Abstract
The present invention discloses a lithium ion battery, including a battery shell, a battery top cap mounted on the battery shell, and a relief valve provided on the battery shell and/or the battery top cap; the lithium ion battery further includes a safety protection device that is provided on the battery shell and/or the battery top cap and that fixedly fits with the relief valve; where the safety protection device includes a baffle plate opposite to the relief valve, a side wall and a gas flow channel structure; the side wall extends, from the baffle plate, toward the battery shell or the battery top cap, and is connected with the battery shell or the battery top cap; and the gas flow channel structure is formed on the side wall. By forming the gas flow channel structure on the side wall, the baffle plate and the gas flow channel structure form a relatively separate design, so that the baffle plate may be used for effectively baffling solid spark particles, and meanwhile the lateral gas flow channel structure may be used for effectively discharging gases, thereby improving the safety performance of the lithium ion battery.
