The electrolyte of the colloidal battery is a semi-solid and semi-liquid paste. With a large amount of electrolyte, the battery has a large heat capacity, strong heat dissipation ability, and a wide operating temperature range.
The electrolyte of the lead-acid battery is liquid. It has the characteristics of low cost, easy recycling, high current discharge, low energy density, and lead pollution to the environment.
Lithium ion iron phosphate battery is a lithium-ion battery that uses lithium iron phosphate (LiFePO4) as the positive electrode material and carbon as the negative electrode material. It has the advantages of high operating voltage, high energy density, long cycle life, good safety performance, low self-discharge rate, and no memory effect.
As the battery/power reserve power source of the solar system, lithium iron phosphate battery is the first choice, and its charging and discharging is more stable; followed by colloidal battery. The manufacturing originals of the two are different, so users choose the appropriate battery according to their budget.
