Battery, in experiment preliminary stage, such as the screening of material, can obtain effective conclusion, and then carry out by electro-chemical test
Follow-up battery assembly experiment.And electro-chemical test only needs to prepare working electrode, it is possible to targetedly to anode into
Row research, the preparation of working electrode is compared to the preparation of battery, and influence factor will be lacked, and all be relatively easy to control, thus the knot drawn
By having very much a reference value, therefore the preparation of anode working electrode just seems more crucial.
Electrochemical analysis test is indispensable means during electrochemical research, during the test, the temperature of test system
Degree control is more crucial.The temperature of test system electrolyte is usually controlled by the method for water-bath during the test, still
If testing under low temperature environment and being less than the chemical property of working electrode under environment temperature in other words, the method for water-bath is not obviously up to
To requiring, carry out control system temperature if whole test system is placed in cryogenic box, be so unfavorable for observing electrode surface again
Change.
