Key Benefits of TYCORUN 3.7V Rechargeable Lithium Batteries
Store More Electricity and Improve Efficiency
TYCORUN uses high-quality battery materials to create a high-energy-density 3.7v lithium battery with an energy density of up to 200-300Wh/kg. It can store more energy per unit volume and has the advantages of small size and light weight. It is the best energy choice for portable energy and electric vehicles.
Supports Application in Harsh Environments
TYCORUN adopts advanced lithium iron phosphate battery technology and multiple safety designs, and uses high-quality diaphragm materials to prevent internal short circuits. The efficient overcharge, over-discharge, over-current, and temperature control protection mechanisms make the battery have ultra-high stability, ensuring that the battery can operate stably in extreme environments from -20℃ to 60℃.
Improve Safety and Energy Density
TYCORUN insists on innovation. The new generation of battery products – solid-state batteries use solid electrolytes and do not contain flammable liquid electrolytes, effectively avoiding the risks of leakage, fire and explosion. Using metallic lithium as the negative electrode material, the energy density can theoretically reach 400-500 Wh/kg, which is far higher than traditional lithium-ion batteries.
Reduce Cell Voltage Difference and Improve Matching
Through advanced production technology and strict manufacturing process control, TYCORUN’s 3.7v lithium ion battery has excellent consistency, small cell voltage difference, and precise matching when the cells are connected in series or in parallel to ensure battery pack performance. In addition, customized capacity, voltage, and size solutions are also provided.
