Mawei Shares Co., Ltd. recently signed a strategic cooperation framework agreement with Anhui Hueshen New Energy Technology Co., Ltd., under which Hueshen New Energy will release orders for no less than 20GW high-efficiency heterojunction solar NBB (None Busbar, Chinese name "No Main Grid") component soldering equipment to Mawei Shares Co., Ltd. in three years. The first 5.4GW NBB soldering equipment procurement contract was signed on September 16. Both parties will jointly promote technological innovation and cost reduction and efficiency improvement of heterojunction products, and promote HJT+NBB to become the new mainstream technology of photovoltaic. In order to further reduce the silver paste consumption of heterojunction cells and components, Mawei Shares Co., Ltd. has developed the second generation of No Main Grid technology NBB and its soldering equipment, which can reduce the silver paste consumption by more than 30% by eliminating all the main grids of the cells.

SMM Daily Review: Lithium Carbonate Spot Prices Drifted Lower on September 2
Today, SMM battery-grade lithium carbonate spot prices drifted lower compared with the previous trading day. The lithium carbonate 2701 contract opened lower at 157,000 yuan/mt today, then fluctuated downward after the open. In the morning session, it traded weakly around the 156,000-157,000 yuan range, with an intraday high of 157,800 yuan/mt. Near midday, it quickly dropped to 153,200 yuan/mt, hitting a new intraday low. Around midday, prices seesawed repeatedly in the 154,000-156,000 yuan range. In the afternoon, bulls briefly pushed prices up but failed to break above the average price line. Prices weakened again in late trading, eventually closing down 3.2% at 154,800 yuan/mt, with open interest falling by 9,123 lots. In the spot market, downstream buyers purchased on dips as needed. At 155,000 yuan/mt and below, downstream spot order purchase willingness continued to recover. On the supply side, as prices drifted lower, willingness to sell spot orders remained weak, with some lithium chemical plants holding prices firm and holding back from selling. Overall, market inquiries and actual transactions were relatively active.

Battery-Grade Lithium Sulfide: Will Q4 See a Spike?
Key takeaway upfront: A Q4 spike is unlikely, but we do expect continued moderate growth. Monthly output is likely to settle in the 9–10 tonne range – a modest step-up from Q3, not an explosive leap.
