2. TENER uses biomimetic SEI and self-assembled electrolyte technologies to achieve zero degradation in both power and capacity, creating an “ageless” energy storage system.
3. CATL has established a quality management system to ensure ultimate safety in energy storage, reducing failure rates to PPB level and enhancing IRR.
CATL has introduced TENER, a 6.25-MWh energy storage system that has shown zero degradation in its first five years of use. This advancement is crucial for increasing the lifespan of batteries and meeting the needs of new electric power systems. TENER uses biomimetic SEI and self-assembled electrolyte technologies to prevent degradation of power and capacity, ensuring minimal auxiliary power consumption throughout its life cycle.
The company has successfully addressed challenges related to highly active lithium metals in zero-degradation batteries, which helps prevent thermal runaway. TENER has a 30% increase in energy density per unit area and a 20% reduction in overall station footprint, enhancing energy density and efficiency within a limited space. It uses long-lasting and zero-degradation LFP cells tailored for energy storage applications, achieving an energy density of 430 Wh/L.
To ensure ultimate safety in energy storage, CATL has developed a quality management system that includes technology development, proof testing, operation monitoring, and safety failure analysis. They have set specific safety goals for different scenarios and continuously monitor the operation status of energy storage systems using AI-powered risk monitoring and intelligent early warning systems. By reducing the failure rate to the PPB level for cells used in TENER, CATL aims to lower operating costs and improve the internal rate of return.
