Since its inception in the early 1990s, lithium-ion rechargeable battery technology has attracted widespread attention in the automotive manufacturing industry due to its excellent charging characteristics and high-density energy storage, such as compared to traditional nickel hydrogen batteries, and has become one of the key technologies driving the development of the electric vehicle (EVs) industry. At present, the significant challenges in the development and application of lithium-ion rechargeable battery technology come from: occasional short circuits that may occur, although the probability is small, may cause fires or injury accidents, such as millions of laptop or mobile phone lithium battery recalls every year, and even lead to emergency landings of Boeing 787 aircraft; Lithium battery materials and production manufacturing costs are relatively expensive.

The 7th EU R&D Framework Plan provides funding of 5.6 million euros, with a total R&D investment of 8.6 million euros. The European GREENLION R&D team is composed of 7 EU member states and associated countries Spain (overall coordination), Germany, France, Italy, Austria, Ireland, and Switzerland, as well as important automotive manufacturing companies and the scientific and technological community. Since November 2011, we have been committed to the development and application of new generation lithium-ion rechargeable battery technology for electric vehicles, with the goal of being safer, more efficient, cheaper, and greener.

The new generation of lithium battery technology in the European Union is mainly focused on the development and application of anode materials (currently graphene lithium-ion composite materials), cathode materials (currently lithium cobalt oxide materials), dielectric materials for isolating the two poles (currently lithium salt and organic solvent composite materials), as well as optimized combination technologies and production manufacturing processes. Important R&D and innovation activities include:

1) Minimize the use of chemical methods as much as possible and develop more environmentally friendly battery materials;

2) Reduce the production cost of electrode materials, such as using water-based slurry for innovative production processes in electrode manufacturing;

3) Improve the efficiency and reduce costs of battery modules and assembly production lines, such as using laser cutting and high-temperature pre-treatment technology; 4) Increase production and reduce costs, such as developing automated production and assembly lines for battery modules;

5) Develop battery modules that are easy to assemble, disassemble, and recycle, such as more compact and lightweight battery module designs;

6) Design safer and more reliable battery modules and research and development of new composite materials;

7) Reduce waste recycling and reuse, such as using new materials and battery modules that meet the recycling design as much as possible, to ensure the safe recycling of active and inactive materials in batteries.
