Abstract: With rapid popularization and application of lithium batteries，the static protective problem was increasingly important in electrolyte production process of lithium batteries. Hazards of static were discussed and the main points of static protection in the production organic electrolyte for Li-ion batteries were summarized according to the features of static，relevant technical standards as well as testing experiences of many years.Several anti-static measures aiming at the processes which are easy to produce static were introduced.It was also pointed out that static grounding，equipotential connection，control of material flow velocity，human body anti-static，and improvement of feeding etc.could be adopted to prevent or eliminate static in the production.These measures have certain significance for popula-rization.

Key words: lithium ion batteries, static, organic electrolyte, equipotential connection
