Energy storage materials electrochromic device

The development of high performance electrolytes is an important task in the production of devices for electric energy storage and delivery such as lithium ion batteries, capacitors, and electrochromic devices. Carbonate-based materials are one of the liquid electrolytes. Carbonate-based liquid electrolytes are now commonly used for the economical lithium ion batteries [31]. The solution of carbonate and lithium salts exhibits high ionic conductivity, on the order of 10-3 S cm-1 at ambient temperature. 

The field of electrode materials has been one of the earliest areas of applications of PTs. Initially envisioned in the perspective of energy storage, the field has heen progressively reoriented toward applications such as (bio)electrochemical sensors and electrochromic devices. Recently, the field of PT-based sensors has grown considerably and progressively evolved fi-om purely electrochemical systems to optical sensors based on absorption or luminescence processes. 

Abstract The development of new materials that can be apphed as solid electrolytes has led to the creation of modern systems of energy generation and storage. Among different poly(ethylene oxide)-based electrolytes, natural polymers, snch as hydroxyethylcellnlose, hydroxypropylcellulose or carboxymethylcellulose, starch and chitosan or proteins like gelatin, are also proposed. After salt or acid addition, the transparent membranes show ionic conductivity values of 10 S/cm and can be apphed with good stability results to electrochromic devices.
