The invention is a method for increasing the airflow to a zinc-air battery such that the energy density is 500 mwh / cc to 1000 mwh / cc. This allows 8 to 16 hours use as a primary (throw-away) battery, with, for example, high-duty cycle, high-drain cochlear implants, and neuromuscular stimulators for nerves, muscles, and both nerves and muscles together. The systems incorporating the high energy density source are also part of the invention, as well as the resulting apparatus of the method. The uses of this inexpensive, i.e., a $1.00 per day, throw-away primary battery are new uses of the modified zinc-air battery and are directed toward helping people hear again, walk again, and regain body functionality which they have otherwise lost permanently.
