Leaf spring and button type battery component based on leaf spring



The utility model provides a leaf spring and a button type battery component based on the leaf spring. The button type battery component based on the leaf spring comprises a top cover, a joint sealing piece, a nickel piece, a lithium piece, a separation film, a positive plate and a bottom cover which are arranged sequentially from top to bottom, wherein the joint sealing piece is a retractable stainless steel leaf spring. The leaf spring having obvious elasticity and a medium stiffness coefficient can greatly reduce internal resistance of a button type battery and improves the discharge rate and the discharge voltage of the battery and the efficient utilization rate of electrochemical energy sources.
