Novel lithium cell of structure

The utility model provides a novel lithium cell of structure, includes electric core, protection shield, insulated paper, nickel connection piece, and wherein the protection shield setting is in one side of electric core, and the welding of electric core both ends has the nickel connection piece, and the nickel connection piece still is connected with the protection shield, and the insulated paper parcel is outside at electric core, the nickel connection piece includes two special -shaped groove and protection shield welding pieces. The utility model provides a pair of novel lithium cell of structure compares not only simple structure with prior art, can reduce the harm because of the electric leakage of electric core produces moreover. More importantly, the utility model provides a nickel connection piece can the greatly reduced idle current in welding process, when improving utilization rate of electrical energy for calorific capacity among the welding process reduces, and then has ensured that the difficul
