Large capacity, zero attenuation, CATL Tianheng energy storage system released

On April 9, CATL released the world's first energy storage system with zero attenuation for 5 years and mass production - CATL Tianheng. The CATL Tianheng energy storage system integrates "zero attenuation for 5 years, 6.25 MWh, and multi-dimensional true safety", accelerating the large-scale application and high-quality development of new energy storage.

CATL Tianheng Energy Storage System Launched

The world's first 5-year zero-attenuation system, ready for mass production

Zero capacity decay over five years is a milestone for long-life lithium batteries, but zero power decay is also crucial for energy storage power stations that are committed to meeting the needs of new power systems. CATL's Tianheng energy storage system uses bionic SEI and self-assembling electrolyte technology to remove obstacles for lithium ions, achieving zero power and capacity decay over five years, and controllable auxiliary power consumption throughout the life cycle without growth, truly achieving "freezing age" from the inside out.

With its leading R&D technology and extreme manufacturing capabilities, CATL has successfully solved the problem of the high activity of lithium metal in "zero-degradation" batteries, effectively curbed the thermal runaway caused by oxidation reactions, and achieved large-scale mass production of 5-year zero-degradation systems.

20 feet 6.25 MWh, high energy in a small space

CATL's Tianheng energy storage system achieves a high energy of 6.25 MWh in a standard 20-foot container, increases energy density per unit area by 30%, and reduces the entire station's footprint by 20%, achieving an upgrade in energy density in a small space and creating higher benefits.

Powerful performance starts from the core. CATL Tianheng energy storage system is equipped with L series products of long-life zero-attenuation battery cells dedicated to energy storage, achieving the ultra-high energy density of lithium iron phosphate energy storage batteries - 430Wh/L.

Energy storage-specific quality management system to build ultimate safety

In order to achieve the goal of ultimate safety of energy storage, CATL has established a dedicated quality management system for energy storage based on a complete cycle of technology development, test verification, operation monitoring, and safety failure analysis. The system sets different safety goals based on application scenarios, and then develops corresponding safety technologies based on the goals. To ensure the effectiveness of the technology, CATL has built a safety verification platform to simulate the safety verification of energy storage systems in different power grid scenarios and operating environments. After the project is put into operation, CATL continuously monitors the operating status through AI risk monitoring and intelligent early warning, and uses the PSA model to quantify the failure probability of energy storage products throughout their life cycle, thereby verifying the safety design goals and continuously updating them.

The single cell failure rate of CATL's Tianheng energy storage system has achieved the industry-leading PPB level, which extends to the operation of the entire life cycle and the entire chain, can effectively reduce operating costs and bring about a significant improvement in the IRR of the entire life cycle.

Energy storage is a key link in energy reform and power transformation. CATL has always been committed to providing first-class energy storage solutions to the world. The launch of CATL Tianheng Energy Storage System is another landmark practice of CATL in assisting energy transformation. In the future, CATL will continue to uphold the concept of open innovation and sincerely cooperate with global industry chain partners to achieve win-win results. Use innovation to promote high-quality development of the industry; use technology to build a zero-carbon society and life.
