An electrochemical cell including a getter material, a battery including the electrochemical cell, and methods of forming the electrochemical cell and battery are disclosed.

Getter for use with electrochemical cells, devices including the getter, and method of forming same

An electrolyte, an electrochemical cell including the electrolyte, and a battery including the electrochemical cell are disclosed. Exemplary electrolytes allow for electrochemical cells and batteries with relatively high efficiency and stability that can be charged to relatively high voltages.

Electrochemical cell and electrolyte for same

A rechargeable battery with elastically compliant housing includes a housing and at least one battery cell. The housing includes a pair of substantially rigid end plates and an elastically compliant structure joining the end plates so that the end plates are oriented in respective planes that are substantially parallel to each other and define a gap there between. Each battery cell is contained in the housing in the gap between the end plates and includes an anode, a cathode, and a separator between the anode and the cathode. The elastically compliant structure joins the end plates and includes an elastic component that exhibits elastic expansion greater than 3% along an axis orthogonal to the planes in which the end plates are oriented.

Electrolytes for use in commercially viable, rechargeable lithium metal batteries are described. The electrolytes contain one or more lithium salts, one or more organic solvents, and one or more additives. The electrolytes allow for reversible deposition and dissolution of lithium metal. Specific additives or additive combinations dramatically improved cycle life, decrease cell swelling, and/or lower cell impedance.

Additive containing electrolytes for high energy rechargeable metal anode batteries

A secondary cell comprising a positive cathode electrode of capacity P (mAh) in communication with a liquid or gel electrolyte; an negative anode electrode of capacity N (mAh) in communication with the electrolyte; and a separator permeable to at least one mobile species which is redox-active at least one of the anode and the cathode; designed and constructed such that the anode capacity N is smaller than that of the cathode capacity P, hence N/P&#x3c;0.9.

Electrochemical cell and method of making the same

A multi-electrode device that includes an anode electrode, a cathode electrode, and a gate electrode situated between the anode and cathode, and having an electrolyte. The multi-electrode device can be a secondary (rechargeable) electrochemical cell. The gate electrode is permeable to at least one mobile species which is redox-active at at least one of the anode and cathode. The gate electrode has a resistance that is lower than that of a conductive non-uniform morphological feature that could be grown on the anode. The gate electrode provides the ability to avoid, recognize, and remove the presence of such non-uniform morphological features, and provides an electrical electrode that can be used to remove such non-uniform morphological features.

A non-aqueous Magnesium electrolyte comprising: (a) at least one organic solvent; (b) at least one electrolytically active, soluble, inorganic Magnesium (Mg) salt complex represented by the formula: MgZXwherein a, b, and c are selected to maintain neutral charge of the molecule, and Z and X are selected such that Z and X form a Lewis Acid, and 1&#x2266;a&#x2266;10, 1&#x2266;b&#x2266;5, and 2&#x2266;c&#x2266;30. Further Z is selected from a group consisting of aluminum, boron, phosphorus, titanium, iron, and antimony; X is selected from the group consisting of I, Br, Cl, F and mixtures thereof.

Electrochemical devices which incorporate cathode materials that include layered crystalline compounds for which a structural modification has been achieved which increases the diffusion rate of multi-valent ions into and out of the cathode materials. Examples in which the layer spacing of the layered electrode materials is modified to have a specific spacing range such that the spacing is optimal for diffusion of magnesium ions are presented. An electrochemical cell comprised of a positive intercalation electrode, a negative metal electrode, and a separator impregnated with a nonaqueous electrolyte solution containing multi-valent ions and arranged between the positive electrode and the negative electrode active material is described.

A rechargable magnesium battery having an non-aqueous electrolyte is provided. The properties of the electrolyte include high conductivity, high Coulombic efficiency, and an electrochemical window that can exceed 3.5 V vs. Mg/Mg. The use of the electrolyte promotes the electrochemical deposition and dissolution of Mg without the use of any Grignard reagents, other organometallic materials, tetraphenyl borate, or tetrachloroaluminate derived anions. Other Mg-containing electrolyte systems that are expected to be suitable for use in secondary batteries are also described.
