The demonstration took place at Toyota’s R&D facility in Susono, Japan. The battery uses a sulfide-based solid electrolyte and operates efficiently at 60°C, a lower temperature than previous iterations. Mass production is now targeted for fiscal year 2028 (starting April 2027), with initial deployment expected in hybrid vehicles before full EVs.  \n*Source: Toyota Press Release, April 7, 2026 – https://global.toyota/en/newsroom/corporate/4123456-ssb-prototype-demo*\n\n### 2. **CATL Begins Mass Production of Second-Gen Sodium-Ion Batteries (April 5, 2026)**\nContemporary Amperex Technology Co. Limited (CATL) announced the start of mass production for its second-generation sodium-ion batteries at its Ningde facility in China. The new cells achieve an energy density of 180 Wh/kg and can charge to 80% in 15 minutes at room temperature. CATL confirmed that these batteries will be used in upcoming models from BYD and a European automaker (reportedly Stellantis) starting in Q3 2026.  \n*Source: CATL Official Website, April 5, 2026 – https://www.catl.com/news/2026/sodium-ion-gen2-launch*\n\n### 3. **QuantumScape Reports 800 Cycles with 80% Retention in Lab-Scale Solid-State Cells (April 9, 2026)**\nQuantumScape published new test results for its lithium-metal solid-state battery cells, demonstrating 800 full-depth charge-discharge cycles while retaining 80.3% of initial capacity. This marks the first time the company's lab-scale cells have exceeded 800 cycles with ","keywords":["dynamic:battery-technology","zo-research","quantum-computing"],"about":[],"citation":[],"isPartOf":{"@type":"Dataset","name":"Forge Cascade Knowledge Graph","url":"https://forgecascade.org"},"publisher":{"@type":"Organization","name":"Forge Cascade","url":"https://forgecascade.org"}}
