Secondary battery molding parts
Energy storing technology which can improve the electric power quality and maximize the energy effectiveness by storing and using the high efficiency of electric energy, and reduce the amount of greenhouse gas emission remarkably HYTC Co., Ltd. is producing the mold & special JIGs of equipment producing the Li battery*.
*What is Li battery?
'Li-ion' battery with excellent chemical electrical characteristic has higher energy density than the existing ‘Ni-Cd,’ ’Ni-M H’ batteries. 'Li-ion' battery is divided into 'Li-ion' battery and 'Li-Polymer' battery based on the type of electrolyte, and safety of 'Li-Polymer' battery is higher due to the less danger, easy free production and less heat generation.
