On April 9, CATL released the world’s first 5-year zero-degradation energy storage system that can be mass-produced - CATL Tianheng. CATL's Tianheng energy storage system integrates "zero decay in five years, 6.25 MWh, and multi-dimensional true safety", pressing the accelerator button for the large-scale application and high-quality development of new energy storage.
Ningde Times Tianheng Energy Storage System Released
The world's first 5-year zero-attenuation system, capable of mass production
Zero capacity degradation for five years is a milestone for long-life lithium batteries, but zero power degradation is also crucial for energy storage power stations committed to meeting the needs of new power systems. Ningde Times Tianheng energy storage system uses bionic SEI and self-assembly electrolyte technology to clear roadblocks for lithium ions, achieve zero attenuation of power and capacity in 5 years, and control the power consumption of auxiliary machinery throughout its life cycle without increasing, truly achieving "Frozen age" from the inside out.
With its leading R&D technology and extreme manufacturing capabilities, CATL has successfully solved the problem of high lithium metal activity in "zero attenuation" batteries, effectively curbed the thermal runaway phenomenon caused by oxidation reactions, and achieved large-scale mass production of zero attenuation systems within 5 years.
20 feet 6.25 MWh, small space contains high energy
Ningde Times Tianheng energy storage system achieves high energy of 6.25 MWh in a standard 20-foot container. The energy density per unit area is increased by 30%, and the total station area is reduced by 20%. The energy density is upgraded within a square inch. Create higher benefits.
Powerful performance starts from the "core". CATL's Tianheng energy storage system is equipped with L series products dedicated to long-life zero-attenuation battery cells for energy storage, achieving the ultra-high energy density of lithium iron phosphate energy storage batteries - 430Wh/L.
Dedicated quality management system for energy storage to build ultimate safety
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, testing and verification, operation monitoring, and safety failure analysis. This system sets different security goals based on application scenarios and then develops corresponding security technologies based on the goals. In order to ensure the effectiveness of the technology, CATL has built a safety demonstration platform to simulate the safety demonstration of energy storage systems in different power grid scenarios and operating environments. After the project was put into operation, CATL continuously monitored the operating status through AI risk monitoring and intelligent early warning, and used the PSA model to quantify the failure probability of the energy storage product throughout its life cycle, thereby verifying the safety design goals and continuously updating them.
CATL's Tianheng energy storage system's battery cell failure rate has reached an industry-leading PPB level, which extends to the operation of the entire life cycle and the entire chain, which can effectively reduce operating costs and bring about a significant improvement in the entire life cycle IRR.
Energy storage is a key part of energy reform and electric power transformation. CATL has always been committed to providing first-class energy storage solutions to the world. The launch of the 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 collaborate 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.
