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.
Developing active materials for the positive electrode is important for enhancing the energy density. Generally, Co-based active materials, including LiCoO 2 and Li (Ni 1–x–y Mn x Co y)O 2, are widely used in positive electrodes. However, recent cost trends of these samples require Co-free materials.
The composition of the alloy was the same as the positive grid produced by gravity casting. The counter electrode, with an approx. five times greater area compared to the working electrode, was made of pure lead (99.98% Pb, Avantor). Preparation of positive electrodes for the capacity test consisted of three main stages.
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).
All-solid-state lithium secondary batteries are attractive owing to their high safety and energy density. Developing active materials for the positive electrode is important for enhancing the energy density. Generally, Co-based active materials, including LiCoO 2 and Li (Ni 1–x–y Mn x Co y)O 2, are widely used in positive electrodes.
Some important design principles for electrode materials are considered to be able to efficiently improve the battery performance. Host chemistry strongly depends on the composition and structure of the electrode materials, thus influencing the corresponding chemical reactions.
