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

Stanford team develops sodium-ion battery with performance equivalent to Li-ion, but at much lower cost

Green Car Congress

Stanford researchers have developed a sodium-ion battery (SIB) that can store the same amount of energy as a state-of-the-art lithium ion, at substantially lower cost. Thus, further research is required to find better sodium host materials. The sodium salt makes up the cathode; the anode is made up of phosphorous.

EV Guru: Sodium-Ion Batteries are Coming Sooner Than You think!

Plug In India

Video: EV Guru: Sodium-Ion Batteries are Coming Sooner Than You think! “Tesla might actually have to get into the mining & refining directly at scale, unless costs improve. The mining industry cannot keep up with the demand, so the alternative is to manufacture batteries based on sodium chemistry.

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.

Stanford study quantifies energetic costs of grid-scale energy storage over time; current batteries the worst performers; the need to improve cycle life by 3-10x

Green Car Congress

Benson from Stanford University and Stanford’s Global Climate and Energy Project (GCEP) has quantified the energetic costs of 7 different grid-scale energy storage technologies over time. To quantify the long-term energetic costs, Barnhart and Benson came up with a new mathematical formula they dubbed ESOI, or energy stored on investment.

New solid hydrogen-on-demand fuel cell from HES Energy Systems flies UAV for record 6 hours

Green Car Congress

Unlike a typical hydrogen fuel cell, the system doesn’t store its fuel as pressurized hydrogen gas, but stores it as a solid chemical material, making it easy for end-users to handle in the field. HES has been able to show that its system can store 7% of its weight as hydrogen with a fuel utilization rate of close to 90%.
