“…Compared to the traditional surface modification methods, such as sol-gel (Sun et al 2002a, b;Verdier et al 2007), and gas-suspension spray coating (Oh et al 2004), atomic layer deposition (ALD) technique provides elegant control over the coating thickness, thus producing ultrathin and conformal morphology (Han et al 2014;Jung et al 2010a;Scott et al 2010;Zhao and Wang 2012). It has been recently demonstrated that the ultrathin coatings of Al 2 O 3 layer (\1 nm) on LiCoO 2 electrode composite by ALD technique deliver excellent durability as well as high rate in comparison to bare LiCoO 2 electrode (Jung et al 2010b;Lee et al 2010;Scott et al 2010).…”

We report improved cycling performance of high-voltage LiNi 0.5 Mn 1.5 O 4 cathode for lithiumion batteries by modifying its surface with ultrathin layer coating of Al 2 O 3 (\1 nm) using atomic layer deposition (ALD) technique. Four and six layers of ALD Al 2 O 3 were coated directly on the porous LiNi 0.5 Mn 1.5 O 4 nanoparticle (*200 nm) slurry composite. Electrochemical characterization results show that LiNi 0.5 Mn 1.5 O 4 electrode with four and six layers of ALD Al 2 O 3 maintained 92 and 98 % of their initial capacity after 200 cycles, respectively, in comparison to bare LiNi 0.5 Mn 1.5 O 4 electrode which showed 84 % capacity retention. We show that the ALD Al 2 O 3 coated cathode surface is protected from undesired side reactions occurring at the electrode/electrolyte interface. For the first time, we used XPS studies to investigate the surface chemistry of ultrathin ALD Al 2 O 3 coated LiNi 0.5 Mn 1.5 O 4 and confirmed that the ultrathin ALD Al 2 O 3 layer reduces side reactions involving organic components of the electrolyte decomposition product in high-voltage cathodes.

“…The latter showed improved cyclability, while the performance of the former was decreased . Many materials have been investigated since research on ALD coatings for lithium‐ion batteries started in 2010, most of the work dealing with ALD Al 2 O 3 coating of various thicknesses on electrode powders, composite electrode, or even the separator . These coatings can suppress SEI formation, act as an artificial SEI, strengthen the electronic network by knitting the electrode together, act as an hydrofluoric acide (HF) scavenger, help maintain particle morphology, prevent unwanted phase transformations, and block metal dissolution.…”

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.

“…Recently, there has been a lot of interest in coating cathode and anode particles by ALD with a protective layer of Al 2 O 3 . Improved stability by depositing Al 2 O 3 on LiCoO 2 particles has been demonstrated, [54][55][56] as well as for depositing Al 2 O 3 on the cathode material LiNi 1=3 Mn 1=3 Co 1=3 O 2 . 57 Depositing Al 2 O 3 on natural graphite particles was also shown to improve the cycle-life.…”

Nanostructuring is targeted as a solution to achieve the improvements required for implementing Li-ion batteries in a wide range of applications. These applications range in size from electrical vehicles down to microsystems. Atomic layer deposition (ALD) could be an enabling technology for nanostructured Li-ion batteries as it is capable of depositing ultrathin films (1-100 nm) in complex structures with precise growth control. The potential of ALD is reviewed for three battery concepts that can be distinguished, i.e., particle-based electrodes, 3D-structured electrodes, and 3D all-solid-state microbatteries. It is discussed that a large range of materials can be deposited by ALD and recent demonstrations of battery improvements by ALD are used to exemplify its large potential.
