Application: Evaluate battery performance, lifespan, and safety.
Example: Multi channel charge and discharge testers from brands such as Arbin and Neware.
2. Electrochemical workstation
Function: Conduct cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and other tests to analyze the internal reaction mechanism of the battery.
Application: Study the performance of electrode materials, interface reactions, and battery aging mechanisms.
Example: Electrochemical workstations from brands such as Gamry and Bio Logic.
2、 Environmental simulation equipment
1. High and low temperature test chamber
Function: Simulate different temperature environments (-40 ℃ to 150 ℃) to test the performance of batteries under extreme temperatures.
Application: Evaluate the reliability of batteries in scenarios such as low-temperature start-up and high-temperature storage.
Example: Environmental testing chambers from brands such as ESPEC and binder.
2. Constant temperature and humidity chamber
Function: Control temperature and humidity (such as 25 ℃/60% RH), simulate actual usage environment.
Application: Study the influence of humidity on battery performance, such as corrosion, leakage, etc.
3、 Security testing equipment
1. Battery safety tester
Function: Conduct safety tests such as needle punching, squeezing, overcharging, and overdischarging to assess the risk of thermal runaway of the battery.
Application: Ensure that the battery meets safety standards (such as UL, IEC).
Example: Testing equipment that complies with UN 38.3 standards.
2. Thermal runaway testing system
Function: Monitor the temperature and pressure changes of the battery under thermal abuse conditions, and analyze thermal runaway behavior.
Application: Optimize battery thermal management system (BMS).
4、 Material analysis and characterization equipment
1. Scanning Electron Microscope (SEM)
Function: Observe the microstructure of electrode materials, such as particle size and morphology.
Application: Study the relationship between material properties and battery performance.
2. X-ray diffractometer (XRD)
Function: Analyze the crystal structure of electrode materials.
Application: Determine material composition and phase transition process.
3. Inductively Coupled Plasma Mass Spectrometer (ICP-MS)
Function: Detect the content of trace elements in battery materials.
Application: Quality control and impurity analysis.
5、 Battery manufacturing and assembly equipment
1. Electrode coating machine
Function: Uniformly coat the active substance onto the current collector to prepare electrode sheets.
Application: Laboratory scale battery prototype production.
2. Battery packaging machine
Function: Encapsulate electrodes, separators, and electrolytes into battery cells or modules.
Application: Packaging for soft pack batteries, cylindrical batteries, etc.
6、 Auxiliary equipment
1. Electronic balance
Function: Accurately weigh electrode materials, electrolytes, etc. (accuracy 0.01mg).
Application: Formula development and quality control.
2. Glove box
Function: Provide an inert gas (such as Ar) environment to prevent the electrolyte from reacting with moisture.
Application: Battery assembly and sensitive material handling.
3. Gas detector
Function: Monitor combustible gases (such as H ₂) or toxic gases (such as CO) in the experimental environment.
Application: Ensuring experimental safety.
The equipment selection for the battery laboratory should be comprehensively considered based on the research direction (such as material development, battery testing, safety assessment) and experimental scale (laboratory level or pilot level). The core equipment includes electrochemical testing instruments, environmental simulation devices, and safety testing systems, supplemented by material characterization and manufacturing equipment, which can fully support battery research and quality control.
