Product Description

MLaboratory Integrated Electrode Analyzer For Lithium Battery Electrode Testing

 

 

Introduction
Background: Currently, each test item of electrode, i.e., gram weight, weight loss rate and electrode resistance et.al., are independent. Moreover, gram weight and weight loss rate need to be punched with a punching machine before the measurements.
Problem points: Slow testing efficiency, high labor consumption, low space utilization, data from
all tests need to be integrated and analyzed in the later stage, and individual items need to be individually checked and then uploaded to MES.
 

Test items	Objective	Test method
Gram weight	The weight after coating can reflect the coating uniformity, judge whether the edge thinning is within the specified range, and can effectively avoid lithium precipitation after the cell is formed	Tablet punching machine+electronic scale; m=M1-M2 (m=coating weight of fixed area, M1=coating+substrate weight, M2=substrate weight)
Weight loss rate	The weight loss rate can reflect whether the coating oven parameters are within the range	Moisture meter; X=(M1-M2)/M1 * 100%(X=sol id content, M1=weight of sample before drying, M2=weight of sample after drying)
Electrode resistance	The electrode resistance can better evaluate the performance of the electronic conductive network or the uniformity of the electrode microstructure during the electrode manufacturing process, and help to research and improve the electrode formula and the control parameters of the mixing, coating and rolling process	electrode resistance meter BER series
Peeling force	The peeling strength between the coating and the collector will affect the cycle performance and internal resistance of the lithium-ion battery	Tensile testing machine
