CORNEX Showcases Next-Gen LFP and Sodium-Ion Battery Tech at Tianjin EV Expo

Battery manufacturer CORNEX recently took center stage at the 24th China North International Bicycle and E-bike Exhibition in Tianjin, held from March 27 to 29. The company utilized the expo to debut its latest cylindrical battery technologies and energy storage solutions explicitly tailored for the light electric vehicle (EV) sector.

Drawing significant attention at the event was the firm's newly developed 45Ah lithium iron phosphate (LFP) battery, engineered specifically for electric motorcycles. Industry observers noted several performance milestones for this unit: it boasts 2.5C ultra-fast charging capabilities—reportedly hitting 70% capacity within a 15-minute window—alongside a 2C continuous and 5C peak discharge rate. Characterized by a mass energy density surpassing 190Wh/kg and a projected lifecycle of over 3,000 charges, the 45Ah model aims to deliver a resilient and safe power source for the rapidly expanding e-motorcycle demographic.

Expanding upon the market success of its standard 20Ah unit, CORNEX has also widened its portfolio with new 30Ah and 50Ah variants intended for low-speed vehicles (LSVs). Slated to enter mass production later this year, these optimized power cells are designed to accommodate the varied range and performance requirements of both two- and four-wheeled electric transit.

Addressing the industry-wide challenge of battery degradation in sub-zero climates, the company also rolled out a fresh line of sodium-ion cylindrical batteries, available in 10Ah, 16Ah, and 26.5Ah capacities. Engineered for severe operational environments, these units reportedly maintain over 91% of their charge even in -40°C conditions. With a substantial 10,000-cycle rating and aggressive cost-efficiency, analysts view these sodium-ion options as highly suitable for heavy-duty commercial networks, such as ridesharing fleets and battery-swapping stations.

Supported by an upgraded smart manufacturing infrastructure, CORNEX appears positioned to rapidly accelerate its light EV battery output. Moving forward, the enterprise states it will maintain its dual-track focus on advancing both LFP and sodium-ion architectures to support the global transition toward sustainable green mobility.
