  • Patent number: 9678880
    Abstract: A method and a system for cache management in system interfacing to a cloud storage. The cache has two layers: the filter layer for tracing read access to the data blocks and the cache layer for keeping the actual data blocks. The layer two consists of two modules—a main cache and a boot cache. The boot cache is filled during the short period of time after the first file open operation. The boot cache also has a limit on the amount of data that can be put into the cache for the particular file. The filter layer detects continuous read access pattern and avoids caching data, if the data is read continuously beyond some limit.

  • Publication number: 20090148773
    Abstract: An electrode, e.g. a negative electrode, for a lithium-ion battery cell is made from a carbonaceous material, such as a carbon paper, which is lithiated by direct contact with a piece of lithium metal in an atmosphere comprising carbon dioxide (CO2) gas. A method of making the electrode comprises the step of contacting tightly the carbonaceous material with the piece of lithium metal in the atmosphere. The method further comprises the step of storing the carbonaceous material and the piece of lithium metal in the atmosphere, and optionally, in an electrolyte, for a period of time sufficient to completely lithiate the carbonaceous material. A lithium-ion battery cell comprises the negative electrode, a positive electrode comprising oxides of a transition metal, and a non-aqueous electrolyte.

  • Publication number: 20090148769
    Abstract: The present invention provides a method of modifying a surface of a lithium electrode, e.g. a negative lithium electrode, for a battery cell. The method comprises the step of applying a thin layer of a carbonaceous material onto the surface of the lithium electrode. The method further comprises the step of applying a pressure to the thin layer and to the surface to promote tight contact between the surface and the thin layer. The method further comprises the step of storing the thin layer and the lithium electrode in an atmosphere comprising carbon dioxide (CO2) gas for a period of time sufficient to significantly lithiate carbon of the carbonaceous material into an intercalation compound having the formula LixC6. A battery cell, e.g. a secondary (rechargeable) battery cell, comprises the lithium electrode made by the method of the present invention.

  • Patent number: 7541016
    Abstract: A lithium titanate has the following formula: Li4Ti5O12?x wherein x is greater than 0. The lithium titanate is formed by providing a mixture of titanium dioxide and a lithium-based component. The mixture is sintered in a gaseous atmosphere comprising a reducing agent to form the lithium titanate having the above formula. A lithium-based cell includes an electrolyte, an anode, and a cathode, with at least one of the anode and the cathode comprising the lithium titanate having the above formula. The lithium titanate is deficient of oxygen, which increases electronic conductivity of the lithium titanate by at least three orders over electronic conductivity of a stoichiometric lithium titanate, while avoiding loss of reversible electric power-generating capacity that typically occurs when doping is used to replace titanium in the lithium titanate with atoms that provide higher electronic conductivity.
