In addition, LIBs still suffer from high cost, limited durability, and poor safety. [3] As a consequence, an alternative rechargeable battery system is crucial to cope with the growing demands of electric vehicles. [4] The prior demand for a power battery is security. The conventional power batteries suffered from frequent combustion accidents. The ascending voltage of cathodes will lead to stability concerns. Most of the thermal runaway is triggered by the reaction derived from electrodes. [6] The decomposition of cathode materials releases heat and oxygen and will trigger the combustion of flammable organic electrolytes. However, the high-energy cathode is essential for an energy-dense battery. Hence the substitution of conventional organic electrolytes is feasible to both enhance the energy density and battery safety. [5,7] The replacement of organic liquid electrolytes (OLEs) with solid-state electrolytes (SSEs) provides a promising future for the large-scale application of lithium metal batteries (LMBs). SSEs with wide electrochemical stability windows and high modulus possess the potential to enable high-capacity electrode materials and prevent Li dendritic deposition. [8] Besides, the SSEs also possess good thermal stability, which enables a wide operation temperature range and avoid the combustion risk. The introduction of SSEs allows a simplified battery design and minimization of inactive materials, consequently increasing energy density at the cell-level. Moreover, the solid-state electrolytes enable the employment of Li metal anodes, which is considered as the most promising anode for next-generation rechargeable batteries due to its ultrahigh theoretical specific capacity of 3860 mAh g −1 and lowest negative electrochemical potential (−3.04 V vs the standard hydrogen electrode). [9] In conventional organic electrolytes, lithium metal suffers from the unstable solid-state interphase, dendrite penetration, and pulverization issues. [1c,10] The rapid deterioration of LMBs is attributed to the high reactivity of lithium metal. [11] Virtually most conventional OLEs can be reduced at the Li surface, forming unstable solid electrolyte interphase (SEI). During repeated charge-discharge cycles, Li tends to generate dendritic morphology because of nonuniform current/ion distribution. [12] Lithium dendrites normally lead to the fracture and regeneration of SEI, further aggravating the dendrite growth. [12a,13] The The scale-up process of solid-state lithium metal batteries is of great importance in the context of improving the safety and energy density of battery systems. Replacing the conventional organic liquid electrolytes (OLEs) with solid-state electrolytes (SSEs) opens a new path for addressing increasing energy demands. Advanced approaches have been validated in lab-scale cells, but only a few successful results can be applied on the practical scale. Herein, the battery systems enabled by SSEs are briefly reviewed and the difficulties and challenges for both lab-level cells and large-scale batteries from...

Recent Progress and Emerging Application Areas for Lithium–Sulfur Battery Technology

With the ever-increasing need for electrification across many application sectors, the development of new energy-storage technologies is of increasing relevance and critical importance. Electrification is progressing significantly within the traditional transportation sectors such as electric bikes, cars, buses, and other commercial vehicles, enabled by continued cell development and Gigafactory-scale mass production of Li-ion battery (LIB) technology. However, two key factors are starting to drive the need for new solutions to be found. One factor is the secure supply of key elements-mainly cobalt and nickelused in most of the conventional Li-ion cells which are becoming increasingly critical. The other is the performance requirements of desirable emerging application areas that are beyond the capabilities of traditional LIB technology. Examples include large commercial vehicles, [1] high-altitude long endurance (HALE), high-altitude pseudosatellites (HAPS), electric vertical takeoff and landing (eVTOL), [2] and electric passenger aircraft. The weight of the battery system (BSM) is an especially critical factor for these aviation applications. The battery systems' performance requirements differ across these applications: power, cycle life, system cost, etc. However, the need for a high gravimetric energy density, 400 Wh kg À1 and beyond, is common across them all. Higher energy battery systems will enable these vehicles to achieve extended range, a longer mission duration, lighter vehicle weight, or increased payload. In the following sections, key advantages, limitations, and progress made to extend cycle life, energy, power, and safety of Li-S battery management systems (BMS) are described. Further, recent advances regarding modeling, battery system management, and the integration of Li-S batteries into present as well as future real-world applications are summarized. 2. Lithium-Sulfur Battery Technology 2.1. Advantages LIB systems are the current technology of choice for many applications; however, the achievable specific energy reaches a maximum at around 240-300 Wh kg À1 at the cell level.

“…For this reason, we recommend harvesting electrodes from one cell and test them versus a reference electrode to later be used in the mechanistic model. Discussion on how to open commercial cells and perform half-cell testing is out of the scope of this paper and more details can be found in [29,[63][64][65][66][67][68][69]. Individual electrodes in half-cell should be tested with an RPT protocol similar to the one presented in Figure 5 but with more rates ranging from twice as low to twice as fast to enable simulation of loss of active material and kinetic changes [55].…”

Validation is an integral part of any study dealing with modeling or development of new control algorithms for lithium ion batteries. Without proper validation, the impact of a study could be drastically reduced. In a perfect world, validation should involve testing in deployed systems, but it is often unpractical and costly. As a result, validation is more often conducted on single cells under control laboratory conditions. Laboratory testing is a complex task, and improper implementation could lead to fallacious results. Although common practice in open literature, the protocols used are usually too quickly detailed and important details are left out. This work intends to fully describe, explain, and exemplify a simple step-by-step single apparatus methodology for commercial battery testing in order to facilitate and standardize validation studies.
