Abstract

A powder sintering device is disclosed. The powder sintering device includes a furnace body, a first heating device, and a vibration device. The furnace body includes a bottom wall and a side wall cooperatively defining a reaction chamber. The first heating device is located outside the furnace body, and configured to heat the furnace body. The vibration device is located outside the furnace body, and configured to vibrate the furnace body.

Description

technical field [0001] The invention relates to a powder sintering device, in particular to a powder sintering device which realizes dynamic sintering through vibration assistance. Background technique [0002] Energy issues have always been a major issue in the development of human society and science and technology. As a green secondary battery with high energy density, lithium-ion batteries have been widely used in consumer electronics products such as notebook computers, mobile phones, and cameras. Lithium-ion battery positive active material or negative active material is an important part of lithium-ion battery. At present, powder sintering is a common method for preparing positive or negative active materials for lithium-ion batteries. [0003] However, most of the existing powder sintering devices for preparing lithium-ion battery positive active materials or negative active materials adopt static sintering. Uneven, and then there are problems such as uneven sinte...
