What is battery formula testing?


As we found that many companies have battery testing demand due to their new chemistry materials, for receiving the performance curve and ensure the chosen battery solution operates according to specifications.


The main purpose of rapid battery sampling service is receiving testing reports early, to ensure the feasibility of battery formulas. In the process of our communication with clients, we found that many companies will want to test the “secret battery formula”, but lack the ability to manufacture and produce batteries, so the battery manufacturer is more willing to assist with these kinds of collaboration.


The battery manufacturer can assist in battery cell design and modeling, provide few samples to test and preview the product before mass production.

How FAST of battery sampling service?


Let’s talk about the entire service process first, which is containing four stages:


1. Signing a confidentiality agreement.


2. Evaluation

Before battery prototyping, our engineers will evaluate the formula and prepare the related materials, most of the materials we have reserves, such as cathode and anode materials, electrolyte and diaphragm, except for some special and new materials, need to be transported or purchased from other places to the production location. After the material is complete and the plan is determined, the sample can be started.


3. Confirmation of initial planning (1 day or according to customer requirements).


4. Sample Production and Testing.




For production techniques, Grepow is specialize in stacking technology provides the ability to produce samples in a short amount of time, which is faster than the traditional winding method. We prepare our materials early, and we offer a pipeline production for cell prototypes:


Button Batteries: can be manufactured and tested in as early as 7 days.

Grepow uses a variety of chemical components and configurations from different countries such as:


  • China
  • Japan
  • South Korea
  • Switzerland
  • etc.


We can enhance your particular cell technology. If there are special requirements for new materials, we can assist your engineers in a joint development.


In addition, Grepow also has many high-quality materials:


Diaphragm: high gap diaphragm, ceramic diaphragm and ultrathin diaphragm;


battery diaphragm


Electrolyte: Low Temperature Electrolyte, High Temperature Electrolyte;


Electrode: Bundle CNT (Carbon Nano Tube).

Round testing for different processes


In addition to the standard capacity test, we also perform a comprehensive cycle test on the batteries to ensure a better display of test data, general testing contains:


Capacity (For testing material capacity, up to 7 days)

  • Internal resistance
  • Voltage
  • Cycle performance
  • High and low temperature discharge performance
  • Full power storage
  • Rate discharge performance
  • Safety performance
  • etc.


In all of the following tests, and in general, the test conditions must be specified so that repeatable results can be obtained, and comparisons can be made. This includes factors such as method, temperature, DOD, load and duty cycles.
