Study shows paper-folding concepts can compact a Li-ion battery and increase its areal energy density

Green Car Congress

Researchers at Arizona State University have shown that paper-folding concepts can be applied to Li-ion batteries in order to realize a device with higher areal energy densities. Recently, there has been much interest in the development of electronic and energy storage devices using paper and textile components.

New lithium polysulfide flow battery for large-scale energy storage

Green Car Congress

Researchers from the US Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University have designed a new lithium/polysulfide (Li/PS) semi-liquid (flow) battery for large-scale energy storage, with lithium polysulfide (Li 2 S 8 ) in ether solvent as a catholyte and metallic lithium as an anode.

Ningbo researchers propose mixed-ion Li/Na batteries

Green Car Congress

Schematics of Li + /Na + mixed-ion battery. During charging (or discharging), the storage (or release) of Li + takes place at anode, and the release (or storage) of Na + occurs at cathode. However, a number of issues remain before SIBs could become commercially competitive with Li-ion batteries (LIBs).

Ford and Samsung outline R&D efforts for next-generation non-hybrid battery technology; dual-battery systems and lightweight Li-ion

Green Car Congress

For the near term, they have been working on a dual-battery combining a lithium-ion battery with a 12-volt lead-acid battery that could enable regenerative braking technology in non-hybrid vehicles for greater fuel savings. The research advances lithium-ion battery technology currently available on Ford’s electrified vehicles.
