Dendrites - the microscopic, pin-like fibers that cause rechargeable batteries to short circuit - create fire hazards and can limit the ability of batteries to power our smart phones and store renewable energy for a rainy day.
Now a new electrolyte for lithium batteries that's described in Nature Communications eliminates dendrites while also enabling batteries to be highly efficient and carry a large amount of electric current. Batteries using other dendrite-limiting solutions haven't been able to maintain both high efficiencies and current densities.
The supermassive black hole is 40 million times as massive as the sun and powers a quasar that existed 700 million years after the Big Bang.
The OnePlus Watch 2 is touted for having incredible battery life for a Wear OS watch, and that saved me when I forgot the charger on a trip.
Vision Pro is here and it’s a surprisingly capable device. Apple has also loaded the headset with a ton of options and features that aren’t obvious at first glance.
