      abstract     = {Very high theoretical specific energies and abundant
                      resource availability have emerged interest in primary
                      Si–air batteries during the last decade. When operated
                      with highly doped Si anodes and EMIm(HF)2.3F ionic liquid
                      electrolyte, specific energies up to 1660 Wh kgSi−1 can be
                      realized. Owing to their high-discharge voltage, the most
                      investigated anode materials are ⟨100⟩ oriented highly
                      As-doped Si wafers. As there is substantial OCV corrosion
                      for these anodes, the most favorable mode of operation is
                      continuous discharge. The objective of the present work is,
                      therefore, to investigate the discharge behavior of cells
                      with ⟨100⟩ As-doped Si anodes and to compare their
                      performance to cells with ⟨100⟩ B-doped Si anodes under
                      pulsed discharge conditions with current densities of 0.1
                      and 0.3 mA cm−2. Nine cells for both anode materials were
                      operated for 200 h each, whereby current pulse time related
                      to total operating time ranging from zero (OCV) to one
                      (continuous discharge), are considered. The corrosion and
                      discharge behavior of the cells were analyzed and anode
                      surface morphologies after discharge were characterized. The
                      performance is evaluated in terms of specific energy,
                      specific capacity, and anode mass conversion efficiency.
                      While for high-current pulse time fractions, the specific
                      energies are higher for cells with As-doped Si anodes, along
                      with low-current pulse fractions the cells with B-doped Si
                      anodes are more favorable. It is demonstrated, that
                      calculations for the specific energy under pulsed discharge
                      conditions based on only two measurements—the OCV and the
                      continuous discharge—match very well with the experimental
                      data.},
