Title: Guoping Deng: Innovator in Battery Technology
Introduction
Guoping Deng is a notable inventor based in Lawrenceville, GA (US), recognized for his contributions to battery technology. He holds a total of 4 patents, showcasing his innovative approach to enhancing the safety and efficiency of rechargeable cells.
Latest Patents
One of his latest patents is a current interrupt device for rechargeable cells. This device features a safety valve, insulating spacer, and a thin metal plate that couples to an electrode assembly. The thin metal plate is electrically connected to the safety valve through a conductive polymer, which has a positive temperature coefficient characteristic. This characteristic allows the polymer to conduct current under normal conditions, while it becomes an insulator in high current situations, effectively disconnecting the cell from the exterior can when necessary. Another significant patent is related to lithium-ion battery electrode composition. This innovation involves a lithium-ion battery that includes an anode with phenol formaldehyde as a binder material. The use of phenol formaldehyde, either alone or mixed with polyvinylidene fluoride (PVDF), helps to reduce the risk of thermal runaway and rupture during charging and discharging.
