A molybdenum sulfide powder according to the invention contains molybdenum disulfide having a 3R crystal structure. A heavy-metal adsorbent according to the invention contains molybdenum sulfide particles, and the molybdenum sulfide particles have a median diameter Dof 10 nm to 1,000 nm obtained by a dynamic light scattering type particle diameter distribution measuring device. A photothermal conversion material according to the invention contains a material containing molybdenum sulfide particles and generates heat by absorbing light energy.

Molybdenum sulfide powder and method for producing same, heavy-metal adsorbent, photothermal conversion material, distillation method, oxygen reduction catalyst, and catalyst ink

The invention provides a packaging material that has high formability and that does not undergo a decrease in the adhesion strength between layers and appearance defects such as lifting between layers even after thermal fusion between portions of the sealant layer performed for sealing battery elements and furthermore after a long-term durability test under high temperature and high humidity. The adhesive for the packaging material including, as essential components, a polyol composition (A) and a polyisocyanate composition (B), wherein the polyol composition (A) includes a polyester polyol made from, as essential materials, a polybasic acid or its derivative and a polyhydric alcohol, the polybasic acid or its derivative material is all an aromatic-ring-containing polybasic acid or its derivative, and the polyester polyol has a number-average molecular weight in a range of 3000 to 100000; a battery packaging material, a battery container, and a battery that use the adhesive.
