions through a liquid electrolyte soup has its drawbacks, not least that the batteries have a troubling tendency to catch fire. Enter the solid-state battery, which swaps liquid for a solid ceramic or polymer, creating power packs that charge faster, last longer, cram more energy into smaller spaces, and (crucially) run cooler. A new generation of companies aim to bring such batteries to market, and if their bets pan out, the tech could substantially ease the shift away from fossil fuels. Solid-state batteries have been "just a few years away" for more than a decade now.

Apple's largest Pro iPhone gets its biggest battery upgrade yet to make it a true two-day phone with new Siri AI and a variable aperture camera. The iPhone 18 Pro Max is the supersized sibling of the regular 18 Pro and, though it is no longer Apple's most expensive phone thanks to the £2,000 iPhone Duo, it has a similarly large price tag to match costing from £1,299 (€1,599/$1,299/A$2,299). The 18 Pro Max follows the familiar formula of its Pro Max predecessors: take everything that's great about the 18 Pro and supersize the screen and the battery.

From e-bikes to stoves, here's how companies are adding energy storage in surprising ways. If you want to install a big battery in New York City, you have to cut through a notoriously tough tangle of regulations. That's made it difficult to get large energy storage projects on the grid. Faced with those obstacles, some startups are getting creative, finding ways to use relatively small batteries in unexpected places, from induction stovetops to food carts. By deploying these more consumer-focused batteries, the companies are helping people directly, cutting pollution or power bills. And these units, while small on their own, could add up to a lot of capacity.
