Topic Information

Dear Colleagues,

This Topic focuses on recent advances in energy materials, next-generation energy devices, and intelligent battery management systems. With the growing demand for high-performance and sustainable energy storage technologies, innovations in materials science, device engineering, and intelligent system integration have become increasingly important. We welcome original research and review articles that explore novel electrode and electrolyte materials, solid-state batteries, and supercapacitors, as well as accurate estimations of the state of charge (SOC), state of health (SOH), remaining useful life (RUL), state of energy (SOE), and state of power (SOP) using AI-based battery management algorithms. Additional topics include modelling, diagnostics, thermal management, and safety strategies for modern battery systems. This Topic aims to provide a multidisciplinary platform that integrates materials innovation, device development, and intelligent control to enable safer, more efficient, and longer-lasting energy solutions.

Poly(ethylene oxide) (PEO)-based solid electrolytes are promising candidates for solid-state lithium metal batteries because of their flexibility and ease of processing. However, their practical application is limited by insufficient mechanical strength and poor interfacial stability. Conventional single-filler strategies typically improve either ionic conductivity or mechanical robustness, making it challenging to simultaneously optimize both properties. In this work, a dual-ceramic strategy is proposed that integrates inert and active ceramic fillers with complementary roles to construct a polymer electrolyte that is both mechanically robust and ionically conductive. The inert ceramic filler promotes lithium-salt dissociation and Li⁺ transport, whereas the active ceramic filler enhances structural integrity and suppresses lithium dendrite growth, enabling a synergistic balance between ionic transport and cycling stability. As a representative implementation, paraelectric SrTiO₃ and Li⁺-conducting Li_6.4La₃Zr_1.4Ta_0.6O₁₂ (LLZTO) are incorporated into the PEO/LiTFSI matrix to construct a composite solid electrolyte (PLLS). The optimized PLLS electrolyte, containing 8 wt% STO and 5 wt% LLZTO, exhibits a high ionic conductivity of $4.48\times {10}^{-4}\mathrm{S}{\mathrm{cm}}^{-1}$, an increased Li⁺ transference number of 0.20, and a wide electrochemical stability window of 5.165 V versus Li/Li⁺ at 60 °C. Li/Li symmetric cells demonstrate stable lithium plating/stripping for nearly 2000 h at a current density of$0.2\mathrm{mA}{\mathrm{cm}}^{-2}$. Furthermore, LiFePO₄/Li full cells retain 92.1% of their initial capacity after 500 cycles at 1 C, and stable cycling performance is also achieved with high-voltage LiCoO₂ cathodes. These results demonstrate that the proposed dual-ceramic synergistic strategy offers an effective and potentially generalizable approach to enhancing the durability of PEO-based solid electrolytes for long-life solid-state lithium metal batteries.

Multiband solar cells offer a promising route to surpass the Shockley-Queisser limit by harnessing sub-bandgap photons through three active energy band transitions. However, realizing their full potential requires overcoming key challenges in material design and device architecture. Here, we propose a novel multiband stacked anti-parallel junction solar cell structure based on highly mismatched alloys (HMAs), in particular dilute GaAsN with ~1–4% N. An anti-parallel junction consists of two semiconductor junctions connected with opposite polarity, enabling bidirectional current control. The structures of the proposed devices are based on dilute GaAsN with anti-parallel junctions, which allow the elimination of tunneling junctions—a critical yet complex component in conventional multijunction solar cells. Semiconductors with three active energy bands have demonstrated the unique properties of carrier transport through the stacked anti-parallel junctions via tunnel currents. By leveraging highly mismatched alloys with tailored electronic properties, our design enables bidirectional carrier generation through forward- and reverse-biased diodes in series, significantly enhancing photocurrent extraction. Through detailed SCAPS-1D simulations, we demonstrate that strategically placed blocking layers prevent carrier recombination at contacts while preserving the three regions of photon absorption in a single multiband semiconductor p/n junction. Remarkably, our optimized five-stacked anti-parallel junctions structure achieves a maximum theoretical conversion efficiency of 70% under 100 suns illumination, rivaling the performance of state-of-the-art six-junctions III-V solar cells—but without the fabrication complexity of multijunction solar cells associated with tunnel junctions. This work establishes that highly mismatched alloys are a viable platform for high efficiency solar cells with simplified structures. Full article
