Argonne, PNNL researchers develop new cobalt-free cathode for high-energy Li-ion cells

Green Car Congress

O 2 cathode with a predominant, partially-disordered lithiated-spinel structure was prepared by a low-temperature (LT) synthesis. In an open-access paper in the RSC journal Chemical Communications , the team reports that Li/LT-LiMn 0.5 Boyu Shi, Jihyeon Gim, Linze Li, Chongmin Wang, Anh Vu, Jason Croy, Michael M. V and ~4.6

Argonne and Hanyang University Develop New High-Energy Cathode Material With Improved Thermal Stability; Good Fit for PHEV Applications

Green Car Congress

SEM of Li[Ni 0.64 Mn 0.18 ]O 2 particle with concentration gradient of Ni, Co, and Mn contents. The results, say the researchers, suggest that the cathode material could enable production of batteries that meet the demanding performance and safety requirements of plug-in hybrid electric vehicles. From Sun et al.

Researchers Seek to Enhance Commercial Potential for Aluminum-Air Cell by Modeling Effects of Parasitic Hydrogen Evolution

Green Car Congress

The Aluminum-air battery, a metal-air battery system which uses a catalytic air cathode in combination with an electrolyte and an aluminum anode, offers a theoretical specific energy of 8.1 kWh/kg of Al—second only to the Li-air battery (13.0 Tags: Batteries. Earlier post.) O 2 + 2H 2 O + 4e - → 4OH -.

High-capacity GQD-coated VO2 nanoarray electrodes for high-performance Li- and Na-ion batteries

Green Car Congress

Researchers from Nanyang Technical University (NTU) in Singapore have shown high-capacity, high-rate, and durable lithium- and sodium-ion battery (LIB and NIB) performance using single-crystalline long-range-ordered bilayered VO 2 nanoarray electrodes. This is important in boosting the high-rate performance in both Li and Na ion storage.
