  • Patent number: 11600822
    Abstract: A cathode material and a fabricating method thereof, and a lithium-ion battery are described. The cathode material is a 1D metal-organic coordination polymer of [CuL(Py)2]n, and its structure is formed by interlinking organic ligands (L) and metals (Cu). The cathode material can use redox active sites on both the metal and organic ligand to carry out multi-electron transfer. A C?N bond contained in L together with a benzene ring of L in an adjacent polymer chain form a weak interaction of C?N . . . ?. In addition, a Py of adjacent polymer chains also have an interaction of ? . . . ?. Therefore, [CuL(Py)2]n chains are closely interlaced and packed, but there is still enough regular space for lithium ions to enter and exit quickly, so it can be charged and discharged rapidly and exhibits high power density.

  • Patent number: 7263468
    Abstract: A method of storing a data access record is described. The method of storing the records employs a micro control unit (MCU) to execute the control steps of the data access records and store the records in a non-volatile random access memory (NVRAM) in the network communication device. The boot timing is written in the NVRAM while a host system starts up and is used to login one or more client computer systems. The data access records are completely written in the NVRAM of the network communication device when the client computer systems are controlled by the host computer system. Additionally, the data access records stored in the NVRAM can be exported to a network attached storage (NAS) to expand the capacity of the NVRAM when the storage capacity for the data access records runs out or backup timing is due.
