Organic electrodes are considered competitive candidates for the next-generation high-performance energy storage devices owing to their advantages of structural flexibility and abundant resources. However, solubility and low electronic conductivity have been major obstacles to the practical application. To address these challenges, the structural design and interfacial regulation of organic electrodes are crucial to the performance enhancement. Herein, we report on a π-conjugated polymer cathode material of poly(3,4,9,10-perylenetetracarboxylic diimide) (PPI) for metal ion batteries, and the performance optimization is achieved by matching suitable conductive carbons and liquid electrolytes. Ultimately, the carbon nanotubes (CNTs) with weight content of 25% and 1 M NaPF₆ in ethylene carbonate/diethyl carbonate electrolyte are introduced to assemble the batteries, and the discharge specific capacity, cycling stability and rate performance are enhanced effectively. The PPI-CNT||Na battery displays high specific capacities of 146.4 and 117 mAh g⁻¹ at current densities of 0.1 C and 5 C, respectively. Furthermore, PPI-CNT||Na battery demonstrates excellent long-term cycling stability of 5000 cycles with low 0.007 mAh g⁻¹ capacity decay per cycle at 1C due to the thin and uniform cathode electrolyte interphase. Moreover, the PPI-CNT||Na battery presents good cycling stability at high temperatures of 60 °C, and retains a capacity of 132.5 mAh g⁻¹ after 300 cycles with a high capacity retention rate of 96.9%. Besides, PPI-CNT displays good electrochemical performance and compatibility in lithium-ion and potassium-ion batteries. This work provides an alternative optimization strategy for organic electrodes applied in long-lifetime metal ion batteries.

Aqueous zinc-metal based batteries (AZMBs) perfectly combine safety, economy and pro-environment, but their performance is arresting limited by the interfacial instability caused by the large desolvation energy barrier of [Zn(H₂O)₆]²⁺ and the massive release of active water at the electrolyte/electrode interface. In this review, we briefly outline the solvation structure of zinc ions and the necessity of desolvation. Subsequently, the variety of strategies to solve these issues, mainly including reorganizing solvation sheath by changing electrolyte environment and accelerating interface desolvation by constructing artificial interfacial layer, are categorically discussed and systematically summarized. Meanwhile, perspectives and suggestions regarding desolvation theories, interfacial evolution, material design and analysis techniques are proposed to design highly stable zinc anodes.

Solid polymer electrolytes (SPEs) have attracted much attention for their safety, ease of packaging, cost-effectiveness, excellent flexibility and stability. Poly-dioxolane (PDOL) is one of the most promising matrix materials of SPEs due to its remarkable compatibility with lithium metal anodes (LMAs) and suitability for in-situ polymerization. However, poor thermal stability, insufficient ionic conductivity and narrow electrochemical stability window (ESW) hinder its further application in lithium metal batteries (LMBs). To ameliorate these problems, we have successfully synthesized a polymerized-ionic-liquid (PIL) monomer named DIMTFSI by modifying DOL with imidazolium cation coupled with TFSI⁻ anion, which simultaneously inherits the lipophilicity of DOL, high ionic conductivity of imidazole, and excellent stability of PILs. Then the tridentate crosslinker trimethylolpropane tris[3-(2-methyl-1-aziridine)propionate] (TTMAP) was introduced to regulate the excessive Li⁺-O coordination and prepare a flame-retardant SPE (DT-SPE) with prominent thermal stability, wide ESW, high ionic conductivity and abundant Li⁺ transference numbers (t_Li₊). As a result, the LiFePO₄|DT-SPE|Li cell exhibits a high initial discharge specific capacity of 149.60 mAh g⁻¹ at 0.2C and 30 °C with a capacity retention rate of 98.68% after 500 cycles. This work provides new insights into the structural design of PIL-based electrolytes for long-cycling LMBs with high safety and stability.

In this work, we have applied molybdenum (Mo) and titanium (Ti) co-doping to solve the degradation of Ni-rich cathodes. The modified cathode, i.e., Li(Ni_0.89Co_0.05Mn_0.05Mo_0.005Ti_0.005)O₂ holds a stable structure with expanded crystal lattice distance which improves Li ion diffusion kinetics. The dopants have suppressed the growth of primary particles, formed a coating on the surface, and promoted the elongated morphology. Moreover, the mechanical strength of these particles has increased, as confirmed by the nanoindentation test, which can help suppress particle cracking. The detrimental H2-H3 phase transition has been postponed by 90 mV allowing the cathode to operate at a higher voltage. A better cycling stability over 100 cycles with 69% capacity retention has been observed. We believe this work points out a way to improve the cycling performance, Coulombic efficiency and capacity retention in Ni-rich cathodes.

