充电宝事故，扯下了电池技术的“遮羞布”

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].
