摘要:
A shunt regulator includes a control circuit, a bypass circuit and a protection circuit. The control circuit is coupled between a first node and a ground, and generates a gate control signal in response to a voltage of the first node and a reference voltage. The bypass circuit forms a first current path between the first node and the ground in response to the gate control signal. The protection circuit has an MOS transistor that is fully turned on in response to a current flowing through the bypass circuit, and forms a second current path between the first node and the ground. Therefore, the shunt regulator occupies a relatively small area in an integrated circuit.

An organic electrolytic solution and a lithium battery employing the same are provided. The organic electrolytic solution includes: a lithium salt; an organic solvent containing a high dielectric constant solvent and a low boiling point solvent; and a carbonate or oxalate derivative having at least one substituted or unsubstituted cyano group. The organic electrolytic solution and the lithium battery employing the same have improved reductive decomposition stability, thereby decreasing an irreversible capacity after a first cycle and improving the charge/discharge efficiency and lifespan of the battery. The lithium battery has non-varying chemical properties at room temperature and a uniform thickness after standard charging, and thus has high reliability.

The present invention is related to a negative electrode for a lithium secondary battery, a method of manufacturing the same, and a lithium secondary battery containing the negative electrode. In particular, the negative electrode of the present invention has improved initial charge/discharge efficiency, and increased lifespan by limiting the swelling of a lithium alloy-based active material. The negative electrode comprises a negative active material layer, comprising a lithium alloy-based negative active material, formed on a current collector, where the surface of the negative active material layer is coated with a polymer film formed from a solution mixture of a crosslinking monomer with ionic conductivity and low electric conductivity, a polymer support, and an organic solvent, and the negative active material layer includes cavities filled with crosslinking monomers that are cross-linked with one another.
