While our electronic gadgets are evolving by the day, a common bottleneck faced is the outdated battery technology. Luckily, quite a few technological researches looks promising for the future battery technology - be it the COTA Wireless charging, the superfast NanoDot Smartphone Charger (Recharges in 30 seconds) or the all new ultra-fast charging batteries that last 20 years from Scientists at Nanyang Technology University (NTU).
The new lithium ion batteries can reach a 70% charge in two minutes and last for over 20 years. The change that did the trick was using titanium dioxide nanotubes for the anode (the negative pole) instead of conventional graphite which speeds up the battery's chemical reactions while offering 10,000 charging cycles instead of the usual 500. Since the mini titanium tubes are both easy to make and relatively inexpensive, the technology should not be far away from consumer usage.
