On April 9th, CATL officially launched its new product, the Tianheng containerized energy storage system, boasting a capacity of 6MWh. It marks the world's first energy storage system with zero decay over a five-year period.
According to the description, one of the key highlights of the Tianheng energy storage system is its use of biomimetic SEI (Solid Electrolyte Interphase) and self-assembling electrolyte technology, ensuring "zero degradation" in capacity and power over five years.
The containerized energy storage system measures approximately 6 meters in length, with widths and heights of 2.4 meters and 2.8 meters, respectively.
For a 200MWh power station, the footprint of this storage equipment is 4465 square meters, representing a 20% reduction in area compared to the previous generation 5MWh containerized energy storage system from Ningde era.
In terms of battery cells, Tianheng Energy Storage System adopts the NCM (Nickel-Cobalt-Manganese) long-life battery cells from CATL (Contemporary Amperex Technology Co. Limited). These cells boast an energy density of 430Wh/L, marking a 30% increase in energy density per unit area.
Dr. Wu Kai, Chief Scientist at CATL, stated, "Energy storage, as infrastructure, is characterized by the need for operation over 10 or 20 years, under various complex environmental and application conditions, ensuring safe, stable, and high-quality operation."
As the "king" of power batteries for China's new energy vehicles, energy storage systems have gradually become an important business segment for CATL.
According to financial reports, in 2023, CATL's revenue from energy storage battery systems increased by 33.17% year-on-year to 59.9 billion CNY, accounting for 14.94% of total revenue. The energy storage business has become CATL's second-largest source of revenue.
