“…In addition, it is found that PVDF might react with the lithiated graphite or lithium metal at high temperatures (above 45 °C) to form LiF and unsaturated >CCF bonds with resultant heat release, leading to potential safety issues. [10,13] Especially when cycled at high C rates, the lithium-ion conductivity of graphite/PVDF electrode is not high enough to accommodate the fast intercalation of Li + ; the unsettled Li + would then deposit on the surface of graphite, leading to dead lithium and safety concerns.…”

Polymer binders as a critical component in rechargeable batteries provide the electrodes with interconnected structures and mechanical strength to maintain the electronic/ionic transfer during battery cycling. The conventional binders, such as polyvinylidene fluoride (PVDF), are not ideal candidates due to their relatively low adhesiveness, weak mechanical strength, and poor functionality for high‐energy‐density batteries with a thick electrode and/or a high‐capacity electrode. Nevertheless, the binder has not yet received the attention that reflects its importance in batteries. The requirements of high energy density batteries make essential the exploration of advanced polymeric binders, which possess particular functions. In this review, state‐of‐the‐art binder design strategies are sorted in terms of the challenges of various electrodes (anodes and cathodes for lithium ion batteries (LIBs) and sulfur cathodes for Li–S batteries), which have been commercialized or have the potential for practical cells. A deep insight into how the polymeric binders improve the cell performance and the design principle of new binders is also provided. Finally, a perspective on the direction of future binder development for high‐energy‐density batteries with long cycle life is presented.

“…It should be noted that the most efficient LiFePo4 batteries currently on the market have densities of 0.25 KWh/kg and 0.62 KWh/L respectively. Current research to improve battery performance focuses on the one hand on the nature and shape of the electrodes and on the other hand on the conductivity ionic of the electrolyte and the separator, for a larger storage capacity, more stability and larger operating temperature ranges [34]. In particular, the electrolyte can be liquid or solid.…”

“…Their discharge voltage is more stable and they present a lower fire risk. The technology is mature and has an average cost of between 6400 and 13,600e /ton, which places it among the cheapest on the market for current lithium batteries [34]. It can thus be estimated that a 20,000-ton (1600 evp) ship would require between 625 and 1250 MWh to travel 1000 km at sea and occupy the volume of 80 to 160 evp.…”

Global warming is causing a major ice retreat from the North Pole. From now on, this retreat allows almost permanent movement between East and West off the coast of the Russian Federation along the Northern Sea Route (NSR). For a long time, navigators have been trying to use this route which significantly reduced the distance between continents. The amount of freight that currently travels on the NSR will inevitably increase in the coming years. To reduce environmental risks, one possible option is not to supply ships with heavy fuel oil. The ships could then be electrically powered and navigate in stages from one port to another along the route to refuel for energy. This electrical energy can be produced on site from renewable energy sources. In this article, a first feasibility analysis is outlined, taking into account the tonnage constraints for navigating on a possible route for the NSR, the cost of energy production and the possible location of several ports of call. Under current economic conditions, the solution would not be profitable as it stands, but should become so at a later stage, which justifies starting to think about a future full electrification of navigation on the NSR, which will also contribute to the economic development of the Russian Federation northernmost regions.

“…[ 10–12 ] From these works, the application prospect of ASSBs has been restricted by some critical problems: 1) large resistance caused by poor contact and space charge layer generated in the interface inside the ASSBs; 2) the cell failure due to alkali metal dendrite growth; 3) poor interface stability between electrode and solid electrolyte (SE), which leads to inferior cycle performance of ASSBs. [ 1,13–16 ] Thus, the interface dominates the performance of ASSBs.…”

The interface is a critical factor of electrochemical performance for all‐solid‐state batteries (ASSBs). Comprehending the composition, structure, morphology, and their evolution in the interface during charge/discharge cycling is greatly important for the development and practical application of ASSBs. The characterization techniques are very crucial and powerful for investigating the interface properties of ASSBs. This review briefly describes how the interface is generated in ASSBs, and then emphatically summarizes some important advanced techniques used to characterize the interface in ASSBs. The principle, advantage, and application of the techniques in the interface investigation are systematically discussed. This review provides fundamental insights and perspectives for developing the characterization techniques to deeply understand the interfacial behaviors of ASSBs, which is valuable for accelerating the commercialization of ASSBs used in electronic devices, electric vehicles, and large‐scale energy storage.
