Test System Measures Gas Permeability of Lithium Ion Battery Separators
2014-07-25 06:00:00| Industrial Newsroom - All News for Today
The separator should not limit the electrical performance of the battery. Usually the presence of a polymer separator will increase the resistance of the electrolyte by a factor of four to five. The ratio of the resistance of the separator filled with electrolyte divided by the resistance of the electrolyte alone is called the MacMullin number. Air permeability can be used indirectly to estimate the MacMullin number. Air permeability is expressed in terms of the Gurley value, which is defined ...This story is related to the following:Air Permeability Testers |
