摘要： An alloy anode for a seawater based aqueous battery and a universal strategy for preparing anodes for use in seawater based aqueous batteries. Zn-M alloys (where M can be manganese or other transition metal) were prepared by co-electrodeposition in the presence of hydrogen bubble formation to produce a porous nanostructured alloy that can serve as an anode for a seawater based aqueous battery. Exemplary Zn—Mn alloy anodes achieved stability over thousands of cycles even under harsh electrochemical conditions, including testing in seawater-based aqueous electrolytes and using a high current density of 80 mA cm−2. The anode design strategy allows for the production of durable electrodes for aqueous batteries and other applications.

摘要： The fabrication method of a lithium microbattery provides for use of a substrate successively covered by: a cathode, a solid electrolyte, and a first electrically conducting layer made from a material configured to combine with the lithium atoms. The first layer is devoid of contact with the cathode. The method further includes formation of a second electrically conducting layer configured to form a diffusion barrier for the lithium atoms. The second layer is electrically connected to the first layer and leaves at least a part of the first layer uncovered, the part being facing the electrolyte. Electrochemical deposition of a lithium anode is then performed from germination from the first and second electrically conducting layers.

摘要： The present invention is directed to battery system and operation thereof. In an embodiment, lithium material is plated onto the anode region of a lithium secondary battery cell by a pulsed current. The pulse current may have both positive and negative polarity. One of the polarities causes lithium material to plate onto the anode region, and the opposite polarity causes lithium dendrites to be removed. There are other embodiments as well.
