摘要： Disclosed is a non-aqueous electrolyte including an electrolyte salt and an electrolyte solvent, the non-aqueous electrolyte further including a compound containing both a carboxy group and a (meth)acrylic group, and a secondary battery including the non-aqueous electrolyte. The use of the compound containing both the carboxy group and the (meth)acrylic group as a component for an electrolyte significantly reduces the increase of battery thickness at high temperature storage.

摘要： A negative active material for a lithium secondary battery which is capable of improving packing density and has good high-rate charge/discharge and cycle life characteristics is provided. The negative active material includes a crystalline carbon core and an amorphous carbon shell. Alternatively, the negative active material includes secondary particles prepared by gathering at least one crystalline carbon primary particle. A surface of the secondary particles is coated with an amorphous carbon and the secondary particles has a substantially spherical form. The negative active material has two exothermic peak of the differential thermal analysis at 1000° C. or less. A lithium secondary battery using the negative active material can use propylene carbonate for an organic solvent of an electrolyte.
