The global energy transition has entered the “deep-water zone.” Nickel, cobalt, and lithium have long ceased to be simple “cyclical commodities”; they are now core bargaining chips in national energy security and industrial competition. Supply side, resource nationalism is “tightening the chokehold.”
Major resource countries have collectively tightened export and development policies, signaling the end of the era of low-cost expansion. The current landscape is this: even the slightest policy shift in any country can trigger “stormy waves” across global markets. Demand side, new energy vehicles and energy storage—the “dual engines”—continue to surge.
On one side is explosive growth in rigid demand; on the other, supply elasticity is increasingly constrained by the combined pressures of policy, environmental protection, and geopolitics. The supply-demand mismatch is rapidly widening, and industry value is being forcibly repriced. The key to breaking the deadlock lies in technological variables.
The 2026 SMM Lithium Battery Raw Materials Conference, hosted by Shanghai Metals Market (SMM), Shijiazhuang Dingwei Chemical Equipment Engineering Co., Ltd. will attend in grand style as a sponsor, and will invite core global players to gather in Chengdu to focus on just three things: decoding the shifting landscape, connecting resources, and finding a certain path to growth.
We sincerely invite your participation! Click to register for the conference now—see you in Chengdu.
