On May 15, the market price of electrolytic cobalt rose Yuan 1,523/tonne to Yuan 423,364-426,409/tonne. In addition, the market prices of cobalt sulfate and cobalt chloride remained unchanged at Yuan 92,000/t-95,000/t and 113,000-118,000/t respectively.For cobalt sulfate, supported firmly by raw material costs, mainstream smelters have shown a clear intention to hold prices firm. However, downstream manufacturers had strong resistance to high prices, while quotes from small and medium-sized plants remained temporarily stable. Limited restocking occurred in the ternary precursor market, with some mainstream transaction prices falling below Yuan 90,000/tonne. Purchases from other downstream industries remained steady with transactions concluded. For cobalt chloride, transaction prices remained stable at around Yuan 115,000/tonne. Downstream Co3O4 producers showed weak acceptance of high-priced cobalt chloride, compounded by shrinking terminal orders and fewer market inquiries.
