Nickel-based batteries: materials and chemistry

This chapter provides a comprehensive review on Nickel-based batteries, where nickel hydroxide electrodes are utilised as positive plates in these batteries. An example is the popular nickel/metal hydride batteries, which are one of the most important power sources for a wide range of electronic devices. The chapter first gives a brief history of these batteries, the fundamental electrochemistry behind this system. It will detail the construction of the batteries, including the active materials and electrolyte. The chapter will compare the performances, the advantages and limitations of different types of battery in this system. New materials to be applied in this system, the current development and the future trend of these Ni-based batteries will be discussed.
