“…Porous structure of electrodes has significant influence on both ion and electron transport, thus an express passage could reduce the ESR and joule heat effectively. Delicate pore structures in the electrode can be obtained both in the process of coating and calendaring (Bae et al, 2013;Wang et al, 2014;Liu et al, 2018d;Cheng et al, 2019), or by physical/chemical etch after the electrode was prepared (Pröll et al, 2014;Mangang et al, 2016;Park et al, 2019). Multi-scale pore structures (Liu et al, 2017b(Liu et al, , 2018dCheng et al, 2019) in the electrode is expected to enlarge the passageway of Li-ion diffusion and reducing the internal resistance.…”

“…Kim et al (2018) designed a highly ordered and hierarchical (HOH) graphite anode through the laser ablation, the HOH electrode has a porosity up to 50% which promotes ionic transport throughout the cell and mitigated the concentration polarization. Recently, Park et al (2019) made laser structuring thick electrode with a porosity of 26% which lead to the enhancement of the power and energy densities simultaneously. The femtosecond laser creates uniformly spaced micro-grooves on the electrode, which greatly improves the Li + kinetics and decreases the joule heat especially at high current density.…”

As the most widely used energy storage device in consumer electronic and electric vehicle fields, lithium ion battery (LIB) is closely related to our daily lives, on which its safety is of paramount importance. LIB is a typical multidisciplinary product. A tiny single cell is composed of both organic and inorganic materials in multi scale. In addition, its relatively closure property made it difficult to be studied on line, let alone in the battery pack or system level. Safety, often manifested by stability on abuse, including mechanical, electrical, and thermal abuses, is a quite complicated issue of LIB. Safety has to be guaranteed in large scale application. Here, safety issues related to key materials and cell design techniques will be reviewed. Key materials, including cathode, anode, electrolyte, and separator, are the fundamental of the battery. Cell design and fabrication techniques also have significant influence on the cell's electrochemical and safety performances. Here, we will summarize the thermal runaway process in single cell level, and some recent advances on battery materials and cell design.

“…In addition, similar cycling capacity retention for the unstructured and laser-structured microstructure have been achieved for the first 10 cycles. Similarly, Park et al [10] have laser-structured an NMC cathode with uniformly spaced micro-grooves with no evidence of melting at the edge of laser-structured features as well. Because laser processing induces a loss of active material, areal specific capacity measured at 0.1C is higher for the non-structured electrode.…”

“…Several authors [7][8][9][10][11][12][13][14][15][16][17][18][19][20][22][23][24][25] have proposed different electrode architectures to reduce the tortuosity factor and improve electrochemical cell performance through experiments and modeling. These methods are listed in Table 1 and are detailed below.…”

The present work utilizes Direct Laser Interference Patterning (DLIP) in conjunction with a polygon scanner system to fabricate micro and nanostructures on the surface of nickel foils. A picosecond pulsed laser source with an average power of ∽470 W is used to pattern line‐like structures having spatial periods of 11.0 and 25.0 µm and a maximum structure depth of up to 15 µm. The scanning speed and the number of consecutive scans, ranging from 5 to 500, are varied in order to assess their influence on the structure formation process. Furthermore, the use of ultra‐short pulses permitted the production of hierarchical surface structures having up to four feature size levels, because of incubation effects and growth of different types of Laser Induced Periodic Surface Structures (LIPSS). 2D‐Fast Fourier Transforms are applied to Scanning Electron Microscopy images for analyzing the evolution of features from the nano‐ to microscale. The method proposed here permitted the reduction of 22% in the overpotential of the Hydrogen Evolution Reaction (HER), which linearly correlates to the drop in energy required to drive this chemical reaction.This article is protected by copyright.
