SVOLT Unveils a Groundbreaking Solution for the Energy Storage Industry: Thermal Composite Stacking + Short Blade Battery Pave the Way for the Industry's Scalable Growth

On April 10, 2025, the 13th Energy Storage International Conference and Expo (ESIE 2025) opened in Beijing.

Wang Xuefei, Deputy General Manager of SVOLT Energy Storage Product Management Center, delivered a keynote titled “Thermal-Composite Flying Stacking + Short Blade Batteries: Defining the Optimal Solution for the Future of Energy Storage” on the ESIE 2025 forum, outlining SVOLT’s technology breakthroughs and real-world progress in energy storage battery segment.

Wang noted that SVOLT’s innovative combination of Short Blade batteries and thermal-composite Flying Stacking has become a benchmark solution for safer, more efficient energy storage, with broad verification across global applications.

Technology innovation: thermal-composite Flying Stacking breaks through industry bottlenecks

Since introducing the Short Blade Battery in 2019, SVOLT has continued to advance stacking manufacturing process, and launched its third-generation Flying Stacking technology in 2022. When integrated with thermal-composite processing, the stacking technology delivers a step-change upgrade for intelligent energy storage cell manufacturing.

By combining hot-press stacking of electrode plates, stable one-way conveying, and AI-powered inspection, the process solves long-standing issues associated with conventional winding—such as separator wrinkling and powder shedding. It boosts stacking efficiency to 0.125s per plate while enabling more even stress release inside the cell.

Wang emphasized: “thermal-composite Flying Stacking technology is a key path to scalable mass production of large-capacity energy storage cells and a key foundation for next-generation, higher-capacity energy storage systems.”

Leading Cell Innovation: Structural innovation built for all-scenario energy storage scenarios

SVOLT’s Short Blade cell design is centered on a long-and-thin architecture engineered to combine high energy density, high safety, and strong platform compatibility:

Safer: The double-sided liquid-cooling design keeps cell-to-cell temperature delta below 2°C, reducing thermal propagation risk by 80%. In addition, a “thermal–electrical separation” layout, with tabs and the rupture vent positioned on opposite sides, further strengthens protection against thermal propagation.

More Economical: The short blade architecture reduces connectors by 40% and improves grouping efficiency by 30%, supporting an estimated 10% reduction in upfront capex.

All-scenario coverage: The L500 350Ah cell is designed to serve utility-scale storage, commercial and industrial storage, and residential storage—advancing SVOLT’s all-scenario short blade roadmap. 

System upgrade: thermal-composite short blade energy storage cells reshape system value

Built on 350Ah thermal-composite Short Blade cells, SVOLT’s 268kWh commercial and industrial (C&I) energy storage system adopts an industry-first Short Blade CTR technology. Compared with peers, the system delivers 30% higher structural strength, reduces components by 36%, lowers direct material cost by 10%, and improves cycle life by more than 15%, supporting full-scenario response needs in C&I demands.

5MWh utility-scale energy storage system features 350Ah thermal-composite Short Blade cells, and an industry-first dual-layer liquid-cooling architecture for more precise temperature control. Compared with competitors, it increases full-life-cycle energy throughput by 10%, offering a robust solution for GWh-class energy storage power plants.

Until now, SVOLT’s Short Blade energy storage cells have already been deployed at scale across multiple energy storage projects worldwide. Its system products have entered markets across Europe, the Middle East and Africa, and Asia-Pacific, and SVOLT has also presented the BNEF Tier 1 supplier list.

In closing, Wang stated: “the future of energy storage must belong to innovators who remain committed to pushing technical boundaries. SVOLT will remain committed to build on thermal-composite Flying Stacking and Short Blade battery technologies to drive the next wave of energy storage innovation and bring Chinses wisdom and Chinese innovations to the global energy transition.”
