Abstract:

In recent years, various governments have proposed staged goals for the development of lithium batteries with high energy densities. The main challenge is to identify a balanced solution to satisfy energy density and other characteristics such as safety, cycle life, and rate capability. This paper analyzes the main problems and possible solutions considering the available cathode, anode, electrolyte, and separator materials. A forward cell design is discussed.

Key words: high-energy densities, lithium batteries, balanced solution, materials, battery design
