Bare/CSS
Bare Film Separator
											WCP – Sequential 
Stretching Process
- Faster production speed
 - Require advanced technology
 - High uniformity
 
											Other Manufacturers - Simultaneous Stretching Process
- Lower ratio of effective area
 - Stretching rate fixed at up to 6 times
 - Difficult to implement strength in certain level
 
Ceramic Coated Separator
