Graphite smashing device in lithium battery

Abstract

The invention discloses a graphite smashing device in a lithium battery. The smashing device comprises a smashing shell body, a first electromotor, a rotary shaft, smashing blades, a hairbrush, a sieve plate, sieve holes, a rubber column, a spring, a vibration motor, a second electromotor, a rotary shaft, a pulverizing cylinder, a gear, a storing shell body, a feeding pipe, a feeding shell body, ascrew rod, a third electromotor and a discharging shell body. The graphite smashing device in the lithium battery is simple in structure and novel in design, achieves automatic feeding of graphite, can conveniently break bigger graphite blocks, avoids that graphite particles splash during the breaking process, ensures the surrounding working environment quality, screens the broken graphite through the sieve holes in the surface of the sieve plate to conveniently break the graphite, during the use process, further smashes the collected graphite after screening, ensures uniform smashing for thegraphite, reduces the smashing time of the graphite, improves the smashing efficiency of the graphite, and stores the graphite smashed uniformly, the smashed graphite can be conveniently taken out, and the device is applicable to use and popularization.

Description

technical field [0001] The invention relates to a graphite crushing device, in particular to a graphite crushing device in a lithium battery, belonging to the technical field of lithium battery graphite crushing applications. Background technique [0002] Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries; lithium-ion batteries do not contain metallic lithium and are rechargeable; lithium-ion batteries generally use lithium alloy metal oxide as the positive electrode material and graphite as the Negative electrode materials, batteries using non-aqueous electrolytes. [0003] There are many problems in the use of some existing graphite crushing devices. For example, the crushing effect of some existing crushing devices is poor, and the crushing time is long, which greatly reduces the crushing efficiency of graphite. At the same time, some crushing The device may cause graphite to sputter to the outside, pollute the...

[0003] There are many problems in the use of some existing graphite crushing devices. For example, the crushing effect of some existing crushing devices is poor, and the crushing time is long, which greatly reduces the crushing efficiency of graphite. At the same time, some crushing The device may cause graphite to sputter to the outside, pollute the surrounding working environment, affect the health of workers, and is not convenient for users to use
