Abstract

This invention discloses a kind of nano-colloid dynamic batteries including positive and negative pole plates, baffles and electrolyte, a battery tank and connector terminals, in which, the pole plate and the baffle include nano-SiO2, nano-arbon and nano-stannous oxide to prevent early attenuation resulted from fluid loss and delamination of the electrolyte to reduce corrosion speed so as to increase life time and dynamical performance.

Description

Technical field [0001] The invention belongs to a lead-acid battery, in particular to a colloidal lead-acid battery. Background technique [0002] Batteries are the energy carrier of electric vehicles and a key component that affects the performance of electric vehicles. With the popularization of electric bicycles and the development of electric vehicles, higher and higher requirements are put forward for the discharge time, capacity, and stability of batteries. [0003] Lead-acid sealed batteries are composed of positive and negative plates, separators and electrolyte, battery tanks and connecting strips (or lead parts), wiring terminals and exhaust valves. [0004] A storage battery is generally composed of 3 cells (6V batteries) or 6 cells (12V batteries). Each single cell is formed by overlapping several positive plates and several negative plates (the negative plate is one more than the positive plate), separated by superfine glass fiber separators. Several positive plates ...
