3.7v 1000mah cell Manufacturers

Diaphragm 135 ℃ automatic shutdown protection, using internationally advanced Celgas2300PE-PP-PE three-layer composite membrane. When the temperature of the battery reaches 120 ℃, the membrane holes on both sides of the PE composite membrane are closed, the internal resistance of the battery increases, and the internal temperature of the battery slows down. When the temperature of the battery reaches 135 ℃, the PP membrane hole is closed, the battery is internally open, and the temperature of the battery is no longer increased, ensuring the safety and reliability of the battery.

The left side of the lithium iron phosphate battery is an anode composed of an olivine structure material, which is connected to the battery with aluminum foil. On the right is the negative electrode of the battery composed of carbon (graphite), which is connected to the negative electrode of the battery by a copper foil.

The "blade battery" adopts a new and familiar CTP (Cell to Pack) module free structure design, which eliminates the intermediate module link and directly integrates the battery cells into a battery pack. If we disassemble the battery pack of BYDIHAN, we can get a pile of single batteries with a length of 1 m, a width of 10 cm and a thickness of less than 2 cm. These single batteries are closely arranged and inserted into the battery pack like "blades", so they are named as blade batteries

The battery module can be understood as the intermediate product of the battery cell and pack formed after the lithium ion battery cells are combined in series and parallel, and the single battery monitoring and management device is installed. Among the three common lithium battery packaging forms, the single energy density of the soft package lithium battery is the most easy to achieve, but when it comes to module design, the task of considering the overall safety of the product is the most important, which can be said to transfer part of the cell activity to the module structure.
