PNNL: single-crystal nickel-rich cathode holds promise for next-generation Li-ion batteries

Green Car Congress

High-energy nickel (Ni)–rich cathode will play a key role in advanced lithium (Li)–ion batteries, but it suffers from moisture sensitivity, side reactions, and gas generation. We observe reversible planar gliding and microcracking along the (003) plane in a single-crystalline Ni-rich cathode. —Bi et al.

New aqueous rechargeable lithium battery shows good safety, high reliability, high energy density and low cost; another post Li-ion alternative

Green Car Congress

Schematic illustration of the aqueous rechargeable lithium battery (ARLB) using the coated lithium metal as anode, LiMn 2 O 4 as cathode and 0.5 mol l -1 Li 2 SO 4 aqueous solution as electrolyte. Here we introduce a coating layer on lithium metal. The coated lithium metal is stable in aqueous electrolytes.

Researchers demonstrate high-capacity Mn-rich Li-ion cathodes; a design pathway away from cobalt and nickel

Green Car Congress

Researchers led by a team at UC Berkeley have demonstrated high-capacity manganese-rich cathodes for advanced lithium-ion batteries. On one end of this compositional spectrum, LiCoO 2 dominates the electronics sector, whereas Ni-rich materials are of interest for the automotive sector. —Lee et al. V, 20 mA g ?

Beijing, Argonne researchers develop new solid-state Li-ion battery; glassy nanocomposite electrolyte with ILs

Green Car Congress

In … solid-state LIBs [lithium-ion batteries], one important component that needs to be improved to make it more suitable for high performance applications is the electrolyte material. Such solid composite electrolytes also have been previously shown to reduce lithium dendrite formation and proliferation in lithium metal batteries.
