Mixing sacrificial additives with active materials is a typical in situ approach, which depends on electrochemical oxidation of additives to compensate the Li loss.[15,16] However, this method inevitably leads to electrode volume variation and inactive residues in the cell. Ex situ prelithiation includes electrochemical prelithiation and chemical prelithiation. The former method requires disassembling and reassembling of batteries, which precludes its practical application.[17,18] Alternatively, chemical prelithiation approach is the direct contact between TI - Constructing a Robust Solid–Electrolyte Interphase Layer via Chemical Prelithiation for High‐Performance SiOx Anode JF - Advanced Energy and Sustainability Research DO - 10.1002/aesr.202200083 DA - 2022-10-01 UR - https://www.deepdyve.com/lp/wiley/constructing-a-robust-solid-electrolyte-interphase-layer-via-chemical-9qsWuAJQdp VL - 3 IS - 10 DP - DeepDyve ER -
