ENTEK Announces Major Expansion of U.S. Lithium-ion ...
Design of single-layer thermal resistant separators. A safe and reliable single-layer separator should have two safety-related properties: a high melting temperature (T m) and low thermal shrinkage.The T m of traditional PE and PP separators are 140 C and 160 C respectively, which exhibit obvious shrinkage at high temperature and trigger …
1. Introduction Since being commercialized by Sony in 1991, significant progress in lithium-ion batteries (LIBs) technology have been made. For example, the energy density of LIBs has increased from ca. 90 to 300 Wh kg −1, giving a clear competitive advantage over the counterparts such as lead-acid, nickel–cadmium, and nickel-metal …
