10 minutes patience……:)
Researchers have developed a new lithium-ion battery that can recharge within 10 minutes and hold thrice as much energy as its existing counterparts. The new batteries could be used in anything from cell phones to hybrid cars. The design, currently under a provisional patent, could become commercially available within two to three years.
Researchers have long attempted to use silicon, which is cheap and has a high potential capacity, in battery anodes. (Anodes are where current flows into a battery, while cathodes are where current flows out). The problem has been that previous silicon anode designs, which were basically tiny plates of the material, broke down from repeated swelling and shrinking during charging/discharging cycles and quickly became useless.
The tiny pores on the nano-wires allowed the silicon to expand and contract without breaking while simultaneously increasing the surface area – which in turn allows lithium-ions to diffuse in and…
