NOVELTY - A battery comprises: a negative electrode including an anode current collector having at least one sheet of carbon nanotubes and semiconductor particles interdispersed within the sheet; a positive electrode including a cathode current collector having at least one sheet of carbon nanotubes infiltrated with mixed metal oxides; and a separator, situated between the negative electrode and positive electrode.    USE - The battery is useful in electronic devices.    ADVANTAGE - The battery makes use of carbon nanotubes which are known to have extraordinary tensile strength, including high strain to failure and relatively high tensile modulus, high resistance to fatigue, radiation damage, and heat.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a method for forming an anode for use in a battery, which involves: forming a cloud of carbon nanotubes; introducing within the cloud, semiconductor particles to form a cloud of a mixture of carbon nanotubes and semiconductor particles; and depositing a volume of the mixture onto a surface so as to form a substantially planar body defined by a matrix of carbon nanotubes with semiconductor particles interdispersed within the matrix;    (2) a method for forming a cathode for use in a battery, which involves: forming a cloud of carbon nanotubes; introducing within the cloud, lithium mixed metal oxide to form a cloud a mixture of carbon nanotubes and lithium mixed metal oxide; and depositing a volume of the mixture onto a moving surface so as to form a substantially planar body defined by a matrix of carbon nanotubes with lithium mixed metal oxide interdispersed within the matrix;    (3) a method manufacturing the battery, which involves: incorporating a set of semiconductor particles into a first a sheet of carbon nanotubes to form a negative electrode; infiltrating lithium mixed metal oxide within a second sheet of carbon nanotubes to from a positive electrode; positioning between the positive and negative electrodes a separator; and sealing the positive and negative electrodes and separator with a casing of carbon nanotube sheet;    (4) an anode for use in a battery, comprising: at least one sheet of carbon nanotubes; and a set semiconductor particles interdispersed within the sheet; and    (5) a cathode for use in a battery, comprising: at least one sheet of carbon nanotubes; and mixed metal oxide infiltrated within the sheet.
