Consumers may not always understand the trade-off between battery life and slimmer products. So, while they would want extra juice in their devices so that they run all day, they would be tempted by sleeker-looking products. Trying to marry battery life with a slimmer design is what leads to overheating, as companies try to cram more into a single device. Consider this—while in the early 2000s, a phone would have just a chip with limited storage, battery, receiver, speaker and an antenna, these days, it would come equipped with a GPS chip, more battery capacity, an iris-scanner, two cameras, a fingerprint reader and much more. Thanks to the overheating, explosions shook the brand value of top-billed makers the last couple of years. But now a team of scientists have discovered a new way to deliver buffed-out hardware and longer battery life while also ensuring there is no overheating. According to a study published in Science, scientists at the Berkeley Lab have been able to syntehsise a form of vanadium, a good conductor of electricity, but poor conductor of heat.

While vanadium is not new to the game—Nasa has been using this in its products—the vanadium oxide nanobeams developed at the Berkeley Lab are certainly a disruptive entrant. While it can be used for home-based equipment, it can transform the way we look at computing and ultra-portable devices.
