Smaller, cheaper, safer: The next generation of nuclear power, explained
Lithium batteries started an avalanche of innovation when they became widely available, largely because they could hold significantly more energy by weight than other contemporary chemistries. Touchscreen smartphones, drones, all-day laptops, long-range electric cars and the first generation of battery-powered aircraft were some of the results.
But more energy storage is always better – you can either make things last longer, or weigh less – and manufacturers have been racing to raise the bar with next-gen battery technologies. One key metric in the aviation world is specific energy – the amount of energy stored per kilogram of battery, and CATL says it's ready to set a new benchmark.
