Sodium-Metal Chloride (ZEBRA) Batteries

2025

Abstract

Sodium-metal chloride batteries, also known as ZEBRA batteries, have a proven track record for backup power applications. They also show great potential for large-scale stationary electricity storage, which is currently dominated by lithium-ion batteries. While lithium-ion cells rely on critical cobalt and lithium and are prone to thermal runaway, ZEBRA batteries are based on abundant, noncritical sodium chloride, nickel, and alumina. In the absence of a flammable electrolyte, ZEBRA cells provide a safe failure mechanism. Operated at elevated temperatures (250-340°C), ZEBRA cells of large size and areal capacity are well suited for large-scale deployment. However, to be competitive with lithium-ion batteries, charge and discharge rate capability should be improved, and cell production costs should be reduced.

Molten-salt battery

Molten-salt batteries are a class of battery that uses molten salts as an electrolyte and offers both a high energy density and a high power density. Traditional non-rechargeable thermal batteries can be stored in their solid state at room temperature for long periods of time before being activated by heating. Rechargeable liquid-metal batteries are used for industrial power backup, special electric vehicles and for grid energy storage, to balance out intermittent renewable power sources such as solar panels and wind turbines.

Lithium-ion battery

A lithium-ion or Li-ion battery is a type of rechargeable battery which uses the reversible reduction of lithium ions to store energy. The negative electrode of a conventional lithium-ion cell is typically graphite, a form of carbon. This negative electrode is sometimes called the anode as it acts as an anode during discharge. The positive electrode is typically a metal oxide; the positive electrode is sometimes called the cathode as it acts as a cathode during discharge.

Lithium polymer battery

A lithium polymer battery, or more correctly lithium-ion polymer battery (abbreviated as LiPo, LIP, Li-poly, lithium-poly and others), is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte. High conductivity semisolid (gel) polymers form this electrolyte. These batteries provide higher specific energy than other lithium battery types and are used in applications where weight is a critical feature, such as mobile devices, radio-controlled aircraft and some electric vehicles.
