Cu Doping-Enabled Control of Grain Boundary Fusion and Particle Size in Single-Crystal LiNi_0.5Co_0.2Mn_0.3O₂ Cathode Materials

Batteries
Copper (Cu) doping is recognized as an effective strategy to enhance the electrochemical properties of LiNi1−x−yCoxMnyO2 (NCM) cathode materials. However, the influence of Cu2+ doping on particle size and grain boundary fusion remains insufficiently ...

Mathematics preparation of engineers

, 2009
Abstract The place to be given to mathematics in the preparation of engineers for meeting their professional needs is the aim of our research, which relies on the anthroplogical theory of didactics. The text of the thesis begins by an historical enquiry relying on the history of the Ecole Polytechnique and on the activities of the CIEM (ICMI), since ...
