During outdoor activities like hiking, camping, and fieldwork, convenient access to power is crucial. Traditional charging methods, such as carrying power banks, require pre-charging and have limited capacity, while suitable charging facilities are often difficult to find outdoors. Flexible perovskite battery-powered backpacks, however, effectively utilize solar energy, providing convenient charging for devices in outdoor and mobile environments.

[0003] Traditional solar-powered backpacks typically use relatively rigid solar panels mounted in specific locations on the backpack, connected to a built-in energy storage battery via simple wiring. When sunlight shines on the solar panel, based on the photoelectric effect, the panel converts solar energy into electrical energy, which is stored in the energy storage battery. Users can then charge external devices via a charging port connected to the energy storage battery.

[0004] However, traditional solar-powered backpacks suffer from inconvenient cable storage and are prone to dust and dirt accumulation. In practical use, charging cables are often placed haphazardly inside or attached to the backpack, making them inconvenient to access and susceptible to dust, mud, and other impurities in complex outdoor environments, affecting their lifespan and charging performance. To address these issues, a backpack incorporating a flexible perovskite battery for integrated charging and discharging is proposed. Utility Model Content
