摘要:
The present invention includes substantially single-phase lithium metal oxide compounds having hexagonal layered crystal structures that are substantially free of localized cubic spinel-like structural phases. The lithium metal oxides of the invention have the formula Li&agr;M&bgr;A&ggr;O2, wherein M is one or more transition metals, A is one or more dopants having an average oxidation state N such that +2.5≦N≦+3.5, 0.90≦&agr;≦1.10, and &bgr;+&ggr;=1. The present invention also includes dilithiated forms of these compounds, lithium and lithium-ion secondary batteries using these compounds as positive electrode materials, and methods of preparing these compounds.
摘要:
The present invention is a method for the detoxification and/or chemical remediation of soil contaminated with volatile organic compounds. The process comprises treating the soil with the sodium and calcium salts of naphthalene sulfonates, lignosulfonates, their derivatives and mixtures thereof. The volatile organics are then forced from the soil as the soil is more attracted to the admixture than it is to the volatile organic contaminants.
