Abstract
Electrodes containing lithium phosphate derivative materials and batteries with such electrodes are provided. The lithium phosphate derivative compounds contain an anionic framework capable of conducting lithium ions and have an activation energy from 0.2 to 0.45 eV and conductivities from 0.01 to 10 mS/cm at 300K. Materials of specific formulae are provided and methods to alter the composite materials with inclusion of aliovalent ions shown.
