Argonne researchers find cathode material synthesis a key reason for performance degradation of sodium-ion batteries

Green Car Congress

One of the more promising candidates for batteries beyond the current standard of lithium-ion materials is the sodium-ion (Na-ion) battery. Na-ion is particularly attractive because of the greater abundance and lower cost of sodium compared with lithium. In addition, when cycled at high voltage (4.5

U Alberta team develops hybrid sodium-ion capacitor; intermediate in energy & power between ultracaps and batteries

Green Car Congress

A team led by researchers from the University of Alberta (Canada) Scientists has developed a hybrid sodium-ion capacitor (NIC) using active materials in both the anode and the cathode derived entirely from peanut shells—a green and highly economical waste globally generated at more than 6 million tons per year. 1 occurring below 0.1

RAL proposes new efficient and low-cost process to crack ammonia for hydrogen using sodium amide; transportation applications

Green Car Congress

RAL researchers are proposing a new process for the decomposition of ammonia to release hydrogen that involves the stoichiometric decomposition and formation of sodium amide from Na metal. To date, very few candidates show potential beyond that of the seminal work on titanium-doped sodium alanate. Credit: ACS, David et al.

Researchers show that layered calcium transition metal oxides can be promising cathode materials for Ca-ion batteries

Green Car Congress

However, there still remain some major hurdles to the development of Ca-based batteries, one of them being a lack of knowledge on suitable cathode materials that can efficiently store and release Ca in a reversible manner.

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

Green Car Congress

Researchers are working on ways to store more energy in the cathode materials by increasing nickel content. Nickel-rich cathode materials have real potential to store more energy. These carry advantages for storing and discharging energy faster. (Image courtesy of Jie Xiao | Pacific Northwest National Laboratory).

Antimony nanocrystals as high-capacity anode materials for both Li-ion and Na-ion batteries

Green Car Congress

V potential range. Initial studies revealed that antimony could be suitable for both rechargeable lithium- and sodium-ion batteries because it is able to store both kinds of ions. Kovalenko estimates that tt will be another decade or so before a sodium-ion battery with antimony electrodes could hit the market.
