CMU study concludes lithium market fluctuations unlikely to impact Li-ion battery prices significantly

Green Car Congress

A new study by a team from Carnegie Mellon University’s College of Engineering has found that even large increases in lithium prices are unlikely to increase significantly the cost of batteries or battery packs for end users such as vehicle manufactures or consumers—although some manufacturers may see reduced profit margins.

Stanford study quantifies energetic costs of grid-scale energy storage over time; current batteries the worst performers; the need to improve cycle life by 3-10x

Green Car Congress

A new study by Charles J. Benson from Stanford University and Stanford’s Global Climate and Energy Project (GCEP) has quantified the energetic costs of 7 different grid-scale energy storage technologies over time. The Stanford study considered a future US grid where up to 80% of the electricity comes from renewables.

A123 Systems to supply 1MW Li-ion grid storage system to Maui Electric Company; 2MW system for NSTAR demonstration

Green Car Congress

Li-ion battery maker A123 Systems will supply a Grid Battery System (GBS) to Maui Electric Company (MECO), a utility serving residents and businesses on the islands of Maui, Lanai and Molokai in Hawaii. The system, NSTAR’s first battery energy storage project, is proposed for installation at a substation in Medway, Mass.

Stanford scientists identify new Li-B-S solid electrolyte materials that boost lithium-ion battery performance

Green Car Congress

Stanford University scientists have identified a new solid-state Li-ion electrolyte predicted to exhibit simultaneously fast ionic conductivity, wide electrochemical stability, low cost, and low mass density. Their findings are published in a study in the journal ACS Applied Materials & Interfaces. sulfur (Li?B?S)

GM: Volt Pack Now “Hundreds” Less than $1,000/kWh; Headed to $250/kWh

Green Car Congress

Moreover, our battery team is already starting work on new concepts that will further decrease the cost of the Volt battery pack quite substantially in a second-generation Volt pack. Actually, as I read the conclusions of the study I had a feeling of déjà vu.

GM Electrochemists Suggest Ongoing Investment in Both Battery and Fuel Cell Research; Connecting the Science with Vehicle Engineering

Green Car Congress

This allows batteries for small low-range pure electric vehicles but excludes them for larger-vehicle long-range applications. Solely on the basis of the mass considerations above, we can conclude that battery-powered options are favored for small vehicles when short-range and long refueling times are acceptable. Li-ion storage.
