CALB Semi-Solid-State Battery Expands to Light Trucks with 400 Wh/kg Energy Density

Deployment of advanced battery systems is no longer limited to passenger vehicles, as commercial applications begin to integrate next-generation energy storage solutions. The CALB semi-solid-state battery has now entered the light truck segment, signaling a shift in how commercial fleets approach performance, safety, and operational efficiency. This transition reflects a broader push toward scalable electrification, where innovations once considered premium are becoming viable for logistics and transport use cases. The move also strengthens the role of China in accelerating battery technology adoption across diverse vehicle categories.

Expansion of Semi-Solid-State Batteries into Commercial Vehicles

CALB introduced its solid-liquid hybrid battery at a commercial vehicle exhibition, marking one of the earliest large-scale integrations of semi-solid-state technology in light trucks. The system is already being deployed in vehicles produced by Chery Automobile, demonstrating readiness for real-world applications. Unlike conventional lithium-ion batteries, this hybrid approach combines liquid and solid electrolytes to deliver improved safety without compromising energy density. The transition from passenger vehicles to light commercial vehicles highlights the scalability of this innovation and its ability to meet demanding operational requirements.

Performance Gains in Energy Density and Payload Efficiency

The CALB semi-solid-state battery achieves an energy density of 400 Wh/kg, representing a significant improvement over traditional liquid lithium batteries. This advancement directly enhances driving range while reducing overall battery weight. For light trucks, where payload capacity is a critical factor, lighter battery systems translate into higher cargo efficiency and better economics for fleet operators. This development aligns with broader industry efforts in Electric Vehicle Technology, where optimizing energy storage without adding weight remains a key engineering challenge.

Safety and Reliability Enhancements

Safety remains a central focus for commercial vehicle electrification, particularly in demanding logistics environments. The battery system has successfully passed 44 safety tests, including thermal propagation, fire resistance, and mechanical stress scenarios. These results exceed current regulatory benchmarks and reinforce confidence in semi-solid-state chemistry. Enhanced safety features reduce operational risks and extend lifecycle reliability, which is critical for fleet operators managing large-scale deployments. Such advancements contribute to the evolution of Battery Safety Standards across the industry.

Fast Charging and Low-Temperature Performance

Charging efficiency is another major advantage, with the battery supporting 2C fast charging capability. This allows charging from 30% to 80% in approximately 15 minutes, significantly reducing downtime in high-frequency logistics operations. Additionally, the battery demonstrates strong low-temperature performance, maintaining operational efficiency even at -25°C with over 20% range improvement compared to conventional systems. These features are particularly valuable for distribution networks operating across varied climatic conditions and align with advancements in EV Charging Infrastructure.

Market Position and Future Outlook

CALB continues to expand its footprint in advanced battery technologies, including applications in emerging sectors such as flying vehicles through collaborations with companies like Aridge. In the domestic market, the company holds a competitive position, ranking among the top battery manufacturers. However, the landscape remains dominated by industry leaders, with CATL and BYD maintaining a strong combined market share. As semi-solid-state technology matures, its adoption across commercial vehicles, special-purpose transport, and future mobility solutions is expected to accelerate, reshaping the competitive dynamics of the battery industry.
