Protective anode coatings for high energy batteries

Materials for coating a metal anode in a high energy battery, anodes coated with the materials, and batteries incorporating the coated anodes are provided. Also provided are batteries that utilize the materials as electrolytes. The coatings, which are composed of binary, ternary, and higher order metal and/or metalloid oxides, nitrides, fluorides, chlorides, bromides, sulfides, and carbides limit the reactions between the electrolyte and the metal anode in a battery, thereby improving the performance of the battery, relative to a battery that employs a bare anode.

In-situ polymerization to protect lithium metal electrodes

An electrode including an electrode active material including lithium (Li) and a polymer layer coating at least a portion of the electrode active material is provided. The polymer layer includes a polymerization product of a monomer having Formula I: where R1 and R2 are independently an aryl or a branched or unbranched C1-C10 alkyl and X1 and X2 are independently chlorine (Cl), bromine (Br), or iodine (I).

Method and apparatus for data protection in memory devices

An apparatus and method for efficiently transmitting data are described. A transmitter sends data to a receiver. An encoder of the transmitter divides a received first block of data into multiple sub-blocks. The encoder selects a portion of each sub-block to compare to one another. A portion in a particular sub-block has a same offset and a same size as other portions of other sub-blocks. If the encoder determines the multiple portions match one another, the encoder sends, to the receiver, a second block of data corresponding to the first block of data. The second block of data has a same size as a size of the received first block of data, and the second block of data includes security data from one of multiple error correction schemes. Therefore, the second block of data provides security without increasing an amount of data to transmit.
