Effect of ball-milling on 3-V capacity of lithium . Ball-milling for a sufficient period of time of lithium-manganese oxide spinels, prepared either by a sol-gel method or by solid-state reaction, gave cathode materials of a lithium cell with excellent capacity retention in the 3-V range at room temperature and elevated temperatures despite an apparent Jahn-Teller distortion.
The mechanical stresses prevalent during ball milling may force the MnO2 nanorods to assume a minimum energy conﬁguration, aligning themselves X-OH þ Hþ ! X-OH2 þ ðpH < pHPZC Þ along the surface features of laterite particles so a to ‘‘survive’’ the At a pH value higher than pHPZC, the metal oxide surface could be repeated impacts.
