充电宝事故,扯下了电池技术的“遮羞布”
Hu Xiu· 2025-07-08 09:19
Core Viewpoint - The mobile power bank industry is facing a significant crisis due to safety issues, particularly related to the Romoss brand, which has led to product recalls and heightened consumer anxiety regarding battery safety and performance [2][3][15]. Industry Overview - The mobile power bank market is experiencing turmoil following safety incidents, with over 1.2 million units recalled due to safety concerns [2][15]. - The global mobile power market is estimated to be around $3.005 billion in 2023, with a projected compound annual growth rate (CAGR) of only 1.3% until 2030, indicating a market nearing saturation [18]. Consumer Behavior - Over 70% of smartphone users prefer to charge their devices when battery levels drop to 10%-30%, reflecting a growing trend of "battery anxiety" among consumers [5][6]. - The average daily internet usage among residents has increased significantly, contributing to heightened battery anxiety as users rely more on their devices [6]. Technological Challenges - Despite advancements in smartphone technology, battery capacity has not kept pace, with the iPhone 15 only marginally improving from the iPhone 5S in terms of battery capacity [10]. - The current battery technology, particularly lithium-ion batteries, is approaching physical limits in energy density, leading to stagnation in real capacity improvements [13][22]. Price War and Its Implications - The ongoing price war in the mobile power bank sector has led to a significant drop in prices, with some products seeing reductions from around 129-149 RMB in 2021 to as low as 69 RMB by 2024 [15][16]. - This price competition has pressured manufacturers to cut costs, which has resulted in safety compromises, as seen in the recent safety incidents linked to substandard battery components [17][21]. Future Outlook - The industry must shift focus from price competition to technological innovation to address the growing demand for battery capacity and safety [22]. - The historical context of battery development suggests that significant breakthroughs may take decades, raising concerns about the industry's ability to meet future demands [22].

一份“后罗马仕”时代的充电宝/手机保养指南
Hu Xiu· 2025-07-08 05:20
上一次买新的充电宝,是哪年的事情了? 如果是两年前,那你可得多留意了。 最近两周,充电宝的话题闹得沸沸扬扬,从机场到地铁的神经都紧张了起来,仿佛大家口袋中的不确定性因素一夜之间突然变多了一样。 在阅读这篇文章之前,请先问自己一个问题: 虽然"充电宝"本身的问题已经暂时告一段落,几家涉事的企业各自提出了解决方案,被曝出问题的供应链后续需要怎样的处理和整顿还有待观望,但我们 更需要关注事件背后一个更广泛的问题: 充电宝的寿命不是无限的——我们身边所有的锂电池产品,都是消耗品。 充电宝是有保质期的 本轮大规模充电宝质量问题的罪魁祸首,就是充电宝零件供应链上的一家电芯代工厂。根据报道,这家代工厂在某批次的生产中违规替换了电芯正负极之 间的隔膜材料,导致隔膜质量不合格。 使用这批问题电芯的充电宝产品于2024年初前后进入市场,并由于不合格的隔膜导致充电宝过热、鼓包、乃至喷烟起火等一系列后续问题,最终引发了近 期一切有关于充电宝的召回、禁运等社会事件。 正如原理图所展示的,"隔膜"是每一块锂离子电池内部都不可或缺的材料:它们不仅要在强腐蚀性的电解液中保持自身的物理和电化学性质稳定,更是要 在轻薄和抗穿刺抗拉伸性能之间实现 ...
