SiC负极电池具备更高的电池密度，可在相同物理尺寸下实现更大的电池容量，同时也能支持更薄的机身设计。首款搭载SiC电池的智能手机于2023年2月 推出，其大规模普及始于2024年下半年，以荣耀X60 Pro、Redmi K80和vivo S19等畅销机型为代表。该电池在中端价位段的普及不仅加速了该技术的市场 渗透程度，并有效缓解了消费者在屏幕使用时间延长以及高耗能应用(如端侧生成式AI)普及背景下所面临的关键痛点。 2025年5月，中国主要OEM厂商的平均电池容量均实现了两位数的同比增长，这使得6000mAh及以上电池容量的智能手机市场份额从一年前的9%跃升至 35%。截至2025年5月，OnePlus凭借其中国市场专属的Ace系列位居平均电池容量首位。同样，荣耀(Play系列)、华为(畅享系列)和vivo(S系列)等品牌也在 其专供中国市场的机型中配备了更大容量电池。 | | | 数据来源： Counterpoint Research《全球手机机型销量追踪报告》，2025年5月 根据Counterpoint Research最新的《全球手机机型销量追踪报告》，2025年5月中国市场智能手机的平均电池容量达到 ...

Core Insights - The average battery capacity of smartphones in the Chinese market reached 5418mAh by May 2025, marking an 11% year-on-year increase, while the global average only grew by 3% [2][4] - The adoption of silicon-carbon (SiC) batteries has significantly contributed to this growth, with a capacity difference of over 500mAh compared to other global markets [2][4] Battery Technology and Market Trends - SiC batteries offer higher energy density, allowing for larger capacities within the same physical size, and support thinner device designs [4] - The first smartphone featuring SiC batteries was launched in February 2023, with widespread adoption beginning in the second half of 2024, represented by popular models such as Honor X60 Pro, Redmi K80, and vivo S19 [4] - By May 2025, the market share of smartphones with battery capacities of 6000mAh and above surged from 9% to 35% year-on-year, driven by major OEMs in China [4] Competitive Landscape - OnePlus leads in average battery capacity in the Chinese market with its Ace series, while brands like Honor, Huawei, and vivo also offer models with larger batteries tailored for the Chinese market [4] - Counterpoint Research anticipates that China will maintain its lead in battery capacity and may further widen the gap, as more models are launched in China before being introduced globally [5] - As OEMs increasingly promote large battery capacities as a product differentiation strategy, the gap between China and other global markets is expected to narrow over time [5]
