With the simple setup, one can gain more command over the electrolysis reaction by removing a battery at different intervals. This reduces the voltage and increases the actual production time. As low as 1.5 volts can be used. Keep in mind, however, that the generation time is increased as the voltage is lowered.

We also noted that the voltage fluctuations of our battery were larger than those in the literature because of the smaller size and the lack of an ion-exchange polymer coating . A picoliter battery is expected to have a larger fluctuation than a macroscopic one, because the inhomogeneity of the electrode material plays a larger role on a smaller area. However, the

Thanks to the designable structure of CONs, we believe that the colloid electrolyte featuring a multiscale structure paves a way to develop electrolytes for lithium metal batteries (LMBs) and other alkali-ion/metal batteries. Current electrolytes often struggle to meet the demands of rechargeable batteries under various working conditions.
During the battery cycle process, factors such as the electric field effect and its constantly changing direction, ion concentration’s variations at the interface, and bulk phase of electrolyte can significantly influence both the stable state and motion behavior of colloidal particles.
