Progressive chemical .delithiation of commercially available lithium cobalt oxide (LiCoO2) showed consecutive changes in the crystal properties. Rietveld refinement of high resolution X-ray and neutron diffraction revealed an increased lattice parameter c and a reduced lattice parameter a for chemically delithiated samples. Using electron microscopy we have also followed the changes in the texture of the samples towards what we have found is a critical layer stoichiometry of about LixCoO2 with x=1/3 that causes the grains to exfoliate. The pattern of etches by delithiation suggests that unrelieved strain fields may produce chemical activity.

“…In a Li-ion battery

can be delithiated (charged) to up to x =0.5 which corresponds to 140 mAh/g (theoretically 274 mAh/g) [3] . This value can be improved to 200 mAh/g ( x =0.7) by substituting the Co in the outer layer of the core with Ti, Al or Mg (Chapter 1 of [4,14] ).…”

“…On the one hand, novel material chemistries are being investigated, for example, moving from the classical graphite anode to high capacity composites of graphite including silicon, and moving from the original cathode LiCoO 2 to cheaper and safer high‐power cathodes such as spinel LiMn 2 O 4 (LMO), and higher energy compounds such as LiMn 1.5 Ni 0.5 O 4 (LMNO) . On the other hand, the classical lithium ion battery can still be improved to some extent, by nanoscaling the electrodes, moving to complex 3D battery architectures, carbon nanotube or carbon nanosheet based electrodes, and interface engineering …”

Interface modification is a heavily investigated method of extending the lifetime of lithium ion batteries. While many studies have explored the effect of interface coating on the lifetime, the rate capability is often overlooked. In this study, the authors investigated the influence of ultrathin (<10 nm) atomic layer deposition (ALD) coatings of amorphous Al2O3 and amorphous TiO2. It is found that, on thin‐film anatase TiO2, the rate capability is unaffected by an amorphous TiO2 coating since it does not pose an additional impedance on the system, while Al2O3 coatings are detrimental for the rate performance due to the 1.5 × 1012 Ω cm resistivity toward lithium ions. A thicker than 2 nm ALD Al2O3 film is found to block lithium transfer completely, resulting in a purely capacitive film. Solvent oxidation is studied on thin‐film LiMn2O4. The authors demonstrate that both coatings can partially solve the solvent decomposition. However, the kinetic bottleneck posed by 1 nm Al2O3 is still greater than the uncoated LiMn2O4, leading to worsened rate capability. ALD TiO2 on the other hand can prevent most of the solvent decomposition, resulting in smoother electrodes. The absence of the decomposition layer and lithium conducting properties of the ALD TiO2 films results in an improved rate capability for the ALD TiO2 coated electrode.

Nickel-containing residue (NCR) is a hazardous solid waste from battery production lines. Recently, the interest in recovering valuable metals from NCR has increased because sustainable utilization of resources is more and more valued. Drying is a key part of the recovery process. In this study, we measured the dielectric properties of the NCR for different moisture contents and temperatures using the cavity perturbation method at 2.45 GHz. The microwave absorption characteristics of NCR had a positive correlation with the moisture content, while it was less efficient in the 20-180°C temperature range. Then found that the microwave drying data at different microwave powers (400-700 W) and for different sample weights (60-120 g) have a better fit with the Midilli-Kucuk model. The activation energy (Ea) was received as 9.76 W/g using an exponential expression based on the Arrhenius equation. Finally, the energy consumption reduce 110 W·h/kg than that of drying with a single microwave power by optimizing the microwave drying process.
