Drexel team proposes TiO/CNF nanofiber mats to improve Lithium-Sulfur battery performance

Green Car Congress

Furthermore, the free-standing TiO/CNF-S cathodes developed with rapid sulfur melt infiltration (~5 sec) eradicate the need of inactive elements such as binders, additional current collectors (Al-foil) and additives. We have created freestanding porous titanium monoxide nanofiber mat as a cathode host material in lithium-sulfur batteries.

Faraday Institution commits a further $31M to battery research to deliver commercial impact

Green Car Congress

Although mass manufacture has made lithium-ion batteries cheaper, cost and durability remain obstacles to the widespread adoption of battery electrical vehicles. Degradation mechanisms can occur on length-scales from the nano to the macroscopic, and timescales from seconds up to years.

Ricardo develops new model-based EV battery control technology; evaluating new cell chemistries

Green Car Congress

One of the most significant impediments to an increased market share for plug-in vehicles is the high cost of rechargeable energy storage. This can represent a very significant cost element of a typical battery electric vehicle (BEV); manufacturers need to strike a balance between product affordability and available range between recharges.

Ford favoring bulk-type solid-state battery for next-gen energy storage

Green Car Congress

Ford is exploring a variety of “beyond Li-ion” solutions, including Lithium-sulfur, Lithium-air and solid-state lithium-ion batteries. Li-sulfur is also a low-cost system due to the low cost of sulfur, also offers high energy density, Anandan said.

PNNL licenses three technologies via Startup America; batteries, fuel cells and buildings

Green Car Congress

optioned a PNNL-developed method for building titanium oxide and carbon structures that greatly improve the performance of lithium-ion batteries. The new material stores twice as much electricity at high charge/discharge rates as current lithium ion batteries, and creates increased battery capacity and a longer cycle life.
