A team of scientists from Singapore's Nanyang Technological University announces the development of improved lithium-ion batteries. Batteries - a sore spot in today's mobile electronics. Charged for a long time, are discharged quickly and more quickly lose the ability to accumulate a charge - reloading. The best examples of modern lithium-ion batteries can withstand up to 500 discharge cycles without significant capacity degradation , and mass - 200-250 cycles. Scientists from Singapore's claim that their development can withstand up to 10 thousand discharge cycles, which is 20 times more.
Another important feature of the design is the ability to get up to 70% capacity in just two minutes. Imagine, instead of waiting hours near an outlet device is ready for full operation of the batteries almost immediately.
New properties of the batteries gave anode of titanium dioxide nanotubes. Traditional graphite anode has a limited area for contact with the reactants. Nanotubes with their hollow structure in this plan are just a huge area for the contact, which causes a high rate of charge and the ability to withstand the stunning currents for a short period of time.
