Composite current collector is a multilayer structure material composed of alternating conductive layers (such as aluminum foil, copper foil) and insulating layers (such as PET, PI), which has both conductivity and mechanical support functions. In the future, composite current collector is expected to become the mainstream current collector material and promote the development of the lithium battery industry
·New multi-probe measurement principle
·Due to the insulating layer in the middle of the composite current collector, the traditional two-probe resistor cannot accurately measure its resistance value.
·The instrument adopts a new probe design and is equipped with a fully closed-loop intelligent servo control system to realize the overall resistance of the composite electrode and its double-sided resistance consistency and other characteristic detection.
Note: Ra is the overall resistance of the active coating, Rc is the current collector resistance, m is the pole piece weight, S is the sample area, l is the sample thickness |
1. Composite current collector vs. aluminum foil current collector ·The resistance of the composite current collector is at the same level as that of the aluminum foil current collector; ·The composite current collector can provide the same level of electrical performance as the traditional aluminum foil current collector.
| 2. Application of resistance difference analysis of composite electrode under different pressures ·As the applied pressure increases, the electrode resistance decreases accordingly; ·Evaluate the effect of pressure on the conductivity of the composite electrode, provide a reasonable pressure range, and help optimize the production process.
