There is a rapid rise of IoT electronic portable devices in recent years, including wearables (from go-pros and smart watches to the burgeoning field of Augmented Reality (AR) eyewear) and portable, micro size medical devices (i.e. hearing aid or heart pacemaker). These emerging industries require novel, high capacity, long life time, rechargeable batteries that are increasingly small, lightweight to fit existing and future smart electronics –e.g. fitting within the wrist band of a smartwatch, or within the rims of smart glasses. Following the outcome of 3 years of development research and extensive testing, 3DB present a novel generation of button rechargeable Li-ion battery for high power high energy applications of significantly improved performance and costs points versus the current state of the art technologies/products. The proposed project targets an up-scale process and the development of production facilities to validate their novel production methods. The advancements over the project include a cost-effective production process, stable production to support marketing and certify process, and demonstrating enhancement of the specific energy density by a factor of at least 3 times (in comparison to the commercial button battery) while maintaining the high cycling stability, dimensions, and cost.
