Summary: Coating Zr-based metallic glass on Cu current collector and Li metal anode improves the cycle performance of anode-free Li-ion batteries and Li metal batteries. The isotropy and homogeneity of Zr-MG enhance the surface uniformity of the current collector and metal anode. Thin film coatings of Zr-MG on CC and LMA reduce overpotential and result in more uniform Li plating morphology in AFLBs, while leading to stable capacity in LMB.

Summary: This study discovers a competitive bi-anion activity in electrolytes with the co-existence of two anions, which allows for controlled Li-salt decomposition kinetics and entirely favorable interphasial chemistry on both Li-metal anode and ultrahigh-nickel cathode. The proposed bi-anion localized high-concentration electrolytes demonstrate superior electrochemical compatibility toward Li metal and long-term cycling stabilities under both 4.4 and 4.6 V in Li-metal batteries with ultrahigh-nickel cathode.

Summary: This paper introduces a novel fast charging procedure that reduces the deposition of metallic lithium on the surface of the negative electrode by regulating the current through the correlation between electrode polarization and anode potential. The linear relationship between cell voltage and anode potential is shown independently of current rate, temperature, and initial SOC. By implementing anode potential regulation based on this relationship, the risk of unwanted lithium plating is significantly reduced. The advantage of this implementation is that it does not require a P2D model on a micro-controller, making it suitable for embedded systems.

Summary: Lithium (Li) metal is a promising candidate for high-energy batteries. In this study, a controllable dual-layer solid electrolyte interphase (SEI) is constructed to protect the Li metal anode and improve the electrochemical performance. The self-induced dual-layered SEI consists of a predeposited LiAlO2 (LAO) layer, which results in the reduction of electrolyte and the formation of an outer organic layer. The robust inner LAO layer promotes uniform Li deposition while the outer organic layer improves the stability of SEI.

Summary: This study investigates the thermal safety changes and degradation mechanisms of lithium-ion batteries after deep aging under fast charge cycling. Lithium plating is identified as the primary degradation mechanism, which thickens the solid electrolyte interface film, leads to increased impedance and decreased capacity. Aged cells have higher heat generation rates but reduced total heat generation compared to fresh cells. Fast charge cycling reduces the thermal stability of the anode and decreases the triggering temperature for thermal runaway. Additionally, it decreases the lithium plating potential, resulting in advanced side reactions contributing to thermal runaway. The loss of active materials reduces the maximum temperature and maximum temperature rise rate of aged cells.

Summary: Energy level matching and structural stabilization of semiconductor electrode materials are critical for improving the efficiency and durability of bifunctional catalysts for photo-enhanced rechargeable Zn-air batteries. We developed a photoactive bifunctional air-electrocatalyst comprising n-type g-C3N4 and p-type copper-doped ZIF67 (CuZIF-67) composite. It exhibits wide-range solar spectrum absorption and enhanced electron-hole pairs separation efficiency, leading to higher oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) activities compared with single p-and n-type catalysts. It has photo-enhanced charge/discharge abilities and stable cycling performance.

Summary: Alkali-metal adatom-modified amorphous carbon cluster passivation films (CCF-Ms) were formed on Zn-anodes using radiofrequency plasma thermal evaporation and alkali-metal hydroxide treatment. CCF-M enhanced the corrosion resistance, suppressed dendrite growth, and improved Zn2+ transport kinetics on the Zn-anode. After 5000 and 1302 cycles in a symmetric cell, Zn2+ could deposit rapidly and uniformly below CCF-M without dendrites and side reactions.
