The compaction equipment is simple in structure, reasonable in design and convenient to use; the saggar is arranged on the bottom plate and can move freely; the negative electrode material of the battery is poured into the saggar and the driving motor is switched on to move a compaction plate up and down, so that the effect of compacting the negative electrode material of the battery is realized; the device can be used for repeatedly compacting the material; the compaction effect is high and the compaction efficiency is high.

Description

technical field [0001] The invention relates to battery production equipment, in particular to a compacting equipment 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 transfer, surface and interface ...

Problems solved by technology

The 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 China'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 China'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" that restricts the development of China's battery industry; currently, when producing lithium batteries, Sintering the battery material is an essential step. However, the battery material needs to be compacted before sintering. The existing equipment is not compacted completely, and the working speed is slow. Therefore, it is necessary to design a compacting device with high working efficiency. equipment to meet the needs of existing production
