UV Printing Process for Electrode Sheets | Insulation Printing Technology for Lithium-Ion Battery Electrode Sheets

The Climax lithium-ion battery electrode UV printing process is currently the leading high-precision insulating printing technology in the lithium-ion battery manufacturing sector. This process offers nanometre-level printing precision, enabling accurate, targeted printing on specific areas of lithium-ion battery electrodes. When combined with Climax’ proprietary UV insulating ink developed specifically for lithium-ion batteries, it comprehensively optimises traditional electrode processing workflows, effectively improves production yield, and is suitable for mass production scenarios involving various types of power batteries and energy storage batteries.

Process Principle

The complete electrode UV printing system is equipped with an intelligent control module that precisely regulates the timing of printing start and stop sequences, whilst utilising independent drive control technology for each nozzle. The equipment receives digital commands via a computer terminal to achieve high-precision coating formation on lithium-ion battery electrodes. The process offers broad adaptability, enabling the direct printing of irregular electrode shapes and integrated hollow insulation patterns, thereby meeting customised edge protection requirements for electrodes of various battery specifications.

Core Functions

1. Enhanced Battery Safety

A dense insulating protective layer is formed along the electrode edges, completely isolating the electrodes from internal battery components. This eliminates short-circuit faults, thereby strengthening lithium-ion battery safety at the process level.

2. Extended Battery Cycle Life

The cured coating effectively enhances the mechanical strength of the electrode edges, reducing issues such as electrode material shedding and damage during charge-discharge cycles. This significantly optimises the cycle performance of power and energy storage batteries, thereby extending the overall service life of the battery.

3. Enhanced Battery Thermal Stability

It substantially improves the high-temperature resistance of the electrode edges, enabling the battery to remain stable under high-temperature and high-load conditions. This further strengthens the thermal stability of lithium-ion batteries and mitigates safety risks associated with high temperatures.
