[GEM Releases New Preparation Method for Modified High-Nickel Precursors] GEM Co., Ltd. and its Shenzhen Super Green Technology Research Center recently disclosed an invention patent involving a modified high-nickel precursor, its preparation method, and cathode materials. The patent (CN202411457862.7) was filed on October 18, 2024, and published on January 21, 2025.

This invention introduces a modified complexing agent solution containing ammonium lignosulfonate during the co-precipitation reaction, significantly enhancing particle dispersibility and sphericity. Additionally, this method expands the precursor lattice constant and improves lithium-ion diffusion kinetics, thereby increasing the charge-discharge capacity, C-rate performance, and cycling stability of cathode materials. This innovative technology is expected to bring significant breakthroughs to the lithium battery industry, driving the development of the NEV and ESS sectors.

[SMM Stainless Steel Flash] April 16, 2026: Stainless Steel Market Highlights

On April 16, 2026, the stainless steel market saw major shifts. The EU's move to cut quotas by 47% and double tariffs to 50% in July triggered panic buying in Europe. India extended BIS certification until late September to ensure supply flexibility. Supported by Indonesia’s HPM formula adjustments, export prices remain firm, with slight gains in Foshan 304 spot prices. Rising logistics costs due to Middle East tensions and new trade barriers are collectively pushing up global trade expenses.

【SMM Nickel Flash News】Scenario Simulation and Comparative Analysis of Saprolite and Limonite under the New HPM Formula

【SMM Nickel Flash News】Given the significant variance in byproduct quality across nickel ore deposits, establishing a unified HPM for each grade remains a challenge. Consequently, SMM has developed multiple scenarios for both saprolite and limonite to serve as a benchmark for the new HPM formula and to provide a comparative analysis against SMM’s proprietary pricing

[SMM Stainless Steel Flash] New Indonesian Nickel Pricing Formula to Surge Costs for Stainless Steel Sectors

Indonesia’s Ministry of Energy and Mineral Resources (ESDM) revised the HPM nickel ore formula in Quarter 2 of 2026, significantly raising the adjustment factor and including cobalt, iron, and chromium in pricing for the first time. This shift will increase base prices across all grades, particularly for low-grade ores used in hydrometallurgy, placing heavy cost pressure on the stainless steel and new energy industries. Supply remains tight due to delayed mining quota approvals and rising refining costs. Following the policy signal, international nickel futures have surged through key resistance levels. Analysts suggest that high raw material costs may become the new norm, with potential for further price hikes if refined nickel output drops or policy impacts exceed market expectations.
