Today

Most of today's exotic rechargeable battery systems--nickel-cadmium, nickel-metal hydride, and the variety of lithium-based cells--are 20th Century developments, products of research labs at major corporations and universities. New chemistries are no longer discovered through experimentation because the principles of battery design and operation are now well known. Today new efforts in battery design focus on making the optimal chemistries work in practical cells.
