Abstract: A method for producing an ion-exchange resin having a water content of 5% by weight or less, a method for producing a lithography coating film forming-composition using the ion-exchange resin, and a method for washing the ion-exchange resin. The methods include the step of passing an organic solvent having a water content of 150 ppm or less through an ion-exchange resin precursor having a water content of 40% by weight or more, where a dehydration efficiency defined by the following equation is 5 or more: Dehydration efficiency=Dehydration rate (%)/[Weight of the organic solvent used per unit weight of the ion-exchange resin precursor (kg/kg)×Washing time (h)].

Abstract: A purification method for a silicon-containing polymer composition capable of reducing metal impurities in a silicon-containing polymer composition to be treated, while suppressing the weight average molecular weight change before and after the treatment, by treating the silicon-containing polymer composition containing the metal impurities with an ion exchange resin having a specific structure; a silicon-containing polymer composition; and a method for producing a semiconductor device. A purification method for a silicon-containing polymer composition reduced in weight average molecular weight change before and after treatment, said method being treating a silicon-containing polymer composition to be treated containing an organic solvent with an gel-type cation exchange resin. The weight average molecular weight change before and after the treatment is 70 or less. The ion exchange resin preferably has a strongly acidic functional group.

Abstract: In this assembled battery, connections between electrode terminals of electrical cells and connection members for the electrode terminal are reliably maintained for a long period of time. The electrode terminal is formed in a tapered pillar shape whose width decreases from the front end of the electrode terminal toward a battery case. Also, a groove, which is shaped from the front end toward the battery case and divides at least a portion of the front end into segmented portions, is provided to the electrode terminal. The segmented portions are elastically deformable to move close to or away from each other. The bus bar (connection member for the electrode terminals) includes a through-hole whose width decreases from the front end of the electrode terminal toward a battery case. The bus bar is fitted to the electrical terminal, by elastically deforming and moving the segmented portions close to each other.

Abstract: A battery system comprises a first battery cell and a first management unit which is connected in one-to-one correspondence to the first battery cell. The first management unit comprises a first parameter acquiring unit, a first calculating unit, and a first storage unit. The first parameter acquiring unit acquires a power consumption parameter of the first battery cell. The first calculating unit calculates a power consumption state value of the first battery cell on the basis of the power consumption parameter acquired by the first parameter acquiring unit. The first storage unit stores the power consumption state value calculated by the first calculating unit.
