Chinese Advanced and Cheap Rechargeable Battery

Abstract

With the development of Chinese industrial technique, electronic products tend to be small sized and portable. So it required batteries to be miniature, light weight, with high energy capacity and long service life. China had achieved great progress in electrochemical power sources industry in the last ten years. Especially, there is an ceaseless developing trend in the rechargeable battery field. Chinese chemical power source investigators had done a great deal of work on lead-acid, nickel-iron, nickel-cadmium (Ni-Cd), nickel-metal hydride (Ni-MH) and lithium ion batteries, among which, lead-acid, nickel-iron, nickel-cadmium and nickel-metal hydride batteries are produced in commercial scale. And some hopeful results were also achieved on rechargeable lithium batteries and lithium ion batteries. In this article we concentrate on the introduction of the research, development and manufacture status of nickel-cadmium and nickel-metal hydride batteries, hoping that this paper will give a deeper understanding in the field of Chinese rechargeable batteries.
