Summary: The addition of KPF6 in the electrolyte can promote the formation of a robust SEI layer, effectively inhibiting the growth of Li dendrites. The KPF6 additive can form a thin and durable SEI layer rich in LiF, which blocks the electron leakage pathways. Additionally, KPF6 additive can reside at defect sites, hindering the incoming of Li+ and restricting the growth of Li dendrites. Optimizing the electrode/electrolyte interphase by controlling the concentration of additives has implications for fast charging.

Summary: A cost-effective electrolyte additive, potassium trifluoroacetate, is proposed to fabricate a stable solid electrolyte interphase for dendrites-free lithium deposition. TFA- anions can interact with Li+ and form a solid electrolyte interphase with abundant inorganic species. Molecular dynamic simulations show that TFSI- and NO3- anions in the electrolyte can replace solvent molecules and participate in the Li+ solvation sheath. This is attributed to the strong polar interaction between TFA- anions and Li+, which weakens the coordination of solvent molecules. With the assistance of electrostatic shielding of K+, the Li deposition morphology is significantly improved.

Summary: To address the issue of lithium (Li) plating on graphite anodes during fast charging, Li plating regulation and morphology control are proposed. A Li plating-reversible graphite anode is achieved through a localized high-concentration electrolyte (LHCE), resulting in high reversibility and stability. The stable LiF-rich solid electrolyte interphase (SEI) enables a higher average Coulombic efficiency (99.9%) and reversibility of Li plating (99.95%). A self-made LiNi0.5Mn0.3Co0.2O2 | graphite pouch cell exhibits a competitive capacity retention of 84.4% even at high current (7.2 A) after 150 cycles, demonstrating the potential for high-performance fast-charging batteries.

Summary: Formaldehyde exposure during pregnancy can cause fetal congenital heart disease (CHD). High-throughput sequencing was used to identify the expression profiles of long non-coding RNAs (lncRNAs) in heart tissues of normal and formaldehyde-exposed newborn rats. A total of 763 differentially expressed lncRNAs were identified, and the Ras and hedgehog signaling pathways were identified as important regulatory pathways in CHD caused by formaldehyde exposure. Several upregulated lncRNAs were validated and may provide a reference for diagnosing and treating CHD.

Summary: The stability of Li||LiNi0.8Co0.1Mn0.1O2 (NCM811) batteries under high voltage was improved by adding pentafluorostyrene (PFBE) to the electrolyte. PFBE facilitated the formation of LiF/Li2CO3-rich interphases on the cathode and anode surfaces, which effectively mitigated irreversible phase transition, stress-induced microcracks, and transition metal dissolution. It also controlled the growth of Li dendrites on the anode surface. The 4.5 V Li||NCM811 batteries showed a capacity retention rate of 61.27% after 600 cycles at 0.5 C, and the -6.69 Ah Li||NCM811 pouch cells with the electrolyte achieved a stable energy density of -485 Wh kg-1.

However, issues such as zinc dendrites growth, corrosion, by-product formation, hydrogen evolution, and leakage affect their commercialization. Gel polymer electrolytes (GPEs) can solve these problems and provide a new approach for the application of zinc batteries.

Summary: In order to achieve high energy density and fast reaction kinetics for lithium-sulfur batteries (LSBs), a heterostructure composed of nitrogen-deficient graphitic carbon nitride (ND-g-C3N4) and MgNCN was fabricated using magnesiothermic denitriding technology. The nitrogen-deficient C3N4 acts as a conductive framework, together with MgNCN, effectively capturing lithium-polysulfides (LiPSs) and regulating Li2S nucleation. The oxidation conversion kinetics is also accelerated. The LSBs with catalytic MgNCN/ND-g-C3N4 as the interlayer exhibit remarkable electrochemical performance, with a discharge capacity of 650 mAh g(-1) at 4 C. Outstanding capacity retention can be achieved even with a high sulfur loading.

Summary: In this study, l-carnitine (l-CN) is proposed as an efficient additive to stabilize both electrodes and extend the lifespan of aqueous Zn-ion batteries. The simultaneous presence of quaternary ammonium cations, COO- anions, and hydroxyl groups in a trace amount of added l-CN has a significant impact on the behavior of Zn2+ deposition/insertion and water molecule activity. The addition of l-CN leads to ultralong life in the symmetric cell with an 87-fold improvement in cycle life (over 6000 h, 1 mA cm(-2)/1 mA h cm(-2)) for dendrite-free Zn plating/stripping and enables the Zn//V2O5 full cell to achieve 3500 cycles with a high capacity retention.

Summary: Researchers developed coral-like carbon nanowires doped with nitrogen as a binder-free anode material for potassium-based dual-ion batteries. The unique porous nanostructure and amorphous/short-range-ordered composite feature of the carbon nanowires enhance structural stability, facilitate ion transfer, and improve active site utilization. The anode exhibits diffusive behavior and capacitive adsorption, delivering a high capacity of 276 mAh g-1 at 50 mA g-1, good rate capability up to 2 A g-1, and long-term cycling stability with 93% capacity retention after 2000 cycles at 1 A g-1. Assembling this anode with an environmentally benign cathode yields a potassium-based dual-ion battery with high specific capacity, excellent rate capability, and long-term cycling stability.

Summary: Researchers developed a one-pot solvothermal method to construct an amorphous/crystalline MoO2 (a/c-MoO2) homojunction for high-efficiency sodium-ion batteries. Theoretical simulations showed that electrons redistributing at the homogeneous interface of a/c-MoO2 facilitated charge carrier adsorption and electron/ion transfer. The a/c-MoO2 homojunction exhibited superior Na adsorbability (-1.61 eV) and low Na diffusion energy barrier (0.519 eV), leading to higher capacity, rate capability, and cycling stability compared to a-MoO2 or c-MoO2. Mechanistic studies using in-situ XRD and ex-situ XPS techniques revealed the 'adsorption-insertion-conversion' mechanism for Na' storage of MoO2. This work provides new opportunities for optimizing electrode materials through crystallographic engineering and enhances understanding of the effects of homojunction structure on electrochemical performance.
