Abstract

Purpose

The purpose of this study is to, first, provide an overview of the previously conducted works related to thermal analysis of space equipment, including battery packages, especially lithium (Li)-ion ones. Second, the need for a reduced thermal mathematical model (RTMM) and a procedure devising it is defined. Finally, an experimental steady-state temperature distribution test is conducted to finalize the RTMM study.

Design/methodology/approach

This study was carried out as part of a development project for thermal analysis of Li-ion battery packages used in a space equipment. The study presents certain stages of the design of the battery pack in parallel with battery technology development. Following a literature review, a numerical thermal analysis is conducted; then interface thermal conductance values are found out by means of the first law of thermodynamics; and the study is completed with the help of an experimental test.

Findings

The study provides key aspects for a successful battery-package thermal design for a space equipment. Additionally, the study summarizes the experimental results used in the RTMM process and the computed thermal conductance values between node couples.

Practical implications

Thermal analysis is important and vital in space equipment considering their harsh working conditions and environments. Hence, the study provides a RTMM for the thermal analysis of Li-ion battery packages, instead of a full finite element model, to save computational time and CPU usage. The findings are supported by experimental results. Hence, presented details can be used as guidelines for enterprises having a goal of battery package technology achievement, including design and manufacturing.

Originality/value

After providing a literature review of studies conducted on satellite subsystems including Li-ion batteries, this study presents a clear, complete and verified process of a RTMM for a Li-ion battery package in aero/space structures design. It presents details of building up a model and calculation methodology through an iterative procedure in which an optimization algorithm known as particle swarm optimization (PSO) was benefitted. In the RTMM, additionally, experimental temperature distributions obtained through thermal vacuum test were presented. It has been shown that the model can be used reliably in designing space equipments.

Abstract

Purpose

Interest in battery energy storage systems (BESS) is high, and technologies such as Li-ion (and other advanced chemistry) batteries in specific use cases are already economically viable. In this paper, the authors build further on the authors' previously published paper1 to estimate the potential positive impact that accelerated adoption of Li-ion batteries for stationary storage per the authors' identified already economically viable use cases, can have both on India's macro-economy and current account deficit as well as in helping meaningfully accelerate circular economy and Sustainable Development Goals (SDG) benefits of green economy transition.

Design/methodology/approach

The authors identified key challenges for development of BESS ecosystem and applied quantitative and qualitative assessment methodology for rapid adoption of BESS in India. The authors' study was validated through interviews with stakeholders and the authors summarize applicable findings for emerging countries such as India to encourage faster, wider adoption of energy storage.

Findings

The authors' study provides key policy recommendations to achieve a better balance in policy focus—not only for electronic vehicles (EVs) and utility-scale storage, but also for stationary behind-the-meter storage through key policy measures including placing a CESS on diesel generators (DGs), differential tariffs, encouraging advanced battery imports as a way to reduce crude oil imports, green financing and investments in de-carbonized energy breakthrough technologies (e.g. gravity-based energy storage systems). The authors recommend key technology priorities and strategic business rationale for private sector efforts by developing competitive advantages for non-battery hardware and software and expanding into emerging markets, with potential US$15–20+bn enterprise value.

Originality/value

While the dominant discourse focuses on EVs and utility scale applications of storage, the authors' paper shows the larger near term opportunity for impact is in stationary storage that too in end-user adoption use cases.

Abstract

Purpose

The purpose of this paper is to conduct the synthesization of LiFePO4-C (LFP-C) with fine particle size and enhanced electrochemical performance as the positive electrode material for Li-ion capacitors (LICs) with neutral aqueous electrolyte.

Design/methodology/approach

LFP-C was prepared by using polyethylene glycol (PEG) as a grain growth inhibitor, and the effects of the calcination temperature and PEG content on the structure and morphology of LFP-C were investigated. LICs using environment-friendly, safe and low-cost LiNO3 aqueous electrolyte were assembled with LFP-C as the positive electrode and active carbon as the negative electrode. The electrochemical performances of LFP-C and LICs were studied.

Findings

The results show that the particle size of LFP-C decreases significantly through the introduction of PEG. Cyclic voltammetry results show that the LFP-C prepared at 550°C with 1.0 g PEG exhibits the highest Cpe of 725 F/g at the scanning rate of 5 mA/s. Compared to LFP prepared without PEG, the electrochemical performance of optimized LFP-C dramatically increases due to the decrease of the particle size. Moreover, the LIC assembled with the optimized LFP-C exhibits excellent electrochemical performances. The LIC maintains about 91.3 per cent of its initial Cps after 200 cycles which shows a good cycling performance.

Research limitations/implications

The LFP-C is the suitable positive electrode material for LICs with neutral aqueous electrolyte. LICs can be used in the field of automobiles and can solve the problems of energy shortage and environmental pollution.

Originality/value

Both the LFP-C with fine particle size and its optimal LIC using environment-friendly, safe and low-cost LiNO3 aqueous electrolyte own good electrochemical performances.

Abstract

Purpose

Gas evolution within lithium-ion batteries (LIBs) gives rise to safety concerns that question their applicability. The gas evolution is not only the result but also the inducement of performance deterioration of LIBs. In this paper, the growth characteristics and dynamic behavior of gas bubble on the electrode surface are studied, and the interference mechanism of gas evolution on Li-ion diffusion or Li-ion conduction within LIBs is discussed and validated by the numerical simulations.

Design/methodology/approach

First, the mathematical models and simulation method are established. The growth and flow of gas bubble in the serpentine channel on electrode surface, which results from the gas-liquid flow and the effects of surface tension, is modeled by using the multi-phase Navier-Stokes and the volume of fluid method. Integrating Butler–Volmer and Fick’s law, the mathematical model of ions transport in the electrochemical cell is set-up. Second, the motion of gas bubble is tracked, and the variations of bubble shape and characteristic parameters with time are obtained by the computed fluid dynamics (CFD) method.

Findings

Based on the CFD results, the battery models and electrochemical simulations are carried out to analyze the ionic transport characteristics. The results show that the microstructural morphology such as the serpentine channel shape and size on electrode surface are important aspects for the gas bubble growth and the local ionic transport. Li ions significantly accumulate at one side of the gas obstacle, hindering the ionic diffusion normally. When the gas bubble blocks the electrolyte, the passage of ions from the positive to the negative is interrupted, and the open circuit zone of the electrochemical cell is formed.

Originality/value

The gas evolution within LIBs is not only a result but also an inducement of its performance deterioration. The primary issues in this study are the growth characteristics and dynamic behavior of gas bubble on the electrode surface, providing the knowledge for the interference mechanism of gas evolution on ionic transport and ultimately leads to significant increase of battery resistance.

Abstract

Purpose

To focus on the development of negative materials with a large Li ion capacity.

Design/methodology/approach

All calculations were performed using the Own N‐layered Integrated molecular Orbital and molecular Mechanics method with Becke 3‐parameter, Lee, Yang, Parr for high‐level treatment and with the universal force field for low‐level treatment.

Findings

It was found that boron substitution created an electron acceptor level in a lower energy region than that for the pristine carbon. So that the Li absorption energy for the boron‐substituted cluster was much larger than that for the pristine carbon. Moreover, with the increase of the concentration of boron, adsorption energy increased considerably all cases.

Research limitations/implications

Two Li ions in the centre of the model were considered. Li ions of quantity 4, 6, 8, etc. could also be considered.

Practical implications

The method developed provided a simple and practical solution to development of negative materials with a large Li ion capacity.

Originality/value

The finding that with the increase of the concentration of boron, adsorption energy increased considerably in all cases.
