This article reviews the PEO-based electrolytes for lithium-ion batteries.Poly(ethylene oxide) (PEO) based materials are widely considered as promising candidates of polymer hosts in solid-state electrolytes for high energy density secondary lithium batteries. They have several specific advantages such as high safety, easy fabrication, low cost, high energy density, good electrochemical stability, and excellent compatibility with lithium salt. However, the typical linear PEO does not reach the production requirement because its insufficient ionic conductivity due to the high crystallinity of the ethylene oxide (EO) chains, which can restrain the ionic transition due to the stiff structure especially at low temperature. The scientists have explored different approaches to reduce the crystallinity hence to improve the ionic conductivity of PEO-based electrolytes, including: blending, modifying and making PEO derivatives etc. This review is focused on surveying the recent developments and issues about PEO-based electrolytes for lithium-ion batteries.

“…and the capacity retention of Li-ion batteries. [160] Ko et al further explored the poly[dimethylsiloxane-co-(siloxane-g-acrylate)] (PDMS-A) and lithium-modified silica nanosalt (Li 2 O 2 ) as electrolyte additives in low-temperature Li-ion batteries. They improved the electrochemical stability over 5.5 V, a capacity retention of 63.4% after 50 cycles at −20 °C for the cell (LiCoO 2 /graphite), compared to 38.7% without the additives.…”

Nowadays excessive consumption of fossil fuels due to population growth and industrial development induced serious energy and environmental crisis. To alleviate the ecological crisis and comply with the ever-increasing energy demand, developingThe electrolyte has been considered as a key factor toward higher energy density for Li-ion and Li-metal batteries. However, conventional electrolytes suffer from uncontrolled interfacial reactions and irreversible decomposition causing performance deterioration and potential safety hazard. Organosilicon compounds have attracted great interest as promising electrolyte components due to facile chemical modifications, low glass transition temperatures (T g ), superior chemical, and thermal stabilities. Considerable investigation efforts have been devoted to developing better overall performance of organosilicon-based electrolytes in the past few years. Herein, the recent research progress of organosilicon-based functional electrolytes for the development of liquid, gel, and solid state electrolytes in Li-ion and Li-metal batteries is summarized. Attention is devoted to various types of organosilicon such as silane, siloxane, polysiloxane, and polyhedral oligomeric silsesquioxanes in terms of molecular design, ionic conductivity, functions shown in batteries, thermal, chemical, electrochemical stability, safety, etc. The feasible strategies are also discussed that may promote the comprehensive electrochemical performances of organosilicon-based electrolytes in different types of electrolytes and batteries. Finally, the challenges facing organosilicon-based electrolytes and proposed their possible solutions are presented alongside promising development directions.

“…The other electrolytes they innovated can even discharge at −60°C (C/ 20 discharge rate) with more than 80% of capacity at room temperature. Kwang Man Kim and his colleagues (Kima et al 2014) tested three types of polydimethylsiloxane (PDMS)based grafted and ungrafted copolymers as additives to commerical standard liquid electrolyte to see if they can enhance the LiB performance at low temperature. They found PDMS-based additive can help liquid electrolyte solution keep stable and have good ionic conductivities at −20°C.Differeing from conventional liquid electrolyte, researchers at the University of California San Diego (Rustomji et al 2017), developed a breakthrough liquified gas electrolyte employing difluoromethane that has stable performace ove an wide temperature rang and enable electrochemical capacitors work from −78 to 65°C with an increased voltage, and helps a 4 V lithium cobalt oxide cathode together with lithium metal anodes to operate with excellent capacity down to −60°C.Becaue their electrolytes are made from liquefied gas solvents that makes it far more resistant to freezing than normal liquid one.…”

Electrical energy storage (EES) is crucial in energy industry from generation to consumption. It can help to balance the difference between generation and consumption, which can improve the stability and safety of power grid. Share of renewable energy generation and low emission energy utilization at consumption side can grow up via the development of EES technology, which could reduce the emission of Greenhouse gas in the whole energy chain. Nowadays, the usage of EES are becoming broader not only in normal environment but also in some harsh environment such as underground, space and very cold climate, which brings new challenges from energy storage element (cell) technology to system packaging technology. This paper reviewed the available energy storage technologies, and their special requirements and applications in harsh environment. More attentions were paid to the usage of EES in cold climate application both for transportation such as electric vehicles (EV), and stationary application including large/small scale energy storage located in cold area, where stable discharge/charge at temperature lower than −20°C are required. Finally, a comprehensive review of the current technology from cell level to package was presented, and possible directions for R&D in the future to widen the operation temperature range of battery were proposed.
