Recent Progress on Batteries (Mainly Li and Na)

Presenter: Dr. Zhang and Dr. Yang at Celgard Inc.

Clean energy, electric vehicles (EVs), and electric energy storage (ESS) are becoming increasingly common topics of discussion worldwide, alongside technologies like cell phones and notebook PCs. At the heart of these advancements are batteries, particularly lithium-ion batteries, which play a critical and essential role. In this talk, we will begin with an overview of the fundamentals of lithium-ion batteries, followed by a discussion of current trends in battery systems. We will then discuss the key components, i.e. cathode, anode, and electrolyte, before moving on to separators, which will be presented by Wenbin Yin. Next, we will address liquid battery safety mechanisms and conclude with a discussion on solid-state electrolyte batteries and their associated safety considerations.
