“…Silicone-based reagents have tended to yield polymer electrolytes with higher lithium cation transport numbers, 0.5 to 0.6 [22,27]. This may be a result of reduced affinity of PDMS-based polymer chains for lithium salts compared to other types of polymer discussed here [69].…”

Solid polymer electrolytes have been widely proposed for use in all solid-state lithium batteries. Advantages of polymer electrolytes over liquid and ceramic electrolytes include their flexibility, tunability and easy processability. An additional benefit of using some types of polymers for electrolytes is that they can be processed without the use of solvents. An example of polymers that are compatible with solvent-free processing is epoxide-containing precursors that can form films via the lithium salt-catalyzed epoxide ring opening polymerization reaction. Many polymers with epoxide functional groups are liquid under ambient conditions and can be used to directly dissolve lithium salts, allowing the reaction to be performed in a single reaction vessel under mild conditions. The existence of a variety of epoxide-containing polymers opens the possibility for significant customization of the resultant films. This review discusses several varieties of epoxide-based polymer electrolytes (polyethylene, silicone-based, amine and plasticizer-containing) and to compare them based on their thermal and electrochemical properties.

In this work we examine the influence of the type of silicon source material (two milled and two plasma enhanced chemical vapor deposition) on the electrochemical performance of silicon-based anodes for Li-ion batteries. The four representative Si sources were previously identified in literature but have never been compared side by side, which is critical to understanding the wide variation in performance reported for siliconbased electrodes. These particles display unique surface

“…Compared with ZABs, LIBs have a lower theoretical specific energy (260 Wh kg À 1 ). [31] The capacity of LIBs for current EVs, such as the Renault Twizzy, Hyundai Ioniq, Nissan Leaf and VW E-Golf, often range from 6 to 30 kWh. [32] Targets set by the United States Advanced Battery Consortium LLC for EVs require power supply voltages of 220 V-420 V with usable energy of 45 kWh.…”

Poly(acrylic acid) (PAA) is a promising polymer host to support alkaline electrolytes in Zn‐air batteries. Herein, precursors containing different concentrations of monomers, crosslinkers and additives such as zinc oxide in alkaline solution are polymerized to fabricate gel polymer electrolytes (GPEs) via one‐pot synthesis. The compositional effects of the GPEs on battery performance are evaluated and a more efficient cell design is demonstrated. With a vertical double air electrode configuration, ZABs using PAA‐based electrolytes show unprecedented performance including high specific energy (913 Wh kgZn−1), excellent cycling stability (at least 160 cycles at 2×10 mA cm−2) and high power density output (2×135 mW cm−2). The study represents a viable option to replace aqueous electrolytes for high performing ZABs.
