Anatomy of the electric vehicle market can not popularize the cause of gel batteries
The progress of energy is accompanied by the development of the electric vehicle industry. Every technological innovation of lead-acid batteries will be a milestone in the history of the development of the electric vehicle industry. And lead-acid batteries along the way are lithium batteries, nickel-metal hydride batteries, gel batteries. In particular, colloidal batteries, usually manufacturers will use "the most standard laboratory data" as evidence for the user's commitment to the performance of the gel battery! For example: "Continuous mileage, three-pack period of 18 months to 24 months, cost-effective higher. Because its performance is portrayed as "heart-beating", some customers lose their judgment! The most obvious manifestation of this phenomenon was in 2003. A throttle is the mechanism by which fluid flow is managed by constriction or obstruction.

In the actual use process, time has made a fair ruling, what is the situation in the five years that the gel battery has come all the way?
First, the market share is almost zero; second, most users react with colloidal batteries that are severely swelled by heat in the summer, causing the battery to “suddenly dieâ€; third, the colloidal battery may cause an explosion, causing a fire; The performance is very poor, and there may be no large current when the power is urgently needed.
For these hard injuries of colloidal batteries, the reasons for this, industry experts believe that there are the following six 1. In theory, the colloidal battery has the same volume capacity, longer life, better high temperature and low temperature performance. However, due to the domestic production of colloidal batteries, whether it is the plate formulation or the gel infusion, it is not carried out according to industry standards, so there are problems such as low performance and short life.
2. At present, the domestic colloidal battery for electric bicycle is different from the foreign colloidal battery. The domestically produced is in the AGM separator, and the silicon chamber and the sulfuric acid solution are poured between the positive and negative electrodes of the battery through vacuum infusion.
3. Domestic colloidal batteries are beginning to be rich in liquid, unlike other valve-regulated sealed lead-acid batteries . The gel battery is in the early stage of use; the oxygen circulation of the valve-regulated lead-acid battery cannot be performed because the colloid encloses both the positive and negative plates. That is, the oxygen generated on the positive electrode plate cannot be diffused to the negative electrode plate, and the lead reduction of the active material on the negative electrode plate cannot be achieved. Can only be discharged from the exhaust valve. Consistent with flooded batteries. Therefore, the rubber particles taken out by the early exhaust gas are acid-containing, and the rubber particles are easily adhered to the outer casing of the battery, so some users report that the battery leaks acid.
4. After the gel battery is used for a period of time, the colloid begins to crack and shrink, causing cracks, and oxygen passes through the crack directly to the negative plate for oxygen circulation. Although the oxygen cycle suppresses water loss, the excellent oxygen cycle also generates heat, which causes the internal temperature of the battery to rise, and even forms thermal runaway, causing the crack to increase, and the life of the internally broken battery is suddenly terminated.
5 The sulfuric acid resistance of the gel body is much larger than the liquid, which causes the battery voltage drop to be large when the electric motor starts at a large current, and the motor starting torque drops, and the user feels weak.
6. According to ALABC (International Federation of Lead-Acid Accumulators), the average life of a colloidal battery is 30% of a valve-regulated sealed battery. This is also the main reason why gel batteries have better low temperature properties but cannot be promoted on electric vehicles.
Because the polymer in the colloid is weak in conductivity, it is generally not recommended as a power battery, especially for electric vehicles that are often used as vehicles. It is recommended that electric vehicles first use a cost-effective lead-acid battery, followed by a new generation of lithium ions. battery.
If the gel battery is as good as the advertisement, why do a large number of electric vehicle users choose a lead-acid battery? Five years have proved that lead-acid batteries are still the preferred energy source for transportation!
An engine's power can be increased or decreased by the restriction of inlet gases (i.e., by the use of a throttle), but usually decreased. The term throttle has come to refer, informally and incorrectly, to any mechanism by which the power or speed of an engine is regulated. What is often termed a throttle (in an aviation context) is more correctly called a thrust lever, particularly for jet engine powered aircraft. For a steam engine, the steam valve that sets the engine speed/power is often known as a regulator.
