Pseudocapacitive Materials for Metal-Air Batteries

Clean energy storage is a problem faced by many nations around the world. These issues range from storing fluctuating energy from green energy storage to improving the battery life of smart devices. Additionally, the need for flexible electronics is rapidly rising in the medical and private fields of use. All these devices require storage sources with high energy density, long life, and reusability. Metal air batteries (MABs) exist as an up-and-coming device that can fit each of these needs handily. MABs boast an incredibly high potential energy density, environmental compatibility, and potential for reuse or recharge. Additionally, specific engineering methods allow for these devices to be engineered for high flexibility. To further improve the efficacy of these devices, pseudocapacitive integration has been explored. By imbuing a redox nature further energy storage is possible. Given these facts, the functionality of MABs is explored in brief, alongside the integration of different materials to improve their performance and flexibility.
