“…This means that the ionic conductivity of PEO-based SPEs is still unsatisfactory for use in practical applications due to the crystallization tendency of the polymer chains at an ambient temperature (∼10 –5 to 10 –3 mS·cm –1 ). Correspondingly, the introduction of plasticizers and fillers has been widely proposed as common strategies to tackle the poor ionic conductivity of SPEs …”

Polyethylene oxide (PEO)-based structures integrated with filler nanoparticles are known as a potential promising electrolyte applicable for developing all-solid-state lithium secondary batteries for solving the challenging obstacle of low ionic conductivity. In this direction, for the first time, this research investigated resorcinol formaldehyde@Fe 3 O 4 core−shell structures decorated by Ni nanoparticles, which were efficiently synthesized using a feasible method (indicated as NiNP@RF@Fe 3 O 4 ). The favorable characteristics of the PEO-based polymeric films embedded with NiNP@RF@Fe 3 O 4 particulate fillers were explored using appropriate analytical tools. It is observed that the polymeric electrolyte filled with the nanoparticles represented a rougher surface with more pores, greater ion pair dissociation, fewer crystalline domains, and superior thermal stability than the unfilled electrolyte. In addition, the introduction of filler particles into the polymeric membrane resulted in an increment of the ionic conductivity from 0.021 to 1.02 mS•cm −1 at an ambient temperature. Also, it led to a drop in the activation energy from 62.18 to 13.05 kJ•mol −1 . The filler-filled polymer electrolyte revealed a steady platform up to 5.5 V with a high ion transference number of 0.4. In a Li/LCO halfcell, the designed polymer electrolyte showed reversible Li + /Li in the cyclic voltammetry test after five cycles. More importantly, the prepared coin cell exhibited a discharge capacity of 136 mA•h•g −1 at 0.5 C after 100 cycles and retained 96% of the initial discharge capacity. The results of this investigation suggested that a polymer electrolyte filled with the synthesized NiNP@RF@Fe 3 O 4 additive could be a promising candidate toward engineering high-efficient solid lithium-ion batteries.

“…While the ionic conductivity and the mechanical stability were improved after the addition of 10 wt% LLZTO, the thermal decomposition of the PVDF/LLZTO composite electrolyte decreased to 310°C (Figure 3J). Solid polymer electrolytes (e.g., poly(ethylene oxide)) possess high crystallinity and low ionic conductivity under room temperature, which are often operated at elevated temperature to ensure improved lithium‐ion mobility 52 . DSC is frequently employed to analyze the thermal‐dependent conductivity for composite solid electrolytes (e.g., polymer electrolytes with functional fillers) by measuring the melting point 53 .…”

Solid‐state lithium batteries (SSLBs) have been broadly accepted as a promising candidate for the next generation lithium‐ion batteries (LIBs) with high energy density, long duration, and high safety. The intrinsic non‐flammable nature and electrochemical/thermal/mechanical stability of solid electrolytes are expected to fundamentally solve the safety problems of conventional LIBs. However, thermal degradation and thermal runaway could also happen in SSLBs. For example, the large interfacial resistance between solid electrolytes and electrodes could aggravate the joule heat generation; the anisotropic thermal diffusion could trigger the uneven temperature distribution and formation of hotspots further leading to lithium dendrite growth. Considerable research efforts have been devoted to exploring solid electrolytes with outstanding performance and harmonizing interfacial incompatibility in the past decades. There have been fewer comprehensive reports investigating the thermal reaction process, thermal degradation, and thermal runaway of SSLBs. This review seeks to highlight advanced thermal‐related analysis techniques for SSLBs, by focusing particularly on multiscale and multidimensional thermal‐related characterization, thermal monitoring techniques such as sensors, thermal experimental techniques imitating the abuse operating condition, and thermal‐related advanced simulations. Insightful perspectives are proposed to bridge fundamental studies to technological relevance for better understanding and performance optimization of SSLBs.

“…16 Therefore, the PEObased all-solid-state Li-ion batteries (ASSLIBs) need to operate at elevated temperatures for sufficient Li-ion conductivity; however, this might lead to the thermal safety issues and lithium dendrite growth. 17,18 Thus far, various approaches have been reported to enhance the Li-ion conductivity, mechanical strength, and thermal/ electrochemical stability of the PEO-based SPEs. 19−22 Introduction of a three-dimensional (3D) skeleton is the most common way to improve the mechanical strength of the PEO-based SPEs, and the common skeletons include glass fabric, polyimide/polyamide porous films, and common separators.…”

Due to the rapidly increasing demands of lithium-ion batteries, it is imperative to develop separators and even solid-state electrolytes with high biocompatibility/biodegradability to increase their sustainable economic values. In this context, we develop a series of 2,2,6,6-tetramethylpiperidine-1-oxyl-oxidized cellulose nanofiber (TOCN)-embedded solid polymer electrolytes (SPEs) through an environmentally friendly one-pot, organic solvent-free manufacturing process, for which the natural TOCN acts as a rigid 3D skeleton and polyethylene glycol (PEG3350) acts as the soft matrix. Unlike typical inorganic fillers (e.g., Al2O3), the addition of a small amount of TOCN into PEG allows the formation of free-standing SPE films. In addition to greatly improving the mechanical strength, the introduced TOCN preserves sufficient ion transport channels. The optimized free-standing TP28 SPE membrane possesses a decent ionic conductivity of 4.89 × 10–4 S cm–1 associated with a t Li+ value of 0.31 at 80 °C, a high electrochemical stability window of >4.0 V, and a high tensile strength of 1.10 MPa. It also exhibits effective functionality and compatibility with the Li-metal (Li-symmetric cell cycling over 900 h at 80 °C) anode and the LiFePO4 cathode. The assembled all-solid-state LiFePO4|TP28|Li battery delivers great rate capability and cycling performance (96.5% after 100 cycles) with an initial capacity of 151 mAh g–1 at 0.1 C at 60 °C. Our results demonstrate the promising potential of lignocellulosic biomass for fabricating biocompatible SPEs for Li-metal batteries that can largely increase their sustainable economic values.
