MIT reveals chemical embrittlement driving dendrite failures in solid-state batteries

MIT researchers reveal that chemical reactions at high currents weaken solid-state electrolytes, enabling dendrite growth at unexpectedly low stress. Using birefringence microscopy and cryogenic imaging, they show embrittlement—not just mechanical stress—limits solid-state batteries and suggest that safer, higher-energy storage will come from chemically stable, tougher electrolytes rather than simply stronger ones.

Electrochemical corrosion drives dendrite growth at low stresses in solid-state batteries

A Nature study on LLZO-based solid electrolytes shows dendrites propagate at stresses far below the mechanical fracture threshold, with plating-induced stresses present during growth; as current density rises, dendrite velocity increases while the stress required for propagation decreases (up to 75% lower than under purely mechanical loading). Cryogenic STEM reveals electrochemically induced electrolyte decomposition and molar-volume changes, indicating an electrochemical embrittlement mechanism that could be mitigated by controlling the phase transitions accompanying instability.

China Trials High-Density Solid-State EV Batteries, Claiming 1,500 km Per Charge

China’s Changan and GAC are planning 2026 road trials of solid-state batteries in electric cars, with Changan claiming 400 Wh/kg energy density and up to 1,500 km per charge, and GAC aiming to deploy the tech in its Hyptec SUV by year’s end. The move is part of broader work on solid-state chemistries—including sodium-based Naxtra variants—promising higher energy density, safer non-liquid electrolytes, and faster charging (potentially around 12 minutes 0-80%). While solid-state tech eyes quicker adoption, Li-ion batteries are expected to persist during the transition, with researchers reporting even higher densities in some lab-developed chemistries.,

Solid-State EV Batteries: Cost, Heat, and Dendrite Dilemmas

Solid-state batteries swap a liquid electrolyte for a solid one in EV cells, promising safety and higher energy density but face major hurdles before mass production: higher overall lithium demand and costs, risk of dendrite-caused short circuits and thermal runaway (with even non‑lithium options like sodium-ion as alternatives), stringent manufacturing tolerances and interfacial resistance at the cathode–electrolyte–anode interfaces, brittle ceramic separators prone to cracking, and thermal-management challenges since solid electrolytes don’t dissipate heat as easily as liquids.

Solid-state power bank shakes up portable charging with safety-first design

ZDNET reviews BMX SolidSafe 5K, a 5,000 mAh wireless power bank that uses solid-state cells to reduce flammability compared with lithium-ion. It supports up to 15W wireless charging via Qi2, includes a USB-C port with 20W output/15W input, and offers pass-through charging, plus a built-in USB-C–to–USB-C cable in the included lanyard and a clear power display. Priced at $79.99, it’s more expensive than typical packs, but advocates safety and future solid-state adoption—though lithium-ion’s low cost and high energy density mean solid-state isn’t poised to replace it yet. The reviewer even notes a controlled safety test where the pack emitted smoke when punctured, underscoring cautious handling.)

"Nissan Accelerates Next-Gen Solid-State EV Battery Production for 2029 Launch"

Nissan plans to mass produce electric vehicles with advanced next-generation solid-state batteries by early 2029, aiming to catch up with and potentially surpass competitors like Tesla and BYD. The company's unfinished pilot plant is scheduled to begin operating a pilot production line by March 2025, with commercial production of EVs set to start in fiscal year 2028-2029. Nissan officials highlighted the potential for solid-state batteries to be more powerful, cheaper, safer, and faster to charge than current lithium-ion batteries, with plans to offer them in a range of models, including pickup trucks.
