▎ 摘　　要

NOVELTY - The system has an information processing module that includes a low-temperature performance testing module and communication connection, the information processing module communication connection with a display module. A low-temperature performance test module is used for low-temperature performance experiments of graphene batteries, and the experimental result data of graphene batteries in low-temperature performance experiments are obtained. The experimental result data is sent to the information processing module. The coefficient of performance score XN is calculated for each group of graphene batteries separately, after the information processing module receives the experimental result data sent by the low temperature performance testing module. The coefficient of performance score XN is compared with the preset performance threshold. A display module is used to display the data of each experimental group and the performance coefficient score and cost score through the display. USE - Low-temperature performance test system for graphene batteries with different lignins. ADVANTAGE - The performance and cost of the graphene battery is reasonably distributed, and obtains more reasonable proportion graphene of the battery component, which is more beneficial for development of graphene battery. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of low-temperature performance test system for graphene batteries with different lignins. (Drawing includes non-English language text)
