Area of Science:

  • Materials Science
  • Electrochemistry
  • Energy Storage

Background:

  • All-solid-state batteries (ASSBs) offer high energy density and safety but face challenges with solid-solid interfaces and anode degradation.
  • Micro-sized silicon (µSi) anodes, promising for high capacity, suffer from large volume changes and poor interfacial contact during cycling.

Purpose of the Study:

  • To develop an interfacially reinforced crosslinked binder (IRCB) for stabilizing µSi anodes in ASSBs.
  • To address both mechanical integrity and interfacial stability issues in µSi anodes.

Main Methods:

  • Synthesized IRCB via crosslinking 1,4-butanediol diglycidyl ether and ethylenediamine, creating a 3D polymer network.
  • Fabricated carbon-free µSi anodes using the IRCB binder.
  • Evaluated electrochemical performance and interfacial stability with sulfide solid electrolytes.

Main Results:

  • IRCB-based µSi anodes demonstrated 90% capacity retention after 300 cycles at 1 C, a significant improvement over conventional PVDF binders (16% retention).
  • The 3D polymer network enhanced mechanical constraint, maintained interparticle contact, and facilitated Li+ transport.
  • IRCB effectively mitigated particle displacement and suppressed interfacial degradation with sulfide solid electrolytes.

Conclusions:

  • Rational binder engineering with IRCB is crucial for achieving stable and high-performance µSi anodes in ASSBs.
  • IRCB successfully overcomes the limitations of solid-solid interfacial contact and chemomechanical degradation in µSi anodes.
