Leaf spring and button type battery component based on leaf spring

一种弹簧片及基于弹簧片的钮扣式电池部件

Abstract

本实用新型提供一种弹簧片及基于弹簧片的钮扣式电池部件,所述基于弹簧片的钮扣式电池部件包括由上至下依次设置的顶盖、密接片、镍片、锂片、隔离膜、正极片和底盖,其中所述密接片为能够伸缩的不锈钢弹簧片。采用本实用新型所述的有明显弹性的倔强系数适中的弹簧片会大大降低钮扣式电池的内阻,提高电池的放电倍率和放电电压,以及电化学能源的高效利用率。
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.
