El-Mul Technologies is an Israeli company that has been developing carbon nanotube technology since 2001. They have created carbon nanotube electron emitters and are evaluating them with beta customers. More recently in 2009, they started developing novel electrode materials using carbon nanotubes for energy storage devices like batteries and supercapacitors. Their carbon nanotube electron emitters use a single multi-walled carbon nanotube inside a microcavity that can be gated at low voltages to emit electrons efficiently. They are also working on scalable carbon nanotube arrays for applications like electron guns and x-ray sources. For electrodes, carbon nanotubes improve current collection due to their large surface area and stability in energy devices.
