Semi-Solid-State EV Batteries Are Now Powering up Trucks and Flying Cars

Why It Matters

The rollout signals a shift toward higher‑energy, faster‑charging batteries that can lower costs and expand EV adoption across passenger, commercial, and aviation segments, reshaping competitive dynamics in the global battery market.

Key Takeaways

• SAIC mass‑produces semi‑solid‑state batteries for MG4 EV.
• CALB supplies semi‑solid batteries to Chinese light trucks.
• CALB’s R46 cells target eVTOLs like XPeng AEROHT X3.
• Energy density reaches 400 Wh/kg, enabling lighter commercial vehicles.
• 2C charging restores 30‑80% in ~15 minutes.

Pulse Analysis

The battery landscape is undergoing a rapid transformation as semi‑solid‑state chemistries move from prototype to production lines. SAIC’s MG Motor brand has already launched the MG4 equipped with a 53.95 kWh manganese‑based semi‑solid battery, positioning the model as the world’s first mass‑produced vehicle of its kind. By delivering a CLTC range of 530 km (330 miles) at a price of roughly $14,500, the technology demonstrates that higher energy density and faster charging can be achieved without a premium price tag. This milestone sets a new benchmark for mainstream manufacturers seeking to differentiate their EV portfolios.

Beyond passenger cars, the commercial sector is reaping the benefits of the same chemistry. Chinese battery maker CALB announced large‑scale deployment of semi‑solid batteries in Chery’s light‑truck lineup, touting an energy density of 400 Wh/kg and a 2C charge that lifts the state‑of‑charge from 30 % to 80 % in about 15 minutes. The cells also retain 20 % more range at –25 °C, addressing a long‑standing weakness of conventional lithium‑ion packs. With a 5.3 % global market share, CALB’s rapid scaling underscores the growing demand for lighter, longer‑range powertrains in logistics and delivery fleets.

The aviation‑grade off‑shoot of CALB’s semi‑solid platform, the R46 cylindrical cell, is already earmarked for eVTOL manufacturers such as XPeng’s Aridge project. Offering up to 350 Wh/kg, the battery meets the stringent weight‑to‑energy ratios required for vertical‑takeoff aircraft while preserving safety through a hybrid solid‑liquid electrolyte. Meanwhile, the company’s all‑solid‑state “WUJIE” line targets 430 Wh/kg, hinting at a future where fully solid electrolytes could dominate both ground and air mobility. As incumbents like CATL and BYD accelerate their own solid‑state programs, the race to commercialize next‑generation batteries is poised to reshape supply chains and investment flows across the entire electric‑vehicle ecosystem.
