Phase Equilibria of the Aqueous Systems Containing Lithium and Carbonate Ions

1 Introduction Alkaline lakes are widely distributed in the area of the Qinghai-Tibet Plateau.Most of the salt lakes are famous for their high concentration of lithium,potassium,magnesium,boron(Ma,2000).In recent years,as a new energy material,lithium and its compounds are widely used in the new area,such as aerospace industry,nuclear

Solid–liquid Phase Equilibria in the Aqueous Ternary System Containing Lithium,Potassium,and Sulfate ions at 288.15 K

1 Introduction Salt lakes are widely distributed in the western of China,especially in the area of Qinghai-Xizang(Tibet)Plateau.A series of salt lakes in the Qaidam Basin,located in Qinghai Province,China,is famous for their abundance of lithium,potassium and boron resources(Zheng et al,1988;Deng et al,2012).It is well known that the

Factors affecting specific capacity and rate performance of aqueous Li4Ti5O12 battery

The use of an aqueous slurry in the manufacture of lithium ion batteries has the advantages of being environmentally friendly,harmless to the human body,and low in production cost.In this study,the factors affecting the specific capacity and rate performance of the aqueous Li4Ti5O12 battery were studied,including the Li4Ti5O12 structure,aqueous binder,conductive agent,and surface density.The results show that a spherical secondary particle structure of Li4Ti5O12 is beneficial to its discharge rate performance.In addition,an aqueous binder with high conductivity improves the specific capacity and high rate charge/discharge performance of the battery,and when the amount of binder is 3%,the Li4Ti5O12 battery performs better.A chain structure in the conductive agent also improves the specific capacity and discharge rate performance of the Li4Ti5O12 battery,and increases the degree to which the discharge rate performance of the conductive agent can be further improved.Lastly,the lower the surface density,the better the rate performance of the Li4Ti5O12 battery.
