The term "lithium battery" refers to a family of different lithium-metal chemistries, comprising many types of cathodes and electrolytes but all with metallic lithium as the anode. The battery requires from 0.15 to 0.3 kg (5 to 10 oz) of lithium per kWh.
Rechargeable lithium metal batteries are secondary lithium metal batteries.They have metallic lithium as a negative electrode.The high specific capacity of lithium metal (3,860 mAh g −1), very low redox potential (−3.040 V versus standard hydrogen electrode) and low density (0.59 g cm −3) make it the ideal negative material for high energy density battery technologies.

Press reports have stated that LLZO is believed to be the electrolyte used by QuantumScape for their solid-state lithium metal battery. [10] Japanese company Niterra is working on next-generation Lithium ion battery with LLZO as electrolyte. [11] LLZO has also been used as an electrolyte material in next-generation lithium-sulfur batteries. [12]
A solid-state electrolyte (SSE) is a solid ionic conductor and electron-insulating material and it is the characteristic component of the solid-state battery. It is useful for applications in electrical energy storage (EES) in substitution of the liquid electrolytes found in particular in lithium-ion battery.
Anode-free lithium ion batteries have been demonstrated using a variety of cathode materials, such as LiFePO 4, LiCoO 2, and LiNi 1/3 Mn 1/3 Co 1/3 (NMC 111).. These intercalation-type cathodes typically offer limited Li content (14.3 at.% for LiFePO4, 25 at.% for LiCoO2 and LiNixCoyMn1-x-yO2), although they remain the primary research targets. [2]
In September 2014, a study described an arrangement using a molten alloy of lead and antimony for the positive electrode, liquid lithium for the negative electrode; and a molten mixture of lithium salts as the electrolyte. A recent innovation is the PbBi alloy which enables lower melting point lithium-based battery.
Superconcentrated electrolytes demonstrate the following advantages: [3] (1) Many show a good oxidative stability. [1] In particular, some can suppress oxidative corrosion of an Al current collector without a source of fluoride ion (such as hexafluorophosphate) and enable the use of 5 V lithium-ion battery cathode materials.
An experimental lithium metal battery with a LiNi 0.88 Co 0.09 Mn 0.03 O 2 /NCM88 cathode material with a dual-anion ionic liquid electrolyte (ILE) 0.8Pyr 14 FSI 0.2 LiTFSI was demonstrated in 2021. This electrolyte enables initial specific capacity of 214 mAh g−1 and 88% capacity retention over 1,000 cycles with an average Coulombic ...
