Abstract With the rapid increase in the decommissioning of the EV Li-ion batteries (EV-LIBs), the EV-LIBs recycling industry is growing dramatically. Based on the realistic supply relationship data of major firms in the EV-LIBs recycling industry, this paper uses the complex network theory to construct a global firm-level EV-LIBs recycling supply chain (EV-LIBs-RSC) network and analyze the structural characteristics of the EV-LIBs-RSC network from the network level. Specifically, The degree distribution, average degree, overall density, average shortest path length, and community structure of EV-LIBs-RSC network are systematically analyzed. The relevant results can assist the government in proposing appropriate industrial policies.

Technological Improvements

Lithium ion batteries are experiencing an increased success thanks to their interesting performances, in particular for electric vehicles applications. Their continuous technological improvements in the last years are providing higher energy density and lower manufacturing costs. However, the environmental performance of their supply chain is of paramount importance to guarantee a cleaner alternative to fossil-based solutions on the entire life cycle of the applications. This paper carries out a comprehensive review on the main aspects related to Li-ion batteries manufacturing, to support the readers in understanding the complexity of the subject and the main challenges and opportunities for the future developments of this technology. The paper discusses the expected future demand of batteries; the main aspects related to the supply chain, including existing assets, input materials and alternative technologies; the end-of-life of batteries; the environmental impacts; and the main geopolitical implications.

Synthetic Approaches

Being inherently safe and chemically compatible with the electrolyte, lithium titanate is considered alternatives to carbonaceous anodes in Li-ion batteries. Given the commercial success of the spinel lithium titanate, carbon coated lithium titanate, particularly in nano structured forms, have been fabricated and investigated for the applications. Nano structuring leads to increased reaction areas, shortened Li+ diffusion and potentially enhanced solubility/capacity. This paper reviews structural characteristics and electrochemical reactivity, along with synthetic approaches of carbon coated nanostructures and nano-composites based on lithium titanate, recently.

Reasonable and strong structure is an important foundation for the smart transmission grid. For vigorously promoting construction of the smart grid, it is of great significance to have a thorough understanding of the complex structural characteristics of the power grid. The structural characteristics of several actual large-scale power grids of China are studied in this paper based on the complex network theory. Firstly, the topology-based network model of power grid is recalled for analyzing the statistical characteristic parameters. The result demonstrated that although some statistical characteristic parameters could reflect the topological characteristics of power grid from different ways, they have certain limitation in representing the electrical characteristics of power grid. Subsequently, the network model based on the electrical distance is established considering the limitation of topology-based model, which reflects that current and voltage distribution in the power grid are subject to Ohm's Law and Kirchhoff's Law. Comparing with the topology-based model, the electrical distance-based model performs better in reflecting the natural electrical characteristic structure of power grid, especially intuitive and effective in analyzing clustering characteristics and agglomeration characteristics of power grid. These two models could complement each other.

Evaluation Matrix

The paper tries to add the network structure factors of agile supply chain network into agility evaluation. The paper firstly presents three concepts including node strength centrality, betweenness centrality, and network centrality. They are used to calculate the weight of node enterprises in the agile supply chain network. And then, a series of agility indicators are designed to evaluate agility of agile supply chain network. AHP is used to calculate the weight of the indicators. Next, these indicators are used to get initial agility evaluation matrix by means of Delphi method, Data Mining, and so forth. Then FCE is used to calculate the membership degree on agility of node enterprises by combining the evaluation matrix with the weight of indicators. Last, the evaluation result of comprehensive agility of agile supply chain network is calculated on the basis of considering the weight of node enterprises. This method can reflect the effect which the network structure of supply chain network makes on the agility of the supply chain network. It is a complement to the current evaluation methods of agility.

With demand for the natural resources exceeds a certain threshold, it leads to a global ecological threat like the “Amphhan” catastrophe that had ravaged the eastern part of West Bengal during the month of February 2020 that resulted in the loss of lives and economic activity which is yet to be regained with its earlier momentum. The inflicted calamity has given a “blow” as well as “boost” to renewable energy sector that leads to greater seriousness on development of the energy storages devices/stations in the country. While India has already achieved 374 GW of total installed capacity of power generation in which the contribution from the thermal sector is about 62 per cent and that of the RP is about 22 per cent that comes to 90 GW as of today and 60 GW is under pipeline or under construction or under tendering process. The year 2020 is undoubtedly a year of change and the COVID-19 pandemic situation together with enforced lockdown in several parts of the country and even in globe has forced people to think differently to remain relevant against the New-Normal. In order to choose the sources of energy that does not cause pollution to the surrounding environment, the RET is the best and most favourable options to opt for along with the battery storage devices for making the power available throughout the day-long and even when the sun sets. Most of the batteries currently produced and used in our country is lithium-ion based and is mostly imported. To be on the self-reliant mode and moving towards “Atmanirbhar Bharat” through “Make in India” we need to have more and more indigenous manufacturer of Li-ion batteries. Good news is that 10 Indian companies have already procured manufacturing technology from DRDO and large scale production of indigenous Li-ion batteries is expected soon. The National Energy Mission of the Government of India has just rolled out with a focus on the Make in India and is envisioned to take all necessary formalities and policy decisions to be adopted to incentivise advanced energy storage manufacturing in India through the application of innovation and new technology options that are available. As a science communicator, the authors strongly opine that with the appropriate support from the Government of India through the policy decisions by the Niti Aayog, India will be one of the top markets for the energy storage adoptions and manufacturing and is another way forward to mitigate the climate change by producing electricity free from carbon dioxide emissions into atmosphere and provide green energy for sustainable path of development. As we see that the energy storage is a new thrust area along with introduction of FGD technology retrofitting with the thermal power plant, we look forward to the new ecosystem to be achieved by 2030.

The paper establishes the evolutionary mechanism model of agile supply chain network by means of complex network theory which can be used to describe the growth process of the agile supply chain network and analyze the complexity of the agile supply chain network. After introducing the process and the suitability of taking complex network theory into supply chain network research, the paper applies complex network theory into the agile supply chain network research, analyzes the complexity of agile supply chain network, presents the evolutionary mechanism of agile supply chain network based on complex network theory, and uses Matlab to simulate degree distribution, average path length, clustering coefficient, and node betweenness. Simulation results show that the evolution result displays the scale-free property. It lays the foundations of further research on agile supply chain network based on complex network theory.
