Abstract: Cathodes and lithium secondary batteries including the cathodes are disclosed. In some implementations, a cathode may include a cathode current collector and a cathode active material layer disposed on the cathode current collector and including cathode active material particles such that the cathode active material layer satisfies a specific equation. The cathode active material particles may include lithium metal oxide particles that include nickel, and may have a mole fraction of cobalt of 0.02 or less with respect to all elements except for lithium and oxygen.

Abstract: A cathode for a lithium secondary battery includes a cathode current collector, and a cathode active material layer formed on the cathode current collector. The cathode active material layer includes a cathode active material and a conductive material ID/IG is in a range from 0.5 to 1.25 in a Raman spectrum of the cathode active material layer. The cathode active material includes lithium metal oxide particles containing nickel and manganese and having a content of cobalt of less than 2 mol % among all elements except for lithium and oxygen.

Abstract: The present disclosure relates to an offset elimination operation of an internal operational amplifier of a data driving circuit and relates to a technique that applies different offset elimination methods for each position of an operational amplifier.

Abstract: A mobile terminal and method for controlling place recognition are provided. The method includes collecting at least one of state information about a mobile terminal and user information stored in the mobile terminal, determining whether a current place of the mobile terminal is a major place that the user has previously visited at least a number of times using the collected information, determining, if it is determined that the current place of the mobile terminal is a major place, whether the current place has been registered using at least one signal received externally, and outputting a result of the determination as to whether the current place has been registered.
