Fast-charging push accelerates At the centre of the launch is the “Xingchi Supercharge Battery 2.0,” a lithium-iron phosphate (LFP) pack designed for passenger EVs. The battery supports peak charging rates of 15C, enabling a 5% to 95% state-of-charge (SOC) recharge in 9 minutes, or 5% to 75% in 5.5 minutes. The pack demonstrated at the event consists of 264 prismatic cells, delivering over 98.8 kWh capacity at 844.8 V. Maximum current reaches 1,800 A, while cycle life exceeds 1,500 cycles. Company executives stated that ultra-fast charging usage is not limited during the warranty period. Two additional passenger vehicle batteries were introduced: a long-life version claiming zero degradation in the first year and 10% degradation over 10 years, and a range-balanced battery for hybrid vehicles using large cylindrical cells. The hybrid-focused pack supports charging from 10% to 80% in 10 minutes. Sunwoda said its fast-charging development dates back to 2019, progressing from 4C in 2022 to 6C in 2024, before reaching 15C for LFP and 8C for ternary lithium batteries in its latest iteration. Expanding into commercial and storage segments For commercial vehicles, the company presented a dual-gun charging system with peak charging power of 1.44 MW. In the hybrid segment, Sunwoda introduced battery packs ranging from 3 kWh to 7 kWh using 46 mm cylindrical cells. A 5 kWh example pack delivers 150 kW output and supports over 15 km electric range, while integrating DC-DC and 12V systems within a 414 V architecture. Sodium batteries target cost and durability In energy storage, Sunwoda launched multiple sodium-ion and LFP battery cells. According to Xu Zhongling, president of the company’s Central Research Institute, sodium batteries offer over 20,000 cycles at room temperature and more than 10,000 cycles at high temperatures. He highlighted three key advantages: abundant raw material supply, lower lifecycle cost due to durability, and improved safety characteristics compared to LFP and ternary lithium batteries. However, lower energy density limits their use in high-end EVs, positioning them instead for low-voltage vehicle systems and entry-level models. AI integration strategy The company also introduced its “AI+ battery” strategy, focusing on data-driven R&D, multi-scenario deployment, and ecosystem collaboration. The approach aims to integrate AI across battery development, manufacturing, and lifecycle management. Industry context and prior developments Sunwoda has previously disclosed progress on solid-state batteries, including a 400 Wh/kg prototype targeting 1,200 cycles and up to 1,000 km of range, indicating ongoing parallel development beyond lithium-ion systems. The company has also addressed supply chain issues publicly, including clarifying it was not involved in a Volvo-related battery recall and resolving a 323 million USD dispute with a Geely subsidiary earlier in 2026.

The company’s battery mix remains heavily weighted toward LFP chemistry, with minimal ternary lithium share. Industry direction The latest announcements reflect a broader shift in the battery sector. While energy density and cost have historically dominated development, charging speed, lifecycle durability, and application-specific optimisation are becoming central to competition across passenger vehicles, commercial transport, and energy storage systems.
