Asynchronous Crystal Cell Expansion during Lithiation of K + -Stabilized α-MnO 2

alpha-MnO2 is a promising material for Li-ion batteries and has unique tunneled structure that facilitates the diffusion of Li+. The overall electrochemical performance of a-MnO2 is determined by the tunneled structure stability during its interaction with Li+, the mechanism of which is, however, po...
