“…Such films exhibit a stable discharge capacity at a low C-rate (0.1C), but for a current density of 1C, the electrode reached 40% of the initial capacity [113]. Recently, Abe et al elucidated the deterioration mechanism of pristine ZrO 2 -coated NMC333 thin films prepared by PLD on a (110)STO substrate maintained at two temperatures of 25 and 700 • C; the oxygen pressure ranged from 3.3 to 10 Pa [114]. Characterization was performed by cyclic voltammetry, in situ X-ray diffraction, and in situ neutron reflectometry.…”

This review article presents a survey of the literature on pulsed laser deposited thin film materials used in devices for energy storage and conversion, i.e., lithium microbatteries, supercapacitors, and electrochromic displays. Three classes of materials are considered: Positive electrode materials (cathodes), solid electrolytes, and negative electrode materials (anodes). The growth conditions and electrochemical properties are presented for each material and state-of-the-art of lithium microbatteries are also reported.

“…For example, amorphous Li 1.2 Co 0.8 S 0.2 O 2.4 was PLD grown from a pellet with LiCoO 2 mixed with Li 2 S . In some cases the rock salt phase is targeted and PLD coatings such as ZrO 2 are used . Note, some studies target the LiNi x Mn y Co z O 2 compositions, where x + y + z =1, taking advantage of the Ni 2+ to Ni 4+ redox couple during cycling.…”

Emerging applications for robust small format or distributed devices feature a need for power and rechargeable lithium-ion batteries could play a significant role. This review focuses on a high precision technique to controllably grow thin-film electrodes or full all-solid-state batteries, that is, pulsed laser deposition (PLD). The technique and solidstate batteries are introduced followed by a detailed showcase of the depth of PLD-based growth undertaken on cathodes, electrolytes, anodes and whole microbatteries. Emphasis is placed on the various characterization techniques available to study PLD grown components and devices, and how interfaces become both critical and arguably easier to probe in PLD grown films or devices. This work provides a perspective on the techniques, its opportunities for electrodes and devices, and how to probe the resulting growth and its evolution in batteries.

“…Many thin-film studies have investigated the effect of an additional amorphous or polycrystalline coating; however, only a few studies have explored the impact of an epitaxially matched layer (ZrO 2 , BaTiO 3 ) on the surface of a highly crystalline LiCoO 2 thin film. 24 , 48 Therefore, a large knowledge gap currently exists in how the alignment of the crystal structures across such epitaxial coating–cathode interface can enhance lithium transport while preventing parasitic reactions with the adjacent electrolyte.…”

“…5,19,27−29 However, the exact nature and contribution of these surface coatings are not fully understood and still under debate. 24 Another strategy to enhance the cycle life and safety of lithium-ion batteries is to combine successful LiCoO 2 -type cathode materials with a solid electrolyte. Although solid electrolytes are inherently safer as compared to liquid electrolytes, their limited stability against such high-voltage cathode materials remains a major bottleneck.…”

Layered lithium transition-metal oxides, such as LiCoO 2 and its doped and lithium-rich analogues, have become the most attractive cathode material for current lithium-ion batteries due to their excellent power and energy densities. However, parasitic reactions at the cathode–electrolyte interface, such as metal-ion dissolution and electrolyte degradation, instigate major safety and performance issues. Although metal oxide coatings can enhance the chemical and structural stability, their insulating nature and lattice mismatch with the adjacent cathode material can act as a physical barrier for ion transport, which increases the charge-transfer resistance across the interface and impedes cell performance at high rates. Here, epitaxial engineering is applied to stabilize a cubic (100)-oriented TiO layer on top of single (104)-oriented LiCoO 2 thin films to study the effect of a conductive coating on the electrochemical performance. Lattice matching between the (104) LiCoO 2 surface facets and the (100) TiO plane enables the formation of the titanium mono-oxide phase, which dramatically enhances the cycling stability as well as the rate capability of LiCoO 2 . This cubic TiO coating enhances the preservation of the phase and structural stability across the (104) LiCoO 2 surface. The results suggest a more stable Co 3+ oxidation state, which not only limits the cobalt-ion dissolution into the electrolyte but also suppresses the catalytic degradation of the liquid electrolyte. Furthermore, the high c-rate performance combined with high Columbic efficiency indicates that interstitial sites in the cubic TiO lattice offer facile pathways for fast lithium-ion transport.
