Stable all-solid-state lithium metal batteries with Li3N-LiF-enriched interface induced by lithium nitrate addition

Boron Nitride‐Based Release Agent Coating Stabilizes Li1.3Al0.3Ti1.7(PO4)3/Li Interface with Superior Lean‐Lithium Electrochemical Performance and Thermal Stability

“…This indicates strong chemical interaction between Li and BNRA, originated from the strong lithiophilicity of N atoms in BNRA. [ 38 ] The Li1s spectra also present the peak evolution from Li–Li (55.2 eV) to Li–N (54.8 eV) along with the depth change. [ 39 ] However, no shift and intensity change are observed for the characteristic B1s peak at 190.7 eV attributed to BN bond, suggesting no interaction between B and Li.…”

The multicomponent synergistic effect of a hierarchical Li0.485La0.505TiO3 solid-state electrolyte for dendrite-free lithium-metal batteries

“…According to previous reports, LiF with a lower surface transport energy barrier can effectively improve the mechanical strength of the SEI layer, enhance the diffusion rate of Li + , restrain the uncontrolled parasitic reactions. [47][48][49] Moreover, it can also depress the electron transport from the Li metal to the electrolyte and protects the Li metal anode interface. [50][51][52] Based on these advantages, the formation of LiF in the interphase may lead to the dendrite-free operation of the electrode.…”

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

“…The extra Li 2 S in the SEI is attributed to the reduction of SCP at the interface, 44 and this additive can also promote the dissociation of LiTFSI to form more LiF. 25 In addition, the XPS measurements of fresh and cycled PEO-5%SCP (aer 100 h, close to the Li anode side) membranes were carried out to investigate the variation of SCP during GCD process. Compared with the Li 1s peak for fresh PEO-5%SCP membrane (Fig.…”

“…Through adding fillers, the crystallinity of PEO can be destroyed to increase σ of resulting CPEs, but such operations are useless for enhancing the solid-electrolyte interphase (SEI) for Li dendrite suppression. 23 To overcome this issue, some special fillers have been developed to stabilize the interface of Li metal anode and solid electrolyte, such as Li 2 S, 24 LiNO 3 , 25 LiF, 26 Li 2 S 6 , 27 and AlF 3 . 28 These additives can be involved in SEI generation, or promoting the decomposition of Li salts, and finally, robust SEIs can be formed to suppress the Li dendrite.…”
