dc.description.abstract | The cycling performance of LiCoPO4 (LCP) as a high voltage positive electrode material in lithium‐ion batteries is enhanced by partial magnesium substitution for cobalt. Structural investigation of magnesium‐doped LCP using combined powder neutron and X‐ray diffraction reveals a decrease in anti‐site defects. In addition, the reduced unit cell volume variation during the charging process is observed by operando X‐ray diffraction measurements. Characterisation of the surface shows the presence of a Mg‐rich layer on the surface that might prevent detrimental reactions with the electrolyte. The combined beneficial effects of magnesium doping in LCP result in improved capacity retention. | |
