Abstract: A lithium ion battery and process for producing the same. The lithium ion batteries include a cathode, an anode, a separator, an electrolyte and a battery housing which receives these components. The cathode, the anode, the separator or any other reservoir located in the battery housing and differing from the electrolyte contains one or more organic or inorganic nitrates or one or more organic or inorganic nitrites and the anode contains silicon particles with a silicon content of ?90 wt. % in relation to the total weight of the silicon particles.
