With the rapid advancement of technology, batteries, as an indispensable “source of energy” in our daily lives, provide power support for various devices. However, seemingly ordinary batteries gradually “age” during operation, ultimately affecting the normal use of devices. So, why do batteries “age”, and how can we help them “extend their lifespan”? This paper adopts a unique anthropomorphic perspective to delve into the “inner world” of batteries. It first unveils the mystery behind battery operation, explaining how they convert chemical energy into electrical energy. In this process, key factors such as resistance, conductivity, and ion mobility act as “behind-the-scenes drivers”, influencing battery performance. To help batteries “delay aging”, the paper explores practical methods to extend their lifespan, enabling batteries to maintain “youthful vitality” and deliver better performance. Finally, it introduces future development trends of new high-energy-density batteries, such as all-solid-state batteries and lithium-air batteries. These emerging technologies not only hold the potential to address the “aging” issues of traditional batteries but also contribute to environmental protection efforts.
