1. A method of powering an electronic device, comprising:

  • a) providing an electronic device comprising a lithium ion cell wherein the lithium ion cell comprises an anode and cathode wherein the anode comprises nano-crystalline Li4Ti5O12;

    b) charging the lithium ion cell; and

    c) discharging the lithium ion cell to power the electronic device;

    wherein the lithium ion cell can be charged and discharged within a temperature range between 130°

    C. and 250°

    C. and voltage range between 1.5 V and 4.2 V, and wherein the charging and discharging of the lithium ion cell results in a safety coefficient greater than 100.
