Lithium–sulfur battery

A cell pairing a lithium-metal negative electrode with a sulfur positive electrode, which is cheap, light and converts rather than intercalates. Theoretical specific energy is very high; dissolving polysulfides and short cycle life are the obstacles.

Long-duration energy storage

Storage that discharges for eight hours or more, filling gaps that lithium-ion’s one-to-four-hour systems leave. Flow, iron–air and thermal technologies compete for it by making energy capacity cheap even when power is not.

Sodium–nickel chloride battery

A high-temperature cell, run at about 270–350 °C, with molten sodium as negative, nickel and nickel chloride in molten sodium tetrachloroaluminate as positive, and a β″-alumina ceramic electrolyte between them, giving 2.58 V. Failed cells fail to low resistance, so a series string keeps working; it has served in buses, telecom backup and grid storage.

Solid electrolyte

A solid ion conductor that replaces the liquid electrolyte in an all-solid-state cell. Oxide, sulfide, halide and polymer families each need a different production route.

Stationary storage

Batteries installed in a fixed place — a container at a solar farm, a cabinet in a home — to shift energy in time or support the grid. LFP cells dominate because cost per cycle and safety matter more than mass.
