新能源周报：双硅回归基本面，锂矿停产靴子落地-20250811

1. Report Industry Investment Ratings - Industrial Silicon (SI): Oscillating [8][9] - Polysilicon (PS): Oscillating [10] - Lithium Carbonate (LC): Bullish [87] 2. Core Views of the Report - The supply of industrial silicon is expanding due to continuous resumption of production in factories in the northwest and southwest regions, while downstream polysilicon and silicone production has increased. The resumption of supply will impact the supply - demand balance, and the futures price is expected to be weak in the short term [9]. - For polysilicon, the national weekly production has increased, downstream silicon wafer production is on the rise, but market sentiment has cooled. The futures price is expected to oscillate, with cost support and large - factory price - holding at the lower end and downstream weakness and hedging pressure at the upper end [10]. - Regarding lithium carbonate, the mine - end production halt has been confirmed, and if there is rectification and resumption after compliance, considering the large downstream inventory and supplementary supply from surrounding mines, the impact on the balance sheet is limited. Market sentiment may trigger downstream stocking, and the price is expected to be strong in the short term [87]. 3.
