Summary: A new synthetic method using cobalt metal as the precursor is proposed to in situ form LiCoO2, which shows better cycle performance and faster Li+ diffusion rate compared to the commercial synthesis method. The stable cycling performance is achieved by suppressing the order-disorder phase transition through the Co2+ pillar effect. The improved synthesis yield and compacted density of the new method offer a new strategy for the in situ synthesis of cathode materials for lithium-ion batteries.

Summary: In this study, a simple in situ polymerization method of 1,3-dioxolane electrolytes was used to fabricate integrated solid-state lithium batteries. The key to achieving a high-performance battery with excellent interfacial contact among carbon nanotubes (CNTs), active materials, and electrolytes is the in situ polymerization and formation of solid-state dioxolane electrolytes on interconnected CNTs and active materials. These batteries demonstrated high energy density, amazing charge/discharge rate, and long cycle life, thanks to the low resistance of 4.5 omega (-1) and high lithium-ion diffusion efficiency of 2.5x10(-11) cm(2) s(-1).

Summary: We introduced a garnet-type lithium metal fluoride, Li3Na3M2F12 (M = Al, Sc, In), as solid-state lithium-ion conductors for the first time. The mechanically milled Li3Na3M2F12 compounds crystallized in a cubic garnet-like structure. The ionic conductivities of Li3Na3Al2F12, Li3Na3Sc2F12, and Li3Na3In2F12 are relatively low, but still better than the oxide analogues Li(3)Ln(3)Te(2)O(12) (Ln = Er, Gd, Tb, Nd). Strategies for further improving conductivities of garnet-type Li3Na3M2F12 were also presented.

Summary: This study reports the automatic self-healing capability of silicon nanowires, which are important building blocks for high-performance semiconductor nanodevices. Through in situ transmission electron microscopy tensile tests, a recovery of fracture strength (10.1%) on fractured silicon nanowires is achieved. Atomic-resolution characterizations and atomistic simulations reveal the self-healing mechanism and factors affecting the self-healing efficiency. Spontaneous rebonding, atomic rearrangement, and van der Waals attraction are responsible for the self-healing in silicon nanowires. The findings shed light on the self-healing mechanism of silicon nanowires and provide insights into developing high-lifetime and high-security semiconductor devices.

Summary: Increasing the cutoff charge voltage of LiCoO2 (LCO) poses a challenge in balancing high energy density and long cycling life. By adding 2,3-dimethylmaleic anhydride (DMMA) as an electrolyte additive, a stable and robust CEI film enriched with inorganic species is formed, preventing decomposition of electrolytes and erosion of LCO. Experimental techniques combined with theoretical calculations reveal the functioning mechanism. The addition of DMMA improves LCO's capacity retention after cycles, and the presence of other additives further enhances LCO's high-voltage stability.

Summary: Layered nickel-rich transition metal oxides have advantages of high energy density and reasonable cost, but suffer from volume changes that result in microcracks, fractures, and degradation of thermal stability during charge-discharge cycling. In this study, a codoping strategy of Mg and Ti in Li[Ni0.90Co0.05Mn0.05]O2 (NCM90) was proposed, achieving excellent cyclability (98.9% vs 86.6%) after 100 cycles. The enhanced electrochemical performance and reduced volume changes were confirmed by testing an NCM parallel to graphite full cell. This study provides valuable guidance for the application of high nickel cathodes in lithium-ion batteries with improved cycling and thermal stability.

Summary: Popular fluorination methods can weaken Li+-solvent interaction, facilitating the desolvation process at low temperature. However, highly fluorinated compounds sacrifice salt dissociation and ionic conductivity. In this study, functional fluorinations with different degrees of fluorination are used to balance Li+-solvent interactions and ion movement. The moderately-fluorinated ethyl difluoroacetate (EDFA) exhibits a trade-off between weak affinity and sufficient ionic conductivity, enabling excellent fast-charging capability and low-temperature performance in lithium-ion batteries. The wide electrochemical potential window of EDFA-based electrolyte also allows high reversible capacity retention and discharge capacity under harsh conditions.

The utilization of lithium difluoro(oxalate) borate (LiDFOB) as a functional additive for Li||LiNi0.85Co0.1Mn0.05O2 batteries has been investigated comprehensively. The preferential reduction and oxidation decomposition of LiDFOB leads to the formation of a boron-rich interfacial film on both Li anode and NCM85 cathode, suppressing the consumption of active lithium and mitigating structural degradation of the cathode.

Summary: Solid-state Li batteries have high safety and theoretical energy density, but the interfacial reaction between solid state electrolytes and cathodes affects battery performance. This study explores interfacial reactions and compositions between oxide cathodes and sulfide solid electrolytes, finding that the driving force of the electrochemical reaction dominates the interfacial reaction. Preventing the formation of an electronically conductive interphase is crucial, which can be achieved through optimized combination of cathodes and solid electrolytes, as well as functional coatings. A high-throughput screening scheme identifies 48 optimal coating materials. This work highlights the importance of rational coupling of cathodes and solid electrolytes, and optimizing interfacial coating materials for solid-state batteries.

Summary: Lithium-ion batteries (LIBs) are widely used in portable electronic devices and electric vehicles, but the high cost of lithium has led to the exploration of sodium-ion batteries (NIBs) as a cheaper alternative. NIBs have the advantages of abundant sodium resources and the use of inexpensive materials. However, the development of NIBs faces challenges such as irreversible phase transformations, poor air stability, and complex charge-compensation mechanisms.

Summary: In this study, indium (In) ions were introduced into flexible Cu2ZnSn(S,Se)(4) (CZTSSe) solar cells to modify the back interface and passivate deep level defects in CZTSSe bulk. The results showed that In doping effectively inhibited the formation of secondary phase and V-Sn defects, decreased the barrier height at the back interface, passivated deep level defects in CZTSSe bulk, increased carrier concentration, and significantly reduced the V-OC deficit. Eventually, a flexible CZTSSe solar cell with a power conversion efficiency of 10.01% was achieved. This synergistic strategy of interface modification and bulk defects passivation through In incorporation provides a new approach for fabricating efficient flexible kesterite-based solar cells.

Summary: Direct growth of redox-active noble metals and rational design of multifunctional electrochemical active materials play crucial roles in developing novel electrode materials for energy storage devices. In this regard, silver (Ag) has attracted great attention in the design of efficient electrodes. The construction of multifaceted heterostructure cobalt-iron hydroxide (CFOH) nanowires (NWs)@nickel cobalt manganese hydroxides and/or hydrate (NCMOH) nanosheets (NSs) on the Ag-deposited nickel foam and carbon cloth (i.e., Ag/ NF and Ag/CC) substrates is reported. The as-fabricated Ag@CFOH@NCMOH/NF electrode delivered superior areal capacity value of 2081.9 μA h cm-2 at 5 mA cm-2. Moreover, as-assembled hybrid cell based on NF (HC/NF) device exhibited remarkable areal capacity value of 1.82 mA h cm-2 at 5 mA cm-2 with excellent rate capability of 74.77% even at 70 mA cm-2. Furthermore, HC/NF device achieved maximum energy and power densities of 1.39 mW h cm-2 and 42.35 mW cm-2, respectively. To verify practical applicability, both devices were also tested to serve as a self-charging station for various portable electronic devices.
