However, the spontaneous chemical reactions at the interface between SSEs and Li metal limit the lifespan of all−solid−state Li metal batteries (ASSLMBs). Herein, an electronic structure modulation strategy is proposed to stable the Li−argyrodite Li₆PS₅Cl SSEs with Li metal via doping fluorine and calcium atoms. Mechanistic studies reveal that the electronic−withdrawing F atoms in the PS₄ units enhance the hybridization of P 3p−S 3p orbital via modulating the electronic distribution of P sites, while the substitution of Ca atoms in the P sites induces the electron enrichment of S sites to form a stable CaS₄ unit. As a result, the critical current density of designed Li_6.05P_0.95Ca_0.05S_4.9F_0.1Cl SSEs is extended to 1.6 mA cm⁻², which is three times higher than Li₆PS₅Cl SSEs.

In this work, a Na₃SbS₄ solid electrolyte with coexisting W and F dopants (Na_2.804Sb_0.879W_0.046S_3.7F_0.075) is synthesized and achieves a high ionic conductivity of 11.13 mS cm⁻¹. Density-functional-theory calculations indicate that both the reduced Na-vacancy formation energy and Na-ion diffusion barrier by such co-doping strategy contribute to the improved ionic conductivity. Furthermore, although the promoted H₂O dissociation by W doping results in the extremely low stability of Na_2.95Sb_0.95W_0.05S₄ in moisture, the added F dopant dramatically increases the energy costs for H₂O adsorption and dissociation, effectively inhibiting the hydrolysis of Na_2.804Sb_0.879W_0.046S_3.7F_0.075.

However, the practical implementation of thin Li anodes is significantly challenged by the inevitable formation of lithium dendrites, as well as the lithium depletion caused by interfacial side reactions. To address this, we propose a lumped Li-Gr@MgF₂ (LGMF) anode comprised of lithiated MgF₂-coated graphite, which precisely reconstructs the lean-lithium metal anode through bottom-up integration. Finely optimized electrode units of LiC₆-LiMg/LiF possess lithiophilic Li-Mg alloy and high-interface-energy LiF interfacial modification, which regulate the lithium-ion flux and effectively suppress dendrite growth. Assembling electrode units collaboratively establishes the ion-electron percolating network within the LGMF, fully activating the entire anode. The optimized LGMF anodes extend the longevity of carbonate-based quasi-solid-state symmetric cells to 2400 h at 0.2 mA cm⁻²/0.2 mAh cm⁻², even under limited lithium conditions.

The thermoelectric effect of this ionic thermoelectric gelatin is mainly achieved through the synergy of the thermodiffusion effects and the thermogalvanic effect of ions. In addition, by applying pressure, the thermoelectric effect of this ionic thermoelectric gelatin can be changed (the thermopower of the ionic thermoelectric gelatin increases from 1.21 mV/K to 1.67 mV/K, representing a 38 % increase), so as to enable the sensor to sense external forces.
