Researchers from institutions in India and South Korea have collaborated to develop a portable supercapacitor that can be charged using light. This advancement shows promise in replacing conventional lithium-ion batteries in portable and wearable devices like smartphones and smartwatches. Supercapacitors have the advantage of quick charge and discharge capabilities, making them ideal for applications requiring short power bursts. The device features a stainless steel electrode with a quartz transparent window to capture visible light, enabling light-induced charging. With the ability to charge devices by simply exposing them to light, this innovation opens up possibilities for long-lasting power in various applications, including electric vehicles and space technologies.
