新能源汽车动力型锂离子电池锰酸锂正极材料循环性能的改性

在目前主流的锂离子正极材料中，尖晶石锰酸锂(LiMn₂O₄)具有成本低廉与安全性能高的优势，因此在小型新能源汽车领域有广泛的应用。目前锰酸锂正极材料发展与应用的主要障碍在于锰元素的溶解。锰的溶解将导致循环性能的迅速衰退，在高温循环中尤为显著。在实验中，以氟化锂作为包覆物质，将其包覆于锰酸锂正极材料表面，从而将锰酸锂与电解液隔绝，起到抑制锰溶解的目的。X射线衍射表明，氟化锂与锰酸锂的共烧结过程中未发生氟掺杂，因此未引起锰酸锂的结构变化。通过对不同氟化锂包覆量电化学阻抗谱的研究，能够确定最合适的氟化锂包覆量。相比原始锰酸锂样品，经氟化锂包覆的锰酸锂正极材料与金属锂和石墨组成的软包电池均表现出了更加优异的电化学性能。其中，软包全电池能量密度达到183 Wh/Kg,1C条件下常温与高温循环1 000圈后容量保持率可达90.3%与75.7%。

Thermodynamics of metallurgical processes in manganese-based melts

The theory of quasi-regular solutions may be used to convert the molar interaction parameters from one type of alloy to another. Hence, the thermodynamic characteristics of manganese alloys may be estimated from data for iron alloys. On that basis, the molar and mass interaction parameters of elements in manganese melts may be calculated, as well as the heats of solution and activity coefficients of the elements and the change in Gibbs energy on reduction, desulfurization, denitrogenation, and reductive dephosphorization of manganese and also in the refining of manganese by chlorides and fluorides. The possibility of removing impurities from manganese is assessed.

Some data on the infiltration of porous iron-manganese alloys with copper and its alloys

Summary It is clearly shown that nonporous iron-manganese-copper alloys can be produced by infiltrating an iron-manganese matrix with copper or copper alloys.Additional data have been obtained on the effectiveness of copper, a copper-manganese master alloy, and brass as infiltrating materials; the feasibility of producing a nonporous iron-manganese alloy free from oxide inclusions is demonstrated.Data are presented on the formation of iron-manganese-copper alloys with different manganese contents during infiltration with copper and copper-manganese master alloys, under different infiltration conditions.The extent of phase interaction during infiltration and the condition of boundaries in alloys produced under different infiltration conditions have been investigated.

On the application of mechanical alloying to obtain the alloys of the Cu-Mn-Ni system used as solders

Methods for obtaining alloys of the Cu-Mn-Ni system with the preliminary mechanical alloying of the components and by direct alloying are compared. It is established that the first technology provides substantially lower waste of manganese (about by a factor of two) than the second one, which is highly important to produce solders with strongly controllable additives. It is shown that, as the treatment time of mechanically alloying materials increases, their temperature properties correspond to alloys obtained by direct alloying the components. The proposed method seems to be promising for production of relatively small amounts of alloys of components which differ in density, melting point, volatility, interaction with gases, and other physical-mechanical properties.

High temperature properties of ductile CuAlNi shape memory alloys with boron additions

The use of polycrystalline CuAlNi alloys for high temperature applications is restricted to very small shape changes due to their brittle nature. Additions of alloying elements such as manganese and boron have been introduced to improve the ductility of the material. The behaviour of these alloys has been studied in terms of the influence of these elements on the stability of the microstructure after high temperature annealing or after room and high temperature deformation. The results show that the martensitic structure produced by quenching the alloy from the β-temperature has a lower degree of order than that obtained after further annealing at 300°C for up to an hour. Also, the alloys containing higher boron concentrations present a lower degree of order in all cases. Similarly, the ductility has been much influenced by the boron content. The ductility is greater, in particular at high temperatures, in the alloys with lower concentration of boron.     

Factors Affecting Silicomanganese Production using Manganese Rich Slag in the Charge

Silicomanganese is widely used as a complex reducer and an alloying addition in the production of various grades of steel due to its economic and metallurgical advantages. It is also used as a semi‐product in the manufacture of medium‐ and low‐carbon ferromanganese and metallic manganese. Manganese‐rich slag, resulting from high carbon ferromanganese production, has the advantages of high manganese content, high Mn/Fe ratio, low excess oxygen, low phosphorus content, low fine content and low cost. Such slag seems to be very attractive to use as raw materials for the production of silicomanganese alloys. In the present study, experimental heats were designed and carried out to optimise the factors affecting the production process of silicomanganese using manganese rich slag in the charge. The results of pilot plant experimental heats showed that the optimum metallic yield and recoveries of manganese and silicon are obtained with an initial slag basicity, (CaO + MgO) / (Al₂O₃), of 1.8 by using dolomite as fluxing material and charging quartzite and fluorspar in percentage of 25% and 4% of the blend, respectively. The results also showed that an amount of 30% of coke in excess of the stoichiometric amount should be added. These results are relative for the specific high Al₂O₃ ores used.
