“…Therefore, on the side of PEO-based composite electrolytes, the migration of lithium ions occurs mainly through the PEO matrix, SN plastic crystal, LLZTO ionic conductor, the interfaces between PEO and LLZTO, as well as between SN and LLZTO. [11,[58][59][60] On the PAN side, together with Figure 5c, it can be seen that the PEO-based composite electrolyte passes across the PAN fiber network and the uniform distribution of LLZTO particles can be also observed, indicating that the voids between the fibers are filled and connected to each other, forming a continuous lithium-ion transmission channel. LLZTO dispersed in the fiber network can not only fix anions but also facilitate ion migration.…”

such as leakage, corrosion, swelling, and flammability. [3,4] Therefore, developing non-flammable solid electrolytes to replace traditional organic electrolytes has become the focus of this field. [1,2,5] Meanwhile, lithium metal, with the lowest potential (−3.04 V vs standard hydrogen electrode) and high theoretical capacity (3860 mA h g −1 ), has the potential as anodes for solid-state batteries and greatly improves the energy density. [6][7][8] Solid electrolytes, regarded as the most important core of solid-state batteries, could be roughly divided into three categories: inorganic solid electrolytes (ISEs), solid polymer electrolytes (SPEs), and composite polymer electrolytes (CPEs). [5,[9][10][11] ISEs exhibit high ionic conductivity and a wide electrochemical stability window, while their rigidity restricts close contact with electrodes, which leads to interface problems between ISEs and electrodes. [12][13][14] SPEs, based on Li + immigration in polymers, have considerable advantages over ISEs, such as low cost, easy preparation, high flexibility, and especially good ability to form closer contact with electrodes. However, the ionic conductivity of SPEs is quite low at room temperature. [11,15] Meanwhile, the low ionic transference number of SPEs (< 0.4) is supposed to be the positive incentive of dendrite growth. [16][17][18] At present, researchers improve the ionic conductivity mostly by increasing the proportion of amorphous regions, such as cross-linking, forming copolymers, and adding plasticizers. [19][20][21][22] As ISEs and SPEs mentioned above have different advantages and disadvantages, CPEs could combine the superior properties of inorganic ceramics and polymer matrixes, and not only improve the mechanical properties and ionic conductivity at room temperature over SPEs, but also enhance the interface contact over ISEs. [23][24][25][26][27][28] Therefore, CPEs have been attracting more research interest.CPEs are solid conductors consisting of inorganic fillers dispersed in solid polymer hosts. Inorganic fillers could be generally divided into two kinds, non-lithium conductors (such as TiO 2 and SiO 2 ) and lithium-ion conductors (such as garnet-type Li 7 La 3 Zr 2 O 12 (LLZO), perovskite-type Li 3x La 2/3-x TiO 3 (LLTO), NASICON-type Li 1+x Al x Ti 2-x (PO 4 ) 3 (LATP), and sulfide Li 10 GeP 2 S 12 (LGPS)). [27,[29][30][31][32][33][34][35][36][37] Generally, compared with nonlithium-ion conductors, lithium-ion conductors could provide more lithium-ion transmission channels and thus improve the ionic conductivity. [11,24] Among them, LLZO, LLTO, LATP, and LGPS are four representative well-studied solid electrolytes.

“…The C 1s spectra apparently show four characteristic peaks, of which the one at 284.8 eV arises from the adventitious carbon. The peaks at 286.59 and 289.47 eV correspond to the C–O bond in PEO and CO 3 2– , respectively . The existence of CO 3 2– may arise from the Li 2 CO 3 due to the surface passivation of the LLZTO filler with CO 2 while handling in air .…”

Heightened attention for solid-state Li–O2 batteries (SSLOBs) exists due to their improved safety, wider electrochemical window, and high energy density in addition to the solid electrolyte’s innate capability of suppressing Li dendrite penetration and shielding the Li metal anode from oxygen, CO2, and moisture in the air, in comparison with the conventional Li–O2 batteries using liquid organic electrolytes. Herein, a cathode supported quasi-SSLOB with an integrated composite polymer-based architecture (ICPA) is developed with reduced interfacial resistance, extended triple-phase boundaries (TPBs) for Li–O2 reactions, and a thin film solid-state electrolyte. The Li–O2 cell with ICPA (denoted as ICPA cell) exhibits a lower charge transfer impedance than its counterpart with the same composite polymer electrolyte (CPE) but a nonintegrated structure (termed the CPE cell). The former shows reduced interfacial impedance between electrolyte and cathode and increased TPBs. Furthermore, the ICPA cell delivers higher discharge capacity, lesser capacity decay, and significantly lower impedance rise after cycles than the CPE cell, ascribed to the continuous Li-ion transport in ICPA and the resulting more efficient discharge and charge processes. Under a limited capacity cycling protocol of 300 mAh g–1, the ICPA cell achieves excellent reversibility for 78 cycles, remarkably surpassing the CPE cell which only performs 44 cycles in addition to showing half of the after-cycle impedance compared to that for the CPE cell. Nonetheless, the same composite polymer electrolyte used for both CPE- and ICPA-based cells demonstrates excellent stability toward Li metal after long-term cycling. These findings manifest that the design and application of cathode supported SSLOB with ICPA can be a promising approach to achieve high-performance Li–O2 batteries.
