HCB developed and produced Li-MnO2 lithium pouch-style battery in 2007. It is the first lithium pouch cell supplier in China to achieve mass production, which has complete and core structural intellectual property rights for Li-MnO2 lithium pouch cell. We have obtained more than 10 lithium pouch cell patent certificates. HCB will continue to focus on the R&D of lithium pouch battery, and provide battery solutions that meet the upper electricity demand for various applications of the IoT.
Pouch casings are often used in lithium-polymer batteries with a solid electrolyte, providing a low-cost "flexible" (sometimes in unexpected ways) structure. Electrodes and solid electrolytes are usually layered or laminated-stacked and packaged in foil envelopes. Solid electrolytes allow for safer, leak-proof batteries. The foil structure allows a very thin and lightweight battery design for high-power applications, but the lack of rigidity in the housing makes the battery easy to expand as the battery temperature rises. When selecting a lithium pouch battery, the possibility of battery expansion must be taken into account to accommodate the specific cavity specified by the battery chamber. Batteries are also vulnerable to external mechanical damage to the battery pack. The lithium pouch battery design should prevent this possibility. This pouch cell construction using stacked electrodes is suitable for making grotesque batteries.
The cylindrical lithium battery consists of the anode, cathode and partition of the sheet battery, sandwiched in the middle, rolled up and then stuffed into a cylindrical jar. The battery was one of the first mass-produced batteries and is still very popular today. The unit has multiple rows, with lightning arresters located on opposite sides. They are adhesive connected with busbars by welding technology and are optionally wire bonded. In this case, no support plate is required. The cylindrical battery must be fixed in the battery module or battery pack by a solid gasket, or mounting bracket. In addition, the glue can also act as the primary fixator for the columnar cells. These fixtures add additional weight and complexity to the battery pack.
The lithium pouch battery does not have a rigid exterior available and uses a sealed flexible foil as a battery container. The electrode layer and the separator layer of the lithium pouch cell are stacked. For lithium pouch cells, the designer should allocate enough space for the possible swelling. The module with a single row battery with the arrester positioned on the same or opposite sides. Small lithium pouch batteries can be connected by adhesive welding or by a tab-to-tab or tab-to-busbar bridge without support. Furthermore, they can also be joined by a form using screws and busbars as a bridge without any support plates.
For lithium pouch batteries, the cell frame is often used as a primary fixation. In this case, the battery is inserted, with redundant sealing and flexible tension. The space between the batteries can even be used extra for the cooling system. Optionally, pouch cells may even be glued.
Not only has a wide variety of lithium pouch cells but also has many characteristics, such as high energy (the actual specific energy density of the battery up to 260Wh/kg).
No internal pressure under normal temperature, during the electrochemical reaction.
The lithium pouch cells for sale can work normally even after a long time of storage.
The lithium pouch battery can work in the temperature range of -40°C to +85°C.
Super Capacity Series Batteries has the world's largest capacity of the same size lithium pouch battery, and its safety performance reaches T6 level.
