Rechargeable silver vanadium oxide cells

The use of SVO as a rechargeable cathode material is enticing due to the high-energy density (> 300 mAh/g) of this material. However, during the discharge reaction of a lithium/SVO cell, the reduced silver is replaced by lithium in the vanadium oxide matrix. Therefore, the reversibility of this lithium for silver substitution under charge conditions is still a matter of debate, as will be outlined below.
