  • Patent number: 11940368
    Abstract: Disclosed is a method for pre-detecting a defective porous polymer substrate for a separator, including selecting a porous polymer substrate having a plurality of pores; observing the selected porous polymer substrate with a scanning electron microscope (SEM) to obtain an image of the porous polymer substrate; quantifying the average value of pore distribution index (PDI); correcting the quantified average value of pore distribution index to obtain the corrected average value of pore distribution index; determining whether or not the corrected average value of pore distribution index is 60 a.u. (arbitrary unit) or less; and classifying the porous polymer substrate as a good product, when the corrected average value of pore distribution index is determined to be 60 a.u. or less, and classifying the porous polymer substrate as a defective product, when the corrected average value of pore distribution index is determined to be larger than 60 a.u.

  • Publication number: 20080193853
    Abstract: Disclosed are a pyrrolidinium type sulphonated zwitterion, a method of preparing the same, a lithium salt prepared by using the same, a method of preparing the salt, an electrolytic composition containing the salt and a lithium secondary battery including the electrolytic composition. Since the pyrrolidinium type sulphonated zwitterions prepared according to the invention are thermally and electrochemically stable, the lithium salt prepared by using the same exhibits a lower hygroscopicity than the conventional lithium salts and strong thermal and electrochemical stabilities. When the lithium salt of the invention is dissolved in an organic solvent independently or together with the ionic liquid, excellent conductivity and electrochemical stability are exhibited. Accordingly, the lithium salt of the invention is very suitable for the electrolyte of the lithium secondary battery.
