Novel copolymer binder extends the life of lithium-ion batteries

Green Car Congress

One of the major causes for the drop in capacity over time in Li-ion batteries is the degradation of the widely used graphite anodes. interactions between the bis-imino-acenaphthenequinone groups and graphite, and also from the good adherence of the copolymer’s ligands to the copper current collector of the battery. —Prof.

Who Really Invented the Rechargeable Lithium-Ion Battery?

Cars That Think

Fifty years after the birth of the rechargeable lithium-ion battery, it’s easy to see its value. It was manufactured in small volumes by Exxon, appeared at an electric vehicle show in Chicago in 1977, and served briefly as a coin cell battery. Did Exxon invent the rechargeable lithium battery?

ORNL researchers develop new electrolyte for extreme fast charging

Green Car Congress

Researchers from Oak Ridge National Laboratory (ORNL) and colleagues have developed a novel high-performance electrolyte (HPE) consisting of lithium bis(fluorosulfonyl)imide (LiFSI), lithium hexafluorophosphate (LiPF 6 ) and carbonates to support extreme fast charging (XFC). The cell recharged 80% of its capacity in 10 minutes.
