In this paper, carbon nanotubes and graphene are combined with traditional conductive agent (Super-P/KS-15) to prepare a new type of composite conductive agent to study the effect of composite conductive agent on the internal resistance and performance of lithium iron phosphate batteries.
The LiNi 0.5 Co 0.2 Mn 0.5 O 2 electrode with carbon nanotubes showed 98.5% of the capacity retention after 100 cycles. A thorough comparison of three conductive additives demonstrates that carbon nanotubes are the most compatible and promising conductive additives for modern conventional manufacturing of high-power Li-ion batteries.
This ratio of conductive agent enhances the conductivity of the pole piece, allowing electrons to flow between the material particles. The conduction resistance between the particles and the current collector is reduced, thereby reducing the internal resistance of the battery.
The ratio of the latter is selected depending on battery types and conditions of use. Currently, perspective conductive additives such as carbon nanotubes [16, 17, 28], graphene [28, 29], and other electrically conductive binder [30, 31] are widely studied.
