every AI flash, China galaxy released a research report on December 18, saying: give power equipment and new energy recommended (maintained) rating.

event: on December 17, Weilai CEO Li Bin live measured the mileage of 150kWh ultra-long battery pack. The results show that the energy consumption of 100 kilometers for the whole 1044km of Weilai ET7 is about 13kWh, the remaining power is still 3%, and the remaining CLTC mileage is expected to be 30km +.

semi-solid battery is expected to form a dimension reduction blow: the 150kWh battery pack tested this time is currently the largest capacity battery pack in the domestic passenger car field. the product was first released on NIODay in 2021 and uses a semi-solid battery solution. the battery cell energy density is as high as 360kWh/kg, and the battery pack density is 260Wh/kg (Ningde Kirin battery density is 255Wh/kg); It can still achieve thousands of kilometers in cold tide, it is sufficient to prove that the energy density and low temperature performance of semi-solid-state batteries are leading the mainstream liquid lithium-ion batteries. In addition, the safety of semi-solid-state batteries will also be comprehensively improved. The product is expected to be mass-produced in April next year and will be suitable for all Weilai models, which will significantly enhance the competitiveness of car companies.

semi-solid-state battery is the preferred transition solution: all-solid-state battery is the ideal next-generation lithium-electric technology, but the current technology still faces two major bottlenecks: 1) did not find a comprehensive performance standard solid electrolyte; 2) did not solve the solid-solid contact interface problem. And all-solid-state batteries have a great impact on the industrial chain pattern (the diaphragm link completely disappears, and the electrolyte link will also face major changes), so semi-solid-state batteries that are compatible with the current materials and industrial systems become the preferred solution. We expect large-scale commercialization of all-solid-state power batteries to be seen in 2030, while semi-solid-state batteries are expected to be mass-produced in the power market in 2024.

there are many players in the layout: according to the forum of 100 people for electric vehicles, weilai 150kWh battery pack supplier or weilan new energy, which is backed by the Chinese academy of sciences, is a leading start-up enterprise of semi-solid-state batteries in China, and similar ones are qingtao energy. The same layout of the domestic solid-state battery field is also the traditional old battery enterprises, such as Ningde era released on April 19 condensed state battery; Upstream enterprises, such as Ganfeng Lithium Industry released semi-solid state "Xinfeng" battery on September 5.

acceleration of loading verification: in addition to Weilai ET7, 2024 will usher in a wave of semi-solid-state battery loading verification tide, such as Celis (Ganfeng lithium battery), SAIC Zhiji (Qingtao energy), it is recommended to pay close attention to the actual use effect of the application end, or will continue to catalyze the lithium plate market upward.

Investment advice: solid-state battery technology innovation covers all aspects of the industry, it is recommended to track the whole industry chain layout. 1) The traditional system of positive and negative electrode materials is still applicable. The established leaders can continue to maintain their advantages through cooperation with battery enterprises. It is suggested to pay attention to Dangsheng Technology (300073.SZ), Rongbai Technology (688005.SH), Beitri (835185.BJ), Putailai (603659.SH), etc. 2) Electrolyte is the core key of solid-state batteries. The more difficult fields have new variables, and more powerful enterprises have more potential for transformation, it is suggested to pay attention to Duofluoroduo (002407.SZ), Xingyuan Material (300568.SZ), Shanghai Xieba (603200.SH), Enjie Stock (002812.SZ), etc. 3) The head enterprises with sufficient capital strength in the battery link and deep accumulation of research and development technology are expected to establish leading advantages.

Risk Warning: Risks of solid-state battery technology breakthroughs and less-than-expected industrialization progress, risks of less-than-expected marketing, and risks of rapid development of mainstream liquid lithium-ion battery technology and other alternative battery technologies that outperform solid-state batteries.
