Low-voltage intercalation anodes for lithium batteries are important for future applications in portable electronics and electric vehicles. Using a combination of computational methods along with powder X-ray- and neutron-diffraction techniques, the intercalation process for Li1+xV1−xO2, in particular the key role of non-stoichiometry in switching on intercalation, is clarified.
