The nickel–lithium battery (Ni–Li) is a battery using a nickel hydroxide
cathode A cathode is the electrode from which a conventional current leaves a polarized electrical device such as a lead-acid battery. This definition can be recalled by using the mnemonic ''CCD'' for ''Cathode Current Departs''. Conventional curren ...

lithium Lithium (from , , ) is a chemical element; it has chemical symbol, symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard temperature and pressure, standard conditions, it is the least dense metal and the ...
anode An anode usually is an electrode of a polarized electrical device through which conventional current enters the device. This contrasts with a cathode, which is usually an electrode of the device through which conventional current leaves the devic ...
. 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, providing a chemical formula of Li14Zn(GeO4)4. ...

lithium-ion batteries A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li+ ions into electronically conducting solids to store energy. Li-ion batteries are characterized by higher specific energy, energy ...
, 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.
