[SMM Analysis] This week, the energy storage battery cell market remained stable overall. The pullback in lithium chemical prices has not yet significantly transmitted to the battery cell side, and only some orders adopting a raw material linkage mechanism saw slight downward adjustments. The average price of 314 Ah battery cells remained around 0.365 Yuan/Wh. As the implementation details of the battery consumption tax have not yet been released, most battery cell enterprises have not yet uniformly raised prices. The additional tax costs may be shared through negotiation between upstream and downstream players in the industry chain. In terms of product structure, in H1, shipments of large-capacity battery cells above 500 Ah reached approximately 42 GWh, accounting for 8.6%. The market is still dominated by deliveries of 314 Ah products. As large battery cell capacity is gradually released in H2, the shipment share of these cells is expected to increase to around 15%.

The energy storage battery cell market overall stayed stable this week, with no significant fluctuations on either the supply or demand side. Although lithium chemical prices have pulled back recently, the cost decline has not yet been clearly transmitted to battery cells due to factors such as raw material procurement cycles, order pricing mechanisms, and enterprise profit margins. Only a small portion of orders using raw material price linkage mechanisms saw slight decreases, and overall transaction prices remained stable. Currently, the average price of 314Ah energy storage battery cells is maintained at around 0.365 Yuan/Wh, remaining the mainstream delivered product in the utility-scale energy storage market.

Regarding the battery consumption tax, as the specific collection and implementation details have not yet been announced, most battery cell enterprises have not uniformly raised prices for downstream clients. Only some new orders have reserved room for tax adjustments in advance in their quotations and contract terms, and the market has not yet formed a consistent price increase trend. It is expected that once the rules are clarified, the additional tax costs may be shared by upstream and downstream players along the industry chain through negotiations among battery cell enterprises, system integrators, and end-user clients. The actual extent of transmission will still depend on enterprise order structures, client bargaining power, and their own capacity to absorb costs.

Product structure, in H1 2026, shipments of high-capacity energy storage battery cells above 500Ah were approximately 42 GWh, accounting for 8.6% of total energy storage battery cell shipments. Current utility-scale energy storage projects still mainly use 314Ah products. With high-capacity battery cell production lines gradually coming online and entering the ramp-up stage in H2, the delivery scale for products above 500Ah is expected to increase further, and its shipment share is estimated to rise to around 15% in H2. However, considering that production line ramp-ups, client verification, and project introductions all require a certain period, the increased capacity of large battery cells may not fully translate into actual shipments in the short term. Overall, energy storage battery cell prices are expected to remain stable with minor adjustments in the short term. Future focus should be on the consumption tax details, cost transmission methods, and the actual delivery progress of high-capacity battery cells.

The cobalt powder market remained weak this week, and actual transactions stayed thin. On the supply side, mainstream producers kept their offers within RMB 440,000‑460,000 per tonne, while some physical deal prices have dipped to RMB 430,000‑440,000 per tonne. More low‑price offers emerged among traders, further depressing market psychological price levels. Cobalt carbonate, the raw material, remained under price pressure. Some offers have fallen below RMB 200,000 per tonne. Market trading nearly stalled with no valid transaction references available. Downstream cemented carbide enterprises are constrained by end‑user orders, showing no acceleration in raw‑material consumption and maintaining slow purchasing rhythms. Apart from long‑term contract orders, spot‑deal volumes are relatively limited. In terms of market sentiment, most participants adopt a wait‑and‑see stance, generally believing that no notable market improvement will materialize in the short term.
