Advantages of porous materials in lithium button cell

In lithium button cell, the application of porous materials has significant advantages. These advantages not only affect the performance of the battery, but also have an important impact on the application and sustainability of the battery:
Enhance battery energy density and power density:
Porous materials can effectively increase the contact area between the electrolyte and the electrode material by increasing the pore structure of the electrode material. This increased surface area helps to increase the energy density of the battery, allowing it to store more electrical energy. It also increases the power density of the battery, allowing it to release electrical energy more quickly to meet the needs of devices for instantaneous high energy output. .
Improve battery cycle life and stability:
The porous structure can reduce the volume expansion and contraction of electrode materials during charge and discharge, which is one of the main reasons for the reduction of battery cycle life. By effectively absorbing and releasing lithium ions, porous materials can reduce the loss of electrode materials, extend the service life of the battery, and improve the stability and reliability of the battery.
Optimize the battery’s electronic conductivity and ion transport performance:
The structural design of porous materials can improve electronic conductivity and ion transmission rate, thereby reducing the internal resistance of the battery and reducing energy loss during energy conversion. This not only improves the charging and discharging efficiency of the battery, but also reduces heat generation and reduces the temperature rise problem of the battery in high-power applications.
Improve battery safety and high temperature resistance:
The special structure of the porous material helps improve the battery's heat dissipation capacity and reduce heat accumulation during high-power discharge, thereby reducing the risk of battery overheating. In addition, certain porous materials can also inhibit the thermal reaction inside the battery to a certain extent and enhance the stability and safety of the battery in high-temperature environments.
