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. 0c02742.

Researchers show that inherent lithium ions in bioderived borate polymer enhance extreme fast charging capability in graphite anodes

Green Car Congress

In order to enable fast-charging ability in batteries, researchers have attempted to enhance the mass transfer of electrolytes and charge transfer in electrodes, with extensive research carried out on the former compared to the latter. It is an undesired process leading to reduced battery life and limiting fast charge capability.

Remembering Lithium-Ion Battery Pioneer John Goodenough

Cars That Think

Goodenough , one of the inventors of the lithium-ion battery, died on 25 June at age 100. He probably is best known for developing the lithium cobalt oxide cathode in 1980—which became the foundation for Sony’s first commercial lithium-ion battery in 1991. His first was lithium cobalt oxide.
