OPzV series(2V)
Description:
Characteristic description
1. Application fields
Solar/wind energy storage,
Complementary solar/wind grid connected energy storage
Standby power supply for：power station,nuclear power plant; petrochemical industry and marine;
Standby power supply for signal and communication system of internet, railway, airport;
Standby power supply for ocean signal, beacon communication board, and switching station.
2. Executive standards
IEC60896-21/22：2004、IEC61427：2005、YD/T1360-2005、GB/T22473-2008
3. Construction features
Plate: The positive is tubular plate, it can effectively prevent the shedding of active material. Positive grid is casted by multiplex alloy. Alloy microstructure is of fine grains and dense, good corrosion resistance, long cycle life. The negative is pasted plate, grid structure is radial, which improve active material utilization and large current discharge capacity, charge acceptance.
Separator: The polymer microporous separator with low resistance and high porosity is adopted. It has more storage space for electrolyte and higher affinity with gel electrolyte, so the batteries have a longer cycle life.
Electrolyte: The main material is made of fumed silica imported from Germany, it is dilute sol when just injected, it can fill the plate space completely and make the reaction uniformly. The flooded design can avoid the electrolyte dry up when the over-charged or under the high temperature. It is of high heat capacity and good heat dissipation, thermal runaway will not occurs. The electrolyte shows as a gel state in the battery without acid flow, leakage and acid stratification.
Case: Made of ABS material, which is of corrosion resistance, high strength, beautiful appearance, high sealing reliability without risk of leakage.
Terminal sealing: The embedded cooper terminals are of good current carrying capacity and corrosion resistance. The unique double sealed structure can avoid the leakage, ensure the sealing reliability
Valve: technology is originated from Germany, which is of suitable pressure of opening and closing, high reliability, can avoid the expansion or break of the case, as well as drying up of the electrolyte.
4. Integrated Performance:
(1)Long cycle-life: It can reach more than 18 years.
(2)Reliable sealing performance: Reliable sealing performance, without leakage, sealed reaction efficiency reaches to 95% after some cycles.
(3)High initial capacity: The actual capacity will not be lower than the rated capacity at or before the sixth cycle
(4)Small self-discharge rate: The rest capacity after storage for 3 month (25 °C) attains to more than 94%
(5)Good high-rate discharge performance: Gel electrolyte with high conductivity
(6)Flexible and convenient installation: Big cooper terminal structure
