Latest Studies and Developments in Lithium Ion Battery Technology Presented at American Chemical Society Meet


Lithium Ion batteries are used in most, if not all, electronic devices. Li-ion batteries can be made up of a single battery unit or made up of several units called cells.

Lithium ion batteries are the most popular type of batteries for electronics and even in electric cars because of its long battery life and performance. This is due to to their energy density slow loss of charge when not in use.

The American Chemical Society as part of the 245th National Meeting & Exposition of the American Chemical Society had several presentations on the study and resulting developments in lithium ion battery technology. Various scientific and educational organizations presented their studies during the event.

Abstracts of these studies are enumerated below and in separate articles (see related links).
