6. Product Usage Guide (Lithium ion battery application)
1) This product can be used directly, but it needs to be stirred thoroughly before use
l Recommended stirring speed：＞8 m/s
l Recommended stirring time：8-25 minutes
2) HSV 9000 or PVDF of similar molecular weight is recommended. According to the formula ratio, appropriate amount of JY-GQS01 powder was added to PVDF powder or PVDF solution pre-dissolved in NMP, and stirred. Finally, appropriate amount of active material was gradually and slowly added to the mixture and stirred and dispersed evenly, that is, the preparation of electrode slurry was completed
l Recommended stirring speed：＞20 m/s
l Recommended stirring time：4 hours
3) It is recommended that each step of the batching process be carried out in a dry environment
l Note: In order to achieve the best performance requirements of this product:When the whole bag of powder can not be consumed at one time, in order to prevent the influence of air moisture absorption of the powder on product quality, the bag mouth must be quickly sealed after use; Moreover, if the storage time is too long, it is recommended to test the moisture content of the powder in use.
3. Storage Requirements
The shelf life of the product is 24 months from the date of production under the original sealed condition.
The storage temperature must not exceed 50°C (120°F).
