The nickel–lithium battery, also known as Ni–Li, is a battery using a

nickel hydroxide Nickel(II) hydroxide is the inorganic compound with the formula Ni(OH)2. It is an apple-green solid that dissolves with decomposition in ammonia and amines and is attacked by acids. It is electroactive, being converted to the Ni(III) oxy-hydroxi ...

cathode A cathode is the electrode from which a conventional current leaves a polarized electrical device. This definition can be recalled by using the mnemonic ''CCD'' for ''Cathode Current Departs''. A conventional current describes the direction i ...

lithium Lithium (from el, λίθος, lithos, lit=stone) is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the least dense metal and the least dense solid ...

anode An anode is an electrode of a polarized electrical device through which conventional current enters the device. This contrasts with a cathode, an electrode of the device through which conventional current leaves the device. A common mnemoni ...

. The two metals cannot normally be used together in a battery, as there are no electrolytes compatible with both. The

LISICON LISICON is an acronym for LIthium Super Ionic CONductor, which refers to a family of solids with the chemical formula Li2+2xZn1−xGeO4. The first example of this structure was discovered in 1977 with , providing a chemical formula of Li14Zn(G ...

design uses a layer of porous glass to separate two electrolytes in contact with each metal. The battery is predicted to hold more than twice as much energy per kilogram as

lithium-ion batteries A lithium-ion or Li-ion battery is a type of rechargeable battery which uses the reversible reduction of lithium ions to store energy. It is the predominant battery type used in portable consumer electronics and electric vehicles. It also see ...

, and to be safer. However, the battery will be complex to manufacture and durability issues have yet to be resolved. Ni-Li has a very high cell potential, but is limited in capacity by the cathode material.
