Energy Storage Solutions

PPM Power supplies Lithium-ion capacitors as energy storage solutions which have a hybrid structure that uses the same activated carbon as electric double layer capacitors for the positive electrode and the same carbon as Lithium-ion batteries for the negative electrode.

Due to the structure and advanced pre-doping technology, it has resulted in performance that combines the advantages of both at a high energy density, high output density and rapid charging and discharging and a variety of application uses whilst ensuring high safety.

Our Lithium-ion Prismatic products offer an opportunity to drive down costs by diminishing the number of manufacturing steps, reduce weight and costs whilst optimising packaging efficiency and applications.
