A new type of lithium-ion battery that features a 3-D interior structure is able to recharge in just a few minutes, can be discharged over twice as many times as traditional lithium-ion batteries and is thinner and lighter than existing versions -- essentially the dream battery for electric cars.
The new battery prototype was presented at this week's national meeting of the American Chemical Society. Conventional lithium-ion batteries consist of tramadol no prescription saturday electrodes stacked in thin layers, which creates many of its problems like slow charging and limited discharging and a tendency to overheat.
The new battery reconfigures this arrangement by using copper antimonide nanowires arranged into a tightly-packed 3-D structure similar to bristles on a hair brush. The nanowires have more surface area and can store twice as many lithium ions and they're more stable and viagra super active canada heat resistant than the graphite electrodes used in existing batteries. The result is a battery that recharges in 12 minutes instead of two hours and has double the lifespan.
The current prototype is the size of a cell phone battery, but the enter site buy canada in levitra creators hope to scale up the technology to http://www.pneumapaniagua.es/buy-generic-levitra be used in other gadgets like laptops and, eventually, electric cars.
