  • Supercapacitor electrode promises faster battery charging (11/03/15)
    Researchers have developed a novel electrode to make low-cost, lightweight supercapacitors with superior performance, a development that could mean faster charging time and longer battery life.

  • Protective film extends life of Li-ion batteries (11/03/15)
    Arizona researchers developed a protective film that prolongs the life of lithium-ion batteries. The solution containing silicon electrode and an ionic liquid electrolyte maintains 75 per cent battery capacity.

  • Glass coating lifts lithium-sulfur battery performance (04/03/15)
    UC, Riverside researchers found a way to prevent "polysulfide shuttling" phenomenon in lithium-sulfur batteries by creating nano-sized sulfur particles, and coating them in silica, otherwise known as glass.

  • Novel flow battery packs more power to support large cities (03/03/15)
    The PNNL zinc-polyiodide flow battery from Pacific Northwest National Laboratory promises to minimise the battery's size and cost and makes it ideal to store energy in densely populated cities.

  • Wearable device 'alarms' upon fever onset (02/03/15)
    The fever alarm armband combines a flexible amorphous silicon solar panel, piezoelectric speaker, temperature sensor and power supply created with organic components in a flexible, wearable package.

  • CMOS-based transceivers target mm-wave radar (27/02/15)
    imec and Panasonic revealed a transceiver chip for phase-modulated continuous-wave radar at 79GHz, which can be used in accurate presence and motion detection.

  • Creating low-cost solar cells using shrimp shells (23/02/15)
    QMUL researchers used chitin and chitosan found in crustaceans to develop electricity-generating solar-cells, which has potential to be used in devices such as tablets, phones and smartwatches.

  • Extending EV battery performance using Si nanofibres (23/02/15)
    University of California, Riverside's Bourns College of Engineering researchers developed a paper-like material for Li-ion batteries that can boost by several times the specific energy of the battery.

  • Doping germanium quantum dots to yield solar cells (19/02/15)
    Scientists working with Natcore Technology developed a tandem solar cell that promises to deliver ultra-high-efficiency, multi-junction capabilities aimed at space applications.

  • Nature mimicry paves way for better Li-ion battery (18/02/15)
    By helping to maintain a highly organised architecture at the nanoscale, the researchers expect that their peptides will improve the power and cycling stability of future Li-ion batteries.
