Abstract: The present invention provides a one-sided electrode for a secondary battery comprising a current collector, an electrode mixture layer applied to one surface of the current collector, and an electrode distortion-preventing layer formed on the other surface of the current collector to which no electrode mixture is applied. The one-sided electrode according to the present invention exhibits significantly reduced warping or curling after a rolling process and has the advantages of facilitating subsequent processes and enabling enhanced productivity.

Abstract: The present invention relates to a non-aqueous electrolyte for a lithium secondary battery including a pyridine-boron-based compound as an additive and a lithium secondary battery including the same, and particularly, to a non-aqueous electrolyte including at least two types of lithium salts and a pyridine-boron-based compound and a lithium secondary battery which has an enhanced effect of suppressing an increase in resistance and generation of gas after being stored at high temperature by including both the non-aqueous electrolyte and a negative electrode including lithium titanium oxide (LTO) as a negative electrode active material.

Abstract: The present description relates to a fully biodegradable supercapacitor and a method for manufacturing the same. When the fully biodegradable supercapacitor and the method for manufacturing the same according to the present description are used, supercapacitor having high capacitance, high energy, and high output is provided by forming a metal oxide on a metal electrode and a surface of a solid electrolyte. In addition, the present description is environment-friendly, biodegradable, and biocompatible to be implanted into a body, and may be a bio-implantable energy storage device in the future.

Abstract: The present invention relates to a non-aqueous electrolyte for lithium secondary battery, and more particularly, to a non-aqueous electrolyte including a lithium salt having a concentration of 4.1 M or more, an organic solvent, and a surfactant.
