Product Description

Green friendly batteries Winpow AA size

Cathode: Manganese Dioxide (MnO2)
Electrolyte: Ammonium chloride or zinc chloride dissolved in water
In an ordinary Leclanché cell the electrolyte consists (in percent of atomic weight) of 26% NH4Cl (ammonium chloride), 8.8% ZnCl2 (zinc chloride), and 65.2% water.

The overall cell reaction can be expressed:
Zn + 2MnO2 +2NH4Cl -> 2MnOOH + Zn(NH3)2Cl2 E=1.26
The electrolyte in a typical zinc chloride cell consists of 15-40% ZnCl2 and 60-85% water, sometimes with a small amount of NH4Cl for optimal performance.
The overall cell reaction of the zinc chloride as the electrolyte can be expressed:

Zn + 2MnO2 + 2H2O + ZnCl2 -> 2MnOOH + 2Zn(OH)Cl
MnO2, is only slightly conductive, so graphite is added to improve conductivity. The cell voltage increases by using synthetically produced manganese dioxide instead of that found naturally (called pyrolusite). This does drive the cost up a bit, but it is still inexpensive and environmentally friendly, making it a popular cathode.

These cells are the cheapest ones in wide use, but they also have the lowest energy density and perform poorly under high-current applications. Still, the zinc carbon design is reliable and more than adequate for many everyday applications.

WINPOW specializes in battery R&D and production. We provide a wide variety of battery products, including alkaline button cells, 23A/27A batteries, lithium manganese button cells (CR2032), LR6/LR03 alkaline cylinder batteries, R6/R03/6F22 Carbon zinc batteries, lithium primary cylinder batteries (CR123A, ER14250), zinc air batteries and rechargeable batteries (Ni-MH, lithium ion and lead acid).

Huizhou WINPOW Electronic Co., Ltd, the first plant of WINPOW, was established in April 2007. Through over a decade of efforts, we have built three plants, one in Huizhou for producing alkaline button cells and 23A/27 batteries, one in Shenzhen for providing battery diaphragm, and one in Shaoyang for supplying lithium batteries.

As a battery specialist, WINPOW has independent IP rights and R&D capabilities in batteries and are already at the forefront of the industry for many years. We are home to a host of industry professionals who have their papers published in authoritative magazines of China's battery industry, such as Battery and Battery Industry. Our products are widely embraced for extraordinary cost performance and superb leakage resistance. WINPOW's 23A, 27A, and lithium manganese button cells are best-selling products in Chinese battery market, which makes WINPOW an authorized manufacturer of many reputable brands.

Driven by the goal of going global, we established WINPOW (HK) Co., Ltd and WINPOW Industry Co., Ltd. As yet, WINPOW has extended its footprint throughout more than 40 countries and regions including Europe, North America, South America, and Middle East, and its exports are still increasing at an annual rate of 20%. Today, WINPOW's diversified products and premium services are accessible to customers from all around the world.

WINPOW will always keep to its business philosophy of being "customer-centric, honest in cooperation, innovative, and in pursuit of excellence. We will stay focused on battery R&D and production and push WINPOW forward to be a world-leading battery manufacturer.
