Patent ID: 7776478

Claim:
A battery cell having a negative electrode, a positive electrode, and an electrolyte structure, wherein the negative electrode includes a first LiPON layer covering at least a portion of the negative electrode and having randomly spaced defects; the positive electrode includes a cathode material and a second LiPON layer covering at least a portion of the positive electrode and having randomly spaced defects; and the electrolyte structure includes a polymer electrolyte material sandwiched between the LiPON layer of the negative electrode and the LiPON layer of the positive electrode, wherein the randomly spaced defects in the first and second LiPON layers are at least partially filled by the polymer electrolyte material and wherein the polymer electrolyte layer fixes defects in at least one of the LiPON layers, wherein the polymer electrolyte layer includes a gel.
