The electric tool includes a lithium-ion secondary battery as a power supply, and is equipped with an electrical device, which operates on small electric power supplied from the lithium-ion secondary battery.
摘要:
A method for manufacturing a battery electrode plate includes the steps of mixing a solvent (3) with a polyolefin resin (1); preparing a gel-like solution (5), a gelled solution as a whole having a high viscosity, by heating the mixture of the polyolefin and the solvent at a temperature at which a part or the whole of the polyolefin resin melts; forming an insulation layer (8) by coating the gel-like solution on the surface of the positive electrode plate or negative electrode plate (7); and heating the positive electrode plate or negative electrode plate formed with the insulation layer.
摘要:
According to a deterioration detecting method for rechargeable lithium batteries, battery voltages of a rechargeable lithium battery before and after the completion of charging or discharging are measured. An evaluation value is calculated based on the measured battery voltages. This evaluation value is compared with a reference value of the rechargeable lithium battery stored in advance. A deterioration level of the rechargeable lithium battery is estimated based on this comparison result. In addition, further deterioration can be suppressed by controlling charging and discharging of the rechargeable lithium battery based on the estimated deterioration level.

A method for manufacturing a cell electrode plate comprising: the step of mixing a polyolefin resin (1) with a solvent (3); the step of preparing a gel solution (5) having a totally high viscosity by heating the mixture of the polyolefin resin and the solvent at a temperature to melt the polyolefin resin partially or totally; the step of forming an insulating layer (8) by applying the gel solution to the surface of an anode or cathode (7); and the step of heating the anode or cathode having the insulating layer formed thereon.
摘要:
A non-aqueous electrolyte secondary battery using lithium containing composite oxide, which intercalates and de-intercalates lithium, for a positive electrode; and lithium containing composite nitride and a compound having a large irreversible capacity for a negative electrode. Metal oxide is used as a material for the negative electrode, and lithium containing composite nitride represented by the general formula of Li 3-x M x N (M is a transition metal, 0.2 2 O 4 ) may be used. High capacity and high quality non-aqueous electrolyte secondary battery with good cycle reversibility may be obtained by adding lithium containing composite nitride to the negative electrode.
