The use of gel polymer electrolytes (GPEs) is great interest to build high-performing rechargeable lithium metal batteries (LMBs) owing the combination good electrochemical properties and improved safety. Herein, we report a facile scalable one-pot preparation method GPE based on highly safe polyethylene glycol dimethyl ether (PEGDME) plasticizer in poly(vinylidenefluoride-co-hexafluoropropylene) (PVDF-HFP) matrix. prepared exhibits excellent safety (nonflammability thermal stability up 250...
Multinary lithium oxides with the rock salt structure are of technological importance as cathode materials in rechargeable ion batteries. Current state-of-the-art cathodes such LiNi1/3Mn1/3Co1/3O2 rely on redox cycling earth-abundant transition-metal cations to provide charge capacity.

Ni, Fe-based nitrides have been widely studied in the last years due to their interesting properties such as high electrical conductivity and versatile physical chemical properties. In particular, they were for hydrogen evolution reaction (HER) oxygen (OER) alkaline media, displaying electrocatalytic activities similar Pt other conventional noble metal electrocatalysts.

Layered LiMO 2 compounds can be considered as a progressive substitution of excess Li + for M 3+ in the [MO ] layers, with 1:1 Li:M ratio. A derivative from this type compound corresponds to material general formula Li(Li 1/3 2/3 )O . This has been alternatively described MO 3 (where reported Mn, Ru, Ti, Zr, Sn, Pt), and often referred “Li-rich” rocksalt oxide (with Li/M > 1 space group C2/m ).
