On April 9, Ningde Times released Tianheng, the world's first energy storage system with zero attenuation in 5 years and capable of mass production. Ningde Times Tianheng Energy Storage System (hereinafter referred to as "Tianheng Energy Storage System") integrates "5 years of zero attenuation, 6.25 MWh, and multi-dimensional true safety", which is a large-scale application and high-quality development of new energy storage. Press the accelerator button.

Let the batteries "freeze age" and let the life of lithium batteries no longer "dive". Xu Jinmei, CTO of Ningde Times Energy Storage Division and President of Energy Storage Europe Business Division, pointed out at the press conference that the Ningde Times Tianheng series successfully solved the problem of high activity of lithium metal in "zero-attenuation" batteries and achieved 5 years of power and capacity. Long-life lithium battery with zero attenuation.

The world's first five-year zero-attenuation system, capable of mass production

With its leading R & D technology and extreme manufacturing capabilities, Ningde Times successfully solved the problem of high activity of lithium metal in "zero-decay" batteries, effectively curbed the thermal runaway caused by oxidation reactions, and achieved mass production of zero-decay systems for 5 years.

This year, the work report of the two sessions first mentioned "new energy storage", which involves the goal of carbon peak carbon neutralization, the energy revolution and the construction of a new energy system, all of which provide a solid policy foundation for the development of the energy storage industry. Energy transformation requires that the energy storage system should be really put into use and play an important role in the energy system. This also means that the development trend of the energy storage industry is also from the incremental expansion in the past to the pursuit of product quality and technology improvement. The competition in the future will depend more on the technological innovation capability of enterprises and the "hard power" of products. Enterprises need to provide stable, reliable and cost-effective energy storage solutions, which is the key to win the market. Five-year zero attenuation of capacity is a milestone for long-life lithium batteries, but it is also crucial for energy storage plants dedicated to meeting the needs of new power systems. Tianheng energy storage system adopts bionic SEI and self-assembled electrolyte technology to remove roadblocks for lithium ion, achieve zero attenuation of power and capacity for 5 years, the whole life cycle of auxiliary power consumption can be controlled and does not increase, and truly achieve the "freezing age" from the inside to the outside.

Global energy storage industry trend forecast report in 2024 predicts:In 2024, 300+Ah large cells and 5 megawatt hour energy storage systems will be the mainstream of the industry. As of the release of Tianheng Energy Storage System, the highest energy storage system in the industry has reached 6 megawatt hours in a 20-foot container. The Tianheng Energy Storage System achieves a high energy level of 6.25 megawatt hours in a standard 20-foot container, increases the energy density per unit area by 30%, and reduces the floor area of the entire station by 20%. The energy density is upgraded within every inch. Create higher benefits.

Powerful performance starts with the "core". Tianheng Energy Storage System is equipped with long-life zero-attenuation cells L series products dedicated 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

In order to achieve the goal of extreme safety of energy storage, Ningde Times has established a special quality management system for energy storage based on the complete cycle of technology development, test verification, operation monitoring and safety failure analysis. The system sets different security goals based on application scenarios, and then develops corresponding security technologies according to the goals. In order to ensure the effectiveness of the technology, Ningde Times 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 is put into operation, Ningde Times continuously monitors the operation status through AI risk monitoring and intelligent early warning, and uses PSA model to quantify the failure probability of energy storage products in the whole life cycle, so as to verify the safety design objectives and continuously update them.

The battery cell failure rate of Tianheng Energy Storage System has reached the industry-leading PPB level and is extended to the entire life cycle and the entire chain operation, which can effectively reduce operating costs and bring about a significant improvement in the entire life cycle IRR.