Sodium-ion batteries (SIBs) are emerging as a promising alternative for large-scale energy storage, particularly in grid applications. Within the array of potential cathode materials, Fe/Mn-based layered oxides are notable for their advantageous theoretical specific capacity, economic viability, and environmental sustainability. Nevertheless, the practical application of Fe/Mn-based layered oxides is constrained by their suboptimal cycle performance and rate capability during actual charging and discharging. Ion doping is an effective approach for addressing the aforementioned issues. In this context, we have successfully developed a novel K⁺ and Mg²⁺ co-doped P2-Na_0.7Fe_0.5Mn_0.5O₂ cathode to address these challenges. By doping with 0.05 K⁺ and 0.2 Mg²⁺, the cathode demonstrated excellent cycling stability, retaining 95% of its capacity after 50 cycles at 0.2C, whereas the undoped material retained only 59.7%. Even within a wider voltage range, the co-doped cathode retained 88% of its capacity after 100 cycles at 1C. This work integrated Mg²⁺ to activate oxygen redox reactions in Fe/Mn-based layered cathodes, thereby promoting a reversible hybrid redox process involving both anions and cations. Building on the Mg doping, larger K⁺ ions were introduced into the edge-sharing Na⁺ sites, enhancing the material's cyclic stability and expanding the interplanar distance. The significant improvement of Na⁺ diffusion coefficient by K⁺/Mg²⁺ co-doping has been further confirmed via the galvanostatic intermittent titration technique (GITT). The study emphasizes the importance of co-doping with different coordination environments in future material design, aiming to achieve high operating voltage and energy density.

Nickel (Ni)-rich layered oxides have drawn great attention as cathode for lithium batteries due to their high capacity, high working voltage and competitive cost. Unfortunately, the operation of Ni-rich cathodes suffers from the notorious structural degradation and interfacial side reactions with electrolytes and thus incurs premature failure, especially at high charge cut-off voltages (≥4.4 V). For this, various structural and interphase regulation strategies (such as coating modification, element doping, and electrolyte engineering) are developed to enhance the cycling survivability of Ni-rich cathodes. Among them, electrolyte engineering by changing solvation structure and introducing additives has been considered an efficient method for constructing robust cathode-electrolyte interphases (CEI), inhibiting the formation of harmful species (such as HF and H₂O) or restraining the dissolution of transition metal ions. However, there is still an absence of systematic guidelines for selecting and designing competitive electrolyte systems for Ni-rich layered cathodes. In this review, we comprehensively summarize the recent research progress on electrolyte engineering for Ni-rich layered cathodes according to their working mechanisms. Moreover, we propose future perspectives of improving the electrolyte performance, which will provide new insights for designing novel electrolytes toward high-performance Ni-rich layered cathodes.

The repeated volume variation of lithium (Li) metal anode (LMA) upon Li⁺ plating/stripping, the volatile interface between Li and the electrolyte, and the incessant growth of Li dendrites on Li metal surface have severely hindered the practical application of Li in constructing high energy-density Li metal batteries (LMBs). Herein, a novel Li host (3D ZnO/CNTs/Cu) featuring ordered microchannels and lithiophilic ZnO species on the inner walls of the microchannels is introduced, which induces the uniform Li⁺ deposition into the microchannels and finally suppresses the formation of Li dendrites. The stable structure of the fabricated 3D Li host can adapt to volume variations upon Li⁺ plating/stripping, thereby enhancing electrochemical performances. Symmetric cells with the 3D ZnO/CNTs/Cu@Li anode exhibited long cycle stability at areal current densities of 0.5 and 2 mA cm⁻²; Full cells maintained a reversible discharge capacity of 105 mAh g⁻¹ after 400 cycles at 1C with a capacity retention of 70%. Meanwhile, ex-situ SEM observations proved that the 3D ZnO/CNTs/Cu@Li anode can keep the structural integrity during charging/discharging (or plating/stripping). This work suggested that lithiophilic nanochannels in the Li host can significantly improve the electrochemical performance and safety of LMBs.
