Abstract: The present invention aims to provide a lithium ion secondary cell configured to be charged by light such as solar light (particularly, UV light (for example, light having a wavelength of 350 nm to 400 nm)). The present invention relates to a lithium ion secondary cell including: a pair of substrates, at least one of the substrates being light transmitting; an electrolyte filled between the pair of substrates; a positive electrode that includes a positive electrode material selected from lithium-containing metal oxides and that is disposed to contact the electrolyte; and a negative electrode that includes a negative electrode material selected from n-type semiconductor materials and that is disposed to contact the electrolyte.
Abstract: Provided is a metal colloid having higher visibility and higher sensitivity than a gold colloid and a Au-core Pt-shell composite colloid and suitable as a labeling agent for use in a test such as an immunoassay. An alloyed Au/Pt composite colloid formed by mixing a gold salt and a platinum salt with at least one reducing agent selected from the group consisting of an amino acid and a derivative thereof, an oligopeptide and a derivative thereof, and an amino sugar in the presence of an alkali, thereby reducing the gold salt and platinum salt.
