Wuhan Yunhong Electronics Power Co.,xxxxx a high technology enterprise specialized in the research,development and production of 3.6V and 3.0V primary cylindrical Lithium as one of the greatest suppliers in China. Wuhan Yunhong Electronics Power Co.,LTD. was established in 1994. YUNHONG is provided with the modernest technology of lithium primary battery in the world, and it has set up a big factory with the production capacity of 10,000,000 per annual in Wuhan. The products include: Thionyl Chloride Lithium battery (ER series Li-SOCl2 ), Manganese Dioxide Lithium Battery (CR series Li-MnO2 ) . Wuhan Yunhong Electronics Power Co.,LTD. has been carrying through ISO9001:2000 Quality Control system . Yunhong emphasizes to set up a strong corporation culture, and initiate strictness, carefulness work style,and treat people sincerely.To stir up the employee&＃039;s creation talent. Taking"system management , advance in technology, the best quality and value added service" as its quality policy. As a kind of the most reliable and stable cell with high technology, the type of primary cell gets quite high density up to 420WH/kg and high voltage up to 3.60V/cell. Spiral electrodes construction makes it can be discharge at large rate. No-magnetic stainless steel case and hermitically sealed construction makes it can be used in somewhere that other batteries cannot be used. As a kind of lithium battery, it gets definitely cheap cost but also high energy density at 270WH/kg, high voltage of 2.7V~3.0V/cell and other good performance. Its cylindrical and button outlook make it to be widely used in industrial and consumer area. It gets no-magnetic stainless container and can be hermetically sealed or semi-sealed. Its spiral construction makes it can be discharge at high rate.
