This book was released on 2019 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid increasing consumption of fossil fuels since the industrial revolution has brought about environmental and ecological contamination and its depletion, thus, humankind must stop to utilize more clean and renewable energy such as solar, hydraulic power, wind power as alternative. In this case, an effective and efficient medium is a must since those sorts of renewable energy are difficult to be stored and utilized in a standard way. As the invention and improvement of battery, electrical power come up to be the chosen solution. Therefore, electrical vehicles are already commercialized for a long time and growing up rapidly, grabbing the market share from traditional Inner Combustion Engine vehicles. Among the various battery chemistries, Lithium-ion Batteries (LIBs) have acquire most of attention from both academia and industry. With a similar mechanism, Sodium-ion Batteries (SIBs) are acting as an alternative for LIBs for their low cost. However, the current battery performance cannot satisfy the market of electrical vehicle and consumer electronics, thus, energy density and power density as two of the crucial factors for battery performance must be enhanced. To address these issues, the anode of LIBs and SIBs need to be improved. In this dissertation, novel ideas for anode materials design were given, towards not only the current anode modification, but next generation anode production as well. With a high theoretical capacity of 2595 mAh g-1 from alloy reaction, phosphorus is one of the most promising candidates as next generation anode material for lithium/sodium ion battery. Nonetheless, it is suffering volume expansion (300% for LIBs and 500% for SIBs) and low conductivity during cycling, leading to sacrificed robustness of the electrode. Herein, we developed an efficient and effective high energy ball milling route to crystalline phosphorus within carbon matrix as anode material for LIB and SIB. The special structure offers many advantages: enhanced the conductivity; shortened distance for Li+ or Na+ diffusion; buffered volumetric expansion and more stable structure. Benefitting from the merits, the composite delivers a capacity over 1000 mAh g-1 for about 300 cycles at a specific current of 1 A g-1. Both half-cell and full cell cycling test show an 80% retention around 300th cycle. More essentially, crystalline phosphorus can be still found after many cycles. As-prepared material also delivered a high sodium capacity over 700 mAh g-1 over 300 cycles. For increasing utilization in electrical vehicles, the limitation of power density has become a severe issue for LIBs. Therefore, LIBs with advanced high rate performance is highly desirable. A major issue for developing high rate battery is the performance of anode as their sluggish intercalation kinetics. Herein, we provide a new strategy for advanced performance LIB anode design and its demonstration. To fabricate anode with both high energy and power density, two different materials with each character respectively were mixed to achieve the goal, meanwhile, they need to have different charge and discharge plateaus. As the redox plateaus of these materials are different, the electrochemical interaction will occur when they are being charged or discharged as composite, thus enhance the performance as anode for LIBs. Phosphorus-carbon composite and commercialized LTO were utilized to demonstrate this strategy. The current anode system in commercialized LIBs are difficult to be substituted in the near future because of their low charging potential which leads to a high energy density for full cell. In this case, the development of LIBs in EV are highly depends on modification of the current system in recent years. Therefore, we developed a new route for graphite anode improvement with the additive of Metal-organic Framework (MOF). With its special structure, open metal sites (OMS), MOF can immobilize the anion of electrolyte by forming coordination bond, thereby prevents the electrolyte from decomposition, so as to eliminate the byproduct and heat release. With these advantages from MOF additive, the graphite anode performance was improved a great deal especially fast discharging (full cell). And post-cycle characterization explores that MOF keeps higher crystallinity of graphite and lower down the decomposition of the electrolyte LiPF6.

