Lithium-ion batteries (LIBs) with liquid electrolytes (LEs) have problems such as electrolyte leakage, low safety profiles, and low energy density, which limit their further development. However, LIBs with solid electrolytes are safer with better energy and hightemperature performance. Thus, solid electrolyte system batteries have attracted widespread attention. However, due to the inherent rigidity of the LATP solid electrolyte, there is a high interface impedance at the LATP/electrode. In addition, the Ti element in LATP easily reacts with the Li metal. Here, we dripped an LE at the LATP/electrode interface (solid−liquid hybrid electrolytes) to reduce its interface impedance. A composite polymer electrolyte (CPE) protective film (containing PVDF, SN, and LiTFSI) was then cured in situ at the LATP/Li interface to avoid side reactions of LATP. The discharge specific capacity of the LiFePO 4 /LATP-12% LE-CPE/Li system is up to 150 mAh g −1 , and the capacity retention rate is still 96% after 250 cycles. In addition, the NCM622/PVDF-LATP-12% LE/Li system has an initial reversible capacity of 170 mAh g −1 . This study reports an approach that can protect solid electrolytes from lithium metal instability.

“…Generally, doping salt is widely used and plays a vital role in the conduction of electrolytes. Numerous salts have been reported in the electrolytes for various electrochemical devices such as magnesium trifluoromethanesulfonate (MgTf 2 ) , lithium triflate (LiTF), lithium bis(oxalato)borate (LiBOB), lithium phosphate (LiPO 4 ), etc. ,− In DSSCs performance, the redox mediator is a vital electrolyte component that functions to regenerate dye and ionic transport between the working electrode and counter electrode. , Commonly in DSSC, iodide/tri-iodide (I – /I 3 – ) redox pair is the most favorite choice for efficient performance . These redox pairs have produced efficiency up to 12.6% under the sun illumination achieved by the EPFL group. , Besides, incorporating iodide salt into the electrolytes could affect their ionic conductivity as well as the J SC of DSSC.…”

Review on the Revolution of Polymer Electrolytes for Dye-Sensitized Solar Cells

Dye-sensitized solar cells (DSSCs) are a suitable replacement for conventional silicon solar cells due to their unique features, such as high energy conversion efficiency and cheap manufacturing cost. The liquid-state DSSCs, however, are poorly sustainable on a long-term basis because volatile liquids are used. The early intention of incorporating polymer into the liquid electrolytes was to curb the problem encountered by liquid electrolytes and enable the DSSCs to function as a long-term stability device. This work briefly reviews how the improvisation has been done on the polymer electrolytes formulation and the extent of how each element can affect the cell efficiency and long-term stability. The role of each component, such as the type of host polymer, iodide salts, nanoparticles, and organic additives that improve the performance of DSSCs, has also been highlighted. This clarified the main purpose of introducing various types of additives into electrolytes to enhance the transport properties as well as the performance of the DSSCs.
