On December 18, Hainan officially opened a new historical stage of the island's closure operation.
Global lithium battery giant Ningde Times has accelerated the layout of Hainan industrial and commercial energy storage through joint ventures, and 10 billion-level smart micro-grid and independent energy storage projects have been signed one after another. In July
2025, its joint venture company, Xiamen Xinneng'an, signed an agreement with Hainan Huihai Science and Technology.
In October, Wuhan Weineng Battery Asset Company, a joint venture between Ningde Times and other enterprises, also set up a new company in Chengmai, Hainan, covering energy storage technology and battery leasing. After the closure of
Hainan Island, enterprises importing raw materials, core components and production equipment needed for the production of energy storage systems from overseas will enjoy zero tariff treatment, which directly reduces the initial investment and production costs. What is
more attractive is the "processing value-added tariff-free" and preferential fiscal and taxation policies. Enterprises with high dependence on imports and high added value in the production of energy storage batteries have unprecedented economic feasibility in Hainan.
