Positive 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.
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. The objective of this review is to provide a simple yet comprehensive understanding of LiBs and their electrodes.
In commercialized LIBs, Li insertion materials that can reversibly insert and extract Li-ions coupled with electron exchange while maintaining the framework structure of the materials are used as both positive and negative electrodes.
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.
Several new electrode materials have been invented over the past 20 years, but there is, as yet, no ideal system that allows battery manufacturers to achieve all of the requirements for vehicular applications.
IL was selected as an effective additive for capacity tests of the positive electrode. Decrease of corrosion rate of the positive electrode in the modified system was observed. The decrease in the value of corrosion current, a shift in the corrosion potential by more than 200 mV was also observed.
