“…Monoclinic-KFeHCF displays flat potential plateaus for galvanostatic K + extraction/insertion through two-phase reactions. In contrast, cubic-KFeHCF has tangential curves via a single-phase regime verifying superior potential stabilities for K. [457] Theoretical calculations verify crystal structures, cation-anion interactions, and defects influence the interface transport for borohydride SEs//K.

Solid‐state batteries (SSBs) have received significant attention due to their high energy density, reversible cycle life, and safe operations relative to commercial Li‐ion batteries using flammable liquid electrolytes. This review presents the fundamentals, structures, thermodynamics, chemistries, and electrochemical kinetics of desirable solid electrolyte interphase (SEI) required to meet the practical requirements of reversible anodes. Theoretical and experimental insights for metal nucleation, deposition, and stripping for the reversible cycling of metal anodes are provided. Ion transport mechanisms and state‐of‐the‐art solid‐state electrolytes (SEs) are discussed for realizing high‐performance cells. The interface challenges and strategies are also concerned with the integration of SEs, anodes, and cathodes for large‐scale SSBs in terms of physical/chemical contacts, space‐charge layer, interdiffusion, lattice‐mismatch, dendritic growth, chemical reactivity of SEI, current collectors, and thermal instability. The recent innovations for anode interface chemistries developed by SEs are highlighted with monovalent (lithium (Li+), sodium (Na+), potassium (K+)) and multivalent (magnesium (Mg2+), zinc (Zn2+), aluminum (Al3+), calcium (Ca2+)) cation carriers (i.e., lithium‐metal, lithium‐sulfur, sodium‐metal, potassium‐ion, magnesium‐ion, zinc‐metal, aluminum‐ion, and calcium‐ion batteries) compared to those of liquid counterparts.

“…4,[12][13][14][15] A redox-active inorganic material, which is widely used as an electrode material for rechargeable batteries, is inserted as the solid-contact (SC) layer that acts as an internal reference electrode and internal solution, thereby significantly improving the potential stability. [16][17][18][19][20][21][22][23][24] However, the cause of this potential stabilization is still not clear, as there are two possible mechanisms for this effect: 1) redox-active materials act as an internal reference electrode and 2) stabilization of the membrane potential by solid-contacting potassium-containing materials. Although solid electrolytes used in all-solid-state batteries are ion conductors, they are redox-inactive and have low electronic conductivity as the electrolytes need to maintain stable separation between the positive and negative electrodes in the battery configuration.…”

Solid electrolytes used in all-solid-state batteries electronically separate the positive and negative electrodes in the battery and only allow the carrier ions to pass through. KTiOPO4 (KTP), a potassium ion-conducting solid electrolyte, was first applied as the inner solid contact layer of an all-solid-state potassium ion-selective electrode (ISE) to stabilize the membrane potential. Application of the KTP layer improved the long-term potential stability of the ISE by stabilizing the membrane potential. This can be further improved by adding acetylene black (AB) to the KTP layer which reduced the electrode resistance owing to its high double-layer capacitance.
