In May of 2014, UBE Maxell signed a licensing deal with LG Chem for use of the battery maker's patented Safety Reinforced Separator (SRS) technology, which uses a ceramic coating on separator substrates to improve the thermal deformation resistance and mechanical strength of separators.

Now, Shenzhen Senior Technology (Senior) of China has entered into a similar deal with LG Chem for use of SRS.

LG Chem has released this statement on the deal:

“With the latest licensing deal, we will be able to create an additional income source, while maintaining a strategic relationship with Senior in battery core materials."

“SRS technology played a crucial role for us to expand our battery partnership with major car manufacturers and leading electricity companies such as General Motors, Renault, Volvo, Audi, Siemens, AES and SCE. We hope to seal additional paid agreements as LG Chem has been receiving requests whether or not to share our technology."

LG Chem’s SRS technology was patented in Korea in 2007, followed by the United States, China, Europe and Japan.  It's obvious that there's something special about SRS.  Evidence of that is in these two deals for use of the tech.
