“…This has been demonstrated for many cathode active materials, including LiMn 2 O 4 [35,36], LiFePO 4 [37] and Li(NiMnCo)O 2 (NMC) [34,38,39]. For instance, Pröll et al used a fiber laser at λ = 515 nm with a pulse energy and width of 0.125 μJ and 350 fs, respectively, to create 3D grid architectures with an aspect ratio of ~1.7 in 60 μm thick LiMn 2 O 4 cathode active material [35].…”

Harnessing pulsed laser ablation processes in the manufacturing of energy storage devices is a new and promising strategy for the facile development of next-generation Li-ion batteries. In laser ablation, a pulsed laser is focused on a material surface such that the transfer of energy causes the removal of localized material via high throughput and environmentally-friendly processing. This chapter will provide a summary of the recent advances in laser ablation technologies for producing Li-ion battery materials and components. In terms of electrode optimization, it will examine the use of pulsed lasers to: (1) generate large specific surface area nanoparticles of active materials or stable integrative anodes; (2) deposit compositionally complex and stoichiometric thin film active materials; (3) create electrode architectures with increased Li-ion diffusion kinetics, enhanced wettability or free space to accommodate Si anode volume expansions, and; (4) remove the superficial inactive or solid electrolyte interface layers from electrode surfaces. It will also investigate the laser ablation of current collectors to produce textures with improved adhesion and the use of pulsed lasers for cutting and structuring solid ceramic electrolyte. Finally, this chapter will discuss the application of laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) for chemical composition analysis of Li-ion batteries throughout their operating cycle.

“…Toward this goal, innovating battery structures by reconfiguring battery components is an effective strategy. To date, there have been several novel battery configurations reported in references (shown in figure 1) including '3D grid electrodes + stacking' [19][20][21][22][23][24], '3D grooved electrodes + stacking' [25][26][27], '3D grooved electrodes + interdigitating' [28][29][30][31][32], '3D rod array electrodes + interdigitating' [33,34], and '3D concentric rod/pore array + interdigitating' [35]. In these new battery configurations, the pathways of Li-ions transport between cathodes and anodes are reshaped by innovating electrode structures, thus Li-ion transport distance can be reduced.…”

Thick electrodes with higher energy density are highly desirable for lithium-ion batteries (LIBs). However, the sluggish transport of Li-ions in thick electrodes is a critical challenge. In this study, a novel synchronously interdigitated/winded battery configuration enabled by 3D printing is proposed. The cathode, separator, and anode are synchronously interdigitated in the core and synchronously winded in the outer-rings to form an integrated full battery. With this novel battery configuration, Li-ions can transport between neighboring cathode and anode, thereby significantly reduce the transport distance of Li-ions, and improve the electrochemical reaction kinetics. To evaluated the electrochemical performance of this battery configuration, this investigated the effects of various parameters including the electronic conductivity, electrode porosity, electrode line width, separator thickness, and number of winded outer-rings on the electrochemical performance through numerical simulations. Results showed that electronic conductivity is the most crucial factor in determining the electrochemical performance. In combination with multi-material 3D printing, the battery configuration proposed in this study may be utilized to build LIBs with higher energy density.
