LG Chem licenses separator film technology to Ube Maxell

LG Chem has agreed to license its separator film technology agreement to Ube Maxell. Under the agreement, Ube Maxell acquires patent use rights from LG Chem for ceramic coating of separator substrates, a key component of lithium-ion batteries.

Ube Maxell, a joint venture between Ube Industries and Hitachi Maxell, was formed in 2011 to manufacture coated separator films for lithium-ion batteries used in hybrid and electric vehicles, as well as industrial applications.

The patent granted to Ube Maxell is for LG Chem’s Safety Reinforced Separator technology, which uses a ceramic coating on separator substrates to enhance the thermal deformation resistance and mechanical strength of separators, which are used to prevent short-circuits inside lithium-ion batteries.
