All the reasons why lithium batteries have excessive internal resistance

source:other news release time:2022-10-22 Hits:0     Popular:Lithium-ion battery wholesale

  

  1. Uneven distribution of ingredients

  2. The welding between the positive ear and the shell is not firm

  3, the negative pole ear and pole welding is not strong

  4. The positive pole lug is not firmly welded, and there is virtual welding

  5, the negative ear welding or riveting is not firm, there is welding, welding

  6. The surface density design of the coating slurry is too large (large ion migration distance)

  7, the winding is not tight, the core relaxation (so that the distance between the positive and negative pieces increases)

  8, the binder solvent is not completely (not completely soluble in NMP, water)

  9, too much positive ingredient binder (binder is generally polymer material, strong insulation performance)

  10, too much negative batching binder (binder is generally polymer material, strong insulation performance)

  11, lithium ion battery compaction density is too large, roll compaction is too solid. (Roll over death, active material structure is destroyed)

  12. Too little conductive agent for the positive ingredient (the conductivity between materials is not good, because the conductivity of lithium cobalt itself is very poor)
