Abstract

Alternative solid electrolytes are the next key step in advancing lithium batteries with better thermal and chemical stability. A soft solid electrolyte, (Adpn)2LiPF6 (Adpn, adiponitrile), is synthesized and characterized that exhibits high thermal and electrochemical stability and good ionic conductivity, overcoming several limitations of conventional organic and ceramic materials. The surface of the electrolyte possesses a liquid nano-layer of Adpn that links grains for a facile ionic conduction without high pressure/temperature treatments. Further, the material can quickly self-heal if fractured and provides liquid-like conduction paths via the grain boundaries. A substantially high ion conductivity (~10−4 S cm–1) and lithium-ion transference number (0.54) are obtained due to weak interactions between ‘hard’ (charge dense) Li+ ions and the ‘soft’ (electronically polarizable) –C≡N group of Adpn. Molecular simulations predict that Li+ ions migrate at the co-crystal grain boundaries with a (preferentially) lower activation energy Ea and within the interstitial regions between the co-crystals with higher Ea values, where the bulk conductivity is a smaller but extant contribution. These co-crystals establish a special concept of crystal design to increase the thermal stability of LiPF6 by separating ions in the Adpn solvent matrix, and also exhibit a unique mechanism of ion conduction via low-resistance grain boundaries, which contrasts with ceramics or gel electrolytes.

Extended data

Extended Data Fig. 1 TGA data of (Adpn)2LiPF6, LiPF6 and Adpn.

LiF remains at 800 oC for LiPF6 and (Adpn)2LiPF6. For Sample 1, a typical TGA pan (open) with N2 purge was used. For Sample 2, a punch-holed Tzero aluminium pan (used in DSC) was used to avoid excessive removal of Adpn from crystals due to N2 purge. The sample 2 shows a Td at 200 oC, higher than the Tm = 180 oC from DSC (Fig. 2a).

Extended Data Fig. 2 Snapshots of (Adpn)2LiPF6 cocrystals after an equilibration of 10 ns (every temperature) using model V.

(a) 300 K, (b) 400 K and (c) 500 K. Li–N(Adpn) coordinated networks are shown as yellow tetrahedrons and PF6− anions are shown as red octahedrons. Adpn solvent is shown as line representations. (d) Non-bonded interaction energy vs. temperature during the simulated heating of (Adpn)2LiPF6 cocrystals in model V. The liquid-like surface-layer is shown in a cyan ring in (c).

Extended Data Fig. 3 SEM SE images of (Adpn)6LiPF6 at different magnifications taken at RT.

(a, b, c) pressed pallets; (d, e) pressed pallets quenched in liquid N2; (f) pressed pellet that has been quenched in liquid N2 so that some grain boundaries broken; (g, h, i) powders, fusion between the grains can be observed by comparison between powders and powders pressed to make pellets; even in powder, there can be connection between the grains (i); in the pressed pellet the large grains contain smaller crystallites and there are needle-like structures between the grains; (j, k, l) samples synthesized in glass fiber.

Extended Data Fig. 4 SEM SE images of (Adpn)6LiPF6 after cycling.

Post-mortem (30 days to failure) SEM images after Li plating/stripping of Li0/(Adpn)2LiPF6/Li0 showing places where the (Adpn)2LiPF6 cocrystal still adhered to the Li0, and the SEI layer at three magnifications (a-c); (d) edge of Li0 metal showing thin SEI layer.

Extended Data Fig. 5 SEM EDX spectra of (Adpn)6LiPF6 post-mortem.

(a) and (b) are EDX spectra taken at positions 2 and 4, respectively, in Extended Data Fig. 4a, which show places where the (Adpn)2LiPF6 cocrystal still adhered to the Li0, as indicated by strong C, F, N and P signals; (c) – (g) are EDX spectra taken at positions 5, 6, 7, 8 and 9 in Extended Data Fig. 4b-c, which show SEI layer dominated by strong O and C signals; (h) Atom % for EDX spectra.

Extended Data Fig. 6 Additional electrochemistry data.

(a) Representative constant phase-element (CPE) circuit; (b) Li+ ion transference number (tLi+) measured after stabilization of the impedance; t+Li = 0.54; a zoomed-in view of Fig. 4d, Li plating, 2 h charge/discharge cycles at (c) J = 0.05 mA/cm2 for 60 cycles, (d) J = 0.1 mA/cm2 for 60 cycles; (e) Discharge capacity as a function of C rate for a Li0/(Adpn)2LiPF6/LiFePO4 half-cell #1 at RT, 2 h charge/2 h discharge cycles. The cell did not recover after C/2; (f) Discharge capacity as a function of C rate for a Li0/(Adpn)2LiPF6/LiFePO4 half-cell #2 at 10 °C, 2 h charge/2 h discharge cycles. The cell recovered after 1 C. At high charge/discharge rates (1 C), the capacity drops to zero since at 10 °C the grain boundary region is close to the freezing point of the “free” Adpn in the (Adpn)2LiPF6 cocrystals, possibly preventing growth of Li dendrites through the grain boundaries; (g) Capacity and Coulombic efficiency of LTO/(ADN)2LiPF6/NMC622 cells at 25 °C at C/10 rate as a function of cycle number, 2 h charge/2 h discharge where two cycles of preconditioning at C/40 rate were performed; (h) Impedance spectra before and after the full cell cycling at RT, two semicircles represent interfacial resistance at the Li anode and LiFePO4 cathode. Impedance increases after the cycling; (i) Impedance spectra (Nyquist plots) over time for NMC-622/(Adpn)2LiPF6−glass fiber/NMC-622 (1 MHz – 0.01 Hz), a zoomed in view is shown inset.

Extended Data Fig. 7 Electronic structure interpretation of redox stability of cocrystals.

(a) Density of states (DOS) for (Adpn)2LiPF6. Solid lines show p-orbital densities for optimized structure of (Adpn)2LiPF6: [Adpn2LiPF6]opt. Dotted lines show the effect of one electron addition; after addition of the electron, the structure was optimized and then this ‘excess’ electron was removed to calculate DOS from SCF (without optimizing the structure): [{(Adpn2LiPF6)−1opt}-e-]scf; Differential Electron density map (ρe-[Adpn2LiPF6]opt-ρe-[{(Adpn2LiPF6)−1opt}-e-]scf) showing the effect of addition of an electron to a unit cell of (Adpn)2LiPF6 - (b) in the plane perpendicular to c-crystallographic direction and (c) in the plane perpendicular to b-crystallographic direction. Close to Li+•••CN: blue lobes are larger compared to red, suggesting greater change in the electron density close to C≡N compared to P—F, on the addition of electron.

Extended Data Fig. 8 Average mean squared displacement of constituent Li+ ions, PF6−, ions and Adpn molecules in model V2g,sol.

(a) 300 K, (b) 325 K, and (c) 350 K. The calculated diffusion coefficients are provided in Supplementary Table S2.
