Abstract:
A cable-type secondary battery is disclosed. The cable-type secondary battery includes electrodes, each of which includes a current collector having a horizontal cross section of a predetermined shape and an active material layer formed on the surface of the current collector. The electrodes extend in the lengthwise direction and are arranged in parallel. The current collector includes a polymer core and a metal coating layer formed on the surface of the polymer core. The use of the metal-coated polymer current collectors having high flexibility and conductivity makes the secondary battery highly flexible while maintaining the performance of the secondary battery. In addition, the cable-type secondary battery can be reduced in weight.
Abstract:
Provided is a cable-type secondary battery including at least one anode extending longitudinally and having a horizontal cross section of a predetermined shape, a first electrolyte layer surrounding the anode and serving as an ion channel, at least one cathode extending longitudinally and having a horizontal cross section of a predetermined shape, the anode and the cathode arranged in parallel, a second electrolyte layer serving as an ion channel commonly surrounding the anode and the cathode, and a protection coating surrounding the second electrolyte layer. The cable-type secondary battery has free shape adaptation due to its linearity and flexibility. Introduction of the electrolyte layer on the electrode prevents a short circuit. The presence of a plurality of electrodes leads to an increased contact area therebetween and consequently a high battery rate. By adjusting the number of the anodes and the cathodes, it is easy to control the capacity balance therebetween.

Abstract:
Provided are a simplified 4:2 carry save adder (CSA) cell and a 4:2 carry save adding method. The 4:2 CSA cell is formed of an odd detector and first through sixth switches through logic optimization. The odd detector generates an XOR of the first through fourth input signals, outputs the XOR as an odd signal, generates an XOR of the first and second input signals, and outputs the XOR as a first XOR signal. The first switch outputs the third input signal as a carry output signal in response to the first XOR signal. The second switch outputs the first input signal as the carry output signal in response to an inverted first XOR signal. The third switch outputs the carry input signal as a carry signal in response to the odd signal. The fourth switch outputs the fourth input signal as the carry signal in response to an inverted odd signal. The fifth switch outputs an inverted carry input signal as a sum signal in response to the odd signal. The sixth switch outputs the carry input signal as the sum signal in response to the inverted odd signal.
Abstract:
The present invention relates to a cable-type secondary battery comprising an inner electrode comprising at least two anodes arranged in parallel, the anode extending longitudinally and having a horizontal cross section of a predetermined shape, the anode having an electrolyte layer thereon serving as an ion channel; an outer electrode comprising a cathode including a cathode active material layer surrounding the inner electrode; and a protection coating surrounding the outer electrode. The cable-type secondary battery has free shape adaptation due to its linearity and flexibility. A plurality of inner electrodes within a tubular outer electrode lead to an increased contact area therebetween and consequently a high battery rate. It is easy to control the capacity balance between the inner and outer electrodes by adjusting the number of inner electrodes. A short circuit is prevented due to the electrolyte layer formed on the inner electrode.
