PNNL: single-crystal nickel-rich cathode holds promise for next-generation Li-ion batteries

Green Car Congress

High-energy nickel (Ni)–rich cathode will play a key role in advanced lithium (Li)–ion batteries, but it suffers from moisture sensitivity, side reactions, and gas generation. Researchers are working on ways to store more energy in the cathode materials by increasing nickel content. —Bi et al.

KERI researchers develop high-capacity Li-metal battery with improved rate performance and stability

Green Car Congress

A research team at Korea Electrotechnology Research Institute (KERI) has developed a high-capacity Li-metal battery with improved rate performance and stability using a one-dimensional Li-confinable porous hollow carbon host. However, these hosts suffer from unwanted Li growth on their surface (i.e., Kang et al.

Prieto introduces latest prototype of 3D Li-ion battery with 3-minute charging

Green Car Congress

All three attributes of Prieto’s lithium-ion battery were tested and validated by a third-party accredited battery testing lab, Prieto said. To charge, lithium ions must flow from one surface to the other, resulting in serious limitations. Thicker 2D batteries store more energy, but the long ion pathways result in slow charging.

LG Chem invests in Enevate; silicon-dominant Li-ion battery technology

Green Car Congress

Introduced in November 2017, Enevate’s HD-Energy Technology for EVs enables Lithium-ion (Li-ion) cells with up to 50% higher capacity than conventional graphite cells. The conductive, silicon-dominant composite film anode is essentially 100% active material that can store lithium and has a high electrical conductivity.

IIT, Argonne team designs Li2O-based Li-air battery with solid electrolyte; four-electron reaction for higher energy density

Green Car Congress

The team’s battery chemistry with the solid electrolyte can potentially boost the energy density by as much as four times above lithium-ion batteries, which translates into longer driving range. A lithium-air battery based on lithium oxide (Li 2 O) formation can theoretically deliver an energy density that is comparable to that of gasoline.
