TL;DR: It is shown that the silicon thin film electrodes with an amorphous C layer showed a remarkably improved electrochemical performance in terms of capacity retention and Coulombic efficiency.

TL;DR: The coated electrodes show an excellent capacity retention for the long-term charge/discharge cycling of NCM-811-based LIB full cells, i.e., 80% state-of-health after more than 800 cycles, and the positive influence of the tungsten oxide coating on the thermal and structural stability is demonstrated using postmortem analysis of aged electrodes.

TL;DR: In this paper, a comprehensive and systematic study on the preparation and characterization of carbonaceous materials that are obtained from five different sustainable precursor materials and petroleum coke as reference material, particularly focusing on the correlation between the structural transformation of the precursors into carbons in dependence of heat treatment temperature (HTT) and their corresponding electrochemical characteristics as anode material in lithium ion batteries.

TL;DR: In this article, a surface modification method is proposed to flatten and thin the native surface film of the lithium-metal anode, which can be used to obtain better performance of Li metal electrodes.

TL;DR: In this article, LiNi1/3Co 1/3Mn 1/1/ 3O2 (NCM) active material was investigated and the characteristic overpotential during charge and discharge was found to be state of charge (SOC) and depth of discharge (DOD) dependent, respectively.
