UK report sees step-change improvements in performance of EV batteries as “highly unlikely” through 2020

Green Car Congress

The Committee on Climate Change commissioned energy consultancy Element Energy , Li-ion manufacturer Axeon, and Prof. Peter Bruce of EastChem to investigate the future trajectory of batteries cost and performance. It results in a higher cost per kWh for a PHEV compared to pure battery electric vehicle.

Dow Energy Materials showcases current Li-ion cathode, anode and electrolyte systems at EVS26; layered-layered NMC cathode and Si anode materials under development

Green Car Congress

DEM is not a direct licensee of the Argonne National Laboratory layered-layered materials, noted Klanecky, but can work with cell manufacturers who are. Much further out (Horizon 3) are efforts on Lithium-air batteries and other potential chemistries. One-third of the cost of an electric vehicle is the battery itself.

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. However, key drawbacks to the Li-air system are its relatively low practical energy density, low cycle life and the complexity of the system, 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.

What’s Happening in EV Battery Technology

Driivz

From how much they cost and weigh to the amount of power they store and how long they take to charge, electric vehicle (EV) batteries have a significant impact on EVs themselves, the EV industry as a whole, and ultimately EV buyers.

EV Everywhere Blueprint outlines DOE technical and development goals for EVs for 2022

Green Car Congress

Reducing the cost of electric drive systems from $30/kW to $8/kW. When these goals are met, the levelized cost of an all-electric vehicle with a 280-mile range will be comparable to that of an ICE vehicle of similar size. Designs using WBGs will increase as manufacturing processes enable improved device yield and performance.

Battery Advances Over the Next Ten Years

My Electric Car

For example the volumetric energy density of lithium-ion batteries has increased eightfold since 2008, from around 55 watt-hours/litre to 450 watt-hours/litre in 2020. At the same time the cost of lithium-ion battery packs declined 87% between 2008 and 2021. million kilometers.
