Electrolyte breakthrough suggests superior solid-state lithium-ion batteries are around the corner

Wed, 06/24/2020 - 10:21 -- paul Crompton

A team of Brown University researchers has found a way to double the toughness of a ceramic material used to make solid-state lithiu-ion batteries

The researchers in the US infused a ceramic with graphene to increase the material’s fracture toughness in a bid to make a more robust lithium-ion battery electrolyte.

ORNL‘s polymer and ceramic composite promises better solid-state electrolyte for lithium metal batteries

Wed, 05/20/2020 - 10:56 -- paul Crompton

Researchers at Oak Ridge National Laboratory (ORNL) have developed a thin film, highly conductive solid-state electrolyte made of a polymer and ceramic-based composite for lithium metal batteries. 

The electrolyte’s novel design is a three-dimensional interconnected structure that can provide mechanical robustness and high lithium ionic conductivity at room temperature.

Samsung’s 900Wh/L solid-state battery could open up EV possibilities

Fri, 03/13/2020 - 14:17 -- paul Crompton

Samsung has revealed a prototype solid-state battery that boasts an energy density up to 900Wh/L at around 50% smaller by volume than a conventional lithium-ion battery.

The prototype pouch cell would enable an EV to travel up to 800km on a single charge, and features a cycle life of more than 1,000 charges.

Solid-state battery breakthrough first stage in doubling energy density of lithium-ion cells

Fri, 11/29/2019 - 09:33 -- paul Crompton

Researchers at Australia's Deakin University have reported a way of using common industrial polymers to create solid electrolytes for solid-state lithium-ion batteries.

The scientists’ new solid polymer electrolyte system, based on a new lithium transport mechanism, was weakly bonded to the lithium-ion to replace the liquid solvents typically used as electrolytes in battery cells.
