Each debonding approach has its own advantages, therefore, it is challenging to conclude that electrochemical debonding is superior to other debonding techniques [39]. Anduix‐Canto et al. [40] investigated the mechanism of electrically debondable acrylic adhesives (AcA) based on imidazolium ionic liquids using a variety of spectro-microscopic techniques.
The results reveal that the well-designed pre-strain can significantly delay the debonding onset (by up to 100%) and considerably reduce the debonding size. The critical values of the pre-strain are identified, and the pre-strain design …

Fig. 2. Two potential modes of failure in a hollow silicon particle coated with a stiff shell. (a). The lithiation of the silicon particle induces tensile hoop stress in the shell, which may cause the shell to fracture. (b) The delithiation of the silicon particle induces radial tensile stress, which may cause debonding between the core and the shell. - "Fracture and debonding …

The superconducting coil''s absence of resistive losses and the low level of losses in the solid-state power conditioning contribute to the system''s efficiency. SMES offer a quick response for charge or discharge, in a way an energy battery operates. In contrast to a battery, the energy available is unaffected by the rate of discharge.
