技术领域technical field
本发明涉及锂电池技术领域，尤其涉及一种柔软性高的柔性电池。The invention relates to the technical field of lithium batteries, in particular to a flexible battery with high flexibility.
背景技术Background technique
随着科学技术的发展，智能手机和可穿戴电子设备的厚度越做越薄，对为这些电子设备供电的电池的要求也越来越高。目前，锂电池的电芯构成一般是由涂覆有正极活性材料的正极片、涂覆有负极活性材料的负极片和隔离正负极的隔膜卷绕而成，而由于正极片和负极片相对于隔膜硬很多，正极活性材料和负极活性材料分别涂覆到正极片和负极片后，无形中增加了正极片和负极片的厚度和硬度，导致电芯不易卷绕成型，同时也增加卷绕厚度，不利于降低电池整体厚度或硬度，导致电池不能做成可弯曲的柔性电池，不适于在可穿戴的电子设备中使用；而且，当正极片或负极片卷曲时，涂覆的正极料或负极材料容易被打破脱落的情况，导致生产的电池导电性变差，造成电池报废，提高生产成本。With the development of science and technology, the thickness of smartphones and wearable electronic devices is getting thinner and thinner, and the requirements for batteries that power these electronic devices are also getting higher and higher. At present, the battery cell of a lithium battery is generally composed of a positive electrode sheet coated with a positive electrode active material, a negative electrode sheet coated with a negative electrode active material, and a separator separating the positive and negative electrodes. Because the separator is much harder, after the positive active material and the negative active material are coated on the positive and negative plates respectively, the thickness and hardness of the positive and negative plates are virtually increased, making it difficult for the battery core to be wound and formed, and it also increases the winding capacity. Thickness is not conducive to reducing the overall thickness or hardness of the battery, so that the battery cannot be made into a bendable flexible battery, which is not suitable for use in wearable electronic devices; moreover, when the positive electrode or negative electrode is curled, the coated positive electrode or The negative electrode material is easy to break and fall off, resulting in poor conductivity of the produced battery, causing the battery to be scrapped, and increasing production costs.
