[Solid-State: GEM Co-Founds Joint Laboratory For Solid-State Battery Cathode Materials]

On June 5, 2026, Helios Horizon achieved the world’s first crewed fixed-wing flight powered by solid-state batteries. The test validated solid-state technology in real aviation conditions, showing a 60% energy density improvement (410 Wh/kg) and 15‑minute fast charging. While cost and certification remain challenges, the milestone recalibrates industry expectations and offers a clearer path forward for electric aviation.

【Phosphorus Chemicals: Wengfu Raises Wet-Process 85% Phosphoric Acid Price by RMB 500 to RMB 12,100/ton】 On June 15, 2026, according to SMM, Wengfu increased its ex-factory price for wet-process 85% phosphoric acid by RMB 500 to RMB 12,100/ton. Driven by sharp fluctuations in sulfur prices, this hike is intended to ease tight supply pressures and curb downstream demand. A total of 800,000 tonnes of capacity at the Dazhou and Shanghang bases remain offline. Outlook: Significant geopolitical influences are expected to keep prices volatile in the short term. The rise in phosphoric acid prices further pushes up production costs for iron phosphate and lithium iron phosphate (LFP).

Dongfeng’s new-generation solid-state battery (oxide-polymer composite) to start mass production in 2H 2026; demo vehicles logged >3.2 million km safely. Dongchi Energy’s semi-solid device shipped to Djibouti (offshore oil platform application). Aviation solid-state battery energy density exceeds 480Wh/kg, boosting eVTOL range by 65%+. Sun Xueliang’s team achieved low-cost Li₂S (cutting sulfide electrolyte cost by >86%) and Li-Te battery with 13,000+ cycles.
