The high conductive carbon particles bond tightly with active material, and construct a 3D conductive network, decrease the inner resistance. The battery is of high power density and good recovery. (2) Good charging characteristics: It holds a high charging rate, the max accepted charging current reaches to 4 times of normal VRLA. (3) Excellent high rate discharge performance: Polarization is small in lead-carbon batteries; it holds a lower charging voltage level and higher discharging voltage level, which is benefit for high rate discharge. (4) Long cycle-life: The carbon nanocomposites can limit the growth of PbSO4 crystal, and inhibit the sulfation of negative plates when operate in partial state of charge (SoC) of 20-80%. By using of hydrogen evolution inhibitor, water loss is few. An advanced technology of “crystal introduced” is adopted in positive plate, making the porosity is high, delay the problem of positive active material softening and shedding during using. So, the battery is very suitable for using for high rate partial state of discharge (HRPSoC), the designed cycle life reaches to 15 years (25 ℃). (5) Good environmental adaptation: Adopting Cloudy gel electrolyte and synthetic tanning agent, which improve the environmental adaptation and free maintenance, the batteries can operate at a wide temperature range of -40～60 ℃.
