Core Viewpoint - The article highlights SAIC Motor's strategic advancements in battery technology, particularly the introduction of the MG4 model featuring a semi-solid state battery, which marks a significant step towards achieving their solid-state battery goals. Group 1: MG4 Model and Battery Technology - The MG4 will be the first globally to mass-produce a semi-solid state battery, set to debut on August 5 with a starting price of under 90,000 yuan [1] - The new MG4 is equipped with a 70kWh semi-solid state battery developed in collaboration with Qingtao New Energy, containing only 5% liquid electrolyte, which is close to solid-state battery levels [1] - The energy density of the battery reaches 180Wh/kg, with a CLTC range of 537 kilometers, and a 13.8% improvement in low-temperature performance compared to traditional lithium iron phosphate batteries [1] Group 2: Three-Step Solid-State Battery Strategy - SAIC's strategy consists of three phases: 1. The first phase involves semi-solid products with a liquid content of 10% and energy density exceeding 300Wh/kg [2] 2. The second phase aims for quasi-solid products with 5% liquid content, utilizing new dry electrode technology and high-voltage cathode materials [2] 3. The final phase targets all-solid-state products with 0% liquid content, achieving a density exceeding 98% [2] - The first step was marked by the launch of the "first-generation light-year solid-state battery" in April 2024, which will be used in the Zhiji L6 model [2] Group 3: Future Projections - SAIC's President indicated that the first all-solid-state battery, named "Guangqi Battery," is expected to be launched by 2027, with a possibility of earlier production in 2026 [3] - The next generation of solid-state batteries is projected to have an energy density exceeding 400Wh/kg, a volumetric energy density over 820Wg/L, and a capacity exceeding 75Ah [3]
