The early use of colloidal gel electrolyte lead-acid batteries are
made from the water glass, and then directly added to the lead-acid
batteries in the dry state. Although it reached a "fixed" or reduction
of electrolyte mist precipitation purposes, but the capacity of the
battery electrolyte using free time than the original battery capacity
is about 20% lower, and therefore not accepted.
The battery works
Whether glass fiber membrane of the valve-sealed lead acid battery
(hereinafter referred to AGM sealed lead-acid batteries) or the use of
colloidal electrolytes valve regulated sealed lead acid battery
(hereinafter referred to as gel sealed lead-acid batteries), they are
absorbed principle to make use of the cathode battery can be sealed.
Battery charging, the cathode will be precipitated oxygen, hydrogen
anode will precipitate. Positive Analysis of positive charge in the
amount of oxygen is 70% of starts.
Release of oxygen to the negative,PA3395U-1BRS with negative reaction from the following to achieve the purpose of absorbing the cathode.
2Pb 10 O2 = 2PbO
2PbO 10 2H2SO4: 2PbS04 +2 H20
Negative hydrogen will have to charge to 90% in the beginning,
together with oxygen in the anode and cathode on the reduction
overpotential of hydrogen itself, thereby avoiding a large number of
hydrogen evolution reaction.
In terms of the AGM sealed lead-acid battery, AGM battery separator
Although the majority of the electrolyte to maintain, but 10% must not
enter the electrolyte membrane pores. Cathode oxygen is generated
through this part of the pore to the negative absorption was negative.
On the gel sealed lead-acid battery, the battery inside the silicone gel is
