Conventional current collectors, Al and Cu foils have been used since the first commercial lithium-ion battery, and over the past two decades, the thickness of these current collectors has decreased in order to increase the energy density.
Lithium-ion batteries are the state-of-the-art power source for most consumer electronic devices. Current collectors are indispensable components bridging lithium-ion batteries and external circuits, greatly influencing the capacity, rate capability and long-term stability of lithium-ion batteries.
Six different types of current collector materials for batteries are reviewed. The performance, stability, cost and sustainability are compared. 2D and 3D structures of foil, mesh and foam are introduced. Future direction and opportunities for 2D and 3D current collectors are provided.
Estimated short circuit values can vary widely depending upon the test method and measurement technique. Multi-stepped discharge test methods that use a large span in current and voltage provide the best accuracy in estimating battery short circuit current and resistance.
Battery system circuit resistance, state of charge and temperature can reduce the nominal zero-voltage short circuit currents. Potentially dangerous short circuit conditions can be prevented with a better understanding of battery and circuit protection operation.
