One, colloidal battery
Colloidal lead-acid battery is an improvement of common lead-acid battery with liquid electrolyte. It uses colloidal electrolyte to replace sulphuric acid electrolyte, which is better than ordinary battery in safety, charge storage, discharge performance and service life.
Colloidal lead-acid battery uses gel electrolyte, no free liquid exists in the internal, under the same volume of electrolyte capacity, heat capacity, heat dissipation ability is strong, can avoid the common battery easy to produce heat out of control phenomenon; The electrolyte concentration is low, and the corrosion of the plate is weak. The concentration is uniform and there is no stratification of electrolyte.
The working principle of
Colloid lead-acid battery performance is better than that of valve-control sealed lead-acid battery, colloid lead-acid battery has the use of stable performance, high reliability, long service life, temperature adaptability to the environment (high and low temperature), take a long time discharge capacity, cycle discharge capacity, depth of discharge and large current discharge ability is strong, have to over charge and discharge protection, etc.
The colloidal lead-acid battery used in electric bicycle is filled between positive and negative plates of the battery by silica gel and sulfuric acid solution through vacuum perfusion in the AGM partition. Colloidal lead-acid battery in the early use of oxygen cycle, this is because the colloidal positive and negative plates are surrounded, the oxygen generated above the positive plate can not be diffused to the negative plate, can not achieve and negative plate active substance lead reduction, can only be discharged by the exhaust valve, and the rich liquid battery.
After a period of use of colloidal lead-acid batteries, colloids begin to dry and shrink, resulting in cracks, through which oxygen circulates directly to the negative plate. Exhaust valve is no longer often open, colloidal lead-acid battery close to sealing work, water loss is very small. Therefore, in view of the main failure of electric bicycle battery is water loss mechanism, the use of colloidal lead-acid battery can obtain very good results. Colloidal electrolyte is by adding gel agent in the electrolyte to solidify sulfuric acid electrolyte into colloidal substances, usually colloidal electrolyte is also added with colloidal stabilizer and compatibilizer, some colloidal formula is also added with colloidal solidification and retarder, in order to facilitate colloidal filling.
Colloidal battery and lead acid battery difference
The performance characteristics of
1, gas phase silicon dioxide preparation of high quality colloid, electrolyte evenly distributed, there is no acid stratification phenomenon.
2, the electrolyte is gel fixed state, no flow, no leakage, so that all parts of the plate uniform reaction.
3, the use of tight assembly technology, with excellent high discharge performance.
4, excessive electrolyte, battery heat capacity, heat dissipation ability, wide operating temperature range.
5, all adopt high purity raw materials, battery self-discharge is very small.
6, using gas recombination technology, the battery has a high sealing reaction efficiency, no acid fog precipitation, safety, environmental protection, no pollution.
7, the use of special design and high reliable sealing technology, to ensure the battery is sealed, safe and reliable use.

Two, lead acid battery
The electrodes are mainly made of lead and its oxides, and the electrolyte is a battery in sulfuric acid solution. English: Lead- acidBattery In discharge state, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead. In charge state, the main components of both anode and cathode are lead sulfate. It is divided into exhaust battery and maintenance-free lead-acid battery.
The performance characteristics of
1, safety seal
In normal operation, the electrolyte will not leak from the terminals or housing of the battery.
2. No free acid
Special suction screens keep the acid in. There is no free acid inside the cell, so the cell can be placed anywhere.
3. Deflating system
When the battery pressure exceeds the normal level, VRLA (Valve-regulated lead AcidBattery) will release excess gas and automatically re-seal the battery to ensure that there is no excess gas in the battery.
4, simple maintenance
No water is needed to use the battery, thanks to the unique gas compounding system that converts the generated gas into water.
5, long service life
The corrosion resistant lead-calcium alloy plate is used, and the battery can float for 10-15 years.
6, stable quality, high reliability
With advanced production technology and strict quality control system, the battery has stable quality and reliable performance. Voltage, capacity and seal are checked 100% on line.

Three, colloidal battery and lead acid battery difference
Colloid lead-acid storage battery is the same as the ordinary lead-acid battery in performance, but the inside of the battery electrolyte is an emulsion coagulation state, is a liquid state, liquid state of ordinary lead-acid battery in use process need not add distilled water maintenance regularly, don't need to add distilled water of colloid maintenance (commonly referred to as free maintenance).
Colloidal lead-acid battery is the disadvantage of overload charge and discharge is very harmful, once the overload charge and discharge will cause the irreparable battery, even scrap, and ordinary lead-acid battery overload caused by plate deformation and vulcanization can be small current charge and discharge recovery (just can not restore the original state); Personally feel colloidal clean, worry, ordinary lead acid battery adaptability is better (winter and summer adjustable).
