Lithium-ion batteries have transformed everything from consumer electronics to electric vehicles and energy storage. But to power the next wave of tech — from planes to smartphones — they need to get denser. One option is to replace the graphite anodes within them with silicon ones. Silicon anodes can store 10 times the amount of lithium ions that graphite can and they take up a lot less space
