In a remarkable breakthrough, TENER has introduced the world’s first energy storage system that promises zero capacity degradation over an impressive five-year period. This innovation stands to considerably extend the lifespan of batteries, which is a boon for energy storage facilities servicing new generation electric power systems.
The ingenuity behind TENER’s enduring battery system stems from the utilisation of biomimetic SEI (solid electrolyte interphase) alongside self-assembled electrolyte technologies. These advancements have been instrumental in eliminating the common obstacles to the smooth passage of lithium ions. The result is an energy storage system that not only retains its power and capacity intact over time but also completely avoids the growth of auxiliary power consumption throughout its lifecycle. CATL terms this the creation of an “ageless” energy storage solution.
Tackling one of the major hazards in battery technology, CATL’s advanced approach has triumphed over the potential dangers posed by the reactive nature of lithium metals. By effectively nullifying the risk of thermal runaway from oxidation reactions, the company has set a new standard for safe, zero-degradation power sources.
Supercharged storage in a compact design
The TENER system embodies impressive energy provision within confined spaces, boasting a capacity of 6.25 MWh housed within a standard 20-foot container. This represents a 30% increase in the energy-per-unit-area available, and a consequential 20% reduction in space requirements. Such advances distinguish TENER as a leader in efficiently packaged, high-density energy storage.
At the heart of TENER’s robust performance lie CATL’s bespoke energy storage cells, which deliver an energy density of 430 Wh/L – an unprecedented figure for LFP batteries within the realm of energy storage use.
Unwavering commitment to safety standards
End-to-end safety has been a foremost priority for CATL, manifesting in the establishment of a comprehensive quality management system. This protocol stretches from technological development to operation oversight, including rigorous proof testing and detailed safety failure analysis. Safety objectives are tailored to respective applications, with innovative security measures engineered accordingly.
To validate and ensure the integrity of these safety technologies, CATL has developed simulation platforms capable of emulating various power grid scenarios. Upon deployment, AI-fuelled monitoring and intelligent predictive systems constantly survey operational status. This allows for the precise calculation of lifecycle failure rates of the TENER products, reaffirming the design’s safety objectives while enabling continual optimisation processes.
By reducing the cell failure rate to the PPB (parts per billion) level, the TENER system not only guarantees operational excellence but also delivers on the promise of reduced operational expenses and an elevated internal rate of return (IRR).
Energising the green transition
Energy storage solutions like TENER are critical to the accelerating shift towards green energy. CATL maintains a resolute dedication to supplying world-leading energy storage solutions to an international customer base. The launch of TENER marks yet another testament to CATL’s unwavering commitment to the energy transition. With eyes fixed on the future, CATL continues to push the boundaries of open innovation and industry collaboration— cementing its position as a champion of progress and a pioneer of cutting-edge technology in the renewable energy sector.
