Apple is famous for making nice looking products that are practically sealed for life even though many of us consider the internal battery a serviceable part. Having to access batteries for occasional replacement might be a thing of the past. Also planning to charge items is currently something that revolves around many things, you probably plan to charge your phone while you sleep, your electric car gets topped up when you are at work, you have a few sets of batteries for your cordless power tools. Wouldn’t it be nice it charging took a few minutes instead of many hours? How about a battery that lasts 20 years, which is typically more than the entire usable life of the device? This might not be science fiction for much longer. Scientists at Nanyang Technology University have developed fast charging batteries that can be recharged up to 70 per cent in only two minutes!
Thanks for the tip John.
“In the new NTU-developed battery, the traditional graphite used for the anode (negative pole) in lithium-ion batteries is replaced with a new gel material made from titanium dioxide.
Titanium dioxide is an abundant, cheap and safe material found in soil. It is commonly used as a food additive or in sunscreen lotions to absorb harmful ultraviolet rays.
Naturally found in spherical shape, the NTU team has found a way to transform the titanium dioxide into tiny nanotubes, which is a thousand times thinner than the diameter of a human hair. This speeds up the chemical reactions taking place in the new battery, allowing for superfast charging.”
