The internal resistance of battery comprises the polarization resistance that Ohmage and electrode are showed when electrochemical reaction, Ohmage is made up of the contact resistance of pole piece, electrolytic solution, barrier film resistance and each several part part, and wherein the resistance of pole piece occupies very big ratio in the internal resistance of battery.The internal resistance conference of battery causes bad influences such as discharge platform is low, high rate performance difference to battery.Therefore when selecting the design of electrode material and electrode, the resistance of pole piece should be low as far as possible.
The preparation of battery pole piece is first important step in the entire cell manufacture craft, and wherein the prescription of electrode, raw-material selection etc. are played decisive role to the overall performance of battery.
At present, usually estimate the selection of pole piece and design and whether rationally be several design practice in battery, performance by test battery verifies, sometimes in order to determine that a scheme need carry out the experiment of several schemes simultaneously, and so not only expend energy on but also waste resource.
Summary of the invention
The present invention provides a kind of method for testing resistance of battery positive/negative plate and device thereof for solving the problem that prior art exists.
The objective of the invention is to set up a kind of method of test battery pole piece resistance, the method is simple, quick, can be used as a kind of householder method of battery design, can test deisgn product at the pole piece initial stage of making.
Method for testing resistance of battery positive/negative plate of the present invention adopts following technical scheme:
Method for testing resistance of battery positive/negative plate, adopt ohmmeter to carry out internal resistance measurement, be characterized in: during test, with anchor clamps self-contained battery pole piece, and battery pole piece is contacted with the baffle of anchor clamps, pole that baffle is drawn and internal resistance epiphase connect, and directly read positive/negative plate resistance value in the battery by the internal resistance table.
Method for testing resistance of battery positive/negative plate of the present invention can also adopt following technical measures:
Above-mentioned method for testing resistance of battery positive/negative plate is characterized in: battery positive/negative plate is the electrode that adopts coating method to make.
Above-mentioned method for testing resistance of battery positive/negative plate is characterized in: the preparation of battery positive/negative plate is after both positive and negative polarity active substance, conductive agent, adhesive are mixed, and is coated in to roll on the collector to make.
Another object of the present invention provides a kind of simple in structure, easy to operate a kind of resistance of battery positive/negative plate proving installation.
Resistance of battery positive/negative plate proving installation of the present invention adopts following technical scheme:
The resistance of battery positive/negative plate proving installation comprises insulating base and baffle, is characterized in: the resistance test device has insulation following and the seat of honour, and baffle is equipped with at the following seat and the seat of honour, and the following seat and the seat of honour are fixed with securing member.
