      abstract     = {Silica (SiO2) anodes are promising candidates for enhancing
                      the energy density of next-generation Li-ion batteries,
                      offering a compelling combination of high storage capacity,
                      stable cycling performance, low cost, and sustainability.
                      This performance stems from SiO2 unique lithiation
                      mechanism, which involves its conversion to electroactive
                      silicon (Si) and electrochemically inactive species.
                      However, widespread adoption of SiO2 anodes is hindered by
                      their slow initial lithiation. To address this, research has
                      focused on developing electrochemical “activation
                      protocols” that involve prolonged low-potential holding
                      steps to promote SiO2 conversion. Despite these efforts, the
                      complex and multi-pathway nature of SiO2 lithiation process
                      remains poorly understood, impeding the rational design of
                      effective activation strategies. By introducing a
                      multi-probe characterization approach, this study reveals
                      that, contrary to the previously proposed reaction mechanism
                      of SiO2 anodes, the lithiation process initiates at low
                      potentials with the direct formation of Li4SiO4 and LixSi.
                      Electrochemical activation potential was found to
                      significantly influence the degree of conversion, with
                      10 mV identified as the optimal cut-off potential for
                      maximizing SiO2 utilization. These findings provide key
                      enablers to unlock the full potential of SiO2 anodes for
                      battery technology.},
