Development of a flexible, wearable and rechargeable battery
Abstract
Lithium battery technology is typically encased in metal or hard plastic packaging which, for some applications, is a drawback especially when the battery is to be carried by humans. The hard packaging and rigid structure can provide a host of ergonomic issues. In order to alleviate these issues we have developed a flexible and rechargeable battery system as part of a new wearable technology.The rechargeable lithium metal battery is based on advanced conductive textiles and electrolytes which allows the device to be flexed as it is charged and discharged. Moreover, using textiles allows battery size and shape to be readily user defined without the need for significant changes to materials processing and assembly. The first large scale prototypes (7 x 15 cm) showed promising performance and cyclability with a capacity of 15 Ah kg-1 and a discharge energy of 40 Wh kg-1 at a rate of C/10. Our current research efforts are focussed on increasing the energy density of the battery system.
