The Zhitong Finance App learned that China Post Securities released a research report saying that on March 25, Zhiji Auto announced that its new model Zhiji L6 will use a quasi-900V ultra-fast charging solid-state battery, focusing on the three characteristics of battery life, fast charging, and safety. Semi-solid batteries will be launched one after another in 2024. In December '23, NIO's 150kwh semi-solid state battery road tested a battery life of 1044km; SAIC Motor will mass-produce semi-solid state batteries for different models starting in 2024. The bank indicated continuous breakthroughs in the industrial technology process, and recommended focusing on investment opportunities related to the fast charging and solid-state battery industry chain. Battery side: Ningde Era (300750.SZ), etc.; Material side: Putailai (603659.SH), Zhongke Electric (300035.SZ), Dangsheng Technology (300073.SZ), Enjie Co., Ltd. (002812.SZ), etc.

The views of China Post Securities are as follows:

The Zhiji L6 will be equipped with a quasi-900V ultra-fast charging semi-solid state battery.

On March 25, Zhiji Auto announced that its new model, the Zhiji L6, will use a quasi-900V ultra-fast charging solid-state battery, focusing on the three characteristics of battery life, fast charging, and safety. In terms of material systems, the cathode uses ultra-high nickel, the anode uses a silicon-carbon doping scheme, and the electrolyte uses a solid electrolyte. In terms of performance, it supports a battery range of 1000 km+, safety protection without heat spread and fire, and supports 900V high voltage fast charging for charging.

Fast charging+semi-solid state, battery technology continues to be interpreted.

The industrialization of solid-state batteries at home and abroad is accelerating. Overseas situation: American companies are intensively starting tests; Japanese and Korean companies target mass production in 2028; Solid Power delivered the A model for BMW certification in November 23; Factorial Energy delivered A maintenance to battery manufacturers for testing in October 23; Toyota plans to load all-solid-state batteries in 2027; SKI plans to commercialize solid-state batteries in 2028. Domestic situation: Semi-solid state batteries will be launched one after another in 2024. In December '23, NIO's 150kwh semi-solid-state battery road tested 1044km battery life; SAIC Motor will mass-produce semi-solid state batteries for different models starting in 2024. In terms of fast charging, many new cars, such as the Xiaopeng G6, Zhiji LS6, Ideal MEGA, Zhijie S7, and Wangjie M9, have begun to support 800V fast charging. Also, judging from the car pricing situation, fast charging has already fallen into the price range of 200,000 to 300,000 yuan. The bank believes that the penetration rate of fast charging in new energy vehicles will begin to increase rapidly.

Changes in the material system: Judging from the opportunities in the industrial chain, the changes in solid-state batteries are mainly due to the electrolyte switching from a liquid form to a solid electrolyte; the cathode will use materials with higher energy density, such as ultra-high nickel; the anode will be mixed with a silicon anode. The main change in fast charging is the anode material, which improves material properties through further modification and carbon coating.

Risk warning: downstream demand falls short of expectations; risk of changes in technology routes; market competition increases risk.
