PNNL team develops electrolyte for high-voltage sodium-ion battery with extended longevity

Green Car Congress

Cheap and abundant, sodium is a promising candidate for new battery technology. However, the limited performance of sodium-ion batteries has hindered large-scale application. Sodium-ion batteries (NIBs) have attracted worldwide attention for next-generation energy storage systems. —Jin et al. 2 in mole or 1.6:8.4

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.

Researchers use in situ NMR spectroscopy to provide insight into silicon expansion in Li-ion batteries

Green Car Congress

A major barrier to the use of high energy capacity silicon in a lithium-ion battery is the volumetric expansion of silicon under lithiation and delithiation, which results in electrode degradation and capacity fade. Silicon (shown in grey) is capable of holding 10 times as many lithium ions (shown in pink) as currently-used anodes.

Hollow carbon nanowires show high capacity and cycle life as anodes for sodium-ion batteries; insight into Na-ion insertion-extraction mechanism

Green Car Congress

Researchers at the Pacific Northwest National Laboratory have developed hollow carbon nanowires (HCNWs) for use as anode material for Na-ion batteries. The researchers attributed the good sodium-ion insertion properties to the short diffusion distance in the HCNWs and the large interlayer distance (0.37 Credit: ACS, Cao et al.

WSU, PNNL researchers develop viable sodium battery

Green Car Congress

Although O3-layered metal oxides are promising cathode materials for high-energy Na-ion batteries, they suffer from fast capacity fade. However, the nickel rich O3-NaTMOs suffer from irreversible phase transition at high voltage and limited cycle life, similar to their Li analogues, if not even worse.

ASU team develops new solution for mitigating Li dendrite growth by tackling plating-induced residual stress

Green Car Congress

Almost all metals used as battery anodes tend to develop dendrites For example, these findings have implications for zinc, sodium and aluminum batteries as well. Here, we aim to provide answers to the above fundamental questions by designing experiments for plating Li on a thin copper (Cu) current collector supported by soft substrates.
