Provided is a low-density parity-check (LDPC) code decoder and a decoding method. The decoding method may include calculating a message of a variable node (V-node), calculating a message of a check node (C-node), and calculating log-likelihood ratio (LLR) data of a channel using the message of the V-node and the message of the C-node.

Disclosed herein is a wireless charging system that includes a transmission device including a primary coil and a reception device including a secondary coil, wherein the transmission device detects an input signal provided from the primary coil to generate an output signal in the form of a pulse, and compares the level of the generated output signal with a reference voltage to generate a detection signal for determining the presence or absence of the reception device. The wireless charging system does not require an analog-to-digital converter (ADC), eliminating the necessity of using an ADC chip or a high-priced control circuit including an ADC block, thus reducing a material cost of the system. In addition, since the wireless charging system does not require a software algorithm for processing an ADC signal, the performance can be improved.

A high capacity lithium secondary battery includes a lithium manganese oxide having a layered structure exhibiting a great irreversible capacity in the event of overcharging at a high voltage and a spinel-based lithium manganese oxide. Because it is activated at a high voltage of 4.45 V or higher based on a positive electrode potential, additional lithium for utilizing a 3V range of the spinel-based lithium manganese oxide can be provided and an even profile in the entire SOC area can be obtained. Because the lithium secondary battery includes the mixed positive electrode active material including the spinel-based lithium manganese oxide and the lithium manganese oxide having a layered structure, and is charged at a high voltage, its stability can be improved. Also, the high capacity battery having a large available SOC area and improved stability without causing an output shortage due to a rapid voltage drop in the SOC area can be implemented.
