摘要： Rechargeable electrochemical cells that employ a highly conductive polymer-based solid gel membrane separator disposed between the anode and charging electrode are disclosed. The separator comprises a support or substrate and a polymeric gel composition having an ionic species contained in a solution phase thereof. In preparing the separator, the ionic species is added to a monomer solution prior to polymerization and remains embedded in the resulting polymer gel after polymerization. The ionic species behaves like a liquid electrolyte, while at the same time, the polymer-based solid gel membrane provides a smooth impenetrable surface that allows the exchange of ions for both discharging and charging of the cell. Advantageously, the separator reduces dendrite penetration and prevents the diffusion of reaction products such as metal oxide to remaining parts of the cell. Furthermore, the measured ionic conductivity of the separator is much higher than those of prior art solid electrolytes or electroyte-polymer films. The disclosed rechargeable electrochemical cells include, for example, metal/air, Zn/Ni, Zn/MnO2, Zn/AgO, Fe/Ni, and lead-acid systems.

摘要： An electrochemical cathode includes a porous metal foam substrate, formed with a network of interconnected pores. An active layer and a hydrophobic microporous gas diffusion layer are both disposed on one or more surfaces of the metal foam substrate. The metal foam substrate serves as the current collector of the cathode. The microporous layer is a plastic material such as a fluoropolymer (i.e., PTFE). The cathode also includes a particulate microstructure reinforced by relatively strong bonding provided by sintering a polymeric binder within the three-dimensional interconnected porosity of the metal foam substrate. The reactive layers are preferably fabricated from the same material as binder. This advantageously enables a single roll pressing operation to simultaneously impregnate the binder into the substrate and form the reactive layers thereon.

摘要： A fuel cell battery having an electrolyte, and a moving anode having anode material deposited on two sides of an electrically conductive substrate, which can be either a rotating anode disk, or a linearly moving anode, sandwiched between two air electrodes wherein the air electrodes each have at least one recharging portion and at least one discharging portion. The recharging portion of the air electrode is designed for optimum recharging and the discharging portion of the air electrode is designed for optimum discharging such that the fuel cell battery performs to its maximum ability. The recharging air electrode area can be larger than the discharging air electrode area for faster recharge times. The recharging air electrode can be operated at lower current densities to prevent anode densification, anode shape change and dendrite growth. Discharging the anode material on both sides of the anode increases the depth of the discharge and increases the battery's capacity. The anode movement assures the anode is intermittently discharged to reduce passivation and further increase the depth of discharge. The motion of the anode helps to insure uniform replating during recharging. Further, the movement of the anode stirs the electrolyte assuring a uniform distribution of metal ions. As a result, the invention provides a metal/air Fuel Cell Battery with high energy density high power density and good rechargeability.

摘要： A nickel-zinc electrochemical cell is disclosed using a polymer matrix separator. The polymer matrix separator includes a polymerization product of one or more monomers selected from the group of water-soluble, ethylenically-unsaturated acids and acid derivatives, and a crosslinking agent, and serves as a primary or supplemental source of electrolyte ionic species for the electrochemistry. Ionic species is contained as a solution phase within the polymer matrix membrane, allowing it to behave as a liquid electrolyte without the disadvantages. In secondary batteries (i.e., rechargeable), polymer matrix membranes are particularly useful as both an electrolyte reservoir and as a dendrite resistant separator between the charging electrode and the zinc electrode. The polymer matrix membrane protects the electrodes from corrosion and prevents zinc oxidation product from the zinc electrode to contaminate the electrolyte.

摘要： A metal air cell system comprises a frame structure configured with variable airflow paths. The variable airflow paths provide alternatives between direct open loop airflow and semi-closed loop air flow, wherein air is at least partially circulated around the cell components. This is particularly useful for operation in different temperature environments. The open loop mode is useful for high temperature environments, and the semi-closed loop mode is useful for low temperature environments.
