LiCoO 2 (LCO), because of its easy synthesis and high theoretical specific capacity, has been widely applied as the cathode materials in lithium-ion batteries (LIBs). However, the charging voltage for LCO is often limited under 4.2 V to ensure high reversibility, thus delivering only 50% of its total capacity.

With the growing demand for portable electronic devices, electric vehicles (EVs), and renewable energy storage systems, the development of lithium-ion batteries has received unprecedented attention [1], [2]. The positive electrode material is crucial to the performance of LIBs.
The development of Li ion devices began with work on lithium metal batteries and the discovery of intercalation positive electrodes such as TiS 2 (Product No. 333492) in the 1970s. 2,3 This was followed soon after by Goodenough''s

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. Early on, carbonaceous materials dominated the negative electrode and hence most of the possible improvements in the cell were anticipated at the positive terminal; on the
