Lithiated phase

Web4 was successfully synthesized by annealing lithiated MnO 2 at a relative low temperature of 600 C, in which the lithiated MnO 2 was prepared by chemical lithiation of the electrolytic manganese dioxide (EMD) and LiI. The LiI/MnO 2 ratio and the annealing temperature were optimized to obtain the pure phase LiMn 2O 4. With the LiI/MnO WebAs a key link, lithium-ion batteries (LIBs) have emerged as a high possibility for electric reservoir roles in future grid systems., However, it is a huge challenge reducing the battery workability due to the low temperature in cold regions such as Canada, Northern Europe, and Northern China.
