Correspondingly, foldable batteries with cycling stability (1200 cycles of capacitance retention at 5.0 A obtained. Compared with the utilization of 3D precursors, the construction of 1D and 2D composites includes chemical bonding such as covalent bonding among the functional groups of 1D and 2D materials.
Metal cases are required to prevent the air and moisture penetration in battery packaging. For example, during the washing of wearable electronics, water and laundry deter-gents, which can cause severe damage to the batteries, may penetrate the batteries as existing packaging materials and technologies are ine ective in protecting the batteries.
