CATL Introduces TENER: World's First Five-Year Zero-Degradation Energy Storage System with 6.25MWh Capacity

On April 9th, CATL revealed TENER, the world's inaugural mass-producible energy storage system boasting zero degradation within its initial five years of operation, in Beijing, China. With comprehensive safety features, a five-year lifespan free of degradation, and a robust 6.25MWh capacity, TENER is poised to accelerate the widespread adoption of new energy storage technologies and propel the sector toward higher quality standards.

Pioneering Mass-Production of Zero-Degradation Systems

While maintaining capacity over the first five years of use marks a significant leap forward in battery lifespan extension, ensuring zero degradation of power is equally crucial for energy storage power plants seeking to align with the demands of emerging electric power systems. By harnessing biomimetic SEI (solid electrolyte interphase) and self-assembled electrolyte technologies, TENER has overcome barriers to lithium-ion movement, achieving zero degradation in both power and capacity. This guarantees consistent auxiliary power consumption levels throughout its entire lifecycle, effectively creating an "ageless" energy storage solution.

Empowered by state-of-the-art technologies and advanced manufacturing capabilities, CATL has addressed challenges posed by highly reactive lithium metals in zero-degradation batteries, thereby mitigating thermal runaway risks stemming from oxidation reactions.

Unmatched Energy Density in a Compact Form: 20-foot Container housing 6.25MWh Capacity

TENER boasts an impressive 6.25MWh capacity within a TEU container, marking a 30% increase in energy density per unit area and a 20% reduction in overall station footprint. This innovative design enhances energy density and efficiency within limited spatial constraints.

CATL's cutting-edge cell technology underpins the system's outstanding performance. TENER is equipped with long-lasting, zero-degradation cells tailored for energy storage applications, achieving an impressive energy density of 430 Wh/L, a significant milestone for LFP batteries used in energy storage.

Dedicated Quality Management for Ultimate Safety

In pursuit of ultimate safety in energy storage, CATL has established an end-to-end quality management system encompassing technology development, proof testing, operation monitoring, and safety failure analysis. Tailored safety goals are set for different scenarios, with corresponding safety technologies developed to meet these objectives. To validate these technologies, CATL has created a validation platform simulating safety tests for energy storage systems across various power grid scenarios. Post-deployment, CATL continuously monitors system operation via AI-powered risk monitoring and intelligent early warning systems, calculating product failure rates throughout their lifecycle to refine safety design goals.

CATL has reduced cell failure rates to parts per billion levels for TENER, translating to lower operating costs and significantly enhanced internal rates of return when extended over the system's full lifecycle.

Energy storage plays a pivotal role in the green energy transition, and CATL is committed to delivering world-class solutions to customers globally. The introduction of TENER marks another milestone in CATL's ongoing commitment to energy transition. Looking ahead, CATL will continue its dedication to open innovation, collaborating with industry partners worldwide to lead the charge in innovation and advanced technology.
