Abstract

The present disclosure provides a method for measuring an internal resistance of a battery, after discharging/charging the battery under a preset constant-current, acquiring voltages of the battery within a period from ending the discharging/charging to a time when the voltage reaches stable, and then calculating different corresponding internal resistances caused by ohmic polarization, electrochemical polarization and concentration polarization separately. Since it is different for the orders of the magnitude of the characteristic time which these different polarizations need to get back into new equilibrium state after ending the discharging/charging, the method of the present disclosure classifies the internal resistances caused by these polarizations and calculated different internal resistances corresponding to the polarizations. Both the comparison with a result measured by other method and multiple embodiments in the application justify that the method in the present disclosure has high reliability and strong practicability.

The present invention relates to a preparation method of ionic liquids, particularly to a one-step reaction method used for synthesizing quaternary ammonium compounds or quaternary phosphonium compounds. In the method, a nitrogenous or phosphorous compound, a proton compound, and a carbonate ester are added into a reactor simultaneously to synthesize corresponding the quaternary ammonium ionic liquid or the quaternary phosphonium ionic liquid through said one-step reaction, i.e., ‘one-pot method’ reaction, during which three reactants are involved. The present invention also provides a lithium ion secondary battery comprising the ionic liquid prepared by above-mentioned preparation method. The ionic liquid preparation method of the present invention can widen the choice range of raw materials needed when preparing ionic liquids, and further widen the synthesized ionic liquid species.

Abstract

A battery relating to the field of batteries and comprising a battery module (2), a cooling liquid (11) and a battery container (1). The battery module (2) and cooling liquid (11) are each provided within the battery container (1), and the battery module (2) is at least partially immersed in the cooling liquid (11). A liquid sealing layer (12) comprising a barrier liquid covers the cooling liquid (11). The latent heat of vaporization of the cooling liquid rapidly carries away heat released by a battery undergoing thermal runaway, thereby avoiding a heat buildup which causes a constant spreading of battery thermal runaway, thus having a protective effect on the battery.
