Researchers in India have invented a storage device using green tea extract. The device is flexible, compact and rechargeable and can be inserted in wearable electronics including watches and sports bands. Polyphenols, which is an element from green tea, can be charged rapidly and discharged repeatedly - ideal for an energy storage device. Most batteries are made from durable, hard and rigid materials, so this breakthrough could be the start of more flexible energy devices. The team from India's Council of Scientific & Industrial Research (CSIR) took an interesting approach. The researchers prepared polymer gels in green tea extract, which infuses the…
