Coating gasket, battery pole piece coating device and preparation process of coating gasket
The invention discloses a coating gasket, a battery pole piece coating device and a preparation process of the coating gasket, the coating gasket is applied to a slit extrusion coating die head of a battery pole piece, at least one coating opening and at least one positioning hole are formed in the coating gasket, and the coating gasket is made of a corrosion-resistant material; the coating gasket is a ceramic gasket, and the ceramic gasket is made of full ceramic. The gasket made of the full-ceramic material is used for replacing an existing stainless steel gasket, the ceramic gasket has the acid-resisting and alkali-resisting characteristics, it is effectively guaranteed that slurry does not generate electrochemical reaction with the gasket body, corrosion of the slurry to the gasket is avoided, the service life of the gasket body is prolonged, and the maintenance cost of the gasket body is reduced.
本发明公开了一种涂布垫片、电池极片涂布装置及涂布垫片的制备工艺，所述涂布垫片应用于电池极片的狭缝挤压涂布模头，所述涂布垫片上开设有至少一个涂布开口以及至少一个定位孔，所述涂布垫片采用耐腐蚀材质制备；所述涂布垫片为陶瓷垫片，所述陶瓷垫片的材质为全陶瓷。本发明利用全陶瓷材质的垫片替换目前的不锈钢垫片，利用陶瓷垫片本身具备的耐酸、耐碱特性，有效地保证了浆料不与垫片本体发生电化学反应，避免了浆料对垫片的腐蚀，延长了垫片本体的使用寿命，降低了对垫片本体的维护成本。
