Abstract: An electronic device includes a housing structure including a first cover facing in a first direction and forming a first surface of the electronic device, and a second cover facing in a second direction opposite to the first direction and forming a second surface of the electronic device. The electronic device also includes a display positioned in a space formed by the housing structure and exposed through the first surface. The electronic device further includes an energy harvesting structure positioned in the space and configured to generate a current from a contact input to the first surface and a sound input generated inside and outside the electronic device. The electronic device additionally includes a battery positioned in the space. The electronic device also includes a charging circuit configured to charge the battery using the current received from the energy harvesting structure.

Abstract: An electrode assembly and a lithium ion battery are provided. An electrode assembly includes (1) an anode plate that includes an anode active material which in turn includes a first lithium metal oxide and a second lithium metal oxide, and (2) a cathode plate that includes a cathode active material which in turn includes a graphite-based composite. The number of dissociated lithium ions included in the second lithium metal oxide is larger than the number of dissociated lithium ions included in the first lithium metal oxide. An electronic device including the lithium ion battery is also provided.
