A lithium-ion battery comprising a first electrode made of cathodic material, a second electrode made of anodic material and an electrolyte, said lithium-ion battery containing an overcharge protection material consisting of redox molecules, characterized by the fact that said redox molecules have a reduction potential which is lower than said anodic material.

Disclosed is a presensitized plate composed of a support having thereon an image recording layer which includes:an infrared absorber (A) that is a cyanine dye having at least one fused ring composed of a nitrogen-containing heterocycle in combination with an aromatic ring or a second heterocycle, and having on the aromatic ring or second heterocycle an electron-withdrawing group or a heavy atom-containing group,a radical generator (B), anda radical-polymerizable compound (C),and which is removable with printing ink and / or dampening water.The presensitized of the present invention can be imaged with an infrared light-emitting laser to directly record an image from digital data on a computer or the like and is then subjected to on-machine development without carrying out a development step, which is capable of providing a large number of good impressions with a practical amount of energy.

A positive electrode includes first positive electrode active material particles and second positive electrode active material particles. The first positive electrode active material particles include 0.1% by mass or more and 1% by mass or less of lithium carbonate and a first lithium transition metal oxide as a remainder. The first lithium transition metal oxide is represented by LiM1(1-z1)Mnz1O2 (0.05≤z1≤0.20). The second positive electrode active material particles include 0.01% by mass or more and 0.05% by mass or less of lithium carbonate and a second lithium transition metal oxide as a remainder. The second lithium transition metal oxide is represented by LiM2(1-z2)Mnz2O2 (0.40≤z2≤0.60). An electrolytic solution includes 1% by mass or more and 5% by mass or less of an overcharging additive and a solvent and a lithium salt as a remainder.

Disclosed are a non-aqueous electrolyte solution for a lithium secondary battery and a lithium secondary battery comprising the same. The non-aqueous electrolyte solution for a lithium secondary battery may include difluorotoluene having a lowest oxidation potential among components of the non-aqueous electrolyte solution. The lithium secondary battery may have improvement in basic performance including high rate charge / discharge characteristics, cycle life characteristics, and the like, and may remarkably reduce swelling caused by decomposition of an electrolyte solution under high voltage conditions such as overcharge.
