6 FAQs about [Sierra Leone LiCoO2 Battery Processing]

What is a licoo 2 (LCO) battery?

LiCoO 2 (LCO) batteries with high energy density and excellent electrochemical properties have been widely used in consumer electronics . Recycling of expensive LCO is critical to the sustainability of cobalt as well as lithium resources.

How is licoo 2 recycled?

Why is regenerated licoo 2 not suitable for high-voltage batteries?

Meanwhile, the solid electrolyte interphase (SEI) has also been found unstable at high-voltage [24, 25]. As a result, the constant electrode/electrolyte side reaction occurs, resulting in the increased cell resistance. Hence, the regenerated LiCoO 2 by this method may not meet rigorous standards required by the battery industry.

What is the leaching behavior of licoo 2 in 1 m HNO 3?

The leaching behavior of LiCoO 2 in 1 M HNO 3 solution at a fixed S:L ratio of 20 g l −1 and 75 °C is shown in Fig. 5. In the absence of a reducing agent, the leaching efficiencies of cobalt and lithium leveled off within 30 min with a low extraction of Co (40%) and Li (75%).

How was licoo 2 fabricated?

The electrodes were fabricated by mixing LiCoO 2 powder, carbon black (SUPER C65, Imerys S.A.), and polyvinylidene fluoride (PVDF, Solef 5130, Solvay S.A.) in a mass ratio of 8:1:1. PVDF was dissolved in N-methyl-2-pyrrolidone (TCI [Shanghai] Development Co., Ltd.) in advance at a concentration of 5 wt%.

How is licoo 2 obtained?

Next, the cathodic active material, LiCoO 2, was obtained by burning off carbon and binder in the temperature range 500–900 °C for 0.5–2 h. Third, LiCoO 2 in a nitric acid solution was leached in a reactor ( Fig. 3 ), which was placed in a constant-temperature water bath.
