"overcomes low mixing strength/ performance degradation by controlling polytetrafluoroethylene binder's structure rather than changing material itself... add small amount of binder forming thread-like fibrous network, densely connecting active material/ conductive additive, ensuring uniform dispersion/ mixing... then remaining binder added creating rope-like fiber binding entire electrode together, increasing electrode's strength/ stability... with pouch-type lithium metal anode 349 Wh/kg energy density, about 40% improved"
