A group of scientists from Singapore's Nanyang University announced the discovery of which significantly improve lithium-ion batteries. The latter is widely used in mobile electronics, charging long runs down quickly and also quickly lose their ability to maintain capacity.
The best modern lithium-ion batteries can withstand about 500 charge / discharge cycles without significant degradation of capacity, while the mass of batteries - about 200-250. Scientists in Singapore claim that their invention will make lithium-ion batteries to withstand up to 10 thousand. cycles - about 20 times more than usual.
Another important innovation is the ability to charge to 70% capacity in just a few minutes. One can only imagine the speed - enough for full charging time, during which you can not properly take a cup of coffee or tea.
The new characteristics of lithium-ion batteries to provide the anode, made of titanium dioxide nanotubes. The traditional graphite anode has a limited area of contact with the reagent. The nanotubes in this case, just a huge contact area, which allows the battery to charge fast and strong to withstand huge in a very short period of time.
When will it appear in a serial product? According to the researchers, two, three or more years, when testing high-capacity batteries will be successful. Researchers hope that massive stimulus is the car manufacturers are offering more and more electric.
