| Use | As an organic solvent for lithium-ion battery electrolyte, it can also be used as an additive for lithium-ion battery electrolyte. The lithium-ion battery electrolyte will show excellent storage stability after adding DTO, which can improve the low-temperature performance of the electrolyte and prevent PC molecules from being embedded in the graphite electrode. Can also be used for organic synthesis, drug intermediates. |
