      abstract     = {This study provides for the first time a detailed
                      investigation of the cold sintering of LiMn2O4 (LMO).
                      Aqueous based cold sintering aid facilitated densification
                      of LMO at lower temperature range of 400 °C to 600 °C
                      within a dwell time of merely 1 min to the relative density
                      of $70\%–80\%,$ without any non—stoichiometry or the
                      need of post annealing in air atmosphere. Connected porosity
                      was observed in the cold sintered structure as confirmed by
                      Mercury porosimetry and scanning electron microscopy
                      analysis. Cold sintered and dry milled LMO delivered a
                      specific discharge capacity of 121 mAh g−1 for the first
                      discharge cycle at 0.1 C with an appreciably low capacity
                      drop to 107 mAh g−1 at 15 C. In contrast, LMO powder,
                      without any cold sintering treatment, provided merely 84 mAh
                      g−1 at 0.1 C as initial discharge capacity and only 6 mAh
                      g−1 at 2 C. This difference was interpreted as the
                      removal/thinning of insulating Li2CO3 layer from the LMO
                      particles after being cold sintered as confirmed by X-ray
                      diffraction, thermal analysis and Raman spectroscopy.},
