Electrodeposition Technologies for Li‐Based Batteries: New Frontiers of Energy Storage

Abstract

Electrodeposition induces material syntheses on conductive surfaces, distinguishing it from the widely used solid‐state technologies in Li‐based batteries. Electrodeposition drives uphill reactions by applying electric energy instead of heating. These features may enable electrodeposition to meet some needs for battery fabrication that conventional technologies can rarely achieve. The latest progress of electrodeposition technologies in Li‐based batteries is summarized. Each component of Li‐based batteries can be electrodeposited or synthesized with multiple methods. The advantages of electrodeposition are the main focus, and they are discussed in comparison with traditional technologies with the expectation to inspire innovations to build better Li‐based batteries. Electrodeposition coats conformal films on surfaces and can control the film thickness, providing an effective approach to enhancing battery performance. Engineering interfaces by electrodeposition can stabilize the solid electrolyte interphase (SEI) and strengthen the adhesion of active materials to substrates, thereby prolonging the battery longevity. Lastly, a perspective of future studies on electrodepositing batteries is provided. The significant merits of electrodeposition should greatly advance the development of Li‐based batteries.

Electrodeposition of (hydro)oxides for an oxygen evolution electrode

“…For the deposition of active metal-based materials, the procedure can be achieved in ionic liquids, organic solution or even molten salts. 27,28,40,102 In particular, directly fabricating nanostructured (hydro)oxides with a selective morphology and high surface area on to a conductive substrate using electrodeposition routes has become the focus of recent research. These unique nanostructured (hydro)oxides are expected to be promising functional electrodes materials for OER catalytic applications.…”

“…[24][25][26][27] Although some excellent review articles on electrodeposition have been published, they mainly focus on alloys, batteries, or photoelectrodes. 18,21,28 The latest progress on metal (hydro)oxide OER electrocatalysts prepared via electrodeposition has rarely been reviewed. In this minireview, we focus on electrodeposition strategies for metal (hydro)oxide design and OER applications.…”

Sulfide and Oxide Inorganic Solid Electrolytes for All-Solid-State Li Batteries: A Review

“…Furthermore, the fundamentals of ASSBs were reviewed by several authors [ 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 ]. The number of reviews on various aspects of electrolytes, cathodes, mechanical properties, and interface engineering has grown exponentially since 2018 [ 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 ...…”

Flexible and Wearable Power Sources for Next‐Generation Wearable Electronics

“…Strong interparticle or particleÀ substrate connections are demanded to avoid the detachment of active materials under deformation. [131] In this case, electrodeposition is an effective approach to directly in-situ grow the active material on the conductive current collectors, avoiding the use of binders and other electrochemically inert materials. In addition, ultrathin active materials for air electrodes play significant role in enhancing the energy density of metalÀ air batteries in a limited weight and volume.…”
