LZSP powder—cataloged under commercial trade labels as "Li3Zr3Si3PO12" but crystallographically defined as the solid-solution NASICON composition Li3Zr2Si2PO12 (x = 2 in the Li{1+x}Zr2SixP{3-x}O12 series)—is a lithium-ion conducting ceramic solid-state electrolyte. Its primary utility lies in providing a titanium-free, low-density NASICON framework that circumvents the rapid electrochemical reduction seen in traditional titanium-based NASICONs (such as LATP) while offering superior ambient air/moisture stability compared to garnet-type oxides (LLZO).
The primary applications in battery systems are: (1) Active Ceramic Filler in Composite Polymer Electrolytes (CPEs): Sub-micron LZSP powder (D50=~ 0.3–0.8 um) is blended at loadings of 10–40 wt% into polymer matrices such as PEO, PVDF-HFP, or poly(acrylonitrile) (PAN). It disrupts polymer chain crystallinity to promote segmental motion, provides high-mobility Lewis acid-base interfacial pathways, and reinforces mechanical stiffness against soft dendrite deformation. (2) Tape-Cast Composite Separator Films: Slurry-cast onto release liners with polymeric binders (e.g., poly(acrylic acid) or PVDF) to form ultrathin (15–30 um), flexible solid-state separator sheets. (3) Inorganic Catholyte for Composite Cathodes: Milled dry with cathode active materials (CAMs like LFP or high-Ni NMC) and conductive carbon to create continuous 3D inorganic Li+ percolation channels inside high-loading positive electrodes.
