SEVB Unveils "Xin Na Qing" Sodium-Ion Battery Solution & AI Strategy on Tech Day

Published: Apr 21, 2026 16:44
On April 16, SEVB held its inaugural Technology Day, officially launching the **"Xin Na Qing" sodium-ion battery full-scenario solution**, covering two core fields—vehicle power and power grid energy storage—while simultaneously unveiling its AI + battery strategy. The event featured the release of a 388Ah large-capacity sodium-ion battery cell dedicated to energy storage, with a cycle life exceeding 20,000 cycles (70% capacity retention), a low-temperature discharge capacity retention rate exceeding 85% at -40°C, and room-temperature energy efficiency 7% higher than LFP batteries. A 54Ah high-C-rate sodium-ion battery cell supporting 12C discharge was also introduced, suitable for large power frequency regulation scenarios. In the vehicle sector, a low-temperature power sodium-ion battery cell was launched, featuring an energy density of 180Wh/kg and usable capacity exceeding 80% at -40°C.

SMM Cobalt Morning Briefing: This week, the cobalt industry chain continued to be in the doldrums. Refined cobalt prices were lowered to 360,000 yuan/mt, with off-season demand sluggish; for cobalt intermediate products, the price spread between upstream and downstream diverged noticeably, hindering deal progress. In the cobalt salt and Co3O4 markets, inquiries and order signing were limited, and prices mainly moved sideways. Cobalt powder transaction prices remained at 455,000 yuan/mt, but demand was cautious, and there was still short-term pressure to test the bottom. Orders for ternary cathode precursors and ternary cathode materials were relatively stable; LCO prices were lowered due to falling raw material costs; and the market focused on the pace of restocking in Q3.

[SMM Cobalt & Lithium Morning Brief: Battery Material Prices Show Divergent Trends, End-user Procurement Remains Cautious] Lithium ore prices are in the doldrums but low-priced resources are limited, lithium carbonate spot and futures prices rebounded, and lithium hydroxide maintained a steady slight increase. Refined cobalt and cobalt salt are generally in the doldrums, impacted by off-season demand, sufficient inventory, and cautious procurement. Nickel sulphate cost support strengthened, ternary cathode precursor prices held steady, and ternary cathode material rebounded slightly, but actual cargo pick-up remained cautious. LFP prices declined along with raw material, while shipments continued to grow, supported by energy storage and commercial vehicle demand. Anode, separator, and electrolyte prices were generally stable, with expectations for some raw material cost transmission downstream. Sodium-ion battery material supply remained relatively tight, while the recycling market consolidated on a weak note due to fluctuations in lithium and cobalt raw material prices.
