Semi-solid-state batteries expand into light trucks with CALB innovation

Momentum is building around semi-solid-state batteries as their application extends into light commercial vehicles, signaling a shift in how advanced battery technologies are being adopted across segments. China continues to lead this transition, with new deployments demonstrating how these batteries can address operational demands beyond passenger mobility. The move highlights growing confidence in hybrid electrolyte systems, especially for logistics and urban distribution fleets where efficiency, safety, and durability directly influence total cost of ownership.

CALB introduces hybrid battery for light trucks

CALB recently unveiled a solid-liquid hybrid battery at a commercial vehicle exhibition in Hefei, marking a key milestone in scaling semi-solid-state batteries. The battery has already entered mass production and is being deployed in light trucks manufactured by Chery Automobile. This development represents one of the earliest large-scale integrations of such battery technology into commercial vehicles, broadening its real-world applicability and reinforcing its role as a bridge toward fully solid-state systems.

Energy density and payload efficiency gains

The hybrid battery achieves an energy density of 400 Wh/kg, representing a significant leap compared to conventional liquid lithium batteries. This improvement not only extends driving range but also reduces overall battery weight, a crucial factor for light trucks where payload efficiency directly impacts revenue generation. By optimizing weight-to-energy ratios, semi-solid-state batteries enable operators to carry more goods without compromising range, making them particularly suited for high-frequency logistics operations.

Enhanced safety and reliability standards

Safety remains a critical consideration for commercial vehicle electrification, and the battery has undergone 44 rigorous safety tests, including thermal propagation, fire resistance, and crush scenarios. These tests exceed the latest regulatory requirements in China, ensuring higher reliability under demanding operating conditions. The hybrid electrolyte design contributes to improved thermal stability, reducing risks associated with battery failures and enhancing lifecycle durability for fleet applications.

Fast charging and low-temperature performance

The battery supports 2C fast charging, enabling a charge from 30% to 80% in just 15 minutes. This rapid replenishment significantly improves vehicle uptime, which is essential for logistics and delivery services. Additionally, its performance in extreme cold conditions stands out, delivering over 20% better range at -25°C compared to traditional batteries. These capabilities make it highly adaptable across varying climates and operational scenarios, further strengthening its commercial viability.

Expanding applications beyond road transport

Beyond light trucks, CALB is accelerating its footprint in next-generation mobility segments, including aviation-grade batteries for flying vehicles. Its collaboration with emerging players in advanced mobility underscores the versatility of semi-solid-state batteries. Meanwhile, the broader battery market in China remains highly competitive, with leading players continuing to dominate installations while newer technologies gradually carve out their share.

As semi-solid-state batteries continue to mature, their transition into commercial vehicle segments marks a critical step toward wider electrification. Their ability to balance safety, performance, and cost positions them as a key enabler in bridging current lithium-ion systems with future solid-state innovations.
