Description

technical field [0001] The embodiments of the present invention relate to the technical field of lead-acid batteries, and in particular to a method for testing the electrochemical performance of plate anodes based on the new material PPTC. Background technique [0002] Energy is the basis for human survival and development. Due to the industrial revolution of nearly a hundred years, non-renewable energy sources such as oil and natural gas, which are widely used in large quantities, are facing exhaustion, prompting various forms of adjustments in the energy structure of various countries, and the search for green and renewable new energy sources and energy conversion technologies has become an important issue today. the focus of international attention. Therefore, vigorously developing new energy sources and improving traditional chemical power sources are important issues that urgently need to be overcome in the development of the 21st century.

Problems solved by technology

[0007] The improvement of battery performance largely depends on the performance improvement and development of positive and negative electrodes. In order to meet the development requirements of batteries, the modification and performance upgrade of positive and negative electrode materials are constantly being carried out in the battery material market, which urgently needs a A method that can quickly and accurately test positive and negative electrode materials. However, for the detection methods of positive and negative electrode materials, the most widely used detection methods are button batteries and assembled into complete full batteries. The accuracy of button batteries is not high, and Assembling a complete full battery is not only a long period of time, but also cumbersome to manufacture and complicated operation methods. Another defect is that the current detection method cannot comprehensively and quickly compare the electrochemical performance of the PPTC material plate anode and the traditional plate anode.
