Gel battery and lithium battery comparison for solar power projuect?
51.2V/300AH Power wall Lithium battery
The following information for Gel battery and lithium battery comparison, what can help you determine to use what kind of batteries for your solar solution.
1. Environmental protection: The lithium battery has no pollution; the gel battery has heavy metal lead pollution.
2. Different electrolytes: The electrolyte of lithium batteries is non-aqueous liquid organic electrolyte, and the electrolyte of gel batteries is gel electrolyte.
3. Service life: At present, lithium iron phosphate is generally charged 1500 times without memory effect. After 1500 charges, it accounts for about 85% of the storage capacity, while gel battery is about 500 times with obvious memory effect.
4. Safety: The safety of power lithium battery materials is different. The gel battery technology is quite mature. It is safer than lithium batteries, has high efficiency and good performance: gel batteries have small self-discharge, which is beneficial to long-term storage, and have high deep discharge performance.
It is conducive to improving the utilization rate of active materials and discharge capacity. It has strong recovery ability from deep discharge and over-discharge, and its charge acceptance capability exceeds international standards by more than 50%.
5. Different working principles: When charging a lithium battery, the lithium ions generated on the positive electrode move to the negative electrode through the electrolyte. The more lithium ions that reach the negative electrode, the higher the charging capacity; when the battery is discharged, the lithium embedded in the negative electrode The ions move back to the positive electrode.
The more lithium ions that return to the positive electrode, the higher the discharge capacity. Gel batteries use the principle of cathode absorption to seal the battery. The reduction of oxygen on the negative electrode and the increase in the hydrogen overpotential of the negative electrode itself eliminate a large amount of oxygen evolution reaction. As for whether a gel battery or a lithium battery is better, it depends on the actual usage. When making judgments, different usage scenarios will have different usage choices and different conclusions.
