Abstract: Provided is a method of producing carbon particles for an electrode, each containing particles of a metal capable of forming an alloy with lithium, being formed by an aggregation of numerous fine particles composed of carbon, and having a hollow open-cell structure in which cells among the fine particles form a plurality of interconnected pores. The method includes mixing together a monomer having a low compatibility with a polymer to be formed, an organic solvent having a low compatibility with the polymer to be formed, and particles of a metal capable of forming an alloy with lithium, to prepare a monomer-containing mixture; dispersing the monomer-containing mixture in an aqueous phase to prepare a suspension containing, dispersed therein, oil droplets of the monomer-containing mixture; polymerizing the oil droplets in the suspension to prepare resin particles; and curing the resin particles. The carbon particles find use for negative-electrode in lithium-ion secondary batteries.

Abstract: Materials and methods of synthesizing mixed-layered bismuth oxy-iodine materials, which can be synthesized in the presence of aqueous radioactive iodine species found in caustic solutions (e.g. NaOH or KOH). This technology provides a one-step process for both iodine sequestration and storage from nuclear fuel cycles. It results in materials that will be durable for repository conditions much like those found in Waste Isolation Pilot Plant (WIPP) and estimated for Yucca Mountain (YMP). By controlled reactant concentrations, optimized compositions of these mixed-layered bismuth oxy-iodine inorganic materials are produced that have both a high iodine weight percentage and a low solubility in groundwater environments.
