Summary: A novel clay/cross-linked network polymer-based artificial SEI layer (NCL) is developed to prevent the formation of lithium dendrites, leading to enhanced cyclability and excellent mechanical performance in lithium metal batteries. The NCL-protected LM symmetrical cells exhibit stable cycling performance for over 1000 hours, while the NCL-Li vertical bar Cu half-cells demonstrate dendrite-free and reversible Li deposition with a high Coulombic efficiency of 99% for 170 cycles. The LiFePO4 full-cell and LiNi0.8Co0.1Mn0.1O2-coupled pouch-cells also achieve outstanding capacity retention over multiple cycles and show reliable performance under different damage conditions, highlighting the potential of NCL for practical application in high-performance LMBs.

Summary: A multi-site substituted strategy is employed to enhance the stability of O-3-type NaNi0.5Mn0.5O2. Simulations indicate that the Ti substitution decreases the charge density of Ni ions and improves the antioxidative capability of the material. In situ characterizations verify that the complicated phase transformation is mitigated during the charge/discharge process, resulting in greatly improved structure stability. The co-substituted cathode delivers a high-rate capacity of 97 mAh g(-1) at 5 C and excellent capacity retention of 81% after 400 cycles at 0.5 C.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
