Nanocomposite Electrolytes

ABSTRACTNanocomposite electrolytes based on lithium hectorite (LiHect) clay dispersed in highdielectric organic solvents such as ethylene carbonate (EC) and propylene carbonate (PC) are shown to exhibit room-temperature conductivities exceeding 10−4 S/cm. The LiHect-based composites reveal lithium ion transference numbers of ∼0.8, as measured by the steady-state current method. In addition, dynamic rheological techniques show this system to be mechanically stable with elastic modulus G' exceeding 107 dynes/cm 2 and yield stress exceeding 104 dynes/cm2.

Efficient Recovery

The consumption of lithium has increased dramatically in recent years. This can be primarily attributed to its use in lithium-ion batteries for the operation of hybrid and electric vehicles. Due to its specific properties, lithium will also continue to be an indispensable key component for rechargeable batteries in the next decades. An average lithium-ion battery contains 5–7% of lithium. These values indicate that used rechargeable batteries are a high-quality raw material for lithium recovery. Currently, the feasibility and reasonability of the hydrometallurgical recycling of lithium from spent lithium-ion batteries is still a field of research. This work is intended to compare the classic method of the precipitation of lithium from synthetic and real pregnant leaching liquors gained from spent lithium-ion batteries with sodium carbonate (state of the art) with alternative precipitation agents such as sodium phosphate and potassium phosphate. Furthermore, the correlation of the obtained product to the used type of phosphate is comprised. In addition, the influence of the process temperature (room temperature to boiling point), as well as the stoichiometric factor of the precipitant, is investigated in order to finally enable a statement about an efficient process, its parameter and the main dependencies.

Lifepo4 Cathode

Olivine compounds LiFePO4 were prepared by the solid state reaction, and the electrochemical properties were studied with the composite cathode of LiFePO4/mesocarbon nanobead. High discharge rate performance can be achieved with the designed composite cathode of LiFePO4/mesocarbon nanobead. According to the experiment results, batteries with the composite cathode deliver discharge capacity of 1087mAh for 18650 type cell at 20C discharge rate at room temperature. The analysis shows that the uniformity of mesocarbon nanobead around LiFePO4 can supply enough change for electron transporting, which can enhance the rate capability for LiFePO4 cathode lithium ion batteries. It is confirmed that lithium ion batteries with LiFePO4 as cathode are suitable to electric vehicle application.
