“…Comparing these results with [15] we can see that the CCCV charging needed 97 min and the pulsed-CV at 50% duty cycle achieved 82 min for both 50 Hz and 1 Khz, the pulsed charging is 15 min faster than CCCV. What is interesting is that battery capacity did not degrade much with the pulsed charging compared to CCCV profile, which makes the pulsed charging more suitable than CCCV for battery fast charge.…”

“…Another known charging method is the pulse charging like discussed in [14] where using a 50% duty cycle at 1 Hz, the cycle life was improved by 4 times and charging time reduced by 17% compared to the CCCV charging protocol. Kannan and Weatherspoon [15] used a Li-ion cell with Nickel Manganese Cobalt Cathode with a slightly different method, pulsed-CV, and charged the cell at frequencies of 50 Hz, 100 Hz and 1 kHz. The reduced charging time is between 14 min and 23 min, and the charging time using pulsed-CV has not changed a lot over the 250 cycles, whereas for the constant current constant voltage method, the charging time increased suddenly after 125 cycles.…”

The renewable solar energy industry and electric vehicle industry are today seeking for fast battery pack recharging methods to achieve higher performances, and fast energy recovery for energy storage systems (ESS) and for electric vehicles. The charge rate of batteries impacts directly the temperature which in turn impacts the capacity fade, thus it should be kept low to prevent the cells from warming up. This not only limits the charging rate but also puts us on a trade-off, a long lifetime or a fast recharge. In this study, we tried to achieve fast charging using a new charging method that combine two charging methods, without much deterring the capacity of the battery, in order to be able to maintain a long battery lifetime. Charging time of around 82 min was achieved for a 1.8 Ah battery. We compared our findings with the literature with known charging profiles.

The increasing integration of renewable energy sources (RESs) and the growing demand for sustainable power solutions have necessitated the widespread deployment of energy storage systems. Among these systems, battery energy storage systems (BESSs) have emerged as a promising technology due to their flexibility, scalability, and cost-effectiveness. This paper aims to provide a comprehensive review of the diffusion and deployment of BESSs across various applications, analyzing their impact on grid stability, renewable energy integration, and the overall energy transition. The paper examines the key drivers and challenges associated with BESS adoption, as well as market trends influencing their proliferation. Through an analysis of empirical data, this study aims to shed light on the current state of BESS diffusion. Finally, this research contributes to the knowledge base surrounding battery storage technology and provides insights into its role in achieving a sustainable and reliable energy future.

“…Advanced charging protocols, e.g., pulse current (PC) charging, hold the potential to prolong the service life of current LIBs. [6,7] Specifically, PC charging with relaxation has been extensively employed in electrochemical testing of NMC/Graphite, [8][9][10] LiFePO 4 (LFP)/Carbon-based, [11,12] LiCoO 2 (LCO)/Graphite, [13] and LFP/Li [14] batteries from lab cells to commercial batteries. A typical PC charging protocol consists of a constant current (CC) charging step followed by a relaxation period., and the durations of the charging and following relaxation periods vary depending on the experimental design.…”

The key to advancing lithium‐ion battery (LIB) technology, particularly with respect to the optimization of cycling protocols, is to obtain comprehensive and in‐depth understanding of the dynamic electrochemical processes during battery operation. This work shows that pulse current (PC) charging substantially enhances the cycle stability of commercial LiNi0.5Mn0.3Co0.2O2 (NMC532)/graphite LIBs. Electrochemical diagnosis unveils that pulsed current effectively mitigates the rise of battery impedance and minimizes the loss of electrode materials. Operando and ex situ Raman and X‐ray absorption spectroscopy reveal the chemical and structural changes of the negative and positive electrode materials during PC and constant current (CC) charging. Specifically, Li‐ions are more uniformly intercalated into graphite and the Ni element of NMC532 achieves a higher energy state with less Ni─O bond length variation under PC charging. Besides, PC charging suppresses the electrolyte decomposition and continuous thickening of the solid‐electrolyte‐interphase (SEI) layer on graphite anode. These findings offer mechanistic insights into Li‐ion storage in graphite and NMC532 and, more importantly, the role of PC charging in enhancing the battery cycling stability, which will be beneficial for advancing the cycling protocols for future LIBs and beyond.
