The main advantages and disadvantages between colloid storage battery and lead-acid battery are as follow:
Can high polymer gel battery and lead acid battery to buy often appear such images, can buy high polymeric colloidal battery or lead acid battery, as the function of these two products are similar, so businessmen hesitant would happen at the time of purchase, whether to buy.
Part 1, environmental performance: this product USES the high polymer silicone gel electrolyte instead of sulfuric acid, have been solved in the process of the production and use of acid mist overflows and interface corrosion etc. The problem of environmental pollution, and scrap polymerization silicon battery electrolyte can also make fertilizer, no pollution, easy to handle, battery grid can be recycled.
2, charge acceptance ability: accept ability is an important measure of battery charging technology index. Can high polymer gel battery charged 0.3 0.4 CA current value available, conventional charging time is 3 to 4 hours, only for lead-acid battery charging time of a quarter.0.8 1.5 CA current value can be used fast charging, quick charging time < 1 hour, has exceeded the rate of 0.5 hours. Large current charging, no obvious temperature rise, high poly can gel battery will not affect the electrolyte features and battery life. Can high polymeric colloidal battery quick charging characteristics, to solve the fast charging industry has a broad application prospect.
3, features: large current discharge and recharge capacity, discharge capacity of the battery is also extremely important technical indicators. A rated capacity of the battery it finished in shorter time electricity, and marks its discharge performance. Domestic communication rate of battery discharge standard are 10 hours, rate of power battery for 5 hours. High shaped colloid as electrolyte battery internal resistance, large current discharge characteristic is good, can be widely used 0.6 0.8 CA discharge current value. Power battery discharge capacity requirements are as much as 15 to 30 short time ca. By the national quality inspection center of battery test, high shaped colloidal battery 2 hour rate of discharge capacity has reached the international advanced level.
4, self-discharge features: uniformity, good maintainability, is advantageous for the long time preservation. Because ordinary lead-acid battery self-discharge factors, usually in 20 ℃ environment for 180 days, needs a put/charge maintenance, otherwise may damage the battery life. Can high polymeric colloidal battery due to its internal resistance is only equivalent to one over ten of the lead-acid battery, so its little self-discharge, and no memory effect, room temperature storage for a year, remained 90% of the nominal capacity, capacity the indicators in the international advanced level.
5, full charge full discharge capacity: high shaped colloidal battery full charged full discharge ability. Many times repeatedly the depth charge and discharge even full filling full discharge little impact on the battery, can cancel or reduce the lower limit of 10.5 V (nominal voltage 12 V) protection, this right power battery. It is very important. Lead-acid battery when use a 10.5 V low voltage protection device usually, less than 10.5 V when do not continue to discharge. This not only because of its low pressure performance is poor, more important is deep discharge will damage to the plate.
6, since the recovery ability: high shaped colloidal battery has strong ability of the recovery, rebound large capacity, short recovery time, after put electricity can be used again a few minutes later, this is good for emergency use special.
7, low-temperature characteristics: high polymer gel battery in to 50 ℃ to + 50 ℃ environment can be normal use, the lead-acid battery in less than 18 ℃ environment capacity when using.
8, long service life: used for communication power supply service life of more than 10 years, used as a power source, the deep circulation charge and discharge more than 500 times (the national standard is 350 times).
So if next time you buy batteries in hesitant, you according to the above comparison, and will soon be able to choose the suitable for their goods. Is really save time and effort and worry.
Colloid:
Advantages: large amount of electrolyte, it is not easy to happen and cause by thermal runaway inflation; Cycle life and floating life generally better;
Disadvantages: difficult production technology, high cost;
You said the lead-acid battery I default is refers to the AGM batteries, because the colloid is lead-acid ah.
