Colloidal lead-acid battery is an improvement of common lead-acid battery with liquid electrolyte. It uses colloidal electrolyte to replace sulphuric acid electrolyte, which is better than ordinary battery in safety, charge storage, discharge performance and service life.
Deposition was carried out at a constant voltage of 80 V for 5 min. Colloidal electrolyte contains 4.75 g dm −3 NMC (5 to 25 μm), 0.25 g dm −3 CB (100 to 300 nm) and 0.1 g dm −3 PDDA. Table 1 shows film thickness of EPD electrodes, by varying deposition parameters.
This opens a new opportunity for achieving high power/energy density electrode materials for advanced energy storage devices.
All colloidal electrolyte contains a total of 5 g dm −3 materials loading, specifically 95 wt. % active materials (4.75 g dm-3 NMC) and 5 wt. % inactive materials (0.25 g dm −3 CB). These materials were dispersed in NMP solvent firstly, followed by the addition of 0.1 g dm −3 PDDA.
Selecting a standard lifetime as one of the main parameters of the rechargeable energy storage devices is entirely subjected to the nature of the device, and it is highly linked to the operating conditions such as temperature, voltage, charge–discharge current, the depth of the discharge, and at some stages, the humidity [17, 27].
