Dans Industrial & engineering chemistry research (Vol. 48 N° 9, Mai 2009)

When a lithium-ion battery is overcharged, it starts to self-heat because of exothermic reactions occurring within the components of the cell. Separator shutdown is a useful safety feature for preventing thermal runaway reactions in lithium-ion [...]

Enhancement of the meltdown temperature of a lithium ion battery separator via a nanocomposite coating

S. H. Yoo, Auteur ; C. K. Kim, Auteur |

Dans Industrial & engineering chemistry research (Vol. 48 N° 22, Novembre 2009)

In a previous study, a lithium ion battery separator was coated with polymers synthesized from various ethylene glycol dimethacrylates to enhance its meltdown temperature. The meltdown temperature of the separator was increased to 155 °C when it[...]
