Abstract

Precise knowledge of the discharge and charge reactions within Li–O₂ batteries is an important aspect of developing highly efficient, rechargeable Li–O₂ cells. We describe an analytical method capable of determining the quantity of Li₂O₂ in the cathode on the basis of the reaction of Li₂O₂ with an oxoammonium salt.
