Femtosecond laser lithium ion battery

Abstract

The invention discloses a femtosecond laser lithium ion battery. The femtosecond laser lithium ion battery comprises a positioning frame, an electromagnetic sleeve, an ultrasonic oxygen discharging device, a lithium ion storage and discharge device and a control box. The positioning frame comprises a support platform, a left adjusting bolt, a right adjusting bolt, a left sealing disc and a right sealing disc, wherein the support platform is provided with a supporting plate, and the top side wall of the supporting plate is welded with a left positioning vertical plate and a right positioning vertical plate, and one side wall of the left positioning vertical plate is provided with a left inner threaded sleeve, ad one side wall of the right positioning vertical plate is provided with a rightinner threaded sleeve. The lithium ion battery discharge device has positively charged lithium ions under the action of the applied electric field when being charged through a conductive connector, the lithium ions are moved from a lithium cobaltate cathode plate to a graphite anode plate, and perform chemical reaction with graphite, and the externally sleeved electromagnetic sleeve can instantlyincrease the electromagnetic field strength under the laser shock generated by the femtosecond laser emitter so that the movement speed of the lithium ion battery is increased to achieve quick charge.

Description

technical field [0001] The invention relates to the technical field of lithium ion batteries, in particular to a femtosecond laser lithium ion battery. Background technique [0002] Lithium-ion battery is an emerging new energy, which has the advantages of large charging capacity, long service life, and good safety. Now it is gradually replacing traditional lead batteries. However, there are still a lot of problems in lithium-ion batteries, mainly concentrated in the following Aspects: 1. The charging time of lithium batteries for large trams is long, and electric energy cannot be provided in time; 2. Lithium-ion batteries will produce chemical reactions during charging and discharging, which will be accompanied by a large amount of heat. High-heat environments will easily cause the batteries to expand. It also affects the storage capacity of the battery, and more serious self-explosion phenomenon will occur; 3. When lithium-ion batteries are recycled, methods such as discha...
