Lithium battery concept stock Tianji Co., Ltd. closed at a two-day limit-up on Friday, with the company’s cumulative maximum share price increase reaching 466% since its low point on April 9. On October 31, Tianji Co., Ltd. released an institutional research summary stating that the average selling price of lithium hexafluorophosphate in the third quarter of 2025 is relatively low, resulting in losses. However, the trend shows that the average selling price has been continuously rising. Prices without long-term contracts have increased significantly. Operationally, the company is operating at full capacity with minimal inventory. In terms of production capacity, the company produces over 3,000 tons per month, with expected shipments between 35,000 to 38,000 tons this year. A 25% market growth next year corresponds to shipments exceeding 50,000 tons. The planned project capacity of 15,000 tons is expected to undergo equipment customization and installation by the end of this year and will likely reach full operation next year.
In the institutional research summary, Tianji Co., Ltd. also mentioned new business developments, including product layouts in solid-state batteries. Significant progress has been made in lithium sulfide, with samples recently delivered to core customers. According to the plan, kilogram-level scaling will be conducted before the end of the year, and the pilot line is expected to be operational in the first half of next year. Meanwhile, the company plans to develop lithium-sulfur-phosphorus-chlorine products, with preparations underway. Additionally, small-scale trials are being conducted for positive electrode lithium supplements. An external incubation project involves a silicon-carbon anode enterprise with a hundred-ton scale pilot line, which is expected to be installed by the end of this year or in Q1 next year.

On October 29, the company released an institutional research summary stating that it has built a comprehensive channel system integrating online and offline operations to enhance brand awareness and market share.

Additionally, the company’s data center liquid cooling hose has been largely finalized and is undergoing market expansion through sample deliveries and participation in exhibitions. However, no large-scale orders have been received yet.

Hainan Free Trade concept stock Hainan Strait Shipping primarily operates roll-on/roll-off transportation services in the South China Sea centered around Hainan Province, with its cumulative maximum share price increase reaching 183% since April 9. On October 30, the company released an institutional research summary stating that preferential tax policies implemented in the Hainan Free Trade Port, including corporate income tax incentives, directly reduce the company’s operational costs. After the implementation of the Hainan sealing-off operation, a “first-line liberalization, second-line control” policy will be enforced, meaning goods moving in and out of Hainan will enjoy greater freedom and convenience. Under the principle of “everything not prohibited is permitted,” investment liberalization will attract more investors and partners to enter the Hainan market, promoting certainty in vehicle and passenger flow growth for the company. As infrastructure in Hainan improves, such as the completion of the island’s tourism highway, it will significantly attract self-driving tourists, driving the company’s main business.
