• name: Battery Separators

    Shanghai Shi-Long Hi-Tech Corp., Ltd has been engaging in the researches on applied radiation technology, radiation high polymer modification, products research and development for over 30 years, the developed three series and over 30 varieties of battery separator products are widely used in various kinds of batteries applied in the fields of aerospace, aviation, national defense, transportation, electric power, telecommunications, port and equipment manufacturing, and household appliances thanks to its excellent performance and reliable quality, 
    Unique radiation cross-link, radiation grafting, coating and laminated technologies provide the alkaline battery separator with perfect and comprehensive characteristics:    Excellent chemical stability and high anti-oxidation ability
  •     Quite lower electrolyte resistance
  •     Wider applied temperature range 
  •     Stronger capability of retarding migration of active particles of electrode
    As a result, to completely meet the technical specification and qualified service and shelf lives of batteries applied in varieties fields.

Typical Application

1. Secondary vented Cd/Ni battery

2. Secondary high, medium and low drain’s Zn/Ag2O batteries

3. Secondary Zn/Air battery

4. Super-Capacitor

5. Secondary M(H)/Ni battery

6. Secondary Zn/Ni battery

7. Zn/Ag2O, Zn/MnO2 and Zn/Air button cells

8. Li/ MnO2 button and cylindrical cells

 

 

Advanced Characteristics

1. Excellent chemical stability and high anti-oxidation ability

2. Wider temperature range for applications

3. Strong capability of retarding migration of active particles and preventing penetration by zinc dendrites

4. Ensure the batteries a much longer shelf and service lives

 


Core technologies and service
 
    Shanghai Shi-Long Hi-Tech Corp., Ltd. was formerly the Applied Radiation Technology Research Department of Shanghai Institute of Nuclear Research, Chinese Academy of Sciences.
    Since the 1970s, it has been engaging in the researches on applied radiation technology, radiation high polymer modification, products research and development for more than 30 years, as the result, the Shi-Long have initiated a crowd of core technologies and techniques, the main core technology are
  • Radiation cross-linking
  •  Radiation grafting copolymerization
  •  Coating technology 
  •  Laminating technology etc. 
    Base on sustainably carried out the innovations strategy on technology, products and service which   provides the Shi-Long alkaline battery separator with higher technology barrier and competitive advantage.
    Cooperative technology research and product development is encouraged for special and unique application of battery by means of owned core technologies to meet the sustainable development demand in battery industry.
