Dueto future plans to explore Mars and the outer planets, NASA has interest in developing lithium-ion rechargeable batteries that are capable of operating at low temperatures. To address these problems, w have initiated research focused upon t h e development of advanced electrolyte systems for lithium-ion cells with improved low temperature performance. Promising electrolyte solutions were sel...

In this study, a process for preparing battery-grade lithium carbonate with lithium-rich solution obtained from the low leaching of fly ash by adsorption method was proposed. A carbonization-decomposition carried out to remove impurities such as iron and aluminum. First, primary Li2CO3 treated CO2 get more soluble bicarbonates. The decomposition LiHCO3 produced insoluble at 90 °C And smashed ai...

Olivine LiFePO4 has received much attention recently as a promising storage compound for cathodes in lithium ion batteries. It has an energy density similar to that of LiCoO 2, the current industry standard for cathode materials in lithium ion batteries, but with a lower raw materials cost and an increased level of safety. An inherent limitation of LiFePO4 acknowledged by researchers studying t...
