“…Advanced X-ray technologies reveal the micropores of N-LIG are more disordered after cycling, suggesting the microporous level are enhanced upon cycling. Compared with the previous report [29] on the PI-derived LIG, these small organic molecules-derived LIG exhibited an unusual structural evolution process, leading to a 7-fold and 5-fold increase in capacities after 2000 cycles for N-LIG and P-LIG, respectively.…”

Laser scribing technology is a straightforward technique to fabricate porous graphene, yet only conducted with polymeric precursors. Compared to polymers, molecular engineering of small organic molecules is much easier, which can be used to modify the graphene with tailored performance. Here we report the first employment of a laser to respectively transform small organic molecules, pentacene quinone and tetraazapentacene quinone (TAPQ), into graphene (P‐LIG and N‐LIG) as high‐performance lithium‐ion battery anodes. The TAPQ, as the N‐fused molecular precursor, produces nitrogen‐doped graphene. Both N‐LIG and P‐LIG exhibit significant self‐enhancement of capacity upon cycling; the N‐LIG anode delivers reversible capacities of 5863 mAh g‐1 at 0.2 A g‐1 and retains 1970 mAh g‐1 at 2 A g‐1 after another 500 cycles, which is the best performance for the graphene‐type anode. Kinetics studies and structural characterizations verify that the surface‐ and diffusion‐controlled processes are both progressively optimized, providing extra lithium storage upon cycling. It is also supported by small‐angle X‐ray scattering that the disordering level of micropores is increased upon cycling for N‐LIG, corresponding to the enhancement of microporous level. Our work successfully develops a novel facile approach to fabricating heteroatom‐doped microporous graphene exhibiting high performance and provides new insight into the lithium storage mechanism.

“…Second, although graphite has a layered structure with closed pores, LIG possesses an open-pore structure that facilitates easy ion transport during charging/discharging and enables high-power characteristics. Recently, Shim et al [151] reported the facile fabrication of LIG on a Cu foil by dry transfer of LIG produced on a PI film. The inherent 3D hierarchical porous structure of the LIG was preserved after being transferred to Cu foil to form a LIG-based LIB anode.…”

Laser‐induced graphene (LIG) is a newly emerging 3D porous material produced when irradiating a laser beam on certain carbon materials. LIG exhibits high porosity, excellent electrical conductivity, and good mechanical flexibility. Predesigned LIG patterns can be directly fabricated on diverse carbon materials with controllable microstructure, surface property, electrical conductivity, chemical composition, and heteroatom doping. This selective, low‐cost, chemical‐free, and maskless patterning technology minimizes the usage of raw materials, diminishes the environmental impact, and enables a wide range of applications ranging from academia to industry. In this review, the recent developments in 3D porous LIG are comprehensively summarized. The mechanism of LIG formation is first introduced with a focus on laser‐material interactions and material transformations during laser irradiation. The effects of laser types, fabrication parameters, and lasing environment on LIG structures and properties are thoroughly discussed. The potentials of LIG for advanced applications including biosensors, physical sensors, supercapacitors, batteries, triboelectric nanogenerators, and so on are also highlighted. Finally, current challenges and future prospects of LIG research are discussed.

“…While air cathodes have dominated the LIG battery literature, there are a few recent reports of the method's extension into other battery chemistries (Table S15, Figure 23(a)). LIG and LIG-based composites have been recently used as an anode material for lithiumion batteries [228][229][230]. An LIG/MnO/Mn 3 O 4 composite demonstrated an impressive capacity of 836 mAh g −1 at 0.2 A g −1 [230], but areal capacities for all Li-ion reports remain far below the 4 mAh cm −2 typically achieved via slurry casting (typically < 1 mAh cm −2 ) due to the low loadings of active material typically achieved (1-3 mg cm −2 )(Figure 23(b,c)).…”

Advancements in electrochemical energy storage devices such as batteries and supercapacitors are vital for a sustainable energy future. Significant progress has been made in developing novel materials for these devices, but less attention has focused on developments in electrode and device manufacturing. While electrodes are traditionally made through slurry casting of electrochemically active material, advanced manufacturing techniques enable patterning of novel electrode architectures and control of device geometries in real-time, which can potentially result in electrodes with increased loading, improved electrochemical performance, and added functionality, such as flexibility and wearability. These inexpensive methods are particularly suited for lab-scale research and start-up companies, as they enable rapid prototyping without a full device production line. The present review describes three main methods of advanced manufacturing (inkjet printing, direct ink writing, and laser-induced graphene techniques) and evaluates the performance of batteries and supercapacitors fabricated via these methods in comparison to traditionally manufactured devices.
