First, colloidal batteryThe colloid lead-acid battery is an improvement in the ordinary lead-acid battery of the liquid electrolyte, and the electrolytic solution is exchanged with a colloidal electrolyte, which is improved in terms of safety, storage capacity, discharge performance, and service life.
The colloidal lead-acid battery uses gel-like electrolytes, the internal no-free liquid, the electrolyte capacity is large, the heat capacity is large, the heat dissipation ability is strong, and the general battery can be easily generated; the electrolyte concentration is low, the plate The corrosion is weak; the concentration is uniform, there is no electrolyte layering.
working principle
The properties of the colloid lead-acid battery are superior to the valve-controlled lead-acid battery, the colloid lead-acid battery has the ability to use performance, high reliability, long service life, strong energy temperature (high, low temperature), with long discharge capabilities , Recycle discharge capacity, deep discharge and high current discharge capabilities, have advantages of overcharge and over-discharge self-protection.
The domestic colloid lead-acid battery for electric bicycles is to be fill in the AGM partition, and the silica gel and sulfuric acid solution are positive and the negative plate. The colloid lead-acid battery cannot perform an oxygen cycle in the initial stage, because the colloid is positive, the negative plate is surrounded, and the oxygen generated above the positive electrode plate cannot diffuse to the negative electrode plate, and the active material lead reduction on the negative electrode plate cannot be achieved. It can only be discharged from the exhaust valve, consistent with the rich liquid storage battery.
The colloid lead-acid battery starts dry and shrink after a period of time, producing cracks, oxygen directly to the negative electrode plate through the crack to perform an oxygen cycle. The exhaust valve will no longer be opened frequently, and the colloid lead-acid battery is close to the seal, and there is little loss. Therefore, for the main failure of electric bicycle batteries is an overwater mechanism, and a very good effect can be obtained using colloidal lead-acid batteries. The colloidal electrolyte is to solidify the sulfuric acid electrolyte in the electrolyte to gel into a gel material. Generally, the colloidal electrolyte is also added with a colloidal stabilizer and a compatibilizer, and some colloidal formulations also have a delay colloidal solidification and delay. The agent is allowed to raise the colloid.

Second, lead-acid battery
The electrode is mainly made of lead and its oxide, and the electrolyte is a battery of a sulfuric acid solution. English: Lead-Acid Battery. In the discharge state, the main component of the positive electrode is a lead, the negative electrode is main component of lead; the main components of the positive and negative electrode are leaded to the lead of sulfate. Divided into an exhaust battery and a maintenance lead-acid battery.
Performance characteristics
1, safe seal
In normal operation, the electrolyte does not disclose from the terminal or housing of the battery.
2, no free acid
The special liquid absorbing partition is maintained, and there is no free acid in the battery, so the battery can be placed in any position.
3, discharge system
After the battery has exceeds normal levels, the abbreviations of VRLA (Valve-Regulate Lead Acid Battery "valve-controlled lead-acid batteries") The battery will release excess gas and automatically resemble it to ensure that there is no excess gas in the battery.
4, easy to maintain
Due to the unique gas composite system, the generated gas is converted into water, and water does not need to be added during the use of the battery.
5, long service life
A lead-to-coride alloy fence with a corrosion structure is used, and the battery can be floated for 10-15 years.
6, the quality is stable, the reliability is high
Adopting advanced production processes and strict quality control systems, the quality of the battery is stable and reliable. Voltage, capacity and seal are performed on the line on the line.

Third, the difference between colloidal battery and lead-acid battery
The colloid lead-acid battery and the ordinary lead-acid battery are in the same performance, but only the electrolytic solution in the battery is a latex-like semi-coagulation state, one is a liquid state, the ordinary lead-acid battery in the liquid state needs to be irregular during use. The addition of distilled water maintenance, the colloid does not require additional distillate maintenance (usually the maintenance-free).
The disadvantage of colloidal lead-acid battery is that overload charge is very harmful. Once overload charging can cause non-recoverableity of the battery, even scrapped, and ordinary lead-acid battery overload caused by plate deformation and vulcanization can be small current charge and discharge Recovery (just unable to restore the original); personal feeling of clean, worry, ordinary lead-acid battery adaptability is better (adjustable in winter and summer).
