Can lithium cobalt oxide cathodes increase the energy density of lithium-ion batteries?

Extending the charging cutoff voltage of lithium cobalt oxide (LCO) cathodes is an effective strategy to enhance the energy density of lithium-ion batteries (LIBs), while the formation of a poor cathode–electrolyte interphase (CEI) has limited their widespread application. Various electrolyte additives, part

Is lithium cobalt oxide a cathode?

While lithium cobalt oxide (LCO), discovered and applied in rechargeable LIBs first by Goodenough in the 1980s, is the most widely used cathode materials in the 3C industry owing to its easy synthesis, attractive volumetric energy density, and high operating potential [, , ].

What are lithium-ion batteries?

Lithium-ion batteries (LIBs) with the “double-high” characteristics of high energy density and high power density are in urgent demand for facilitating the development of advanced portable electronics.

Can licoo 2 be used in lithium-ion batteries?

Qian, J. et al. Electrochemical surface passivation of LiCoO 2 particles at ultrahigh voltage and its applications in lithium-based batteries. Nat. Commun. 9, 4918 (2018). Moon, S. H. et al. TiO 2 -coated LiCoO 2 electrodes fabricated by a sputtering deposition method for lithium-ion batteries with enhanced electrochemical performance.

Is licoo 2 a good battery cathode?

LiCoO 2 is a historic lithium-ion battery cathode that continues to be used today because of its high energy density. However, the practical capacity of LiCoO 2 is limited owing to the harmful phase transition at high voltages, which prevents the realization of its theoretical capacity.

What is LCO battery capacity?

LCO has a high theoretical capacity of 274 mAh g −1; however, its highly delithiated state (high cut-off voltage) degrades the battery performance, forcing recent LCO-based products to be used at 4.47 V for full cells, corresponding to a potential of ~4.55 V versus Li + /Li and a discharge capacity of 200 mAh g −1.
