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 ...

Core Viewpoint - The notion that electric vehicle batteries must be discarded after eight years is a misunderstanding, as battery lifespan is influenced by various factors including usage patterns and environmental conditions [7][12]. Group 1: Warranty and Battery Lifespan - Different brands have varying warranty periods for electric vehicles, with some offering lifetime warranties for key components like batteries [2][5]. - The mandatory warranty for batteries is at least 8 years or 120,000 kilometers, but this does not guarantee that the battery will fail after this period [5][7]. - Battery performance typically declines over time, affecting the overall driving experience, and replacement costs can be significant [4][6]. Group 2: Factors Affecting Battery Life - Battery lifespan is determined by multiple factors, including charge cycles, calendar life, and environmental conditions [7][8]. - Current lithium-ion batteries can last approximately 10 to 20 years under normal usage conditions, with three types of lithium batteries having different cycle counts [7][8]. - Poor usage habits, such as frequent overcharging or exposure to extreme temperatures, can accelerate battery degradation [8][12]. Group 3: Second-Hand Market Impact - The condition of the battery significantly affects the resale value of electric vehicles, with older models often valued at only 20% of their original price due to battery performance decline [9]. - Early electric vehicle models may exhibit more pronounced battery degradation, leading to cautious evaluations by second-hand dealers [9]. Group 4: Battery Replacement Indicators - Signs that a battery may need replacement include rapid loss of charge, inability to reach full capacity, and significant reductions in driving range [10][11]. - Regular health checks and monitoring of battery performance are recommended to ensure longevity and performance [11]. Group 5: Best Practices for Battery Maintenance - Maintaining battery charge between 20% and 80% and minimizing fast charging can extend battery life [11][12]. - Temperature management is crucial, with recommendations for insulation in cold climates and avoiding immediate charging after exposure to heat [12].
