The LIB-VTRaman-S apparatus is an in-situ Raman and optical cell for lithium ion battery under low and high temperature environment. This in-situ apparatus includes a vacuum chamber that adjusts the temperature, a temperature controller (program control), and an in-line in situ Raman lithium ion battery. The temperature adjustment range is: -30-100 ° C, the temperature control accuracy is: ± 0.5 ° C. It is possible to realize the structural detection function of the lithium ion battery in the charge and discharge process, which is an indispensable hand of the study of temperature parameters in a lithium ion battery.
