METHOD FOR PRE-DETECTING DEFECTIVE POROUS POLYMER SUBSTRATE FOR SEPARATOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18032565 titled 'METHOD FOR PRE-DETECTING DEFECTIVE POROUS POLYMER SUBSTRATE FOR SEPARATOR
Simplified Explanation
- The patent application describes a method for pre-detecting defective porous polymer substrates used as separators. - The method involves selecting a porous polymer substrate with multiple pores and observing it using a scanning electron microscope (SEM) to obtain an image. - The average value of the pore distribution index (PDI) is quantified and then corrected to obtain a more accurate value. - If the corrected average value of PDI is determined to be 60 a.u. or less, the porous polymer substrate is classified as a good product. - If the corrected average value of PDI is determined to be larger than 60 a.u., the porous polymer substrate is classified as a defective product.
Original Abstract Submitted
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.
