Customer ServiceThe possibilities of fast charging of lithium-ion batteries are determined, first of all, by the kinetics of current-producing processes during charging, and, therefore, depend on the nature of the electrochemical system, the structure of the electrodes, and separators.
The effect of a preload force and SOC on the mechanical response of lithium-ion pouch cells during quasi-static indentation tests was examined in this study. Furthermore, the effect of reversible swelling and the related change of thickness was investigated by charging/discharging of pouch cells while applying a preload force.
Rupture of the pouch and separator melting are the two key factors for the initiation of TR during overcharge process. Therefore, proper pressure relief design and thermal stable separator should be developed to improve the overcharge performance of lithium-ion batteries.
As a rule, the positive electrode of a lithium-ion battery consists of a porous active layer deposited on an aluminum current conductor. The active layer, in turn, consists of particles of active material, an electrically conductive additive and a binder. The pore space of the active layer is filled with liquid (or polymer) electrolyte.
The overcharge-induced TR process of lithium-ion batteries is an electrochemical-thermal coupled process accompanied with ohmic heat generation, gas generation and a series of exothermic reactions .
In this paper, the overcharge performance of a commercial pouch lithium-ion battery with Li y (NiCoMn) 1/3 O 2 -Li y Mn 2 O 4 composite cathode and graphite anode is evaluated under various test conditions, considering the effects of charging current, restraining plate and heat dissipation.
