The development process is strictly controlled and improved by national grade scientists and research team. Nowadays the technology is mature and applied in mass production.

Market study shown NCSLA is considered as the replacement version of Germany Gel battery and become the replacement and upgrading product for current standard lead-acid batteries. NCSLA is widely used in all kinds of UPS, vehicles, electric cars, emergency system, solar power system, wind power system. NCSLA provides strongest and lowest cost support for premium precision equipments, energy storage and communication systems. It is widely distributed over the world, received recommendation and good commends by users.

Comparisons

Standard Maintenance Free SLA Standard Characteristics

A.              In room temperature 25℃,standard deep cycle life 150-180 times.

B.               In room temperature 25℃, deep discharge recovery ability is poor. Deep discharge voltage cannot set below 10.5V / 12V battery, over discharge will not able to recover to standard capacity.

C.               In high temperature, standard SLA is not stable. At 55℃, will cause thermal run-away.

D.              In low temperature, -18℃-22℃, it cannot be functioned, and no electric power can be generated.

E.               Shock-resistance is not sufficient. High current discharging in vibration will cause whole structure to breakdown, and battery will fail.

NCSLA characteristics

A.              In room temperature25℃, standard deep cycle life 600-800cycles, recent test shown should over 1000 cycles.

B.               In room temperature25℃, it is not absolutely required to set lowest limit. And it is capable to recover from over-discharge to 0 Volt.

C.               In over65℃, no thermal run-away, use as normal.

D.              In extreme low temperature -40℃, it is well-functioned and able to retain about 22% capacity.

E.               Shock resistance is excellent due to nano capsular structure. The enhanced mechanical strength allows NCSLA to work at shock environment, and provide high power as normal condition.

Brief Theory:

1.    Reduced acidic gradient: Since the floating molecules are nano scale particles, which has excellent penetration ability. It can evenly adhesive to electrode surface, and significantly reduced acidic gradient in operation.

2.    Excellent deep discharge recovery: The nano particles have 2-3 times of coefficient of expansion between absorption and release, the lead electrode have coefficient of expansion 1.4. Therefore, the compensation relationship effectively enhanced the adhesive ability of active particles.

3.    Increased Cycle Life: Due to the physical characteristics of compensation relationship, the peal off of the lead particles reduced and therefore, significantly increased the life cycles of the battery. Also, less peal off of active particle will cause less “Electric Bridge” at the bottom which is another reason of short life.

4.    Reduced Sulphation: Nano capsular molecules adhesive to active materials effectively reduced the rate of sulphation. This is the main characteristic which elongate the life and stand against over discharging.

5.    Efficiency of Charge/Discharge: The even distribution of nano particles provided even ability of acceptance of charge, and also, formed ion exchange channels. The ion exchange channels improved ability of oxygen / hydrogen ion exchanges, which in return reduced the internal resistance of battery. The efficiency of charge/discharge is therefore enhanced.

6.    Shock resistance: In case of battery working in vibration environment, especially simultaneous working at high power charge or discharge, is the main cause of the electrode plate breakdown. The nano particles are distributed amount the electrodes. Its excellent physical flexibility and mechanical strength compensated and absorbed the impact forces and reinforced the active particles.

7.    High temperature endurance: Standard lead acid battery will have thermal run-away at around 55℃ high temperature. NCSLA can stand upto 65℃ high temperature and will not have thermal run-away.

8.        Low temperature ability: Standard lead acid battery will not working at -18℃~-22℃. But nano particles will not frozen at low temperature, the conduction channels still maintained in the particles. NCSLA can therefore provide 22% capacity at -40℃ environment.

Conclusion:

Nano Capsular Sealed Lead Acid Battery is the second generation of SLA Battery, the replacement of traditional Lead Acid Battery. NCSLA is recognized by it long cycle life, environmental adaptation ability, and supreme characteristics. Its’ electric/acidic media is excellent. All users have confirmed and appreciated its superior performance.
