Tianmu Lake Institute of Advanced Energy Storage Technologies

Tianmu Lake Institute of Advanced Energy Storage Technologies (TIES), formally Tianmu Lake Advanced Energy Storage Technology Research Institute Co., Ltd., is a Chinese research institute and technology service provider dedicated to advanced electrochemical energy storage. It was jointly founded in 2017 by the People's Government of Liyang City and the Institute of Physics of the Chinese Academy of Sciences, and is located in Liyang, Changzhou, Jiangsu Province. Academician Chen Liquan serves as honorary president, while researcher Li Hong is the founder and chief engineer. In 2025, China Green Development Investment Group Co., Ltd. was introduced as an investor to accelerate the company's development. The institute positions itself around the major national needs and the main battlefield of the national economy, aiming to gather wisdom for original innovation, develop intelligent manufacturing, and lead the energy storage industry. Its corporate vision is to establish the world's premier enterprise specializing in solid-state electrochemical energy storage technology services. TIES operates through several service lines, including test and failure analysis, process engineering, frontier development, intelligent manufacturing, and technical services. It also runs collaborative programs such as a collaborative model, R&D labs, a scientist's workshop, startup company incubation, and cooperative cultivation. The first phase of the TIES project represents a total investment of 500 million yuan, with a total site area of approximately 51,000 square meters. The institute serves the energy storage industry by providing testing, failure analysis, process engineering, and intelligent manufacturing support, and by incubating startups. Among its incubated companies are Liyang Deepwater Technology Consulting Co., Ltd., founded in June 2018, which provides technology, industrial, and policy consulting as well as conferences and training in the energy storage field, and Jiangsu Yili Technology Co., Ltd., which focuses on R&D, production, and sales of cathode materials for lithium-ion batteries, including nickel-cobalt-manganese ternary materials, high-voltage lithium cobaltate, and ternary precursors. TIES presents itself as a bridge between fundamental research and industrial application in energy storage, emphasizing respect for originality and talent, modesty, prudence, and first-class ability. Its activities span testing and failure analysis, process engineering, frontier technology development, intelligent manufacturing, and technical services, with a strong focus on solid-state electrochemical energy storage. The institute is active in China's energy storage ecosystem, contributing to the development of lithium-ion batteries, lead-acid batteries, flow batteries, supercritical compressed air, and supercapacitors, and addressing the need for high energy, high power, long life, high safety, and low cost in energy storage technologies.
