Biodegradable electronics represent an emerging class of technology with potential to provide advanced semiconductor functionality in temporary biomedical implants. This work reported a biodegradable primary battery as a potential power source for these systems, which uses biodegradable metal foils and polyanhydride packages. Monolithically integrating cells yields battery packs with sufficient power to operate conventional light emitting diodes and radio transmitters.

This chapter is a general introduction to the more common types of metal-air batteries, with emphasis on using the magnesium-air technology as an example in understanding the various components that make up a metal-air battery, and some of the limitations, challenges, manufacturing, and further research. Much of what has been learned can be applied to the other aqueous metal-air technologies. Products that utilize metal-air technology as their power source are or have been developed. Various theoretical calculations of the metal-air types have been compared in many published articles, but they do not reflect the actual operating conditions for commercial products. Similar to any commercial product, first to market is a test of consumer acceptance indicating product and financial returns to the manufacturer. The consumer has accepted battery types such as lead-acid, and zinc alkaline batteries for years and is only being introduced to the concept of metal-air batteries, though the zinc-air button cell for hearing aids has been around for years. Metal-air battery types may have certain niche commercial products, and no one metal-air type reigns supreme.Metal-air batteries [1-4] are one of the more promising, but less well known, alternatives to conventional and future power sources as primary cells. Metal-air systems are typically very high in energy density but low in power, have an open cell structure, and use oxygen from the air. Great strides have been made and are continuing to be made in the metal-air technology. They have the potential to replace conventional batteries (e.g., zinc alkaline) and high cost hydrogen-based fuel cells because of their high energy density, relatively flat discharge voltage potential, long shelf life, and relatively low manufacturing cost.Metal-air batteries are an attractive power source for stand-alone power supplies (e.g., for stand-by or emergency power and portable power). They feature the electrochemical coupling of a metal anode to an air-diffusion cathode through a suitable electrolyte. This combination produces a cell with an inexhaustible cathode reactant from the oxygen in atmosphere air. Metal-air batteries also have the versatility of an aqueous or nonaqueous electrolyte.

“…With the increasing presence of MEMS devices in a wide range of technologies, there is a growing need to develop high-performance electrical energy storage technologies with high power density and ease of fabrication [2]. The two major power sources for portable devices are batteries and capacitors, which have historically lagged behind the development of micro-electronic circuits, in areas such as system integration density [3].…”
