Dry electrode technology, the rising star in solid-state battery industrialization

High Air Stability and Excellent Li Metal Compatibility of Argyrodite‐Based Electrolyte Enabling Superior All‐Solid‐State Li Metal Batteries

“…[ 7,8 ] Especially, the inherently soft property of SSEs is conducive to forming an intimate solid–solid interface contact in ASSLMBs via simple cold pressing technology at room temperature, which avoids the complicated high‐temperature sintering process and tremendously improves machinability, and thus SSEs are optimal candidates for use in ASSLMBs at present. [ 9 ]…”

“…[ 13 ] Even more worrying is that the complicated postprocessing technic and atmosphere control will greatly increase manufacturing costs, thus obstructing the commercialization progress of SSEs. [ 9,14 ] The other daunting challenge is the poor interface compatibility because SSEs are prone to (electro)chemical reduction from the Li metal anode. [ 15,16 ] Moreover, that reduction reaction would cause uneven Li + deposition and thus result in the formation of Li dendrite at anode interface, which would penetrate through the SSEs and deteriorate the performance and lifetime of batteries.…”

LiNi0.5Mn1.5O4 cathode microstructure for all-solid-state batteries

“…To demonstrate the benefits of H-LNMO in a realistic cathode configuration, a film-type composite cathode was fabricated by a polytetrafluoroethylene (PTFE)-based dry processing method [47]. The fibrous network produced by PTFE under the shear stress of repeated grinding steps forms a cohesive composite cathode with good ionic and electronic transport [48,49]. Figures 4a-b display the GCD curves of Al 2 O 3 -H-LNMO/LPSCl/Li-In with pellet type-and film type-composite cathodes, respectively.…”

A sulfur-containing polymer-plasticized poly(ethylene oxide)-based electrolyte enables highly effective lithium dendrite suppression

“…The crucial component of ASSLMBs is solid electrolytes, which can be classied into inorganic electrolytes (such as oxides, suldes, and halides) and solid polymer electrolytes (SPEs). [1][2][3][4][5] Among these electrolytes, SPEs, which contain polymer matrixes and Li salts, have aroused broad interest due to their intrinsic advantages, e.g., high exibility, seamless interface with electrodes, lightweight, non-toxicity, low cost, and large-scale preparation. 6,7 As is well known, poly(ethylene oxide) (PEO), poly(methyl methacrylate), polyacrylonitrile and poly(vinylidene uoride) have been widely employed as polymer matrixes for SPEs.…”
