The advent of battery-based societies and the global environment in the 21st century

In paving the way for a new electricity-based civilization in the 21st century, we hope to find the key to solving the trilemma of securing energy and resources, maintaining economic growth, and preserving the environment. In these circumstances, secondary batteries are expected to be used on a large scale in a new field—for energy purposes and to positively affect preservation of the global environment, resulting in the advent of a new battery-based society in the 21st century. It is important to develop secondary batteries not only with high specific energy for convenience, but also with large capacity, high energy efficiency and long life cycle for effective use of primary energy resources including natural energy. Lithium secondary batteries are a promising option.
