NEC is working on an organic radical battery (ORB) which could enable a PC to keep running even when the power supply is disrupted. The ORB will have a max power of 35 watt, but it is expected that several would be utilised together, perhaps even as many as four.

The organic radical battery, or ORB, is based on a similar cell structure to a lithium-ion battery of the type commonly found in devices such as notebook computers and cell phones, but with one significant difference: Instead of using poisonous ingredients like lithium and cobalt, it uses an organic compound called PTMA.
