  • Patent number: 9905851
    Abstract: Provided are a cathode active material including polycrystalline lithium manganese oxide and a boron-containing coating layer on a surface of the polycrystalline lithium manganese oxide, and a method preparing the same. Since the cathode active material according to an embodiment of the present invention may prevent direct contact between the polycrystalline lithium manganese oxide and an electrolyte solution by including the boron-containing coating layer on the surface of the polycrystalline lithium manganese oxide, the cathode active material may prevent side reactions between the cathode active material and the electrolyte solution. In addition, since limitations, such as the Jahn-Teller distortion and the dissolution of Mn2+, may be addressed by structurally stabilizing the polycrystalline lithium manganese oxide, tap density, life characteristics, and charge and discharge capacity characteristics of a secondary battery may be improved.

  • Patent number: 9780423
    Abstract: An air battery has a cathode layer, an anode layer and an electrolyte layer interposed between the cathode and anode layers. At least one of the cathode and anode layers has a passage forming member such that, when the air battery is adjacently stacked to another air battery, the passage forming member is situated between the air battery and the adjacent air battery so as to form an air passage to cathode layer. The passage forming member has conductivity and the ability to be elastically deformed according to expansion of the electrolyte layer. It is possible by this structure to, when there occurs increase in internal resistance due to expansion of the electrolyte layer, compensate such increase in internal resistance by decrease in contact resistance, maintain the cross-sectional area of the air passage at a predetermined size and prevent decrease in the output of the air battery.

  • Patent number: 9780404
    Abstract: The present invention relates to the application of a force to enhance the performance of an electrochemical cell. The force may comprise, in some instances, an anisotropic force with a component normal to an active surface of the anode of the electrochemical cell. In the embodiments described herein, electrochemical cells (e.g., rechargeable batteries) may undergo a charge/discharge cycle involving deposition of metal (e.g., lithium metal) on a surface of the anode upon charging and reaction of the metal on the anode surface, wherein the metal diffuses from the anode surface, upon discharging. The uniformity with which the metal is deposited on the anode may affect cell performance. For example, when lithium metal is redeposited on an anode, it may, in some cases, deposit unevenly forming a rough surface. The roughened surface may increase the amount of lithium metal available for undesired chemical reactions which may result in decreased cycling lifetime and/or poor cell performance.
