Characteristics and development of vanadium phosphate lithium ion battery

In the early 1970s, the research work of lithium-ion batteries was promoted due to the energy crisis, and lithium primary batteries with Li or Li-Al alloy as negative electrode materials, including Li/MnO2, Li/I2, Li/SOCl2, Li/FeS2, etc., appeared one after another. In 1970, Japan’s panasonic company obtained a patent for Li/(CF)n batteries in the United States, and during the discharge process (CF)n was lithiated into C and LiF, and the reaction was not reversible, so the lithium primary battery at [...]

CeB6 cerium boride application in various industries

CeB6 cerium boride is a typical hexaboride, which has high melting point, high hardness, low escape work, good chemical stability, strong ion bombardment resistance, high electrical conductivity (its electrical resistivity is similar to rare earth metals) and other excellent properties, so it is widely used in various fields In the field of electronics industry, CeB6 cerium boride is an ideal hot cathode material, which is widely used in high-brightness point-like electron source equipment, such as SEM, TEM and other electron [...]

Study on nanometer nickel hydroxide electrode materials

Nickel metal hydride batteries (MH-Ni) with high specific energy and excellent performance are widely used in electronics, communications, computers and other industries, and will also be widely used in the field of electric vehicles. As a positive active substance, the performance of nickel hydroxide is the key to determine the overall performance of MH-Ni batteries. In this paper, nanometer nickel hydroxide is studied comprehensively from the following four aspects: First, nanometer nickel hydroxide is prepared by grinding micron grade [...]

Adsorption of low concentration phosphate in water by lanthanum hydroxide and natural zeolite

Zeolite is a porous aluminosilicate crystal with skeleton structure, which has high cation exchange ability. In recent years, the use of cation exchange capacity of zeolite to remove ammonia nitrogen from water has attracted the attention of many researchers. The surface of zeolite aluminosilicate skeleton is negatively charged, so the adsorption ability of zeolite to phosphoric acid anion in water is very poor. In order to improve the adsorption capacity of phosphate in water, it is necessary to properly [...]
