Rubberizing structure on the volume core of present lithium ion battery is to adopt three rubberizings promptly to paste to tighten adhesive tape, bottom adhesive tape and the mode that stops adhesive tape realizes substantially, tightens adhesive tape and just pastes one little and be used to prevent that insulation cushion from coming off; Stop adhesive tape and can only accomplish volume core ending part is covered, prevent to roll up core and become less severe; The bottom adhesive tape only plays the effect of protection volume core bottom.
A kind of lithium ion battery coil core rubberizing structure has been proposed in Chinese patent 200920130422.5, described volume core rubberizing structure, the bottom adhesive tape only plays the effect of protection volume core bottom, can't cover tightening adhesive tape and stopping adhesive tape.Because the volume core of lithium ion battery when going into shell, can exist collision and friction unavoidably, adhesive tape sticking insecure, be taken up back and faucal adhesion mutually easily cause weldering to leak during the battery welding, have potential safety hazard, can cause battery short circuit when serious, produce security incident.
Summary of the invention
In order to overcome the defective that existing lithium ion battery coil core adhesive tape easily is taken up, provide a kind of lithium ion battery coil core rubberizing structure.
The utility model is achieved by following proposal: a kind of lithium ion battery coil core rubberizing structure, it is by stopping adhesive tape, tightening adhesive tape and bottom adhesive tape forms, stop on the c-shaped upright side that is wrapped in battery roll core of adhesive tape, one end of tightening adhesive tape sticks on the outer surface that stops adhesive tape, the other end of tightening adhesive tape sticks on the upright side of battery roll core, and be the top that n shape is crossed on battery roll core, the two ends of bottom adhesive tape stick on two relative upright sides of battery roll core respectively and take the shape of the letter U and are crossed on the bottom of battery roll core, and the bottom margin that described bottom adhesive tape will be tightened the two ends of adhesive tape and be stopped adhesive tape covers.
All wrap up at the position that termination adhesive tape described in the utility model easily collides with the side of battery roll core, and knock against hard the side of battery roll core when preventing battery core winding into shell.
Tighten the upper end that adhesive tape is fixed on insulation spacer battery roll core described in the utility model, prevent that insulation spacer from double swerve occurring in the middle of the subsequent production process of lithium ion battery, avoid occurring fixedly not causing the welding waste product because of insulation spacer in the welding procedure; In addition, employing is tightened adhesive tape the thickness direction of battery roll core is tightened, and prevents that battery roll core is super thick.
Bottom adhesive tape described in the utility model is fixed the bottom of battery roll core, plays the effect of protection battery roll core bottom; Tighten the two ends of adhesive tape and the bottom margin of termination adhesive tape and covered, when lithium ion battery cell is gone into shell, be difficult for causing on two ends of tightening adhesive tape and the bottom margin that stops adhesive tape and turn over by the bottom adhesive tape; Described bottom adhesive tape takes the shape of the letter U and is crossed on the battery roll core, and during battery core winding into shell, turn on being difficult for causing at the two ends of bottom adhesive tape.
Use the described a kind of lithium ion battery coil core rubberizing structure of the technical program and have following advantage:
1. battery core winding into shell is easy, and adhesive tape turns on being difficult for;
2. reduce the lithium ion battery percent defective;
3. raising lithium ion battery security.
