Due to the economic benefits and environmental awareness, most of the battery manufacturing industries in India are interested to redesign their existing supply chain network or to incorporate the effective closed loop supply chain network (CLSCN). The purpose of this paper is to develop CLSCN model with eco-friendly distribution network and also enhance recycling to utilize recycled lead for new battery production. The existing CLSCN model of a battery manufacturing industry considered for case study is customized for attaining economic benefit and environmental safety. Hence, single objective, multi-echelon, multi-period and multi-product CLSCN model with centralized depots (CD) is developed in this work to maximize the profit and reduce the emission of CO₂ in transportation.

The proposed CD has the facility to store new batteries (NB), scrap batteries (SB) and lead ingot. The objective of the proposed research work is to identify potential location of CD using K-means clustering algorithm, to allocate facilities with CD using multi-facility allocation (MFA) algorithm and to minimize overall travel distance by allowing bidirectional flow of materials and products between facilities. The proposed eco-friendly CLSCN-CD model is solved using GAMS 23.5 for optimal solutions.

The performance of the proposed model is validated by comparing with existing model. The evaluation reveals that the proposed model is better than the existing model. The sensitivity analysis is demonstrated with different rate of return of SB, different proportion of recycled lead and different type of vehicles, which will help the management to take appropriate decision in the context of cost savings.

This research work has proposed single objective, multi echelon, multi period and multi product CLSCN-CD model in the battery manufacturing industry to maximize the profit and reduce the CO₂ emission in transportation, by enhancing the bidirectional flow of materials/products between facilities of entire model.

The purpose of this study is to develop a holistic optimization model for an integrated sustainable fleet planning and closed-loop supply chain (CLSC) network design problem under uncertainty.

A novel mixed-integer programming model that is able to consider interactions between vehicle fleet planning and CLSC network design problems is first developed. Uncertainties of the product demand and return fractions of the end-of-life products are handled by a chance-constrained stochastic program. Several Pareto optimal solutions are generated for the conflicting sustainability objectives via compromise and fuzzy goal programming (FGP) approaches.

The proposed model is tested on a real-life lead/acid battery recovery system. By using the proposed model, sustainable fleet plans that provide a smaller fleet size, fewer empty vehicle repositions, minimal CO₂ emissions, maximal vehicle safety ratings and minimal injury/illness incidence rate of transport accidents are generated. Furthermore, an environmentally and socially conscious CLSC network with maximal job creation in the less developed regions, minimal lost days resulting from the work's damages during manufacturing/recycling operations and maximal collection/recovery of end-of-life products is also designed.

Unlike the classical network design models, vehicle fleet planning decisions such as fleet sizing/composition, fleet assignment, vehicle inventory control, empty repositioning, etc. are also considered while designing a sustainable CLSC network. In addition to sustainability indicators in the network design, sustainability factors in fleet management are also handled. To the best of the authors' knowledge, there is no similar paper in the literature that proposes such a holistic optimization model for integrated sustainable fleet planning and CLSC network design.

BATTERIES to provide a vital source of standby power, in the event of engine failure, are carried by virtually all aircraft, and one of the major suppliers of these batteries for many years has been Chloride, using also the brand names Exide and Dagenite. Some of the company's latest developments in aircraft batteries are described.

Most of this concluding article is concerned with surveying the corrosion of lead and its alloys in acids and alkalis of all types. As a considerable proportion of the lead consumed each year by industry is used for making grids for lead‐acid batteries, special attention has also been given to corrosion problems in this field. The newer applications for lead include its use in nuclear energy plant as a shielding material, and as a reactor coolant, and the corrosion problems arising under such conditions are discussed.

After completion of the case study, the students will be able to analyze the role of industry in strategic decision-making, examine the information and make judgments with the use of different models such as political, economic, social, technological, environmental & legal (PESTEL) and Porter’s five forces and formulate a marketing strategy for the future move of Diwan & Co. using the Company, Competitors, and Customers (3Cs) model.

This case study is about young entrepreneur Mr Mansha Ram, who was working in the battery industry and was contemplating launching a new product. A gap was found after extensive research. The research showed that there is a gap between sustainable, reliable and cost-efficient batteries in the market that must be filled. To discuss this opportunity, a meeting was called where all managers talked about their concerns, considering the cost constraint as well as shifts in Pakistani battery industry trends. Ram was a key person who had to decide whether to launch the product or not. Should he go for a new initiative and launch lithium-ion batteries or capitalized on existing technology, which was lead acid batteries? Which path should he take considering all the macroenvironmental factors, electric vehicles or renewable energy?

