Abstract: Increasing energy density of rechargeable batteries is highly desired by many emerging applications. It is necessary to identify possible solutions for achieving both high energy density and other required performances. Based on personal knowledge and understandings, this perspective paper summarizes the main scientific and technological problems of solid lithium battries as well as reported solutions. In view of practical application, the features of four types solid lithium batteries with different solid electrolyte are compared. And a roadmap is drawn accordingly. In addition, the technological targets of the energy density of lithium batteries from USA, Japan and China government are listed. The positions of the solid lithium batteries in the roadmap are marked.

Key words: nonaqueous lithium ion batteries, metallic lithium ion batteries, semi-solid lithium batteries, all solid lithium batteries, roadmapvision and strategies
