Wearable Lithium-Ion Batteries Using Textile-Graphene Composite Electrodes

Wearable electronic technology will be the next big market opportunities after smartphones. Its market revenue is ~US$ 2 billion now, and is expected to reach US$ 30~50 billion by 2018. One bottleneck challenge of wearable electronic devices is that the energy supply module should meet not only the power needs of these devices, but also wearable specifications (e.g., lightweight, flexible, foldable, safe). Unforturnately, current lithium-ion (Li-ion) batteries, the main choice of portable power source, are rigid, bulky, heavy, and use leakage-possible liquid electrolyte. To address those challenges, this project aims for developing a wearable type of Li-ion batteries using textile/graphene electrodes and solid electrolytes. Metallic textile/graphene composite electrodes will be used as lightweight, flexible, foldable, highly conductive, and high capacitance electrodes. Polyelectrolyte gels will be used as solid separator and electrolytes to provide good flexibility and leakage-free property. The device performance will be optimized to achieve good level of energy desity but much better wearing properties, when compared with rigid type Li-ion batteries. The success of this project shall deliver a novel and versatile textile-based wearable battery technolgy, which will make a significant impact in a wide range of wearable electronic applications including display, energy harvesting, biomedical devices, GPS and fashion.
