Abstract
Provided are processes of removing lithium from an electrochemically active composition. The process of removing lithium from an electrochemically active composition may include providing an electrochemically active composition and combining the electrochemically active composition with a strong oxidizer optionally at a pH of 1.5 or greater for a lithium removal time. The electrochemically active composition may include Li, Ni, and O. The electrochemically active composition may optionally have an initial Li/M at % ratio of 0.8 to 1.3. According to some embodiments of the present disclosure, the lithium removal time may be such that a second Li/M at % ratio following the lithium removal time is 0.6 or less, thereby forming a delithiated electrochemically active composition.
