Ni-rich materials are appealing to replace LiCoO2 as cathodes in Li-ion batteries due their low cost and high capacity. However, there also some disadvantages for cathode such poor cycling rate performance, especially under voltage. Here, we demonstrate the effect of dual-conductive layers composed Li3PO4 PPy layered material. Fourier transform infrared spectroscopy X-ray photoelectron show that coating PPy. (NH4)2HPO4 transformed after reacting with surface lithium residuals formed an...
Li excess LiNi0.8Co0.1Mn0.1O2 was produced by sintering the Ni0.8Co0.1Mn0.1(OH)2 precursor with different amounts of a lithium source. X-ray photoelectron spectroscopy confirmed that greater Li+ leads to an increase in number Ni2+ ions. Interestingly, level Li+/Ni2+ disordering decreases content determined I003/I104 ratio diffraction patterns. The electrochemical measurement shows cycling stability and rate capability improve content. After cycling, impedance decreased charge transfer...

High-capacity silicon has been regarded as one of the most promising anodes for high-energy lithium-ion batteries. However, it suffers from severe volume expansion, particle pulverization, and repeated solid electrolyte interphase (SEI) growth, which leads to rapid electrochemical failure, while size also plays key role here its effects remain elusive. In this paper, through multiple-physical, chemical, synchrotron-based characterizations, evolutions composition, structure, morphology,...
Tremendous studies have been engaged in exploring the application of solid-state electrolytes (SSEs) as it provides opportunities for next-generation batteries with excellent safety and high energy density. Among existing SSEs, newly developed halide SSEs become a hot spot owing to their ionic conductivity up 1 mS cm −1 stability against high-voltage cathode. As result, shown be promising candidates all-solid-state lithium (ASSLBs). Here, we review progress available modification strategies...
