Its conductive mica powder is in the form of scales, and its appearance is off-white or light gray powder. The introduction of conductive components such as SnO 2 -Sb 2 o 3 As well as Sn, Sb, etc., when the fine powder is very easy, these conductive components are firmly accumulated as impurities in the short-circuit groove on the positive and negative electrodes of the single battery, which increases the difficulty of sorting and purifying the back-end battery, and greatly increases the separation and purification process. Operating costs

Embodiment Construction
[0029] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0030] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.
[0031] It should also be noted that the orientation terms such as "one end", "the other end", "front end", "rear end", "side end" and "outside" in the embodiments of the present invention are only relative concepts or The normal use state of the pr...

The invention provides a continuous safe discharging method and device for waste lithium batteries, a feeding mechanism is adopted to feed a plurality of waste lithium batteries into a conductive conveying mechanism one by one, so that the waste lithium batteries are clamped between an upper conductive conveying belt and a lower conductive conveying belt which are arranged on the conductive conveying mechanism in a closed mode at equal intervals, the upper conductive conveying belt and the lower conductive conveying belt are driven to move by a conductive graphite pressing roller and a conductive graphite carrier roller which are arranged oppositely and are connected with an adjustable resistor, a current meter and a switch which are connected in series, a discharge loop is formed, and the waste lithium batteries are driven to move by the upper conductive conveying belt and the lower conductive conveying belt to complete a discharge process. According to the invention, batch, continuous and automatic discharge treatment of the waste lithium batteries is realized, the discharge efficiency of the waste lithium batteries is greatly improved, complete and sufficient discharge of the waste lithium batteries can be ensured, and the discharge effect is good. The method is simple in process and low in cost, avoids the defect that new impurities are introduced by brine discharge in the mainstream market, and is green and environment-friendly.
Description
technical field [0001] The invention belongs to the technical field of recycling waste lithium batteries, and in particular relates to a continuous and safe discharge method and device for waste lithium batteries. Background technique [0002] With the increasing shortage of fossil resources and the urgent need for environmental protection, it has become a broad consensus to develop electric vehicles to reduce resource consumption and environmental pollution. As of June 2019, the number of new energy vehicles in China was 3.44 million, accounting for 1.37% of the total number of vehicles; among them, the number of pure electric vehicles was 2.81 million, accounting for 81.74% of the total number of new energy vehicles. According to the calculation of the average service life of power batteries for 5-8 years, China will begin to usher in a large-scale decommissioning wave of power lithium iron phosphate batteries in 2019. In 2020, the recycling volume of decommissioned power...
