Japanese electronics maker NEC said on Friday it was in the process of developing a high-power organic radical battery, or ORB, that could be used in standard desktop PCs as a built-in emergency power source in the event of a power failure...

...NEC also offered other advantages to the technology, such as its environmentally safe composition and the fact that the materials within the battery are both non-flammable and non-explosive, unlike other batteries.

Seems like an excellent alternative to the large, heavy, and environmentally hazardous UPS devices in use today.
