InfoLink's July 29 assessment attributed RMB 0.010/Wh concessions on 280/314 Ah LFP ESS cells to a named condition: easing upstream cost pressure. SMM's August 14 lithium carbonate at RMB 151,500/MT — up roughly RMB 8,000–11,000/MT from the range prevailing when those concessions were offered — is eroding that condition. Cells shipping today still embed lower-cost material. But the supplier can point to the same SMM screen the buyer watches and withdraw the discount before higher-cost cathode reaches the line. Hunan Yuneng already did this at the CAM layer: a processing-fee increase effective August 1, citing input costs that hadn't yet flowed through every unit leaving the facility. If you're negotiating Q4 ESS cell commitments, the relevant signal is the screen price trajectory, not the lagging cost basis in current inventory.
Late June–July Lithium carbonate ~RMB 140,000–144,000/MT. InfoLink names easing cost pressure as enabling ESS cell discounts.
July 16 Hunan Yuneng announces RMB 2,000/MT CAM processing-fee increase effective Aug 1, citing iron phosphate up ~50% YTD. (SMM)
July 29 InfoLink records RMB 0.010/Wh concessions on 280/314 Ah LFP cells. Notes room for further decline "relatively limited."
Aug 14 SMM lithium carbonate at RMB 151,500/MT, +RMB 4,000/MT on the session.
Watch for Whether SMM holds above ~RMB 148,000/MT through InfoLink's next assessment (expected ~Aug 19). Sustained levels above the concession-enabling range give suppliers screen evidence to reopen quotes.
