Nano-colloid power type accumulator battery

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 storage battery, in particular to a colloidal lead-acid storage battery. Background technique [0002] The storage battery is the energy carrier of the electric vehicle and a key component that affects the performance of the electric vehicle. 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 the battery. [0003] Lead-acid sealed batteries are composed of positive and negative plates, separators and electrolytes, battery tanks and connecting strips (or lead parts), terminals and exhaust valves. [0004] A battery is generally composed of 3 single cells (6V battery) or 6 single cells (12V battery). Each cell is composed of several positive plates and several negative plates (the negative plate is more than the positive plate), overlapping at intervals, and separated by ultra-fine glas...

AI Technical Summary

Problems solved by technology

[0005] The existing battery separators are mostly made of glass fiber materials, and the positive and negative plates are made of Pb and PbO 2 , the electrolyte is easy to hydrolyze and delaminate, the battery performance declines rapidly, the capacitance is small, and the number of charge and discharge cycles is insufficient, which cannot meet the current development requirements of electric bicycles
