Solid polymer electrolytes (SPEs) in lithium-ion batteries (LIBs) are emerging as promising alternative for liquid electrolytes. However, one of the drawbacks of SPEs is incompatibility between lithium metal anode / electrolyte that leads to the low ionic conductivity and lower cycling performance of LIBs. The present study show that …

Achieving synergy between ion-conducting polymers and ceramics in a composite electrolyte has been proven to be difficult as the complicated ceramic/polymer interface presents challenges to understand and control. In this work, we report a strategy to utilize discrete ceramic fillers to form a gel composite
Active ceramic fillers have intrinsic Li-ion conductive properties, and can be used directly as solid electrolytes in lithium batteries. 88 In general, active fillers consist of garnet, 68, 89 NASICON, 90 perovskite, 70 and sulfide-type fillers. 91 In addition to the type of inorganic filler, the content and morphology also affect the ionic ...
The CPEs can be used not only in lithium-ion batteries but also in all battery systems that use lithium metal as an electrode like Li–S, Li–O 2, Li–Se, Li–CO 2 batteries because lithium metal is capable of offering a very high theoretical capacity of 3860 mA h g −1 and electrochemical potential as low as −3.04 V vs SHE, and also ...
The selection of suitable electrolytes is an essential factor in lithium-ion battery technology. A battery is comprised of anode, cathode, electrolyte, separator, and current collector (Al-foil for cathode materials and Cu-foil for anode materials [25,26,27].The anode is a negative electrode that releases electrons to the external circuit and oxidizes …

Activated metal-organic frameworks (a-MIL-100 (Fe)) was used as a filler in the solid composite electrolytes (SCEs) for all-solid-state lithium metal batteries. The interactions of functional groups of unactivated MIL-100 (Fe) and a-MIL-100 (Fe) with TFSI - through Lewis acid-base interaction are studied by DFT calculations.
In early tests of the battery at low charge, the lithium metal grew through the ceramic electrolyte and short-circuited the battery. So the researchers used chemical and mechanical treatments to "provide a pristine surface for lithium to plate evenly, effectively suppressing the formation of dendrites or filaments," according to the release.
