Zhong Guo Qi Che Bao Wang·2025-06-09 01:31Core Viewpoint - Solid-state batteries are a hot topic in the electric vehicle industry, but their commercialization faces significant challenges despite recent advancements by leading battery companies [2][6]. Group 1: Industry Trends - Leading battery companies are adopting a dual strategy of developing both solid-state and semi-solid-state batteries to accelerate technological breakthroughs and market positioning [3][6]. - CATL has launched a semi-solid-state battery with an energy density of 500Wh/kg and plans to achieve small-scale production of solid-state batteries by 2027 [3][4]. - BYD has been developing solid-state batteries since 2016, with plans to launch a 60Ah solid-state battery in 2024 and achieve mass production by 2030 [4][5]. - Guoxuan High-Tech has completed its first solid-state battery production line with a design capacity of 0.2GWh and a yield rate of 90% [4][5]. Group 2: Technical Challenges - The transition from laboratory samples to mass production of solid-state batteries is expected to take 8 to 10 years, with many current offerings being semi-solid or quasi-solid-state batteries [6][7]. - The industry lacks a clear and suitable production technology for solid-state batteries, with various technical routes each having distinct advantages and disadvantages [6][7]. - High production costs and low yield rates hinder the large-scale adoption of solid-state batteries, with significant modifications required for existing production lines [7][8]. Group 3: Market Outlook - Semi-solid-state batteries are projected to have a stronger commercial viability in the short term, with expectations that they will dominate the market in the next five years [8][9]. - The energy density of semi-solid-state batteries ranges from 350 to 450Wh/kg, supporting rapid charging and stable performance across a wide temperature range [8][9]. - Several automakers have already begun mass production of semi-solid-state batteries, indicating a growing acceptance and integration of this technology in the market [9][10]. Group 4: Strategic Implications - The dual approach of advancing semi-solid-state batteries while continuing to invest in solid-state technology is seen as a strategic advantage for companies in the industry [10][12]. - Solid-state batteries are viewed as a potential game-changer for the electric vehicle market, but their development is still in the early stages, requiring time for the industry to mature [11][12].
