New multifunctional polymer binder achieves theoretical capacity of LiFePO4 Li-ion batteries without additives

Green Car Congress

Researchers led by a team from Griffith University in Australia have developed a multifunctional polymer binder that not only maintains the outstanding binding capabilities of sodium alginate but also enhances the mechanical integrity and lithium-ion diffusion coefficient in a LiFePO 4 (LFP) electrode during the operation of the batteries.

U-M leads new DOE-funded research center for ceramic ion conductors; MUSIC

Green Car Congress

The University of Michigan (U-M) and eight partner institutions will explore the use of ceramic ion conductors as replacements for the traditional liquid or polymer electrolytes in common lithium-ion batteries for electric vehicles and in flow cells for storing renewable energy in the grid.

PNNL team develops sodium-manganese oxide electrodes for sodium-ion rechargeable batteries

Green Car Congress

Sodium is seen by some as a promising alternative, but the sodium-sulfur batteries currently in use run at temperatures above 300 °C, making them less energy efficient and safe than batteries that run at ambient temperatures. Sodium-ion batteries have been discussed in the literature. for some time. —Cao et al.

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! The mining industry cannot keep up with the demand, so the alternative is to manufacture batteries based on sodium chemistry. The big issue with sodium-ion batteries is that they can store only about two-thirds of the energy of Li-ion batteries of equivalent size.

New solid-electrolyte interphase may boost prospects for rechargeable Li-metal batteries

Green Car Congress

In a paper in Nature Materials , the Penn State team reports a molecular-level SEI design using a reactive polymer composite, which effectively suppresses electrolyte consumption in the formation and maintenance of the SEI. In this project, we used a polymer composite to create a much better SEI. V Li|LiNi 0.5 —Thomas E.

Polymer microcapsules with liquid carbonate cores and silicone shells offer a new approach to carbon capture

Green Car Congress

The team, led by scientists from Harvard University and Lawrence Livermore National Laboratory, employed a microfluidic assembly technique to produce microcapsules that contain liquid sorbents encased in highly permeable polymer shells. The polymer microcapsules are then heated to release absorbed CO 2 for subsequent collection.