This case study can be taught in the final year of undergraduate classes and the first year of MBA classes. This case study is particularly designed for students to understand how a company makes decisions while keeping in view the macro- and microbusiness environment. Even if some businesses do not have cost constraints, these businesses still face the impact of other factors on their businesses, for that purpose, the case study will provide insights into why a comprehensive industry analysis is important. Furthermore, this case study keeps in view the competitiveness of the market and its impact on the decision-making of companies.

This paper aims to forecast technological change for laptop batteries. The most promising technology to replace laptop batteries emerging today is micro fuel cells.

The authors use several sources of technical data like the Department of Energy Sandia National Laboratory Technical Library for exploring this topic further. Patents were searched for fuel cell and lithium battery development and to perform a technology cycle time analysis, identify countries filing patents, and discover what areas they are working on development.

Based on the analysis, fuel cells promise to be the technology that will replace laptop lithium batteries.

This paper attempts to draw a framework bringing different scientific data sources together for technology forecasting.

THE aviation market is a complex and critical one for the battery manufacturer. Not only does he have to take into account the demands that are likely to be placed on his batteries, but he also has to persuade the customer of the suitability of his particular generic battery couple — whether it be lead acid or nickel‐cadmium.

With the UK’s accelerating plans to transition to electric mobility, this paper aims to highlight the need for policies to prepare for appropriate management of electric vehicle (EV) lithium-ion batteries (LIBs) as they reach the end of their life.

This is a regulatory review based on projections of EV LIBs coming off the market and associated problems of waste management together with the development of a servitisation model.

Circular economy in EV LIBs is unlikely to shape itself because LIB recycling is challenging and still in development. LIB volumes are insufficient for recycling to be currently profitable, and a circular economy here will need to be driven by regulatory intervention. Ignoring the problem carries potentially high environmental and health costs. This paper offers potential solutions through new EV ownership models to facilitate a circular economy.

The authors suggest a new EV ownership model. However, despite environmental benefits, re-shaping the fundamentals of market economies can have disruptive effects on current markets. Therefore, further exploration of this topic is needed. Also, the data presented is based on future projections of EV markets, battery lifespan, etc., which are uncertain at present. These are to be taken as estimates only.

The paper proposes regulatory interventions or incentives to fundamentally change consumer ideas of property ownership for EVs, so that EV automotive batteries remain the property of the manufacturer even when the consumer owns the car.

This case study relates to a real-life situation the data was collected from primary and secondary sources between 2012 and 2013. The case is of a company Pakistan Accumulators (PAL), having less than 18 years of experience, has been able to grow successfully in the dynamic environment of Pakistan. The decline of the private businesses in Pakistan due to the energy crisis has popped up a new need of power generation alternative equipment in the country. PAL, which is a privately owned company, suppliers of automotive batteries, Uninterruptable Power System (UPS) batteries, lead acid batteries and rechargeable batteries has been able to manage the growth of 20 per cent per year. In this case study, we have highlighted only one market segment of the company that is of UPS batteries, we have focused on what is the future prospect of this particular segment, its attractiveness. Also, the area of focus was the new market segments which can be targeted by the company. Basic issues of the case study: calculation of the market segment value of UPS industry; identification and solution of different challenges faced by PAL in the dynamic Pakistani market (contingency theory); recognition of different future growth prospects for PAL.

The basic objective of this case is to enhance the analytical and qualitative skills of the students by giving them the real-life perspective of a company working successfully in country like Pakistan which is facing economic and political crises. This case can also be used for understanding the problems of third-world markets and how company can pursue successfully in the long–term.

The purpose of this paper is to describe a two‐level hierarchical control strategy for electrical energy transfers in multisource renewable energy systems. The aim of the control design is to perform the energy transfers, according to the sources power variations and the load characteristics.

The controller determines the operating mode of the multisource renewable energy system and the power ratio provided by each source to satisfy the load demand. The study is based on an accurate model of the DC/DC converters coupled on the DC bus. The performance of the controller is compared with the usual method based on the measurements of the system variables with sensors (solar radiation, shaft speed, voltages, and currents).

The proposed method does not need extra sensors to measure the available power for each source.

The method is developed for an hybrid system with two sources (photovoltaic and lead‐acid battery bank) and specific zero voltage switch full‐bridge isolated buck DC/DC power converters but can easily extended to more sources and other classes of DC/DC converters.

The method is assessed through computer simulations using a simple comprehensive model. An experimental device is also developed by the GREAH Research Group of University Le Havre (France). The GREAH also participates to a technologic centre with similar topology on the site of Fecamp (France).

The proposed autonomous control schema is suitable to control hybrid systems with several energy sources in remote areas.

The main contributions of this work are first to introduce a two stages controller and second to use the duty cycle value of the power converters as decision criteria to switch off/on the sources.
