Manufactured by Merck Group
Visit Supplier

LiCoO2 is a lithium cobalt oxide material used in the production of rechargeable lithium-ion batteries. It serves as the cathode active material in these batteries. The core function of LiCoO2 is to facilitate the reversible insertion and extraction of lithium ions during the charging and discharging processes of the battery.

The Li excess Li1+xCoO2 targets were prepared by sintering a mixture of high purity LiCoO2 (Sigma-Aldrich) and 10% excess Li2O (Alfa Aesar) powders to compensate for Li loss during deposition. The mixed powders were ball milled for 72 h and dried at 80 °C for 2 h. The targets pressed into 1-inch diameter were sintered at 400 °C for 2 h and 1000 °C for 10 h.

Synthesis and Characterization of Oxygen- and Hydrogen-Annealed Li4Ti5O12

Check if the same lab product or an alternative is used in the 5 most similar protocols
The following active materials were employed in this work: Li4Ti5O12 (D50 1.9 μm) from MTI Corporation, LiCoO2 (7–10 μm) from Sigma–Aldrich, and anatase TiO2 (<10 nm) from Sachtleben Chemie. All components of the electrolyte, namely ethylene carbonate and dimethyl carbonate and LiPF6, and metallic lithium were purchased from Sigma–Aldrich (battery grade). Celgard 2500 and Ketjenblack EC-600 JD were courtesy of Azelis and AkzoNovel Polymer Chemicals.
The oxygen-annealed Li4Ti5O12 samples (O_LTO) were obtained by treatment commercially available Li4Ti5O12 (P_LTO) in flowing O2 (100 vol %) at 650 °C for 120 min. The O2-annealed sample (O_LTO) was then treated in flowing H2 (5 vol % in Ar) at 650 °C for 90 min to obtain hydrogen-annealed Li4Ti5O12 (H_LTO).

Controlled Chemical Delithiation of LiCoO2 Cathode

Check if the same lab product or an alternative is used in the 5 most similar protocols
Commercially available LiCoO2 (Sigma Aldrich No: 442704-100G-A) here named as LCO0 was used. The chemically delithiated samples (namely LCO1, LCO2, LCO3, LCO4, LCO5, LCO6, LCO7 and LCO8) are prepared by stirring 5 g (LCO0) in 500 ml solution. The treating times, concentration of solutions, supernatant and chemical composition after delithiation are presented in Table 1. Acid solutions were prepared by diluting conc. HCl (37%) in milliQ deionised water. After this treatment, the filtered samples were washed several times with copious amounts of milliQ deionised water to remove all possibly formed LiCl and CoCl2 before drying at 100 °C.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
