摘要:
An electrolyte solution and a battery which are capable of improving cycle characteristics are provided. An anode includes a simple substance, an alloy or a compound of a metal element or a metalloid element capable of forming an alloy with lithium as an anode active material. A separator is impregnated with an electrolyte solution formed through dissolving an electrolyte salt in a solvent. The electrolyte salt includes a first electrolyte salt including LiB(C2O4)2 and a second electrolyte salt including at least one kind selected from the group consisting of LiPF6, LiBF4, LiN(CF3SO2)2, LiN(C2F5SO2)2, LiClO4, LiAsF6 and LiC(CF3SO2)3. In the solvent, 4-fluoroethylene carbonate is included. A coating is formed on the anode by the first electrolyte salt, and high ionic conductivity can be obtained by the second electrolyte salt. Further an oxidation-decomposition reaction of the electrolyte solution which occurs in a cathode can be prevented by 4-fluoroethylene carbonate.

摘要:
The present invention uses a mixture of spherical carbonaceous materials having different average particle sizes as an anode active material in an anode composite mixture layer of an anode. The spherical carbonaceous material of large particle size decreases the reaction with non-aqueous electrolyte solution to suppress the decrease in battery capacity, form clearances having suitable sizes in the anode composite mixture layer, and retain the non-aqueous electrolyte solution. The clearances in the anode composite mixture layer are efficiently filled with the carbonaceous material of small particle size while spaces capable of suitably retaining the non-aqueous electrolyte solution are left unfilled. Thus, the volume density of the anode composite mixture layer is improved and the battery capacity is increased. Accordingly, energy density can be increased without deteriorating battery characteristics.
摘要:
The invention provides an electrolyte whose battery capacity, cycle characteristics, load characteristics, and low temperature characteristics are all excellent, and a battery using it. A cathode and an anode are layered and wound with a separator and electrolyte layer in between. The electrolyte layer contains a high molecular weight compound and an electrolytic solution containing at least one from the group consisting of vinylethylene carbonate and its derivatives in the range of 0.05 wt % to 5 wt % in total. Therefore, chemical stability of the electrolyte layer is improved. It is preferable that the electrolytic solution further contains ethylene carbonate and propylene carbonate by a mass ratio of ethylene carbonate:propylene carbonate=15-75:85-25.

An electrolyte whose battery capacity, cycle characteristics, load characteristics, and low temperature characteristics are all excellent, and a battery using it. A cathode and an anode are layered and wound with a separator and electrolyte layer in between. The electrolyte layer contains an electrolytic solution containing at least one from the group consisting of vinylethylene carbonate and its derivatives in the range of 0.05 wt % to 5 wt % in total and a polymer. Therefore, chemical stability of the electrolyte layer is improved. It is preferable that the electrolytic solution further contains ethylene carbonate and propylene carbonate with a mass ratio of ethylene carbonate to propylene carbonate ranging from about 15/85 to about 75/25.
