“…Although Li plating has been overwhelmingly considered the culprit of fast charge problems, it was found that even if the potential of the graphite anode never drops below 0 V vs. Li/Li + during 10 C‐charging in power‐optimized Gr/NCA cells, the accelerated performance degradation is still unavoidable. Similarly, Mussa et al reported that energy‐optimized batteries (25 Ah, Gr/NMC111) release large amounts of gas, accompanied by severe graphite exfoliation, as the batteries are charged at 4 C. The above results point to the fact that under fast charge, the existing SEI on the graphite anode is unable to protect electrolyte solvents from electrochemical reduction. This is yet another issue for fast charge resulting in electrolyte depletion, impedance growth, and battery swelling.…”

Long charging time for Li‐ion batteries is a critical obstacle for the widespread adoption of electric vehicles, especially when compared with the rapid refueling of traditional internal combustion engine vehicles. Fast charging results in accelerated performance degradation and low energy efficiency for Li‐ion batteries. The batteries adopted in the present electric vehicle market are mainly based on chemistry consisting of a graphite anode and a layered lithium transition‐metal oxide cathode. The fast‐charging capability of such batteries is limited by Li plating on the graphite anode and structural instability of the layered lithium transition‐metal oxide cathode. In this Minireview, the challenges and possible solutions to these fast charge problems are reviewed at both the materials and cell levels.

“…The C-rate defines the maximum charging and discharging current with regard to the battery capacity. Higher charging rates (e.g., between 1 C and 4 C) can cause lithium plating, increasing impedance, and promoting a reduction in cell capacities [49,64]. As a result, lithium-ion batteries can age faster [64].…”

A variety of measures are currently being taken on both the national and international levels in order to mitigate the negative effects of climate change. The promotion of electric mobility is one such measure for the transport sector. As a key component in a more environmentally-friendly, resource-saving, and efficient transport sector, electric mobility promises to create better sustainability. Several challenges still need to be met to exploit its full potential. This requires adapting the car technology, the value chain of vehicles, loads on the electricity network, the power generation for the drive, traffic, and charging infrastructure. The challenges to this endeavor are not only technical in nature, but they also include social acceptance, concerns, and economic, as well as ecological, aspects. This paper seeks to discuss and elucidate these problems, giving special focus to the issues of driving range, phenomenon of range anxiety, charging time, and complexity of the charging infrastructure in Germany. Finally, the development of social acceptance in Germany from 2011 to 2020 is investigated.

“…4 An electrolyte additive that can regulate Li metal electrodeposition and stabilize the plated Li metal is highly demanded for mitigating the Li plating related problems. Even without Li plating, the Li-ion cells under fast charge are still subject to rapid capacity fade because the SEI cannot effectively prevent electrolyte solvents from reductive decomposition at the anode 6 and protect graphite from structural exfoliation 50 as a result that the SEI fails to block the solvated Li + ions from permeating to the SEI-electrode interface. 51 Therefore, the chemical and electrochemical compatibility with the other electrode must be considered in the design of a new electrolyte additive or an additive combination.…”

The electrolytes of Li-ion batteries consist mainly of a LiPF 6 salt dissolved in a carbonate-based solvent mixture. Such electrolytes cannot support fast charge without detrimental impacts on performance and lifetime. Fast charge aggravates parasitic reactions of the electrolyte solvents and structural degradation of the lithium layered transition metal oxide cathode materials. This leads to not only the depletion of electrolyte solvents but also the loss of cyclable Li + ions, accompanied by impedance growth and volumetric swelling of the battery. In this perspective, the design aspects of the electrolytes for fast charge of Li-ion batteries are discussed and proposed.
