U.S. automotive giant General Motors (GM) has announced an investment in U.S. startup Peak Energy and plans to advance the commercialization of sodium-ion batteries, primarily for energy storage systems (ESS), with deployment targeted after 2029. This marks the first meaningful entry of a non-Chinese automaker into the field and is prompting Korea’s battery industry to incorporate sodium-ion technology into its strategic priorities, even as it accelerates efforts to catch up in LFP. Unlike ternary batteries (NCM/NCA) and LFP, which rely on lithium, sodium-ion batteries use more abundant and lower-cost sodium as a substitute, offering advantages such as greater supply chain stability, better low-temperature performance, and enhanced safety—making them particularly suitable for large-scale energy storage applications. At the same time, increased volatility in lithium prices has further strengthened the cost competitiveness of sodium-ion batteries. Korean players including LG Energy Solution, Samsung SDI, and SK On have already accelerated their efforts, aiming to advance sample production or commercialization around 2027. Overall, GM’s entry signals that a technology pathway previously dominated by Chinese companies is becoming globalized, and it is likely to push Korean battery manufacturers to accelerate adjustments to their technology and product portfolios.

[SMM Cobalt Morning Meeting Summary] Refined Cobalt Stops Falling and Stabilizes, with Transactions Improving but Support Limited

SMM Cobalt Morning Brief: This week, the cobalt industry chain overall consolidated on a subdued note. Refined cobalt spot prices remained stable temporarily. Traders resumed offering, but transactions were still dominated by essential stockpiling, while end-use demand had not yet clearly recovered. Cobalt intermediate products were boosted by news related to DRC. Miners' offers stayed firm, but downstream smelter acceptance was limited, and some traders lowered prices to sell and facilitate deals. Transactions in the cobalt sulphate, cobalt chloride, and Co3O4 markets remained sluggish. Downstream wait-and-see sentiment was strong, and restocking demand had not yet materialized. Cobalt powder prices continued to edge lower, and off-season pressure on hard alloys persisted. Overall, cobalt chain prices may mainly consolidate in the short term, and subsequent recovery will likely need to wait for a rebound in cobalt salt valuations and improvement in downstream demand.

Ronbay Technology Expects H1 Return to Profit as LMFP Reaches Full Production and Sodium-Ion Cathodes Scale Up

Ronbay Technology expects net profit attributable to shareholders of RMB 1.0-1.2 billion for the first half of 2026, compared with a loss a year earlier. The company said earnings recovered on the back of stronger demand in the new energy sector. During the period, its ternary cathode business improved profitability with higher overseas shipments, while its LMFP cathode business reached full production and sales. Its sodium-ion cathode materials also entered the stage of large-scale commercial shipments.

[SMM Analysis] Sodium-ion battery booms in June; navigate reshaping competitive landscape in H2

In June, the sodium-ion battery industry chain saw broad-based improvements. The electrolyte and cell segments, which posted the most notable increases during this cycle, exhibited typical features of “volume growth amid persistent bottlenecks”—electrolyte capacity relied on conversion from lithium battery production, and core raw material shortages began to emerge, while the cell segment recorded nearly twofold YoY growth driven by dual boosts from energy storage and two-wheelers.
