After the electrode sheet is rolled press, the energy density of the lithium battery can be increased, and the binder can firmly stick the electrode material to the collector of the electrode sheet, so as to prevent the loss of lithium battery energy because the electrode material falls off from the collector of the pole sheet during the cycle.

Battery roll press has become one of the indispensable key equipment in modern battery manufacturing industry due to its high efficiency production, high quality electrode, flexible and adjustable, energy saving and environmental protection.