AGM battery:
Advantages: low production technology difficulty, the cost is low; Charge and discharge performance better;
Weakness: the possible thermal runaway, because too little electrolyte; Overcharge when water loss will lead to battery life greatly shorten;
Gel battery is lead-acid battery gelling agent is added in the sulfuric acid, sulfuric acid electro-hydraulic colloidal becomes. With conventional lead-acid battery is not just about the difference between electro-hydraulic to gel. Solidification states such as water-based gel, look from electrochemical classification structure and characteristics belong to gel battery. And like a knot in the plate grid with high polymer material, commonly known as the ceramic plate gate, can be regarded as the application characteristics of gel battery. Recent laboratory existing in plate, a targeted coupling agent is added to the formula has greatly increased the plate, the utilization of active substance reacts according to nonpublic information can reach 70 Wh/kg weight specific energy levels.
1: colloidal battery internal mainly SiO2 porous mesh structure, there are a large number of tiny cracks, with smooth migration of oxygen of the anode to the cathode plate, is advantageous for the negative absorption combination;2: colloidal battery with acid amount is larger, so its capacity and AGM battery almost the same;3: colloidal battery internal resistance is bigger, better generally have no large current discharge characteristic;4: heat is easy to spread, not easy to heat up, thermal runaway chance is very small;
This composition or sulfuric acid, water and silica gel formed. Therefore, the electrochemical action is still water, sulfuric acid. The reaction process is not much difference, however, changes in the structure, can bring many benefits. Specific or Mosaic net friend, please introduce some more.
Gel battery in China, and now are using AGM separator. Early on, I write also had to beat China's gel battery on quotes, in a show of gel battery with Germany to distinguish it. Then write many, also ignored. Besides called gel battery in China, there are many a variety of call methods. Such as: "the lead crystal battery", "solid batteries", "silicon battery", "silicon cells,"...
Mosaic netizens said domestic gel battery, at the time of glue, and half filled also has, they call themselves the "half gel battery", lower and common electrolyte, the upper is colloid.
The advantage of gel battery was good cycle life, over discharge resistance, can be not enough electricity for a long time and discharge (AGM battery using sulfide failure are likely to happen), high and low temperature performance is also better than AGM.
In plain English is resistant to some abuse.
I said this lithographic paste plate gel battery very few domestic manufacturers, in addition to our volunteers, the output of Shuangdeng also not small, other large factory have nothing.
This kind of gel battery cost is significantly higher than normal cells, are generally industry users to use.
Colloid lead-acid storage battery is the improvement of ordinary lead-acid battery liquid electrolyte, by substituting colloid electrolyte sulphuric acid electrolyte, in safety, storage capacity, discharge performance and service life than ordinary batteries have improved.
Colloid lead-acid storage battery using gel electrolyte, inside there is no free fluid, electrolyte under the same volume large capacity, heat capacity, heat dissipation ability strong, can avoid battery are prone to thermal runaway phenomenon; The electrolyte concentration is low, weak corrosion effect of plate; Concentration is uniform, there is no electrolyte stratification.
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 domestic colloid lead-acid battery for electric bicycle is by vacuum infusion in the lining of the AGM, the silica gel and sulphuric acid solution between irrigation to the battery positive and negative plate. Colloid lead-acid battery to oxygen cycle at the beginning of use, this is because the colloid has surrounded the positive and negative plate, positive plate of oxygen diffusion to the negative plate to the above, cannot be achieved with the active material of lead on the negative plate reduction, can only through the exhaust valve, consistent with rich liquid type battery.
The colloid of colloid lead-acid batteries began to dry and shrinkage after using for a period of time. It has cracks, and oxygen passes through the cracks directly to the negative plate. Exhaust valve does not always open, and colloid lead-acid battery is close to sealing work, little water loss. So main failure mechanism for electric bicycle battery is water loss, the colloid lead-acid battery can obtain very good results. Gel electrolyte adds gels to sulfuric acid in the electrolyte solidified into colloidal substances, and there are colloid stabilizer and compatibilizer in the colloidal electrolyte. Some gel formula have delay colloid solidification and retardant, which is convenient for colloid filling.
