A solid-state electrolyte (SSE) is a solid ionic conductor and electron insulator that is a key component of a solid-state battery. It is valuable for applications in electrical energy storage (EES), particularly in the replacement of liquid electrolytes present in lithium-ion batteries.
Solid-state batteries use a technique similar to lithium-ion batteries to extract power from the batteries. Ions flowing through the electrolyte between the cathode and anode create electrical flow.A solid-state battery offers a better energy density than a liquid electrolyte solution-based Li-ion battery.
Because there is no danger of explosion or fire, there is no need for safety components, which saves space. Solid state batteries use lithium-oxygen and nitrogen-based polymer thin film electrolytes exclusively. Ag-doped germanium chalcogenide thin film solid state electrolyte systems are examples of non-Li based thin film solid state batteries.
The Global Solid State Battery Electrolyte Membrane market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
High-performance free-standing hybrid solid electrolyte membrane. Hybrid solid electrolytes (HSEs) have gained a lot of interest for all-solid-state lithium-based batteries (ASSBs) because of their high ionic conductivity, high mechanical strength, increased electrochemical stability, and good lithium dendrite suppression capabilities.
Free-standing HSE membranes were created utilising a poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) matrix and hexagonal-BN (h-BN) composite ceramic fillers with varying quantities of h-BN. The ideal concentration of h-BN (10 wt%) in the HSE membrane lowers the crystallinity of the PVDF-HFP matrix, increases the fraction of the electroactive phase, and improves the mechanical strength of the HSE membrane.
The PVDF-HFP/LALZO/h-BN 10% HSE membrane further showed enhanced electrochemical characteristics, such as a lithium-ion transference number, ionic conductivity, electrochemical stability window, and efficient lithium dendrite suppression ability.
With an average capacity, coulombic efficiency, and capacity retention of 92% after 100 cycles, the ASSB, which included a LiFePO4 cathode, PVDF-HFP/LALZO/h-BN 10% HSE, and Li metal anode, increased battery performance.
