Chinese manufacturer Tianjin Binhai Energy & Development (Binhai Energy) has abandoned a major solar project and shifted its focus toward the lithium battery materials sector, according to a source report published on 2026-05-09. The company formally ended its planned 15-gigawatt ingot pulling and photovoltaic cell manufacturing project, reallocating resources to silicon-carbon anode materials.
The decision was approved by the board of directors through a proposal to terminate the investment and construction of the ingot pulling and solar cell project. The original plan, announced in 2024, envisioned a combined 10-gigawatt ingot pulling and 5-gigawatt cell production facility in Baotou, Inner Mongolia. Although some environmental, energy, and land preparations were completed after initial approval, construction never began. When photovoltaic industry chain prices collapsed in 2025, the company recorded substantial asset impairment provisions that year.
Binhai Energy cited changes in the overall photovoltaic industry, noting that new investments in the industrial chain now face significant uncertainty. With module prices falling below production costs and the broader industry experiencing losses, the company stated that proceeding with additional capacity expansion would be risky. The announcement indicated that Binhai Energy recently signed a revised investment framework agreement with the government of Tumd Right Banner, Baotou, Inner Mongolia. Under this revision, the original crystalline silicon photovoltaic project will be transformed into an integrated project producing industrial silicon, silane gas, porous carbon, and silicon-carbon anode materials. This includes a 2,000-ton-per-year silicon-carbon anode material project currently under construction, as well as a self-developed 1,000-ton-per-year porous carbon project underway in Xingtai.
In contrast to the oversupplied photovoltaic manufacturing sector, silicon-carbon anodes—a new generation of lithium battery materials—can significantly improve energy density and are approaching a demand surge, with gross margins far exceeding those of traditional solar modules. Binhai Energy’s core business is lithium battery anode materials. The company entered the photovoltaic industry in 2023 by announcing cell project investments, which ultimately ended in termination. Over the past few years, many non-photovoltaic companies—including those in real estate, textiles, and traditional energy—moved into the solar sector hoping to gain a competitive edge.
Since 2025, the industry has undergone a brutal consolidation phase, leaving new entrants facing losses as soon as production starts. According to statistics from the China PV Industry Association, dozens of cross-sector photovoltaic entrants have announced project terminations or asset sales since 2026. An industry insider commented that the photovoltaic industry has moved from a gold rush to a high-risk battlefield, where blind capacity expansion poses the greatest danger for entrants lacking cost advantages and core technologies. The source noted that Binhai Energy’s decision to cut losses redirects limited resources from low-efficiency to high-efficiency areas, aligning with the market economy’s principle of survival of the fittest.
