Dear User, To further optimize the SMM ternary cathode precursor data service and better align it with market demands, we are adjusting the naming of certain monthly ternary precursor output data points. The specific changes are as follows: Additionally, to more precisely meet customer needs, we are now splitting the monthly output data for 7-series, 8-series, 9-series, and NCA ternary precursors, providing independent data for each series. The newly added and adjusted data points are as follows: Based on the above adjustments, the data points for the monthly output forecast values of ternary precursors have been simultaneously updated. The specific changes are as follows: Thank you for your continued attention and support for SMM's new energy and nickel data services. SMM Information & Technology Co., Ltd.
