“…90,94 The principle mechanism for the enhanced ionic conductivity has been known as the local formation of the amorphous phase of the polymer around each filler particle, which provides a preferential Li ion pathway. 99,104 However, the role of the filler in promoting the Li ion transport still remains to be addressed clearly. As mentioned, the polymer electrolyte with filler added also provided better Li/electrolyte interfacial compatibility, which strongly depended on the particle size 8 and/or the nature 105 of the filler.…”

Li-air(O2) and Li-S batteries have gained much attention recently and most relevant research has aimed to improve the electrochemical performance of air(O2) or sulfur cathode materials. However, many technical problems associated with the Li metal anode have yet to be overcome. This review mainly focuses on the electrochemical behaviors and technical issues related to metallic Li anode materials as well as other metallic anode materials such as alkali (Na) and alkaline earth (Mg) metals, including Zn and Al when these metal anodes were employed for various types of secondary batteries.

“…This is probably due to the increase of the resistive interfacial areas and the decrease of the effective conducting volume. 54 Li ion transference number (t Li+ ) testing shows a value of ∼0.21 for all the three ceramic/polymer composite electrolyte, compared to 0.17 for PE50. This can be explained by the preferential adsorption of anions on the surfaces of the ceramic particles, 55,56 which is the case in our related work for LICGC TM particles.…”

“…This can be ascribed to the interaction between the modified polymerceramic interface as reported before. 34,[52][53][54] Further increase of the ceramic loading to 30 wt% resulted in the decrease of the ionic conductivity. This is probably due to the increase of the resistive interfacial areas and the decrease of the effective conducting volume.…”

The development of a safe electrolyte is the key to improving energy density for next generation lithium batteries. In this work, UV-crosslinked poly(ethylene oxide) (PEO) -based polymer and composite electrolytes are systematically investigated on their ionic conductivity, mechanical and electrochemical properties. The polymer electrolytes are plasticized with non-flammable linear short-chain PEO. In the composite electrolytes, a doped lithium aluminum titanium phosphate (LATP) ceramic, LICGC™, is used as the ceramic filler. It is found that the addition of the plasticizer leads to a tradeoff between ion transport and mechanical properties. In contrast, the addition of ceramic fillers improves both the ionic conductivity and mechanical properties. The sample with 20 wt% of LICGC™ shows a conductivity of ∼0.6 mS cm−1 at 50 °C. This sample also demonstrates much longer cycle life than the neat polymer electrolyte in Li platting/stripping test with a capacity of 1 mAh cm−2. A full cell made with this composite electrolyte against Li metal anode and high voltage LiNi0.6Mn0.2Co0.2O2 cathode shows 94% capacity retention after 30 cycles, compared to 58% capacity retention with the neat polymer electrolyte. These results demonstrate that a hybrid of polymer/ceramic/non-flammable plasticizer is a promising path to high energy density, high voltage lithium batteries.
