Researchers led by the Department of Energy’s Pacific Northwest National Laboratory (PNNL) have extended the capacity and duration of sodium-aluminum batteries. The new sodium-based molten salt battery uses two distinct reactions. The team previously reported a neutral molten salt reaction.

High-energy nickel (Ni)–rich cathode will play a key role in advanced lithium (Li)–ion batteries, but it suffers from moisture sensitivity, side reactions, and gas generation. The gliding occurs as the battery charges and discharges—lithium ions depart and return to cathode, straining the crystal ever so slightly each time.

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.
