Folding. When rocks deform by plastic deformation they can bend and fold. The process of folding occurs when rock is compressed, as it is along colliding plate boundaries. Upturned folds are called anticlines and down turned folds are called synclines . Anticlines and synclines are geologic structures, that is, they are folds in rock material. They give expression to the surface as linear

The as-constructed battery has an energy density of 275 WhL−1, which is 96.4% compared with a conventional cell. In addition, even after different mechanical deformations at 0.5 C for 100 cycles, the foldable battery can still remain 96% with an average Coulombic efficiency higher than 99.9%.
Despite the huge potential of mechanically flexible batteries in healthcare, robotics, transportation and sensing, their development towards real-world applications is stalled due to issues such as capacity decay, limited energy/power density at any given pliability, compromised safety and poor packaging.
The zigzag-like battery can be well fitted to many opera- tion scenarios. The as-constructed battery has an energy density of 275 WhL−1, which is 96.4% compared with a conventional cell.
However, for ultra-FBs, newer techniques such as electrospinning and micropatterning need to be established within the battery industry. Similarly, nanocarbon additives such as CNTs/graphene and electrolytes including ILs and solid electrolytes should be optimised for large scale integration.
To quantify dynamic stability, each step of mechanical characterisation (bending, twisting and their speed, etc.) should be conducted in operando (charge/discharge, cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), etc.)
