UMD researchers report solution to high interfacial impedance hampering developing of high-performance solid-state Li-ion batteries

Green Car Congress

Garnet-type solid-state electrolytes (SSEs) for Li-ion batteries offer a range of attractive benefits, including high ionic conductivity (approaching 1 mS cm −1 at room temperature); excellent environmental stability with processing flexibility; and a wide electrochemical stability window. With the garnet composition Li 7 La 2.75

JCESR team identifies new mechanism hampering Mg-ion batteries; unforeseen reactivity

Green Car Congress

Rechargeable magnesium batteries are of great interest as potential “beyond Li-ion” systems for extended electric vehicle range. Because magnesium is divalent, it can displace double the charge per ion (i.e., Mg 2+ rather than Li + ). As an element, magnesium is more abundant than lithium, and more stable.

Kia unveils Soul EV at Chicago Auto Show

Green Car Congress

The Soul EV is equipped with a 27kWh, air-cooled, 200 Wh/kg Li-ion polymer battery pack located beneath the floor. The 360V 96-cell lithium-ion polymer battery has been engineered for high capacity, thermal stability and safety. The Soul EV also features Kia’s first use of Organic Light Emitting Diode (OLED) technology.
