The practical application of silicon (Si) anodes is limited by the large volume change, unstable solid electrolyte interface (SEI), and low intrinsic conductivity. To address these challenges, we designed Pre-lithiated poly(acrylic acid)-boric acid (LiPAA-BA) a multifunctional binder with a 3D network structure, using a combined pre-lithiation and cross-linking strategy. LiPAA-BA showed a high interfacial adhesion force (4.8 N), which was improved by about 2 times compared to conventional PAA due to the increased number of contact sites with the silicon and the 3D network structure. As a result, the Si@LiPAA-BA electrode achieved an excellent capacity retention of 100% after 300 cycles and volume expansion was effectively suppressed. LiPAA-BA contains a lithium conducting group, which increases the lithium diffusion coefficient (DLi+) compared to PAA by a 1.6 times and enhances the rate capability. The crosslinker (BA) adopted in this study contains boron atoms with electron-deficient properties, which enabled the formation of a stable SEI layer on the silicon surface through interaction with anions in the electrolyte. A full cell using a SiOx@C anode with a LiPAA-BA and an LFP cathode showed 64.89% capacity retention at 50 cycles, demonstrating potential for practical application.
