Summary: Lithium-ion batteries (LIBs) are crucial for the electric vehicle (EV) industry, and LiNi1-x-yCoxMnyO2 (NCM) is the dominant cathode material used in EV LIBs. Due to the need for increased driving range, Ni content in NCM is maximized, but the resulting Ni-rich NCM is unstable. Doping with foreign elements has been explored as a strategy to overcome this instability, with over 46 elements considered and their effects on LIB performance investigated in numerous research articles. This comprehensive analysis of various doping elements and their impact on LIB performance provides valuable insights for the LIB industry and academia.

Summary: Currently, there is a lack of analysis methods to quantitatively study the effects of cycling-induced damage on the stress evolution and capacity loss in silicon-based batteries. We propose a comprehensive model to address this issue, which is validated through comparisons with experimental results. Contrary to common belief, we suggest a concept of training batteries by introducing sufficient damage to improve retention performance, and its effectiveness is experimentally confirmed. Optimization of the training method is also discussed.

Summary: Rechargeable aqueous Zn/S batteries with a unique hybrid aqueous electrolyte using ethylene glycol as a co-solvent are developed to address the issues of sulfur side reactions and zinc dendrite growth. The Zn/S battery exhibits an unprecedented capacity of 1435 mAh g(-1) and an excellent energy density of 730 Wh kg(-1) at 0.1 Ag-1, as well as a capacity retention of 70% after 250 cycles even at 3 Ag-1. The discharge mechanism involves sequential reduction of elemental sulfur by Zn, forming ZnS, while the charging process involves oxidation of ZnS and short-chain polysulfides back to elemental sulfur. This electrolyte design strategy and unique multi-step electrochemistry provide a new pathway for tackling both key issues and designing better Zn/S batteries in the future.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
