Hao, Xiaojing published the artcileA gel polymer electrolyte based on PVDF-HFP modified double polymer matrices via ultraviolet polymerization for lithium-sulfur batteries, Recommanded Product: Pentaerythritol tetra(3-mercaptopropionate), the main research area is PVDF HFP UV polymerization lithium sulfur battery; Gel polymer electrolyte; Lithium-sulfur battery; Quasi-solid-state; Ultraviolet polymerization.
Currently, as a new kind of separator, gel polymer electrolytes (GPEs) not only should play a role to sep. cathode and anode, but also should have high ionic conductivity to guarantee the elevated electrochem. performances. As for quasi-solid-state lithium-sulfur batteries (LSBs), it is also very important to confine the shuttle effect and Li dendrite growth. Herein, we synthesize GPEs polymerized under UV, in which the poly(vinylidene fluoride-hexafluoro propylene) (PVDF-HFP) is one of the polymer matrixes to provide high ionic conductivity and toughness, pentaerythritol tetrakis-divinyl adipate (PETT-DA) is another polymer matrix to simultaneously suppress shuttle effect and lithium dendrite. More importantly, Li6.4La3Zr1.4Ta0.6O12 (LLZTO) provides the Li+ transport sites to facilitate the Li+ transport speed. Meanwhile, it can hinder the crystallization of polymers, reducing crystallinity of GPEs. Prominently, the designed GPEs with 10 wt% LLZTO have elevated ionic conductivity of 8.74 × 10-4 S cm-1 and Li+ transference number of 0.69, accompanied with superb capacity retention of 88.6% after 300 cycles at 1C. Importantly, the excellent mech. properties and thermal stability give more potentials to the commercialization of LSBs.
