The Mixed Ionic and Electronic conducting (MIEC) properties of this composite

Composite solid electrolytes (n-C4H9)4NBF4–nanodiamonds Solid State Ionics (IF 3.2) Pub Date : 2023-11-28 Yulia Mateyshina, Ivan Stebnitskii, Nikolai Uvarov
Nanocomposites (n-C4H9)4NBF4–nanodiamonds were prepared and investigated for the first time. Nanodiamonds (CND) with a specific surface area of 300 ± 20 m2/g and grain size of 5.4 ± 0.3 nm was taken as heterogeneous additive. According to the results of X-ray diffraction and thermal analysis studies, at high fraction of CND the salt transforms to the amorphous phase which is stabilized on the interfaces

A highly effective and controllable chemical prelithiation of Silicon/Carbon/Graphite composite anodes for lithium-ion batteries Solid State Ionics (IF 3.2) Pub Date : 2023-11-21 Peipei Lai, Chunzheng Liu, Zhuo Sun, Zhejuan Zhang
Chemical prelithiation has become an increasingly popular method for compensating the initial irreversible capacity loss of lithium ion batteries and improving their initial Coulombic efficiency (ICE). For composite anode materials composed of silicon, amorphous carbon and graphite (SCG), pre-embedding Li+ into all three components simultaneously by chemical prelithiation is challenging because of
