Towards high-performance microscale batteries: Configurations and optimization of electrode materials by in-situ analytical platforms

In situpolymerization process: an essential design tool for lithium polymer batteries

“…A detailed description of the type of mLBs and the different electrode configurations are available elsewhere. 281,574,576,577 In the case of interdigitated cell architecture, the specific capacity, energy/power density, etc., can be improved by increasing the height of the deposited electrodes, which facilitates an increased mass-loading of the active materials. 578 Like conventional LBs, the electrode|electrolyte interface/interphase significantly influences the performance metrics of mLBs.…”

Polymer Binders: Characterization and Development toward Aqueous Electrode Fabrication for Sustainability

“…Thus, SEM-EDS can be used to visualize the electrode microstructure. Post-mortem imaging of cycled electrodes can also reveal if cracks formed due to lithiation-induced volume changes, which would lead to a loss of electrical contact and is a direct failure of the binding material [ 17 ].…”

How to Pack a Punch – Why 3D Batteries are Essential

“…Here also, we disagree with the classification proposed by the authors. [30] Fiber/cable-shaped μRBs (Figure 7(a-c)) cannot be attributed to one-dimensional batteries, since high conductivity is equally important along and across the wire. Moreover, if the electrode incorporates a current collector, the charge/ discharge ion transfer occurs across the cable-shaped battery.…”

“…A prototype of a 1D μRB was proposed in 2012 by Kwon et al . [31] Later designs of 3D interdigitated and stacked μRBs are shown in Figure 7(f-i), [30] respectively. Whatever the design, the cathode and anode in μRBs, planar, and 3D thinfilm microbatteries must maintain sufficient electrical conductivity in order to work properly.…”

“…Additional 3D-configuration variants: h) periodically-coated segments and i) the 3D scaffold is coated with anode and electrolyte, and cathode materials fill the remaining volume, j) swiss-roll-like configuration. Taken with permission from Elsevier (2020) Reference [30].…”
