Appl. No.:

11/533268

Inventors:

Thomas Lin - Rancho Palos Verdes CA, US
Larisa Malinovskaya - Torrance CA, US
Jun Chen - Redondo Beach CA, US

International Classification:

H01M 10/04
B23P 19/00

US Classification:

296231, 29730

Abstract:

A lithium-ion polymer battery, and methods and apparatus for manufacturing the same, are disclosed. The methods include forming an anode with a porous material having spaces that contain an electrolytic solution, placing the anode surface in contact with a layer of lithium metal, and shorting the layer of lithium metal to a current collector so that lithium ions are released from the layer of lithium metal and forming SEI layer on the anode surface through the reaction with the electrolyte reduction products.

Abstract:

A lithium-ion polymer battery and method and apparatus for manufacturing the same, are disclosed. The battery includes an anode comprising a first electrolytic solution and a cathode comprising a second electrolytic solution, and the first and second electrolytic solutions are different. The method includes activating the anode and the cathode in the different electrolytic solutions prior to battery assembly and prior to forming an SEI layer on the anode surface.

Inventors:

Thomas Lin - Rancho Palos Verdes CA, US
Larisa Malinovskaya - Torrance CA, US
Jun Chen - Redondo Beach CA, US

International Classification:

H01M 6/24

US Classification:

429101, 296235

Abstract:

A lithium-ion polymer battery, and methods and apparatus for manufacturing the same, are disclosed. The methods and apparatus include forming electrodes with porous material that have spaces, filling substantially all of the spaces in the electrodes with liquid and, after filling the spaces with liquid, forming an electrolyte polymer film on the electrode.

International Classification:

H01M 10/04
B23P 19/00

US Classification:

429162, 296235, 29730

Abstract:

A lithium-ion polymer battery, and methods and apparatus for manufacturing the same, are disclosed. The methods include placing a bottom surface of an electrode on a coating surface, such that a top surface of the electrode is exposed, forming a removable retention boundary on the coating surface and surrounding the electrode, including a space between the electrode edges and the retention boundary, depositing polymer electrolyte solution on the electrode, on the coating surface, and within the retention boundary, and allowing the polymer electrolyte solution to dry until all of the deposited polymer electrolyte solution becomes a solid polymer composite that extends beyond the electrode edges.

International Classification:

A61F 2/04
A61F 2/95

Abstract:

One aspect of the invention provides a removable ureteral stent including: an elongated stent with opposing curls at either end; a coil of memory material attached to a curl at one end of the stent that can uncoil and elongate under tensile force, and does so elongate and uncoil at a lower tensile force than that needed to induce substantial uncoiling of either curl, and wherein the coil is at least long enough such that its distal end (from the end attached to the stent) can pass through an internal urethral sphincter, when the stent is in place in the ureter; and a magnet attached to the distal end of the coil.
