Abstract
High voltage cells containing LiCoO2 as the cathode mate!!!! known to lose capacity on open circuit storage at room tempers above in methyl formate-based electrolytes2. This capacity lob ascribed to the strain placed on the LiCoO2 lattice as x O.5 as the slow, irreversible oxidation of the electrolyte at poter excess of 4. 2V. This proposal addresses the stabilization of m the addition of novel adducts to the crystal lattice. Additionally methyl formate-based electrolyte stable to potentials approach will be used in conjunction with the doped cobaltates. The goal of the Phase I effort is to deliver Li/LiCoO2 coin cell hardware to the Navy containing these advanced battery materials.
