Abstract:

The recent renaissance of lithium metal batteries as promising energy storage devices calls for in operando monitoring and control of electrochemical evolution of lithium metal morphologies. While the development of plasmonics has led to significant advancement in real-time and ultrasensitive chemical and biological sensing and surface-enhanced spectroscopies, alkali metals featured by ideal free electron gas models have long been regarded as promising plasmonic materials but seldom been explored due to their high chemical reactivity. Here, we demonstrate the in operando plasmonic monitoring of the electrochemical evolution of lithium metal during battery cycling by taking advantage of selective electrochemical deposition. The relationships between the evolving morphologies of lithium metal and in operando optical spectra are established both numerically and experimentally: Ordered growth of lithium particles shows clear size-dependent reflective dips due to hybrid surface plasmon resonances, while the formation of undesirable disordered lithium dendrites exhibits a flat spectroscopic profile with pure suppression in reflection intensity. Under the in operando plasmonic monitoring enabled by the microscopic morphology of metal, the differences of lithium evolutionary behaviors with different electrolytes can be conveniently identified without destruction. At the intersection of energy storage and plasmonics, it is expected that the ability to actively control and in operando plasmonically monitor electrochemical evolution of lithium metal can provide a promising platform for investigating lithium metal behavior during electrochemical cycling under various working conditions.

Abstract:

Research in lithium-ion batteries is often focused on optimising the electrode performance of either the anode1 or cathode2. One common research strategy is to explore alternative electrode material candidates for use as both the anode3 and cathode4. Another approach involves optimising the performance of existing electrode materials through structured electrode architectures with nano-sized features. Incorporating nanostructure into electrode design has reported advantages of shorter ion diffusion lengths and improved rate capability during cycling5. A common and simple technique for introducing nanostructure to electrodes is the use of a photonic crystal template, particularly inverse opal photonic crystals. The porous geometry, highly interconnected material and nano-sized features of the pore walls are all believed to contribute to improved electrochemical performance in inverse opal electrodes6 7. Photonic crystal materials are more than just a structural template and are renowned for their ability to tune the wavelengths of light propagating in the structure8 9. The repeating dielectric material comprising the structure reflects specific wavelengths, known as the photonic bandgap or stopband, depending on the size of the repeating lattice and the refractive index contrast between the composite materials. Tuning the photonic stopband of various inverse opal materials has been extensively studied10 11. Inverse opal battery electrodes have yet to exploit the optical potential of the photonic stopband. Here, we showcase a fundamentally new operando analysis technique for lithium-ion battery electrodes adopting a photonic crystal structure. Visible spectroscopy is used to monitor the presence and position of the photonic stopband of the electrode material during battery cycling, see Figure 1. Capitalizing on the sensitivity of the photonic stopband to lattice size and refractive index contrast, shifts or changes in the optical spectrum can be correlated to the electrode environment and material performance. Several optical effects are observed throughout the cycling process and linked back to the battery performance of the anode. A TiO2 inverse opal anode is reported on here, yet the technique is versatile and should be applicable to a wide range of electrode materials possessing a photonic crystal structure.

Abstract:

Research in the field of modern battery materials demands characterization techniques which allow an inspection of atomistic processes during battery charging and discharging. Two powerful tools for this purpose are magnetometry and positron-electron annihilation. The magnetic moment serves as highly sensitive fingerprint for the oxidation state of the transition metal ions, thus enabling to identify the electrochemical ”active” ions. The positron lifetime on the other hand, is sensitive to open volume defects of the size of a few missing atoms down to single vacancies providing an unique insight into lattice defects induced by charging and discharging. An overview will be given on operando magnetometry studies of the important class of LiNiCoMn-oxide cathode materials (so-called NMC with Ni:Co:Mn ratios of 1:1:1 and 3:1:1) as well as of sodium vanadium phosphate cathodes. First operando positron annihilation studies on a battery cathode material (NMC 1:1:1) demonstrate the capability of this technique for battery research.

Abstract:

In addition to recent worldwide renewable energy commitments, advances in electrical vehicle technologies, flexible electronics, smart wearable devices, and internet of things, have contributed to the increasing demand for batteries with a wide range of electrochemical and electromechanical properties. In response, the battery industry has launched intensive research and development efforts in search for new materials, technologies, and concepts. However, these rapid developments give rise to a growing concern on the impact of this industry on Nature. Hence, the rapidly growing battery market demands resolutions for both energy and waste-management challenges in anticipation of about two million metric tons of annual battery waste generated globally. One way to resolve this energy and environment dilemma is by revising the conventional battery architecture to assure both high energy density and efficient recyclability aiming at circular economy. Within this strategy we fabricated self-standing composite electrodes that eliminated electrochemically inactive metal current collectors and binders from the Li-ion battery architecture, increasing energy density up to 40%. These electrodes were prepared via in situ mixing of as-grown single-wall carbon nanotubes (SWNTs) with aerosolized electrode active materials in ratios (≥0.25 wt%) that provide adequate electrical conductivity and mechanical robustness under stretching (≤15%), bending (d≥2 mm) and twisting (θ~180o) cycles. Remarkably, the resultant SWNT scaffold in composite electrodes operates as an intrinsic piezoresistive strain sensor (Gauge Factor ~6.2) that for the first time allows in situ/operando self-monitoring of battery structural health without interfering with electrochemical reactions. Moreover, the developed solution-free fabrication method eliminates hazardous, toxic, and environmentally harmful components and procedures from the electrode production line and allows their recycling by simple sonication and recovering of the active materials. In addition, the absence of current collector foils and binder allows for easy recycling and recovery of the constituent materials by using physical separation methods. These new features not only reduce consumption of the natural resources but also promote the eco-friendly circular economy for batteries.

Abstract:

Lithium dendrite (filaments) propagation in solid electrolytes (SEs) leading to short circuits is one of the biggest obstacles to the application of all-solid-state lithium metal batteries. Due to the lack of operando techniques that can provide high resolution, the insufficient knowledge of the lithium dendrite growth inside SEs makes it difficult to suppress the dendrite growth. To reveal the mechanism of the Li filament growth in SEs, we achieved real-time monitoring of the nanoscale Li filament growth by operando small-angle neutron scattering (SANS) in representative Li6.5La3Zr1.5Nb0.5O12 SEs. On continuous plating, the Li filament growth is not simply an accumulation of Li, but there is a dynamic evolution due to the competition between the Li filament growth and self-healing. With the aid of simulations and experiments, this dynamic competition was demonstrated to be highly dependent on temperature variation. The enhanced self-healing ability of Li at elevated temperatures plays a positive role in suppressing the Li filament growth. The heat therapy improved the cell's cycle life, which provided insight into suppressing the Li filament growth. Operando SANS with high Li sensitivity provides a platform for investigating Li filaments in SEs.

Abstract:

Solid oxide cells represent one of the most efficient and promising electrochemical technologies for hydrogen energy conversion. Understanding and monitoring degradation is essential for their full development and wide diffusion. Techniques based on electrochemical impedance spectroscopy and distribution of relaxation times of physicochemical processes occurring in solid oxide cells have attracted interest for the operando diagnosis of degradation. This research paper aims to validate the methodology developed by the authors in a previous paper, showing how such a diagnostic tool may be practically implemented. The validation methodology is based on applying an a priori known stress agent to a solid oxide cell operated in laboratory conditions and on the discrete measurement and deconvolution of electrochemical impedance spectra. Finally, experimental evidence obtained from a fully operando approach was counterchecked through ex-post material characterization.
