Abstract
A system is disclosed for protection of a lithium ion battery. The system includes a first light source and a first optical guide including first and second ends. The first optical guide is in optical communication with the light source at the first end of the first optical guide. A first material is disposed on an exterior surface of the first optical guide in fluid communication with an exterior surface of the lithium ion battery. The first material is optically responsive to a first gas indicative of an overheat condition or combustion of the lithium ion battery. A first light detector is in optical communication with the second end of the first optical guide.
