Abstract: A power storage module comprises an electrode assembly including a plurality of electrode plates stacked in a stacking direction, a resin sealing body for sealing an internal space formed between two adjacent electrode plates of the plurality of electrode plates, and a terminal member provided to the electrode assembly so as to protrude from the resin sealing body toward outside, wherein the terminal member is provided with one or more through holes penetrating along the stacking direction.

Abstract: Provided are an electrolytic solution suitable for a lithium ion secondary battery that includes a positive electrode which has a positive electrode active material having an olivine structure, and includes a negative electrode having graphite as a negative electrode active material, and a superior lithium ion secondary battery having the electrolytic solution. The lithium ion secondary battery includes: a positive electrode that includes a positive electrode active material having an olivine structure; a negative electrode having graphite as a negative electrode active material; and an electrolytic solution. The electrolytic solution contains LiPF6, a cyclic alkylene carbonate selected from ethylene carbonate and propylene carbonate, methyl propionate, and an additive that starts reductive degradation at a potential higher than a potential at which the above components of the electrolytic solution start reductive degradation.

Abstract: An additive for a lithographic dampening solution is disclosed, which comprises:(a) a compound represented by the following formula (A): ##STR1## wherein R represents a methyl group, an ethyl group, an n-propyl group or an isopropyl group, and n represents an integer of 1 to 4; and(b) an alcohol having an HLB of 7.0 to 15.0 which is selected from the group consisting of primary or tertiary alkoxyalcohols having an alkoxy group containing from 1 to 6 carbon atoms, primary or tertiary alkanols, saturated straight-chain polyhydric alcohols containing from 2 to 6 carbon atoms and diethylene glycol monoalkyl ethers. A dampening solution for lithographic printing comprising water and the additive is also disclosed.
