Is the gasket silicone? Food grade silicone?

Of course, water bottle cushions are basically made of food-grade silicone, and rarely used other materials.

Can the bottle be refrigerated?

yes,since it can keep warm, it can also keep cold.You can use it to make coffee or tea in winter and ice water in summer

Yes most definately. My boyfriend loves his and takes it to sork everyday and it stays hot for his entire 8HR shift :)

Can you tell me how to change the battery?

I am sorry,battery replacement is not supported,but don't worry about that,We use intelligent design, the LED will only go out for a few seconds, we test that the LED can be displayed more than 50000 times.That's 3+ years of usage!Almost the life of the thermos cup.
