Solid-state batteries were a hot topic at the 2026 Two Sessions, where delegates noted that the industry is at a critical inflection point, moving from “samples” to “products.”

Ouyang Minggao pointed out that large-scale mass production of all-solid-state batteries will still require 3–5 years, with test vehicles expected to appear by the end of 2026. Sulphide electrolyte has fallen from 20 million/mt to the million-level range. However, he stressed that the technical difficulty is extremely high and advised consumers that they “need not wait,” as LFP batteries remain the “ballast stone” at present.

[Spot Silicon Metal Prices Probe Higher as Market Transactions Remain Stagnant; Polysilicon Price Trend Declines]: On the supply side, production release from silicon metal capacity that resumed production in early March increased total silicon metal supply compared with early March. Recently, there have been scattered production resumptions in Southwest China, but these have not yet become widespread, so their impact on supply growth has been very limited. On the cost side, spot prices of silicon coal and electrodes have remained temporarily stable recently, while petroleum coke prices rose slightly. Coupled with higher gasoline prices, road transport freight rates were raised slightly, providing relatively strong cost support for silicon metal. On the demand side, performance has mainly remained stable recently. During the week, spot silicon metal transactions were stagnant, inventory in the intermediate segment stayed at a high level, and downstream demand was weak, so silicon metal prices had limited room to rise or fall and were mainly range-bound in consolidation.

The University of Tsukuba in Japan successfully developed a new-type magnesium-air solid-state battery, using a nitrogen-doped porous graphene cathode to solve the problem of chloride corrosion, providing a high-safety, low-cost technological pathway for flexible electronics and wearable devices. At the same time, the Record Ridge magnesium mine project in British Columbia, Canada, has triggered strong opposition from the local tourism community over plans to transport ore to China for processing, and has been halted by litigation, with a court hearing scheduled for March 10. The two developments respectively highlight magnesium’s cutting-edge applications in new energy technology and the real-world tensions in resource development.

The market price of silicon electrodes edged down during the year. Currently, the types of electrodes used by downstream industrial silicon manufacturers are also different according to their production and smelting habits.

SHANGHAI, May 19 (SMM) – Electrode prices temporarily stabilised this week as raw material prices stopped falling.
