On October 15, the 140th China Import and Export Fair (Canton Fair) opened in Guangzhou. Marking the 70th anniversary of the Canton Fair, this year's event highlights innovation, sustainability, and smart technologies, reflecting emerging trends in industrial development and the global green transition.

At the exhibition, Tianneng presents a diversified portfolio of motive power and energy storage solutions, spanning lead-acid, lithium-ion, sodium-ion, and semi-solid-state battery technologies. Building on its established industrial strengths, Tianneng continues to advance emerging battery technologies and expand its solutions across a wider range of energy applications.

Comprehensive Energy Storage Portfolio: TNPOWER Liquid-Cooled All-in-One Systems for C&I Applications

A key highlight of Tianneng's exhibition is the TNPOWER 261kWh C&I Energy Storage Cabinet, available in both lithium-ion and semi-solid-state configurations. These two technology options offer greater flexibility to meet diverse C&I energy storage requirements and have attracted significant attention from leading media outlets at the exhibition.

The lithium-ion configuration features 314Ah lithium iron phosphate (LFP) cells and integrates a liquid cooling system with an Energy Management System (EMS), delivering a cycle life of up to 8,000 cycles. Its all-in-one design enables rapid deployment and flexible capacity expansion, making it suitable for commercial and industrial facilities such as small factories and supermarkets. Through peak shaving and load shifting, the system helps optimize electricity consumption and reduce operating costs.

The semi-solid-state configuration adopts an optimized electrolyte system with reduced liquid electrolyte content, exploring further improvements in cell safety and energy density. This provides an additional technology option for commercial and industrial energy storage applications.

Tianneng also showcases its 5MWh utility- scale BESS, residential lithium-ion energy storage solutions, and telecom energy storage products. Together, these offerings address applications ranging from utility-scale power stations and households to telecommunications infrastructure, demonstrating Tianneng's comprehensive energy storage portfolio.

Advancing Lithium-Ion and Sodium-Ion Technologies to Expand Motive Power Applications

As electric mobility and emerging equipment applications continue to evolve, battery requirements are becoming increasingly diverse and specialized. Lithium-ion batteries continue to support a broad range of motive power applications, while sodium-ion technology offers additional possibilities for both motive power and energy storage.

Tianneng's sodium-ion battery development focuses on the polyanionic technology pathway, supported by in-house R&D and manufacturing capabilities for NFS and NFPP cathode materials. Its battery cells achieve a discharge capacity retention rate of over 90% at -20°C, addressing application requirements for low-temperature operation, high-rate performance, and long cycle life.

Tianneng's sodium-ion battery portfolio now covers a wide range of applications, including motorcycle starting batteries, automotive start-stop systems, lightweight electric motorcycles, backup power for telecom base stations, energy storage for ultra-fast EV charging, and large-scale energy storage systems. These applications further expand the potential of sodium-ion technology across the motive power and energy storage sectors.

Building on Established Strengths to Drive Diversified Energy Innovation

Alongside its latest battery technologies and energy storage solutions, Tianneng also showcases its established product portfolio, including lead-acid motive power batteries, lead-acid UPS batteries, and automotive starting batteries. These products serve a broad range of applications, from electric mobility and backup power to automotive starting systems.

From proven lead-acid technologies to lithium-ion and sodium-ion batteries and integrated energy storage systems, Tianneng continues to build on its industrial expertise while advancing technological innovation and expanding application possibilities. Through its diversified product portfolio, Tianneng remains committed to delivering reliable energy products and solutions that address the evolving needs of global markets.
