Lithium Rods are essential for research and development laboratories worldwide. With their low density, high electrochemical potential and good thermal conductivity, lithium has become indispensable for battery technologies. The uniform shape of our lithium rods also makes them ideal for use as counter electrodes and neutron detectors in nuclear research. Offered as part of our extensive range of lithium products, these rods provide scientists and engineers with a convenient lithium source for prototypes and small-scale devices.
