ABSTRACT

For applications that require the storage and conversion of large quantities of energy such as electric vehicles and renewable intermittent energy systems, batteries combining high energy density (kWh/kg), low cost (euros/kWh), high reliability and long service life are necessary. Among various technologies under development, “all solid” lithium-metal-polymer batteries are particularly promising. The difficulties of this technology lie in the use of lithium metal at the negative electrode and the development of a polymer electrolyte allowing operation at room temperature. Different strategies developed based on dry polymer electrolytes, plasticized electrolytes, gelled electrolytes and rubber electrolytes are presented in this article.
