Novel solid polymer electrolyte for high voltage energy storage devices.

在少量离子液体（IL）作为增塑剂存在的情况下，通过三维自组装，我们成功地制造了一种无泄漏/无蒸汽，不易燃的固体电解质，在晶体中，混合二氧化硅颗粒（PSiPs）与离子液体聚合物的“浓缩”聚合物刷（CPBs）。凝固和离子传导是由于psip的规则排列，从而在核心之间产生高离子导电性的网络路径，其中含有适量的离子液体作为增塑剂。从这个角度来看，这与之前报道的用纳米颗粒增强的电解质完全不同，纳米颗粒在其中处于无定形状态，而不是晶体状态。CPB不仅在形成这种高阶有序结构方面起着重要作用，而且在增强离子传导方面也起着重要作用。首先，本文描述了这种新型固体电解质的结构和性能，验证了它是一种高度有序的结构，即面立方（fcc）晶体，离子电导率高，离子自扩散能力大大提高。值得注意的是，它在固体聚合物电解质中具有最高的导电性。此外，本文还首次成功应用于双极性锂离子可充电电池，该电池在室温下工作，具有双工作电压和mAh水平的容量。这将为开发下一代安全的电化学装置开辟一条新的途径。

We successfully fabricated a leak/vapor-free, non-flammable and solidelectrolyte by three-dimensionally self-assembling, in a crystal, the hybrid silica particles (PSiPs) with “concentrated” polymer brushes (CPBs) of ionic-liquid polymers in the presence of a small amount ofionic liquid (IL) as a plasticizer. Solidification as well as ionic conduction are owing to the regular arrayof PSiPs thereby producing, between cores, a high ion-conductive, networked path containing anappropriate amount of ionic liquid as a plasticizer. From this point of view, this is completely differentfrom the previously reported electrolyte reinforced with nano particles, which are in an amorphous statein it but not in a crystal one. The CPB plays an important role not only in forming such higher-orderstructure but also in enhancing the ionic conduction. First of all, this paper describes the structure andproperties of this new solid electrolyte, verifying a highly ordered structure, that is the face-c ntered cubic (fcc) crystal, as well as high ionic conductivity lined with much improved self diffusion of ions. It shouldbe noted that it achieved the highest level in conductivity among solid polymer electrolytes. In addition,this paper demonstrates its first successful application to a bipolar lithium-ion rechargeable battery operated at room temperature with a double operation voltage and a capacity at a level of mAh. It wouldopen a new route to develop safe electrochemical devices for next generation.
