A battery electrolyte injection machine is a special equipment designed for the electrolyte filling step in battery manufacturing. It can accurately inject electrolyte into battery cells, a process that is crucial to battery production. With the surge in demand for electric vehicles and energy storage industries, the lithium battery market has expanded, which has also led to the advancement and innovation of injection technology.
Inside a lithium battery, the electrolyte is responsible for connecting the positive and negative electrodes and promoting the conduction of lithium ions, just as the blood in the human lungs helps the exchange of oxygen and carbon dioxide. Typical lithium-ion battery electrolytes are composed of inorganic lithium salts, organic carbonate solvents, and various additives. It is a carrier for lithium ion movement and charge transfer, and is indispensable for achieving high-performance indicators of batteries such as high voltage, high energy density, and excellent cycle life.
BOZHON cylindrical steel shell battery electrolyte injection machine is suitable for fully automatic injection batch production of cylindrical steel shell lithium batteries.
From the automatic loading of the battery cell to the final unloading, the entire process is highly automated and intelligent. Whether it is automatic code scanning, weighing, Hi-Pot testing, or key steps such as battery tray assembly, liquid filling cup installation, vacuum leakage detection, etc., they can be successfully completed without human intervention. This efficient and precise production method not only improves production efficiency, but also ensures the stability and consistency of product quality.
In terms of performance parameters, the production capacity of BOZHON cylindrical steel shell liquid filling machine can reach more than 100PPM, the yield rate exceeds 99.8%, and the equipment failure rate is controlled below 1.0%. Behind these data is BOZHON's deep accumulation in technology research and development and production and manufacturing. In particular, the high-pressure-isobaric liquid filling mode it adopts ensures the pressure balance inside and outside the battery through the static method of alternating vacuum and pressurization, avoids battery bulging, deformation and damage to the explosion-proof membrane, thereby improving the performance and safety of the battery.
In addition, the liquid filling system of BOZHON cylindrical steel shell liquid filling machine also performs well. The electrolyte storage system adopts a double tank design, which effectively solves the bubble problem and ensures the stability and accuracy of liquid filling. At the same time, the equipment can also automatically clean the pipeline, which is easy to operate and maintain, greatly reducing maintenance costs. The injection accuracy reaches ±0.5%, which can achieve high-precision injection of lithium batteries and ensure the performance and consistency of the battery.
In general, the BOZHON cylindrical steel shell battery electrolyte injection machine not only improves the production efficiency and quality stability of lithium batteries, but also reduces production costs and failure rates, injecting new impetus into the prosperity and development of the new energy industry.
