Requirements of next-generation batteries will focus on low cost, light weight, compact packaging, portability, and longevity exceeding 15 years. Rechargeable batteries will be found most suitable for battlefield weapons, communication satellites, space reconnaissance and surveillance systems, underwater tracking sensors, and a host of several applications. Note that high-capacity batteries are best suited for commercial and military aircraft, helicopters, drones, hybrid vehicles, space sensors, and battlefield weapons, whereas low-power rechargeable batteries are widely deployed by the cell phones, laptops, medical devices, computers, and host of other electronic and digital devices. e integration of microminiaturization technology [1] involving the microelectrical mechanical system (MEMS) and nanotechnology techniques will be given serious consideration in the design and development of next-generation rechargeable batteries to meet the stringent performance specifications, including reliability, portability, longevity, and compact packaging.
