24M emerges from stealth mode with new semi-solid Li-ion cell; <$100/kWh by 2020

Green Car Congress

Together, our inventions achieve what lithium-ion has yet to do—meet the ultra-low cost targets of the grid and transportation industries. By 2020 our battery costs will be less than $100 a kilowatt-hour (kWh). For example, a lead acid battery does not perform well at 1 C C-rate. Earlier post.).

PNNL study outlines requirements for grid storage, reviews four electrochemical energy storage systems: vanadium redox flow, Na-beta, Li-ion and lead-carbon

Green Car Congress

To smooth out the intermittency of renewable energy production, low-cost electrical energy storage (EES) will become necessary. electricity) to hybrid and electrical vehicles, although the cost of implementing EES is of great concern. Carrying charges, operation and maintenances (O&M), and replacement costs are not included.

ARPA-E to award $30M to increase performance of solid ion conductors for batteries, fuel cells

Green Car Congress

Program Categories include: Lithium (Li) ion conductors that enable the cycling of Li metal without shorting; Selective and low-cost separators for batteries with liquid reactants (e.g., in a fuel cell for combined heat and power applications) as well as to store electrical energy in chemical bonds (e.g. Background.
