The conventional way of making lithium-ion battery (LIB) electrodes relies on the slurry-based manufacturing process, for which the binder is dissolved in a solvent and mixed with the conductive agent and active material particles to form the final slurry composition.
This review critically discusses various aspects of commercial electrode materials in Li-ion batteries. The modern day commercial Li-ion battery was first envisioned by Prof. Goodenough in the form of the LCO chemistry. The LiB was first commercialized by Sony in 1991. It had a LCO cathode and a soft carbon anode.
Graphite and its derivatives are currently the predominant materials for the anode. The chemical compositions of these batteries rely heavily on key minerals such as lithium, cobalt, manganese, nickel, and aluminium for the positive electrode, and materials like carbon and silicon for the anode (Goldman et al., 2019, Zhang and Azimi, 2022).
Lithium-ion secondary battery is produced through the following key manufacturing process. Yokogawa provides the equipments and solutions that support various battery manufacturing processes. At the positive electrode, active material, conductive auxiliary agent, binder, and organic solvent are mixed to make a slurry for the positive electrode.
Electrode final properties depend on processing steps including mixing, casting, spreading, and solvent evaporation conditions. The effect of these steps on the final properties of battery electrodes are presented. Recent developments in electrode preparation are summarized.
Li-ion battery research has significantly focused on the development of high-performance electrode materials. Electrodes that have characteristics such as high charge capacity, high rate capability, and high voltage (considered for cathodes) can potentially improve the power and energy densities of Li-ion batteries.
