英伟达市值达5.8万亿美元,创历史新高

2026年9月,麻省理工学院团队展示一种可在胃肠道环境中逐步分解的微型电池,面向需要供电的可吞服电子设备。电池使用镁和三氧化钼作为电极,并配合可吸收的凝胶电解质,输出电压达到1.84伏。研究人员制作了直径7.5毫米的圆片和长24毫米的条形版本,以适应不同装置。

在模拟胃液的酸性溶液中,电池可正常工作约三天,之后性能逐渐下降,并在数周内完全分解。团队还把它用于胃内无线识别标签,以及通过微弱电流刺激胃部的实验胶囊,验证其供电能力。研究目标是减少传统电池外壳损坏时的材料风险,并降低排出后对环境的影响。可分解设计也有利于设备保持独立运行,减少对外部供电的依赖。不过,电池材料的选择、剂量和分解速度需要与具体使用场景匹配。当前结果属于新型电源和器件研究,不能据此认为普通电池可以安全吞服,或相关装置已可直接用于临床。
