A conductive agent is a key auxiliary material of a lithium battery, which is coated on positive electrode material and negative electrode material. A certain amount of conductive agent will be added during the production of the pole piece to increase the conductivity of electrons and lithium ions.
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.
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.
Li-ion transport through the interface between the electrolyte and the electrodes affects the overall conductivity of solid-state batteries and the chemical stability of the interface. “Point-to-point” ion diffusion may occur at the interface due to poor interfacial contact.
(2) The additional amount is small. According to the calculation of Gaogong Lithium, the traditional carbon black conductive agent is added in an amount of about 3% by weight of the positive electrode material, while the addition amount of new conductive agents such as carbon nanotubes and graphene is reduced to 0.8%-1.5%, which is low.
Constructing stable Si electrodes with high areal capacity is crucial for improving the total energy density of lithium ion batteries (LIBs). However, it remains challenging because the poor intrinsic conductivity and serious pulverization of Si usually lead to the active material falling-off from the conductive network.
