Group 2: Phosphate Iron Lithium Battery Developments - High-density phosphate iron lithium batteries are entering mass production, with major manufacturers like CATL and BYD leading the charge [10][12]. - The introduction of fourth-generation phosphate iron lithium materials significantly enhances fast-charging capabilities and energy density, creating competitive pressure among battery manufacturers [10][12]. - The cost structure of phosphate iron lithium batteries is expected to improve due to advancements in technology and production efficiency, potentially leading to a price rebound by 2025 [31][32]. Group 3: Regulatory and Environmental Factors - A nationwide initiative to combat illegal solid waste disposal, particularly focusing on retired batteries, is being implemented, which may impact the battery recycling industry [16][18]. - New national standards for electric vehicle batteries (GB38031-2025) will take effect in July 2026, emphasizing safety and performance, which could lead to increased production costs for battery manufacturers [21][22]. Group 4: Market Trends and Sales Growth - Sales of electric vehicles are surging, with brands like Xiaomi and Leap Motor experiencing significant growth, indicating a robust demand for batteries [24][26]. - The competitive landscape is shifting as companies like BYD are adjusting pricing strategies to stabilize the market, which may alleviate some of the price pressures on battery manufacturers [27][29]. Group 5: Cost and Price Analysis of Phosphate Iron Lithium Batteries - The cost of raw materials for phosphate iron lithium batteries is stabilizing, with significant production capacity in China, which may lead to a price floor being established [31]. - The introduction of manganese-doped phosphate iron lithium batteries could enhance energy density while keeping costs manageable, further supporting market growth [32]. Group 6: Summary of Market Outlook - The lithium battery market is currently in a bottoming phase, with oversupply issues persisting despite some production cuts in South America and Africa [34][35]. - Future price increases may depend on technological advancements and regulatory changes that could reshape the competitive landscape [38][39].

Core Viewpoint - Xiaomi Auto addressed concerns regarding the potential rusting of the SU7 brake discs and battery safety standards in response to user inquiries during the rainy season [2][5][10]. Group 1: Brake Disc Concerns - Xiaomi Auto acknowledged that the recent rainy season could lead to rust on brake discs, which is a common issue for vehicles with cast iron brake discs exposed to moisture [5][8]. - The company stated that light rust typically does not affect braking performance and provided methods for users to remove rust, including passive and active rust removal functions [9]. - The passive rust removal function engages hydraulic brakes periodically under high energy recovery mode, while the active function is designed for vehicles that have been parked for extended periods [9]. Group 2: Battery Safety Standards - Xiaomi Auto confirmed that its battery safety standards exceed previous national testing standards and comply with the new national standards [10][11]. - The company emphasized its rigorous battery safety design, which includes 14 layers of physical protection and over 1,050 safety validations [12]. - In extreme conditions, such as high temperatures, Xiaomi's batteries meet the industry's strictest thermal failure safety standards, surpassing the new national requirements [12]. Group 3: Incident Context - The discussion on battery safety gained attention following a traffic accident involving a standard version of the Xiaomi SU7, raising questions about the battery supplier [13]. - The standard version of the SU7 uses batteries from CATL and BYD's Fudi Battery, while the Pro and Max versions are supplied by CATL [13]. - CATL clarified that the battery involved in the incident was not theirs, and inquiries to BYD have not received a response [14].

撰 文 / 周 洲 设 计 / 赵昊然 史上最严格的电池安全令来了。 工业和信息化部4月3日正式发布了GB 38031-2025《电动汽车用动力蓄电池安全要求》。 这一新规将于2026年7月1日起实施，被称为"史上最严电池安全令"。 与2020年版标准相比， 新国标首次将"不起火、不爆炸"从企业技术储备上升为强制性要求。 新标准增加了测试项目，包括： 一、底部撞击测试： 模拟车辆托底或飞石冲击，要求电池包在直径30毫米钢球以150焦耳能量（相 当于50km/h车速）撞击后，无泄漏、起火或爆炸，并满足绝缘电阻要求，仅离地间隙≥200mm的商 用车可豁免，乘用车全系纳入监管。 二、内部加热片触发热失控： 新增该测试方法，模拟电池内部短路等复杂故障，相较传统针刺测 试更贴近真实失效模式。同时，针刺速度从0.1-10mm/s调整为0.1-1mm/s，进一步优化测试精度。 三、快充循环后安全测试 ： 规定电池在完成300次快充循环（SOC区间20%-80%）后，需通过外部 短路测试，确保不起火、不爆炸。此举旨在防止高频快充导致的电池性能衰减和安全隐患。 新增的测试项目主要是模拟真实事故场景，要求电池系统必须具备多层级热 ...
