Partially oxidized carbonaceous materials characterized by substantially homogenous, partially oxygenated surfaces thereof are enabled via microwave-assisted methods that are simple and fast. The exemplary methods include combining carbonaceous material(s), at least one mild oxidizer, at least one nucleophile, and an aqueous solvent system to obtain a mixture; and exposing the mixture to microwave radiation for a predetermined time to produce partially oxidized carbonaceous materials. The predetermined time may be in a range from about 5 seconds to about 2 hours, and the power of the microwave energy may be in a range from about 100 w to about 1700 W. The partially oxidized carbonaceous materials are characterized by a homogeneous distribution of oxygen content in surfaces thereof, in nonzero amounts up to about 10 at %, and a standard deviation of surface oxygen content in a range from about 0.1 at % to about 1.0 at %.

A battery safety system includes a flow valve and a sensing device. The flow valve is disposed on a housing of the battery and includes a first valve that is embedded inside the housing and a second valve that intersects the housing. The first valve includes a cavity through which analytes released upon electrochemical reactions within the battery flow towards the second valve. The second valve extends through the housing to the outside, and defines an opening through which the released analytes exit the housing. The sensing device is disposed within the cavity of the first valve of the valve and is situated in a manner to be in fluidic contact with the released analytes as they flow from the inside of the battery to the outside. In some aspects, the battery safety system can detect a minute presence of one or more analytes. In some aspects, the sensor is in communication with a battery management system.
