First and second terminals extend out of the protective casing, the first and second terminals being connected to different electrodes of the battery cell.

Laminated lithium battery

A lithium battery comprises a support, and a plurality of battery component layers on the support, the battery component layers including a cathode having a cathode area with a plurality of cathode perimeter edges. An electrolyte is on the cathode, and an anode is on the electrolyte. The anode comprises an anode area with a plurality of anode perimeter edges, each anode perimeter edge having a corresponding cathode perimeter edge that lies adjacent to and below the anode perimeter edge. The anode area is sized so that at least one anode perimeter edge is terminated before its corresponding cathode perimeter edge to define a gap between the anode perimeter edge and the corresponding cathode perimeter edge, the gap having a gap distance G.

Lithium battery having low leakage anode

A solid-state, mismatched battery comprises a first battery cell having a first internal resistance, and a second battery cell having a second internal resistance, the second internal resistance being a predefined resistance that is less than the first internal resistance. One or more of electrical connectors electrically couple the first and second battery cells. A casing encloses the first and second battery cells. A pair of terminals is electrically coupled to the first and second battery cells to output electrical power to an external load.

A method of depositing lithium-containing films on a battery substrate in a sputtering chamber is provided. At least one pair of sputtering targets that each comprise a lithium-containing sputtering member is provided in the sputtering chamber, the sputtering targets selected to each have a conductivity of at least about 5&#xd7;10S&#xb7;cm. A substrate carrier holding at least one battery substrate is placed in the sputtering chamber. A pressure of sputtering gas is maintained in the sputtering chamber. The sputtering gas is energized by applying to the pair of sputtering targets, an electrical power at a frequency of from about 10 to about 100 kHz.

Sputtering lithium-containing material with multiple targets

A battery packaging method comprises providing a battery comprising at least one battery cell on a substrate, the battery cell comprising a plurality of electrodes about an electrolyte, and the battery having at least one open peripheral side surface. A thermoplastic bead is provided at an open peripheral side surface of the battery. A cap is placed over the battery and in contact with the thermoplastic bead. The thermoplastic bead is locally heated by directing an energy beam onto the thermoplastic bead, the energy beam having a beam width sized sufficiently small to heat a beam incident region on the thermoplastic bead substantially without heating adjacent regions.

Thin film battery packaging formed by localized heating

A plasma deposition method deposits a battery component material on a partially fabricated battery cell comprising a battery component layer containing charge-carrying metal species and having an exposed surface. A mesh screen is maintained at a preset distance from the exposed surface, the mesh screen having a plurality of mesh openings. A process gas is energized to form a plasma by applying an electrical power to deposit the battery component material onto the exposed surface of the battery component layer. The mesh screen reduces migration of the charge-carrying metal species in the battery component layer to the exposed surface of the partially fabricated battery cell.
