Abstract
As global energy consumption continues to rise, the importance of energy storage becomes increasingly important. Energy density, rate-capability, and cyclability must continually improve. This constant struggle for advancement is seen most easily in the high-density, electrical energy storage market, which is dominated by lithium-ion batteries. One of the most promising chemistries in lithium-ion batteries is LiMn2O4 (LMO), a spinel cathode material which has the advantage of both a high energy density and a high rate capability, but this chemistry is plagued with cyclability problems. In the LMO system the main contributor to cycling degradation is the Mn disproportionation reaction (2Mn = Mn + Mn) which creates soluble Mn that is lost to solution. This loss of active material from LMO leads to capacity degradation. In order to understand exactly how LMO loses active material from its surface, it is crucial to determine the surface’s atomic structure. This is because the surface structure dictates how the electrolyte will interact with the cathode.
