will also volatilize, generally need to add electrolyte, need to be maintained; high-energy environmentally friendly batteries do not need to be maintained, the life of ordinary lead
acid batteries for about 3 years, high-energy environmentally friendly battery life of more than 10 years, greatly improving the power company's
power backup
Reliability and safety.
High-energy environmentally friendly batteries basically solve the main shortcomings of the traditional lead-acid batteries, and many programs to improve the lead-acid batteries compared to the high-energy liquid electrolyte brought about by the improvement of product performance is more pronounced, especially in the field of high-current and high and low-temperature advantages are more prominent, to achieve the electric vehicle power batteries and high-power traction batteries of high-energy and maintenance-free requirements, in particular, the electrolyte environmentally friendly and the manufacturing industry The new concept of environmental protection fully conforms to the fundamental trend of industrial development in the 21st century.
Performance characteristics: High-energy battery is a new concept of electrolyte, the structure of the battery plate and material ratios, as well as the battery into an innovative transformation of the process, and thus the development of high-performance environmentally friendly secondary batteries called "high-energy battery". The application of proprietary technology and unique production process, so that the comprehensive physical and chemical properties of the battery to reach the international leading level. The battery has a long service life (float charging can be used for 10 years), energy (45wh/kg), no pollution (polymerization complex), large capacity (30% more than constant current discharge), short charging time (2-4H), discharge capacity (0.5-1h) in -40 ℃ to 70 ℃ in the extremely harsh climatic conditions can still be normal work, large flow of charging (2.5C), large flow of discharge (10-18C). Discharge (10-18C), low discharge voltage (1.2-1.8V), maintenance-free, small internal resistance (10 milliohms), small self-discharge (monthly ≤ 10% year by year), no memory, electric restoration capacity of the strong (can be used in emergencies), free of charge for a long time (24-36 months), the charge can be used in the factory, the use of the transportation of no leakage of liquid danger, safe and reliable. Countries around the world have been looking for new technology, new technology, new materials, new structures and actively develop new products to meet the higher environmental protection and use requirements. People try all kinds of colloidal electrolyte and new technology to solve the problem of maintenance-free traction battery, the above efforts are due to the characteristics of the lead-acid battery itself is fruitless. Valve-regulated sealed high-energy environmental protection battery is a sealed high-energy battery equipped with self-control valve, valve-regulated sealed high-energy storage environmental protection batteries in normal use, can effectively maintain the gas-tight and liquid-tight state, no need to add water, no electrolyte leakage, no acid mist overflow, and no need to replenish the electrolyte. It has good effect when used in electric vehicles: electric bicycle, electric sightseeing car, golf cart, electric forklift, electric car. In a variety of applications (such as: 1, communication system backup power 2, electric power system backup power 3, aircraft, motor vehicle starting 4, electric vehicle power 5, railway locomotive, passenger car applications 6, peak load compensation energy storage device 7, marine equipment 8, UPS and computer backup power 9, medical equipment 10, deep-sea lighting and power system 11, firefighting and security and defense systems 12, emergency lighting system 13, alarm system 14, solar energy system 15, car start and other areas)
High energy environmental protection storage in some areas are higher requirements, relative to lead-acid batteries to say, there are many limitations.
First, lead-acid batteries, large internal resistance, insensitive to small currents, small current storage, for example; wind power is not suitable,
Second, there is memory, the first charge of how much to determine the capacity of the battery in the future,
Third, lead-acid batteries will be lowered with the temperature, resulting in the electrolyte is not easy to diffuse, the two poles of the active substance of the chemical reaction is slow, resulting in a shortened power time, this is the lead-acid battery, the lead-acid battery is not easy to diffuse, the active substance of the two poles of the chemical reaction is slow. This is the reason why the battery is not durable in winter
.
Fourth, repeated discharge, the battery life echo discharge amount output is not the same, shallow, and affected.
Fifth, the internal resistance is large, and will increase due to the increase in the amount of discharge, discharge to the end of the internal resistance is the largest, the current generated within the pole plate is not good lead sulfate and electrolyte specific gravity decreased, lead sulfate formed white crystals, charging can not return to the original, and thus shorten the life of the battery.
Sixth, lead-acid battery liquid sulfate microelectrolyte, at -10 degrees, lead-acid batteries reflect a significant decline. The national standard low temperature 18 degrees, low temperature -18 degrees, has been difficult to reach the usual capacity of 85%. If special. Need to work at low temperatures, this lead-acid batteries will no longer be suitable,
Seventh, lead-acid batteries, after the first charge, can be up to 2 months without discharge, more than to be scrapped, the discharge time of 20 days or so, the electricity will be self-flowing discharge. So a lot of times, like the car car battery, a long time no use of the car to fight this fire.
