LiCoMnO4 was made at 550 degrees C in 2 h using a novel biotemplating synthetic methodology. High temperature heat treatment under flowing N-2 was then used to prepare the cation-disordered rock salt, LiCoMnO3. We demonstrate for the first time that both phases can operate as conversion anodes in lithium-ion batteries, operating at 0.7 V with specific capacities of similar to 400 mAh g(-1). We also demonstrate that 1,3-propane sultone can be used as an electrolytic additive to provide a modest boost to specific capacity in cells cycled at high potentials with LiCoMnO4 as the cathode.
