Hyundai invests in solid-state battery materials startup Ionic Materials to reduce battery costs

According to foreign media reports, Hyundai Motor Company's venture capital center-Hyundai CRADLE is investing in Ionic Materials, a private battery material developer located in Massachusetts, to promote the development of battery technology and improve electric vehicles (EV) by innovating solid-state batteries. performance. IonicMaterials is a materials technology company that develops advanced materials for high energy density batteries, making high energy density batteries safer and more affordable than existing batteries. It uses patented solid polymer materials, so that solid-state batteries have inherent safety, economy, high energy density and can be used at room temperature. And it has been proven that its polymer electrolyte is compatible with chemicals. In theory, this type of chemicals has a higher performance limit than the active materials used in the current state-of-the-art batteries. The key characteristics of the polymer include: 1. Up to 1.3mS/cm at room temperature; 2. The lithium ion migration number is 0.7; 3. Can withstand high voltage (5 volts); 4. Can adapt to the high load of the battery cathode; 5. High elastic modulus; 6. Stable to lithium; 7. Can conduct a variety of ions. IonicMaterials is a platform technology that can use various electrode chemistries including lithium metal anodes, sulfur cathodes, etc., so that batteries can have higher energy density and higher performance. It will serve as a supplier of advanced battery materials. The polymer is sold to the battery industry. Generally speaking, the expected benefits that solid-state batteries can produce include: 1. Inherent safety: eliminate the safety problems of liquid electrolytes; 2. Higher performance: achieve higher energy battery anodes and cathodes; 3. Lower cost: through adoption Cheaper chemicals and cheaper manufacturing processes reduce battery costs.
