Lithium ion battery negative electrode material sintering and charging equipment

Abstract

The invention discloses lithium ion battery negative electrode material sintering and charging equipment, and relates to the technical field of manufacturing machinery. The lithium ion battery negative electrode material sintering and charging equipment comprises a main rod; a spring is fixedly connected to the middle position of the top of a base; a placing table is fixedly connected to the top of the spring; a cross rod A is fixedly connected to the left side of the placing table; a worm gear is fixedly connected to the left side of the cross rod A; the worm gear is in threaded connection with a worm; the bottom of the worm is rotatably connected with a fixed seat; when a material conveying pipe feeds materials into a crucible, the placing table located at the bottom of the crucible canmove downwards to drive the worm gear on the left side of the cross rod A to move downwards together, the worm in threaded connection with the worm gear starts to rotate, a bevel gear A on the worm drives a bevel gear B to rotate, a cross rod B fixedly connected with the bevel gear B starts to rotate, a threaded rod, in threaded connection with a clamping sleeve, of the right side of the cross rodB rotates and rotates into the clamping sleeve to make contact with the interior of the material conveying pipe, the material conveying pipe is clamped, and continuous discharging is stopped.

Description

technical field [0001] The invention relates to the technical field of manufacturing machinery, in particular to a sintering and charging device for negative electrode materials of lithium ion batteries. Background technique [0002] Lithium-ion batteries are currently the most popular rechargeable batteries; an ideal lithium battery has the characteristics of long life, small size, light weight, high energy density, safety, environmental compatibility, and low cost. Existing lithium-ion batteries generally cannot fully have the above advantages; the actual capacity and energy density provided by most batteries are far lower than their theoretical values; under severe operating conditions, the actual performance of the battery is worse, mainly because the battery There are problems such as low utilization rate and severe polarization of materials; therefore, research on lithium-ion batteries should mainly focus on ion, atom or molecule diffusion and transport, electron transf...

Problems solved by technology

Existing lithium-ion batteries generally cannot fully have the above advantages; the actual capacity and energy density provided by most batteries are far lower than their theoretical values; under severe operating conditions, the actual performance of the battery is worse, mainly because the battery There are problems such as low utilization rate and severe polarization of materials; therefore, research on lithium-ion batteries should mainly focus on ion, atom or molecule diffusion and transport, electron transfer, surface and interface structure optimization, regulation of electrochemical reactions and electrochemical energy At the same time, although my country's commercial lithium-ion battery industry is developing rapidly, domestic lithium-ion battery electrode materials mainly rely on imports. The localization and industrialization of raw materials are the key issues for my country's lithium-ion batteries to meet market demand; The prerequisite for solving this key problem is to independently develop positive and negative materials for lithium-ion batteries with high electrochemical performance. If the key materials do not break through, it will become a "bottleneck" restricting the development of my country's battery industry. At present, when producing lithium batteries, Sintering the battery material is an essential step, however, the battery material needs to be charged before sintering

[0003] The existing equipment does not have the ability to stop feeding in time when the loading is completed, resulting in unnecessary losses, so it is necessary to design a high-efficiency equipment that stops feeding when the loading is completed to meet the needs of existing production
