The battery is divided into ordinary battery and gel battery from the structure, the latter is also called maintenance-free battery.
The simplest method of colloid battery is to add gelling agent to sulfuric acid to make sulfuric acid electrohydraulic state.
Electrohydraulic gel batteries are usually called colloidal batteries.
The difference between gel battery and conventional lead-acid battery is not only in the change of electro-hydraulic to gelation.
For example, non-solid aqueous colloids belong to colloidal batteries from the structure and characteristics of electrochemical classification.
For example, the decomposition of polymer materials in grids, commonly known as ceramic grids, can also be regarded as the application features of colloid batteries.
The biggest difference between colloid batteries and ordinary batteries is that there is a group of water openings at the top of ordinary batteries, which must be carefully observed when choosing and purchasing, because some manufacturers block them with a delicate plastic cover.
There is an observation hole on the top of the colloidal battery, the color in the hole indicates the state of the battery, green indicates normal, black indicates power loss, white indicates that the battery has been damaged and should be replaced as soon as possible.
The main advantages of colloid battery are high quality and long cycle life.
The colloidal electrolyte can form a solid protective layer around the plate to protect the plate from damage and rupture due to vibration or collision, and to prevent the plate from being corroded. at the same time, it also reduces the bending of the plate and the short circuit between the plates when the battery is used under heavy load, which will not lead to a decrease in capacity. it has good physical and chemical protection, which is twice the life of ordinary lead-acid batteries.
The utility model has the advantages of safety and environmental protection, and belongs to the green power supply in the real sense.
The electrolyte of the colloid battery is solid, sealed structure, gel electrolyte, never leak, so that the specific gravity of each part of the battery is consistent.
The use of special calcium-lead-tin alloy grid, more corrosion resistance, better charge acceptance.
Ultra-high strength diaphragm is used to avoid short circuit.
Imported high-quality safety valve, precise valve control to regulate pressure.
Equipped with acid fog flameproof device, more safe and reliable.
When in use, there is no acid fog gas precipitation, no electrolyte spillover, no harmful elements in the production process, non-toxic, no pollution, avoiding a large number of electrolyte leakage in the use of traditional lead-acid batteries.
The floating charge current is small, the calorific value of the battery is low, and the acid delamination does not occur in the electrolyte.
The performance of deep discharge cycle is good.
The capacity of the battery can be recharged 100% after deep discharge and then recharged in time, which can meet the needs of high frequency and deep discharge, so its range of use is wider than that of lead-acid batteries.
The utility model has the advantages of small self-discharge, good deep discharge performance, strong charge acceptance, small potential difference between upper and lower potential and large capacitance.
It has been significantly improved in low temperature start-up ability charge retention electrolyte retention cycle durability vibration resistance temperature change resistance and so on.
Stored at 20 ℃ for 2 years, it can be put into operation without charging.
Adapt to a wide range of environment (temperature).
Can be used in the temperature range of-40 ℃-65 ℃, especially good low temperature performance, suitable for northern alpine areas.
It has good anti-seismic performance and can be used safely in all kinds of harsh environment.
It is not limited by space and can be placed in any direction when in use.
It is quick and convenient to use, and because the internal resistance, capacity and floating charge voltage of the single battery are consistent, there is no need for balanced charging and frequent maintenance.
