DOE estimates EV battery pack costs in 2022 nearly 90% lower than in 2008

Green Car Congress

The Department of Energy’s (DOE’s) Vehicle Technologies Office estimates the cost of an electric vehicle lithium-ion battery pack declined 89% between 2008 and 2022 (using 2022 constant dollars). The 2022 estimate is $153/kWh on a usable-energy basis for production at scale of at least 100,000 units per year.

ICL model predicts lithium-ion batteries most competitive for storage applications by 2030

Green Car Congress

The model predicts lithium-ion batteries to be the cheapest technology in the coming decades. We have found that lithium-ion batteries are following in the footsteps of crystalline silicon solar panels. An open-access paper on their work is published in the journal Joule.

Study sees gradual, focused replacement of lead-acid SLI batteries by Li-ion batteries over next couple of years

Green Car Congress

A study by a team of researchers from Germany and South Africa forsees the gradual replacement of lead-acid SLI (starter, lighting and ignition) batteries with Li-ion batteries over the next couple of years. That will see an uptake of more hybrid-, plug-in hybrids and BEVs in the EU.

Industry study finds lead-acid to remain most wide-spread automotive energy storage for foreseeable future; new chemistries continue to grow

Green Car Congress

Overview of the three vehicle classes identified in the study, and their corresponding battery technologies. Their low cost and ability to start the engine at cold temperatures sets them apart in conventional and basic micro-hybrid vehicles, and as auxiliary batteries in all other automotive applications, according to the report.

Review paper: Graphene and related materials (GRMs) may play major role in energy applications

Green Car Congress

The combination of chemical functionalization and curvature control also opens new opportunities for hydrogen storage. MXene sheets are promising for energy applications, such as lithium-ion batteries, supercapacitors, and hydrogen storage. For hydrogen storage, the challenge is to achieve a gravimetric storage of 5.5%.
