“…The oxide sintering additive promotes liquid-phase sintering, accelerating the kinetics of densification compared with that of pure solid-state sintering. 43,44 The sintering additive Li 3 BO 3 (LBO) melts at approximately 800 1C, 45,46 whereby its liquid flows into the ceramic cathode composite matrix due to the capillary pressure difference between the fine and coarse channels of the solid cathode and electrolyte particle constituents. The capillary forces give rise to strong attractive forces between neighboring particles and rearrangement.…”

“…Sintering additives can help lower sintering temperature, enhance particle connectivity, and cathode/electrolyte interface densification [79] The addition of lithium borate (LBO) to LCO-and NMC-based composite cathodes, for example, lowers the sintering temperature from 1050 °C to 700 °C and accelerates densification kinetics. [42,87,88] Nonetheless, the addition of such additives could be detrimental to the cell performance as they increase the volumetric fraction of the "inactive" constituent in the composite cathode. Evidently, the utilization of ceramic components in composite cathodes creates major complications in terms of preparation methods and interparticle interfacial resistance.…”
