Lux: Li-ion dominating grid storage market with 90% of 2014 proposals

Green Car Congress

Lithium-ion (Li-ion) batteries have become the dominant new technology in grid storage, capturing a 90% share of systems proposed last year, according to analysts at Lux Research. Li-ion accounted for 419 MW and 1,555 MWh of proposed storage systems in 2014. LFP, NMC are the leading Li-ion cathodes.

Researchers demonstrate high-capacity Mn-rich Li-ion cathodes; a design pathway away from cobalt and nickel

Green Car Congress

Researchers led by a team at UC Berkeley have demonstrated high-capacity manganese-rich cathodes for advanced lithium-ion batteries. Low cost and low toxicity make the Mn 2+ /Mn 4+ couple particularly desirable for designing high-performance Li-ion batteries that are also inexpensive and eco-friendly. … —Lee et al.

Smart nail for Li-ion penetration tests

Green Car Congress

Jeff Dahn and colleagues at Dalhousie University have developed a “smart nail” for penetration testing on Li-ion batteries. Nail penetration is one of the common safety tests used to simulate some aspects of an internal short circuit event in a Li-ion cell. The project is detailed in the Journal of Power Sources.

IDTechEx sees improving supercapacitors gaining market share against Li-ion batteries

Green Car Congress

A new report by market research company IDTechEx—“Electrochemical Double Layer Capacitors: Supercapacitors 2014-2024”—finds that supercapacitors are improving faster than lithium-ion batteries in most respects. Supercapacitors need not match lithium-ion battery energy density to replace much of that battery market.
