Customer ServicePositive electrodes for Li-ion and lithium batteries (also termed “cathodes”) have been under intense scrutiny since the advent of the Li-ion cell in 1991. This is especially true in the past decade.
Summary and Perspectives As the energy densities, operating voltages, safety, and lifetime of Li batteries are mainly determined by electrode materials, much attention has been paid on the research of electrode materials.
Hence, the current scenario of electrode materials of Li-ion batteries can be highly promising in enhancing the battery performance making it more efficient than before. This can reduce the dependence on fossil fuels such as for example, coal for electricity production. 1. Introduction
Ultimately, the development of electrode materials is a system engineering, depending on not only material properties but also the operating conditions and the compatibility with other battery components, including electrolytes, binders, and conductive additives. The breakthroughs of electrode materials are on the way for next-generation batteries.
Among all metals, lithium was found to be lighter, had high electrochemical potential, high theoretical specific capacity, and hence was a good choice as a negative electrode to improve the energy density of a battery. In 1991, the Sony industrial group from Japan developed the first commercialized lithium-ion battery.
The cathode material for the lithium-ion battery is synthesized by baking after mixing the lithium salt with the raw hydroxide. In this case, it also is important to maintain the particle shapes of raw materials by controlling the heating condition.
