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.

Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

Researchers at the University of Texas, including Dr. John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. The present sodium-sulfur battery operates above 300 °C. Example of a lithium-water rechargeable battery.

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.

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.

Testing shows Talga graphene silicon boosts capacity of Li-ion battery anode; Safevolt project

Green Car Congress

The results are the first under Talga’s UK Government funded “Safevolt” project—a Talga-led program run in conjunction with consortia partners, Johnson Matthey, the University of Cambridge and manufacturing research group, TWI.

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.
