The colloidal lead-acid battery is an improvement of the ordinary lead-acid battery with liquid electrolyte. The sulfuric acid electrolyte is replaced by the colloidal electrolyte, which is improved compared with ordinary batteries in terms of safety, storage capacity, discharge performance and service life.

The colloidal lead-acid battery uses a gel-like electrolyte, and there is no free liquid inside. Under the same volume, the electrolyte has a large capacity, a large heat capacity, and a strong heat dissipation ability, which can avoid the thermal runaway phenomenon that is easy to occur in general batteries; the electrolyte concentration is low. The corrosion effect is weak; the concentration is uniform, and there is no electrolyte stratification.