Available in PDF, EPUB and Kindle. Book excerpt: Graphite is currently used as negative electrode material in commercial lithium-ion batteries. Unfortunately, this material suffers from a relatively low specific capacity (372 mAh.g-1). Its substitution by a conversion material with a higher specific capacity as ZnFe2O4 (1001 mAh.g-1) would be interesting to increase the capacity of lithium-ion batteries.The use of nanomaterials can also limit the volumetric expansion of the electrode during cycling and enhance lithium ions kinetics.ZnFe2O4 nanopowders were synthesized in the Nanometric Structures Laboratory at the CEA (Atomic Energy and Alternative Energies Commission) by laser pyrolysis. This flexible synthesis method allowed the production of zinc iron oxides nanopowders with different morphologies, depending on the chosen experimental parameters (precursors, choice of gases and flow rates). Electrochemical performances were then evaluated vs. metallic lithium at the Energy Lab of Nanyang Technological University. Fundamental lithium storage mechanisms for ZnFe2O4 oxide were investigated by operando characterizations (XRD and 57Fe Mössbauer) and compared with those of a ZnO/Fe2O3 mixture. This study was realized in collaboration with the Charles Gerhardt Institute (University of Montpellier).This works highlighted the promising electrochemical performances of a specific morphology of ZnFe2O4 nanoparticles, consisting in a bimodal size population of particles, and allowed the deeper understanding of the lithiation and delithiation reactions.

This book was released on 2022-07-08 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes in-depth theoretical efforts to understand the reaction mechanism of graphite and lithium metal as anodes for next-generation rechargeable batteries. The first part deals with Na intercalation chemistry in graphite, whose understanding is crucial for utilizing graphite as an anode for Na-ion batteries. The author demonstrates that Na ion intercalation in graphite is thermodynamically unstable because of the unfavorable Na-graphene interaction. To address this issue, the inclusion of screening moieties, such as solvents, is suggested and proven to enable reversible Na-solvent cointercalation in graphite. Furthermore, the author provides the correlation between the intercalation behavior and the properties of solvents, suggesting a general strategy to tailor the electrochemical intercalation chemistry. The second part addresses the Li dendrite growth issue, which is preventing practical application of Li metal anodes. A continuum mechanics study considering various experimental conditions reveals the origins of irregular growth of Li metal. The findings provide crucial clues for developing effective counter strategies to control the Li metal growth, which will advance the application of high-energy-density Li metal anodes.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Under the electrification of transportation and deep decarbonization of the energy infrastructure requirement, the development and deployment of the next-generation battery with fast-charging capability and high energy is one of the hottest topics among academic and industrial fields. Current lithium-ion batteries (LIBs) offer moderate energy density enabling limited driving range and take considerably longer to recharge than traditional vehicles. Fast charging and high-energy density batteries are the key requirements for the widespread economic success of electric vehicles., This dissertation focuses on the practical application of rechargeable lithium batteries by designing and synthesizing different kinds of polymers and electrolyte formulation. In Chapter 2, I synthesized a kind of Li ion affinity PEI branched polymer (N-poly) and added it into the graphite anode as the binder material. The N-poly-based polymer composite anode binder could greatly enhance the rate performance the cycle performance at high rate (3 C and 6 C). The functional polymer N-polymer was proven to be favorable for the fast-charging application. In Chapter 3, ionic liquids were chosen to formulate the advanced and nonflammable electrolyte for high-energy-density Li metal batteries due to the anion-rich in the electrolyte. In Li∥NMC811 coin cells, the cell with ionic liquid-based electrolytes could maintain over 175 cycling with 80% capacity retention. The special electrolyte structure could promote an anion decomposition on Li metal anode and lead to high CE and longer cycling life. In Chapter 4, I designed and synthesized a new Li ion affinity polymer based on the aza-crown ether for the artificial SEI layer on the Li metal anode surface had been. The so-formed artificial solid electrolyte interphase has excellent passivation, homogeneity, and mechanical strength, and could tune the Li plating and enable the LiF rich SEI layer thus effectively stabilizing the Li/electrolyte interface and preventing electrolyte decomposition on cycling. In Chapter 5, a facile method to achieve a large size of a kind of reactive polymer PFSPA coated separator in the air atmosphere had been developed. And the coated separator can elongate the cycling number from 65 cycles to 220 cycles. It is because the polymer PFSPA in separator can swell into the electrolyte, attach the lithium surface, and generate LiF after reaction with Li. It helps to form a quite effective SEI layer upon cycling in the carbonate-based electrolyte. Therefore, the work showed tremendous potential for practical application. I concluded this dissertation work in Chapter 6 and briefly discussed the possible future work.
