Water-based Ion Battery: A New Path for Battery Technology Development
With the development of smart grids and the continuous renewed market share of renewable energy, more demands are placed on large-scale secondary energy storage technologies. According to McKinsey's forecast, by 2025, the total global electricity storage market will exceed $1 trillion.
Whether it is distributed energy storage or centralized energy storage, energy storage devices of several megawatt-hours to several hundred megawatt-hours are needed. Currently, the more common energy storage methods are pumped storage and battery storage, and pumped storage is affected by geographical conditions. Larger restrictions, general areas do not have installation conditions, battery energy storage flexibility, is the first choice for future energy storage.
Although there are various types of batteries on the market today, none of them can completely meet the needs of the energy storage market. Most types of batteries also have problems such as high price, short life, and insufficient safety. It can be said that all over the world, researchers in the field of batteries are looking for a cheap and long-lived electrochemical energy storage solution. The E series of water-system ion batteries and battery stacks recently released by Enli Energy Technology Co., Ltd., as well as battery modules and MW-level battery rack systems made of battery stacks, are expected to give a new path.
It is understood that after years of research and development, Enli Energy has possessed more than 30 core patents with independent intellectual property rights in water-based ion battery research and technology, successfully breaking through battery materials, and solving problems in battery production processes and production equipment, etc. Dozens of major technical problems have produced product-based, practical water-based ion battery stacks and module products. It is the first domestic company to industrialize water-based ion batteries.
Judging from the technological innovation point of view, Dr. Che Yong, vice president of Enli Energy, introduced that water-based ion batteries have a clear advantage compared with the current mainstream storage products used in China, such as lead-acid and lithium-ion batteries. The first is safety, and the product does not contain Inflammable and explosive substances, without hazardous components, do not burn in fire, and are not blown by external strong blows; followed by long life, at present, the product cycle life has reached more than 3500 times, close to 100% deep discharge, the service life can be More than 10 years. Again, it is low cost, and the main raw materials such as manganese and carbon are extremely rich in reserves and easy to prepare, and there is ample room for cost reduction.
In addition, the water-based ion battery adopts neutral saline electrolyte, which is acid-free. The entire process of production, use, and recycling is non-polluting. The used materials can also be recycled for secondary use. At the same time, it is scalable, and its modules are used. The product design, from the unit to the combined application, is not limited in scope, and can be configured both on-grid and off-grid, providing technical support from the source for the country to promote the establishment of a distributed microgrid.
At the same time, Dai Li, president of Enli Energy, introduced that the E-series water-based ion battery stack adopts a modular design, a tool-free connection method, a single battery stack capacity of 3 kWh, and can be conveniently stacked into a 40 kWh battery module and a centralized capacity of 1 MWh. Battery shelf.
“In order to tie in with the application of the products, we have also introduced battery management systems that match different application industries and scenarios, such as Agilis-3 1000 series residential photovoltaic energy storage systems, Agilis-3 2000 series small commercial energy storage systems and MW. The total energy storage and microgrid solutions include home, commercial, and large-scale energy storage applications. They can be used to increase the voluntary self-use rate of photovoltaic power generation, solve power consumption in remote and unpowered areas and unstable power grids, and smooth the large-scale photovoltaic power plants. Output, grid cuts, etc.," said Dai Xiang.
Currently, Enli Energy has announced strategic cooperation with Thailand Enserv Co. Enserv Co is a new energy power operator in Southeast Asia headquartered in Bangkok, Thailand. Dai Xiang said that both parties will promote the photovoltaic energy storage microgrid solution based on Enli Energy's ion battery technology and products for the needs of the Southeast Asian and Indian markets. This will be the first step for Enli's water series ion battery products to go abroad. . With the industrialization of Enli Energy's energy storage technology and the promotion and application of its products, it will provide stable, sustainable and green renewable energy resources for the power shortage regions such as Southeast Asia and India.
