        Market Definition

        According to Hollingsworth & Vose, a battery separator is a polymeric membrane placed between the positively charged anode and the negatively charged cathode. The separators act as isolators. Ions can freely go across separators, but these are not electrically conductive. The main purpose of battery separators is to isolate the negative and positive electrodes. They must obstruct any processes which negatively affect the electrochemical energy efficiency of a battery. This helps in avoiding electrical short circuits while permitting rapid transportation of ionic charge carriers to complete the circuit during the transit of current in an electrochemical cell.
