The production line of a super capacitor is a complex production line, and so many factors need to be considered during the designing process.
A bioelectrochemical system (BES) can be operated in both "microbial fuel cell" (MFC) and "microbial electrolysis cell" (MEC) modes, in which power is delivered and invested respectively. To enhance the electric current production, a BES was operated in MFC mode first and a capacitor was used to collect power from the system. Then the charged capacitor …
The capacitors were then checked for leaks. If a capacitor failed the leak test, it was removed from the assembly line and sent to salvage and repair. Salvage and repair of large capacitors that did not meet test specifications involved drilling to drain the PCB, removing the cover seal, and manually removing and repairing the wet components.
