A-shares surge as lithium battery sector rallies on storage demand and supply shocks

The lithium battery sub-index on China's A-share market jumped nearly 3% intraday on March 27, with more than a dozen stocks—including Rongjie Co., Ltd. (融捷股份), Ganfeng Lithium (赣锋锂业), Yongshan Lithium (永杉锂业), Shengxin Lithium Energy (盛新锂能) and CATL (宁德时代)—hitting their daily limits. The jump reflects more than a short squeeze. Investors are pricing in a dual dynamic: accelerating demand driven by grid-scale energy storage and simultaneous supply uncertainty that could flip a mild global surplus into a shortage. Is this a cyclical rebound or a structural reversal?

Demand pivot to storage, and policy that underwrites returns

Data compiled by industry groups show a marked pivot in 2025 demand from vehicle traction batteries toward stationary storage. According to high-tech consultancy GGII, China’s lithium battery shipments rose to 1,175 GWh in 2024 (+32.6%), split between 780 GWh for EVs and 335 GWh for storage (+23% and +64% year‑on‑year respectively). Projections for 2025 put China at about 1,875 GWh (+53%), with storage output surging to roughly 630 GWh (+85%) and Q4 2025 storage shipments reportedly up more than 20% quarter‑on‑quarter. Add to that Beijing’s new capacity‑price mechanism for generation side storage (the so‑called “114 document”), which it has been reported that will pay a “base salary” to eligible storage assets simply for standing ready — materially improving project IRRs and spurring new builds.

Supply risks: Zimbabwe ban, Australian operations under pressure

On the supply side, the picture looks fragile. It has been reported that Zimbabwe’s Ministry of Mines abruptly suspended all exports of lithium ore and concentrates in late February, a move that reportedly covers in‑transit shipments and has no clear end date. SMM data cited in the market note show Zimbabwe and Australia together supplied roughly 82% of China’s spodumene imports in 2025 (63% Australia, 19% Zimbabwe). Separately, Bloomberg and Australian outlets have reported diesel shortages in Australia—attributed in part to disruptions tied to heightened Middle East tensions—that are already constraining mining operations. If diesel‑driven throughput cuts in Australia combine with Zimbabwe’s export ban, analysts warn the previously small global surplus (about 40,000 tonnes, ~2% in 2025, per one research house) could rapidly turn into a noticeable shortfall.

The market must now answer the central question: will improved economics for storage plus episodic supply shocks produce a sustained structural rebalancing, or merely a one‑off cyclical uptick? For investors and policymakers alike, the outcome will hinge less on China’s domestic policy than on geopolitical drivers—Middle East instability and producer‑country export controls—that are outside Beijing’s immediate control.
