Ionic materials could achieve 50% higher energy density while costing less than...

•, brian wang

Ionic Materials received an investment from Hyundai Cradle. Ionic Materials has a polymer electrolyte that can make higher performing and safer solid-state batteries. Prototype batteries with Ionic Materials' solid plastic electrolyte can enable higher energy densities at low cost.

Properties of Ionic Materials polymer

Up to 1.3 mS/cm at room temperature
Lithium transference number of 0.7
High voltage capability (5 volts)
Can accommodate high loadings in the cathode
High elastic modulus
Low cost precursors
Stable against Lithium
Conducts multiple ions

Ionic Materials has a $3 million ARPA-E funded project – Novel Polymer Electrolyte for Solid State Lithium Metal Battery Technology

Project Innovation + Advantages: 

Ionic Materials will develop a lithium metal (not lithium ion) rechargeable battery cell that employs a novel solid polymer electrolyte that enables the world's first truly safe lithium metal rechargeable battery cell. Scientists at the City University of New York have found that Ionic Material's proprietary ionic conducting polymer is the most highly lithium conducting solid state polymer material ever measured (at room temperature).
