Use steel nails to penetrate the battery, simulate an internal short circuit, and conduct a test to confirm if the battery is smoking, catching fire, or breaking.
To test this, it is not an option to manually drive a nail into a lithium-ion battery due to the risk of injuries from the flying nail. Therefore, a pinning test machine is necessary.
According to current understanding, the basic process of internal short circuit caused by lithium-ion batteries during the nail penetration process is as follows: Firstly, the Joule heat generated by the internal short circuit causes a rapid increase in the local temperature of the battery.
The needling test is not only a safety test for a lithium-ion battery, but also an important test to understand the basic nature of the battery. In the normal state, the positive and negative electrode sheets of a lithium-ion battery are insulated by a polymer insulating film – the diaphragm – in the organic electrolyte.
Conducted a nail penetration test on a 18650 lithium-ion battery with a capacity of 22 Ah and found that as the nail penetration rate increased, the probability of the lithium-ion battery passing the safety test increased.
The short circuit inside the battery should be artificially triggered and observed for a period of time. The nail penetration test is shown in Figure 1. If the battery does not catch fire, smoke or explode, it will pass the nail penetration test. Otherwise, it will not pass.
The Nail Penetration Test is a safety test that tests the internal short circuit tolerance of lithium-ion batteries. It is a method used for this purpose.

An earlier version of this story corrected the parties involved in arbitration in second paragraph) ©2025 Bloomberg L.P. China's Zijin Mining Group Co. aims to start producing lithium in the Democratic Republic of Congo early next year from one of the world's largest deposits of the battery metal.
London and Kinshasa, November 24, 2021 – The Democratic Republic of the Congo (DRC) can leverage its abundant cobalt resources and hydroelectric power to become a low-cost and low-emissions producer of lithium-ion battery cathode precursor materials.
Zijin also has interests in two copper mines in Congo, including a 39.6% stake in the giant Kamoa-Kakula complex, which is a partnership with Ivanhoe Mines Ltd. Congo's mines ministry didn't respond to questions sent by Bloomberg, while Cominiere – which owns 39% of Zijin's Manono project – declined to comment.
“The DRC's cost competitiveness comes from its relatively cheap access to land and low engineering, procurement and construction, or EPC, cost compared to the U.S., Poland and China,” said Kwasi Ampofo, lead author of the report and BNEF's head of metals and mining.
How to make lithium batteries?Step 1. Making Electrode The process involves mixing electrode materials with a conductive binder to create a uniform slurry with a solvent.
1. Extraction and preparation of raw materials The first step in the manufacturing of lithium batteries is extracting the raw materials. Lithium-ion batteries use raw materials to produce components critical for the battery to function properly.
The battery manufacturing process is a complex sequence of steps transforming raw materials into functional, reliable energy storage units. This guide covers the entire process, from material selection to the final product's assembly and testing.
Once assembled, battery packs are encased and connected to a battery management system. Finally, the manufacturer would test these batteries for safety and performance. Quality control includes testing the finished product, monitoring the whole manufacturing process, and inspecting the raw materials to ensure only good-quality substances are used.
It is estimated that recycling can save up to 51% of the extracted raw materials, in addition to the reduction in the use of fossil fuels and nuclear energy in both the extraction and reduction processes . One benefit of a LIB compared to a primary battery is that they can be repurposed and given a second life.
Advanced materials-processing techniques can contribute solutions to such issues. From that perspective, this work summarizes the materials-processing techniques used to fabricate the cathodes, anodes, and separators used in lithium-ion batteries.
The electrolyte facilitates ion movement between the cathode and anode, which is essential for the battery's operation. Electrolyte preparation involves: Solvent Selection: Choosing a solvent that ensures good ionic conductivity and stability. Salt Dissolution: Dissolving lithium salts (e.g., LiPF6) in the solvent creates the electrolyte solution.
Lithium batteries contain flammable electrolyte materials. When heated excessively, these materials can vaporize, leading to pressure build-up and ruptures.
Heat Generation and Temperature Behavior: Charge and Discharge Process: The charging and discharging of lithium-ion batteries involve various charge transport and chemical reactions, which lead to the generation of heat. The balance between reversible and irreversible heat components is crucial for understanding temperature behavior.
A profound understanding of the thermal behaviors exhibited by lithium-ion batteries, along with the implementation of advanced temperature control strategies for battery packs, remains a critical pursuit.
As rechargeable batteries, lithium-ion batteries serve as power sources in various application systems. Temperature, as a critical factor, significantly impacts on the performance of lithium-ion batteries and also limits the application of lithium-ion batteries. Moreover, different temperature conditions result in different adverse effects.
The results show that harsh conditions, such as high temperature, low temperature, low pressure, and fast charging under vibration, significantly accelerate battery degradation and reduce the thermal safety of lithium-ion batteries in these application scenarios and working conditions.
Inadequate thermal management of lithium-ion batteries can lead to a phenomenon known as thermal runaway. Figure 4 b offers a detailed depiction, elucidating the typical progression of thermal runaway in lithium-ion batteries. This process unfolds in distinct stages.
Thermal Management of Lithium-Ion Batteries C. Zhang et al. achieved temperature control of a lithium-ion battery (TAFEL-LAE895 100 Ah ternary) in electric cars by combining heat pipes (HP) and a thermoelectric cooler (TEC). The utilization of heat pipes, with their high thermal conductivity, increased temperature loss.
