Lithium Ion Batteries Based On Nanoporous Silicon

技术优势: Low cost and simple fabricationCompatible with standard lithography techniquesHigh power capacity and extended cycling life

技术应用: Portable electronicsMEMS, mobile phones, music players, notebooks, sensors

详细技术说明: Researchers at UCLA have formed novel Li+ secondary battery electrodes that demonstrate high power capacity and retention of structure through many charge/discharge cycles. The conventional graphite electrode is replaced with a porous film of silicon nanowires, with a structure that is controllable during the alloying/dealloying process eliminating its associated volume changes. Furthermore, because the porous nanowires are made by etching of Si wafers, this technology also has the potential to be integrated with other lithographically produced devices.
