Maintenance-free liquid battery or lithium battery which is better

Comparing maintenance-free gel batteries and lithium batteries, which one is suitable for different purposes, according to the current situation, when a large number of batteries are used, maintenance-free gel batteries are better than lithium batteries. Like UPS power supply, lead-acid batteries are better, because the cost of lithium batteries is mainly higher than that of batteries, and the problem is safety and other factors. If you need ups power supply or ups battery, you can directly consult us Ubisch.

The difference between lithium battery and gel battery:
1. Environmental protection:
The solar street light lithium battery is pollution-free; the colloidal battery is polluted by the heavy metal lead.
2. Different electrolytes:
The electrolyte of the lithium battery is a non-aqueous liquid organic electrolyte. The electrolyte of the gel battery is a gel electrolyte.
3. Long service life:
At present, lithium iron phosphate has no memory effect after 1500 charging times, and it accounts for about 85% of the storage capacity after 1500 charging times. But the gel battery is about 500 times, and the memory effect is obvious.
4. Security:
There are differences in the safety of power lithium battery materials, that is, the colloidal battery technology is quite mature, and the safety is higher than that of lithium batteries.
5. High efficiency and good performance;
The self-discharge of the gel battery is small, which is conducive to long-term storage; the high depth discharge performance is conducive to improving the utilization rate and discharge capacity of active materials. The deep discharge and overdischarge recovery ability is strong, and the charging acceptance ability exceeds the national standard by more than 50%.
6. Different working principle:
When charging a lithium battery, the lithium ions generated by the positive electrode move to the negative electrode through the electrolyte, and the more lithium ions that reach the negative electrode, the higher the charging capacity. When the battery is discharged, the lithium ions embedded in the negative electrode move back to the positive electrode, and the more lithium ions that return to the positive electrode, the higher the discharge capacity. Gel batteries are sealed using the principle of cathode absorption. The reduction of oxygen at the cathode and the increase of the hydrogen overpotential of the cathode itself avoid a large amount of hydrogen evolution reaction. Compared with batteries, lithium batteries have higher average voltage and energy density. In other words, a battery of the same size has more capacity. In addition, lithium batteries are relatively light in weight, easy to carry, and have a relatively long lifespan. In addition, lithium batteries are more adaptable to high and low temperatures, less affected by temperature, and more environmentally friendly. Of course, lithium batteries also have three shortcomings, and their safety and stability are relatively poor. It may explode if not handled properly. In addition, lithium batteries cannot be discharged with large currents, and the production requirements are high and the cost is high. The emergence of lithium battery products is the realization of the progress of the electric vehicle industry. Although lithium batteries have many advantages, at present, electric vehicles are mainly batteries, and the main factor is that the technology is not perfect. To replace batteries with lithium batteries, the technology must reach a matching height, and the cost performance must be improved in order to be accepted by more people.
Summary: Based on the above comparison, everyone must have an obvious answer to which MAINTENCE FREE SEALED BATTERY or lithium battery is better. Generally speaking, according to the use, each has its own advantages. For example, when a large number of batteries are used, of course, maintenance-free gel batteries are better. For mobile phones, lithium batteries are used, so the description must be clearer.
