Description

technical field [0001] The invention relates to the technical field of battery energy storage, in particular to a flexible battery and a method for preparing the flexible battery. Background technique [0002] Currently widely used batteries include dry batteries and accumulators, among which common dry batteries are the most used, and these batteries contain mercury and lead, which are harmful to the human body and the environment during production. Waste batteries are discarded without any treatment, which is harmful to environmental protection. It is quite harmful. At the same time, the battery is large in size and inconvenient to carry. It is not suitable for microelectronic products. Moreover, the existing batteries generally adopt columnar, button or square structures, which are all rigid and inflexible shapes, and are not suitable for flexible products. In response to the above problems, a flexible battery has appeared, which can be used in smart cards, music greeting...
