Abstract

The invention relates to a positive charge storage material for all-solid-state electrical energy storage devices, which is mainly a pyrazoline derivative with a high positive charge transfer rate. Through introducing substituent groups into pyrazoline molecules, the properties such as positive charge transfer rate and the like of the positive charge storage material are improved, thereby improving the working properties of devices. According to the invention, through applying a pyrazoline derivative, namely, a positive charge storage material to an all-solid-state electrical energy storage device, an energy storage device which is high in energy density and power density, environmental-friendly and high in safety is obtained.

Description

field of invention [0001] The invention relates to an energy storage material, in particular to an all-solid-state electric energy storage device using pyrazoline derivatives as positive charge storage materials. Background technique [0002] With the development of global industrialization, the energy issue has become increasingly prominent and has become a bottleneck restricting the development of the world economy. To this end, countries have formulated energy technology development strategies, vigorously developed new energy storage equipment, and made full use of existing energy. Traditional energy storage materials such as batteries and capacitors have played an important role in the field of energy storage. Batteries generate charges through electrochemical reactions and store electrical energy. It takes a certain amount of time to charge or discharge. The battery has a high energy density but a low power density. In recent years, research on high-performance lithiu...
