Battery Electrode Resistance Analyzer Machine for Lithium Battery Testing

Battery Electrode Resistance Analyzer Machine for Lithium Battery Testing The importance of electrode resistance Electrode resistance (conductivity) influences the basic performance of batteries, not only on the power capability (internal resistance), but also on the reliability or safety performance. Through the measurement of electrode resistance the property of electric conductive, micro-structural uniformity of electrodes can be evaluated during die electrode many&manu&cture process in advance, thus help us to research and improve the formulation of composite electrodes as well as the control parameters of mixing, coating and calenderii^; processes. In the composite electrodes, the electric conductivity is determined by several primary factory, such as the inter&cial resistance between the coating layer and the conductive foil, the distributions of conductive agents, die intrixisic resistance of active material and the contact areas between particles. The functions of BER multi-function electrode resistance analysis method for electrode process monitoring are listed as follows: Comprehensively assessment of the slurry stability from the stirring, coating to the calendering process, which helps to recognize die anomaly aggregation of conductive agents in advance; Recognition of uneven mixing on mixture silicon—carbon cathode; Assessment of dectric conductivity offonnulas for diferent active materials; Assessment of electric conductivity of formulas for diferent conductive agents; Assessment of electric conductivity of the functional pre—coating lays of current collector; Failure analysis for the electric conductive networic failure of batteries; Analysis of contact resistance of the positive or negative electrode sur&ce after formation.  The limitations of traditional test methods Currently, there are several methods have been used to test the electrode resistance, such as four point probe method or multi point probe method and single point probe method. Though these traditional methods may have been maturely used in di&rent types of film industry areas, for the evaluation of the composite electrode films in lithium ion batteries, there are still several deficiencies that can not be ignored. The four point probe film resistance test method has been wildly used in thin films industries, which use four or even more probes array to test the film resistance form film sur&ce. Its test procedure is easy and simple, and it can reveal the anisotropic resistance components of thin film by a simple equivalent circuit model fitting. However, considering its test principle and model fitting process, this mediod can only be suitable for a uniform thin film with smooth sur&ce, and the test sample should be loaded on an insulating substrate for ideal resistance fitting. Unfortunately, the electrodes ofliduum ion batteries are composite electrode with complex compositions, rough sur&ce and loadit^ on a low resistance current collector, so their four point probe test data, are often inconsistent and difficult to analyze the result by theoretical models. Increasing die probe number and using more complicate models can improve the test reliability to a certain extent, but that need more complex structures, and again the result analysis is still difficult. The single point test method was another wildly used method in the lithium ion batteries industry, which use a fixed probe on the end of the curtent collector and a mobile probe on the surface of the electrode to directly measure the electrode resistance. This is a very simple way of electrode resistance test often carry out by a homebuilt system for difierent users, but it is still a rough empirical test method without considering the influence of press pressure, conductive path length, substrate materul and so on. As a result, the single point probe method can not provide a reliable and consistent electrode resistance data as well. Methods Four point probe test Single point probe test Electric test circuit Kelvin four-wire test technology + direct current stimulation Kelvin four-wire test technology + alternating-current Probe structure four assembled equidistant probes (< ® 1mm), which's tops are kept in the same plane during the test to get a physical contact with the sample surface One probe (usually is an alligator clip) is fixed on the current collector, and the other probe (usually is a Cu terminals) is mobile to contact on the sample surface Applicable samples Single component thin layer material with smooth surface Composite electrode with current collector Advantages and limitations √ Simple and fast measurement √ To reveal the anisotropic resistance components of thin film X Not suitable for composite electrode with current collector √ Simple and fast measurement √ Suitable for composite electrode with current collector x X A rough empirical test method without considering the influence of press pressure, conductive path length, substrate material, etc. * Developed with CATL the top power battery company and Authorized exclusively for the Patent.
