China Industry Minister did not complete the comprehensive new battery recycling rules that were expected by year end 2018. Some programs like white listing, economic uncertainty for many chemistries and the pilot projects suggest further evolution will be needed for lithium ion battery recycling regulations in China. 8 Regulation continues to evolve and are not complete Source:
This starts with the selection of materials, the design of the electrode and cell structure, cell production and extends to cell integration. The study "Development perspectives for lithium-ion bat-tery cell formats" addresses precisely these aspects of battery cells, describes the status quo and presents opportunities for further development.
Specific capacity, energy density, power density, efficiency, and charge/discharge times are determined, with specific C-rates correlating to the inspection time. The test scheme must specify the working voltage window, C-rate, weight, and thickness of electrodes to accurately determine the lifespan of the LIBs. 3.4.2.
However, with the advancing establishment of the lithium-ion battery as the energy storage system of the future, this could change. For many applications, a paradigm shift is taking place: Instead of adapting the application design to the battery, the battery design is being adapted to the application.
The LIB generally consists of a positive electrode (cathode, e.g., LiCoO 2), a negative electrode (anode, e.g., graphite), an electrolyte (a mixture of lithium salts and various liquids depending on the type of LIBs), a separator, and two current collectors (Al and Cu) as shown in Figure 1.
The first lithium-ion battery (LIB), invented by Exxon Corporation in the USA, was composed of a lithium metal anode, a TiS 2 cathode, and a liquid electrolyte composed of lithium salt (LiClO 4) and organic solvents of dimethoxyethane (glyme) and tetrahydrofuran (THF), exhibiting a discharge voltage of less than 2.5 V [3, 4].
An anode-free configuration (0 N/P ratio) indicates no extra lithium is involved, which helps extend the life of LIBs. Thus, the recommended N/P ratio for full-cell configurations typically ranges between 1 and 1.2 . The N/P ratio can be adjusted by varying the density of the anode materials.
