Solid-State Battery Breakthrough News — Hype Or Hope? - CleanTechnica
Scientists at the Chinese Academy of Sciences have developed a novel self-healing interface for solid-state lithium batteries that mimics a liquid seal by flowing to fill microscopic gaps between the anode and solid electrolyte. This innovation eliminates the need for heavy external pressure and bulky equipment traditionally required to maintain tight contact within the battery. The key mechanism involves the controlled migration of iodide ions under an electric field, which form an iodine-rich layer attracting lithium ions to fill pores at the interface, thereby enhancing stability and performance. This approach simplifies manufacturing, reduces material use without increasing costs, and enables batteries to achieve specific energies exceeding 500 watt-hours per kilogram—potentially doubling device battery life. While the prototype has shown promising stability and exceptional performance over hundreds of charge/discharge cycles in laboratory tests, the technology remains at an early stage, with significant challenges ahead before commercial viability. Real-world testing under varying temperatures, fast charging, and long-term use is necessary to confirm safety and durability, especially given past costly failures like the

Researchers at Japan’s Tohoku University have demonstrated that two pressure-assisted sintering methods—hot pressing (HP) and spark plasma sintering (SPS)—are equally effective for fabricating dense, high-quality garnet-type oxide solid electrolytes (Li₇La₃Zr₂O₁₂ or LLZO) for next-generation solid-state lithium metal batteries (SSLMBs). Both techniques achieve nearly full densification (~98%) in under five minutes without significant differences in ionic conductivity or microstructure. This challenges the previously held belief that SPS offers unique advantages due to a “plasma effect,” showing instead that densification is driven primarily by applied pressure and heat. The study, published in Small, highlights that either HP or SPS can be chosen based on factors such as cost, equipment availability, and scalability rather than presumed performance superiority. This finding is significant because conventional oxide electrolyte fabrication requires prolonged high-temperature sintering, which is costly and leads to lithium evaporation. By validating these rapid

Researchers have developed solid-state sodium batteries that maintain performance even at subzero temperatures, marking a significant advancement toward making sodium a viable alternative to lithium in battery technology. Sodium is abundant, inexpensive, and environmentally less damaging than lithium, but prior solid-state sodium batteries struggled with ionic conductivity and performance at room temperature. The team combined computational and experimental methods to stabilize a metastable form of sodium hydridoborate by heating it to its crystallization point and then rapidly cooling it, a technique not previously applied to solid electrolytes. This process kinetically locks the orthorhombic phase, which exhibits fast sodium-ion mobility and significantly higher ionic conductivity—up to an order of magnitude greater than previously reported structures. By pairing this stabilized sodium hydridoborate phase with a chloride-based solid-electrolyte-coated cathode, the researchers created thick, high-areal-loading composite cathodes that retain performance down to subzero temperatures. This design contrasts with earlier strategies that used thin cathodes,

Solid-state batteries hold significant promise for electric vehicles (EVs) by offering higher energy density, faster charging, and improved safety compared to traditional lithium-ion batteries. Lithium-ion technology, which currently powers most EVs and consumer electronics, is nearing its energy density limits—around 260 Wh/kg—necessitating heavier battery packs for longer ranges and requiring cooling systems to prevent thermal runaway. In contrast, solid-state batteries replace the liquid electrolyte with solid materials such as ceramics or polymers, enabling denser electrodes and potentially exceeding 400 Wh/kg energy density with lithium metal anodes. However, this architecture introduces challenges like high interfacial resistance, mechanical stress during cycling, and dendrite formation, which can cause short circuits. Unlike liquid electrolytes that self-heal electrode gaps, solid electrolytes require precise manufacturing techniques to maintain stable interfaces. The main barrier to widespread adoption of solid-state batteries is scaling up manufacturing to automotive levels. Researchers Mihri Ozkan and Cengiz Ozkan from the University of California

Researchers at the University of Chicago Pritzker School of Molecular Engineering have developed a new sodium-based solid-state battery technology that performs effectively at room temperature and below freezing, marking a significant advance for sodium batteries which have historically struggled under real-world conditions. The breakthrough centers on stabilizing a previously unreported metastable structure of sodium hydridoborate, achieved by heating and rapidly cooling the material to lock in a crystal form. This structure exhibits ionic conductivity at least an order of magnitude higher than previously reported sodium electrolytes, enabling better battery performance. The team combined this metastable electrolyte with an O3-type cathode coated with a chloride-based solid electrolyte, allowing for thick, high-loading cathodes that increase the theoretical energy density by packing more active material into the battery. This design contrasts with traditional thin cathodes that contain more inactive material, thus improving energy storage capacity. The innovation not only enhances sodium battery performance but also offers a more cost-effective and sustainable alternative to lithium-based batteries, potentially enabling gig

Researchers at the Korea Research Institute of Chemical Technology (KRICT) have developed a novel molybdenum disulfide (MoS2) thin film coating that significantly enhances the lifespan and stability of anode-free all-solid-state batteries (AFASSBs). By applying MoS2 nanosheets onto stainless steel current collectors via metal-organic chemical vapor deposition (MOCVD), the team created a cost-effective, scalable alternative to expensive noble metal coatings. This MoS2 layer acts as a sacrificial buffer that reacts with lithium during battery cycling, forming a stable interfacial layer of molybdenum metal and lithium sulfide (Li2S). This dynamic interface improves lithium affinity, prevents dendrite formation, and boosts capacity retention by seven times, enabling stable operation for over 300 hours and tripling battery runtime. The innovation addresses key challenges in AFASSBs, which eliminate the anode to reduce cell volume and increase energy density but suffer from interfacial instability and dendrite growth
