The rapid development of portable electronic devices and the efforts to find alternatives to fossil fuels have triggered the rapid development of battery technology. The conventional lithium-ion batteries have reached a high degree of sophistication. However, improvements related to specific capacity, charge rate, safety and sustainability are still required. Solid state batteries try to answer these demands by replacing the organic electrolyte of the standard battery with a solid (crystalline, but also polymer and hybrid) electrolyte. One of the most promising solid electrolytes is Li3xLa2/3−xTiO3 (LLTO). The material nevertheless presents a set of key challenges that must be resolved before it can be used for commercial applications. This review discusses the synthesis methods, the crystallographic and the ionic conduction properties of LLTO and the main limitations encountered through a number of selected studies on this material.

Solid polymer electrolytes (SPEs) have emerged as a viable alternative to traditional organic liquid-based electrolytes for high energy density and safer lithium batteries. Poly(ethylene oxide) (PEO)-based SPEs are considered one of the mainstream SPE materials with excellent dissociation ability of lithium salts. However, the inferior ionic conductivity at room temperature and poor dimensional stability at high temperature limit their utilization. In this work, a semi-interpenetrating polymer network (semi-IPN) forming a precursor based on an ionic liquid (IL) monomer and linear PEO chains were introduced into an electrospun poly(acrylonitrile) (PAN) fibrous mat with subsequent thermal-initiated cross-linking. 1,4-Diazabicyclo [2.2.2] octane (DABCO) and 4-(chloromethyl) styrene were used to synthesize the styrenic-DABCO-based IL monomer with bis(trifluoromethane sulfonyl)imide (TFSI–) or bis(fluoromethane sulfonyl)imide (FSI–) as the anion, named as SDTFSI and SDFSI, respectively. Together, the FSI– and TFSI– anions demonstrate a synergistic effect in providing ion-conductive LiF and Li3N-rich inorganic SEI layer with enhanced lithium dendrite suppression ability. The twofold reinforcement effect is achieved collectively from the semi-IPN structure and the three-dimensional (3D) PAN network that help to construct highly efficient and uniform ion transport channels with excellent flexibility, further suppressing the lithium dendrite growth. The SPEs were dimensionally stable even at elevated temperatures of 150 °C. Moreover, the SPEs show an ionic conductivity of 4.4 × 10–4 S cm–1 at 25 °C and 1.81 × 10–3 S cm–1 at 55 °C and a lithium-ion transference number of 0.56. The favorable electrochemical performance of the SPEs was verified by operating LiFePO4/Li and NMC/Li cells.

Owing to the high specific energy density in theories, abundance of resources, and adherence to environmental standards, rechargeable lithium–sulfur batteries (LSB) have drawn an increasing amount of interest. However, the weak conductivity of the sulfur and discharge products, the drastic breakdown and migration of the intermediates of lithium polysulfide (LiPSs) leading to shuttle effect, and the enormous volumetric change of sulfur particles upon cycle substantially hinder their practical uses. Due to the considerable capacity diminishing caused by the shuttle impact corrosion of the lithium metal, LSBs are thought to have significant commercial application challenges. Engineering nanomaterials’ surface structures can increase the affinity between the cathode with the LiPSs while also enabling the redox kinetics of the LiPSs, which results in a low level of LiPSs in the electrolyte that can restrict the shuttle effect. Sulfur and carbon materials, when combined, effectively increase the efficiency of active materials, increase the conductive properties of cathode components, and serve as a barrier against polysulfides. In this review, a thorough analysis is provided on low‐dimensional carbon materials as cathode, by which the electrode modification technique for limiting the shuttle effect of polysulfide in LSBs and forecast future research trends on the same.
