Description
Technical Field

Background
Lead-acid batteries (LA) are rechargeable batteries widely used in various fields of national economy, and are batteries in which electrodes are mainly made of lead and its oxides, and an electrolyte is a sulfuric acid solution. In the charging state of the lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the discharge state, the main components of the positive electrode and the negative electrode are lead sulfate and unreacted lead or lead dioxide.
The monitoring of the working state of the lead-acid battery by using the reference electrode has very important significance for the production, research and development and fault diagnosis and analysis of the lead-acid battery. The reference electrode widely used in the lead-acid battery industry at present mainly comprises Hg/Hg 2 SO 4 、Ag/Ag 2 SO 4 And a metallic cadmium electrode. Hg/Hg 2 SO 4 The electrode is widely applied to laboratory research and development of lead-acid batteries due to high stability, reliability and repeatability. Meanwhile, the popularization of the mercury-free lithium ion battery in the production and use processes of the battery is influenced due to the fact that the mercury-free lithium ion battery contains Hg element with high toxicity. Ag/Ag 2 SO 4 The electrode overcomes Hg/Hg 2 SO 4 The toxicity of the electrode is combined with Hg/Hg 2 SO 4 The stable and reliable reproducibility of the electrode is high, but due to Ag 2 SO 4 The silver sulfate has high solubility in a sulfuric acid solution, silver sulfate solid can be gradually dissolved and disappear in the using process, so that the service life of the silver sulfate solid is difficult to guarantee, and the dissolved silver ions are easy to be reduced on the negative electrode of the lead-acid battery and deposited on the surface of the negative electrode, so that the speed of hydrogen separated out from the negative electrode is accelerated, and the adverse effect is brought to the performance of the lead-acid battery. The most important advantage of the metal cadmium electrode is convenience, but the cadmium has high toxicity due to poor potential stability, so that the metal cadmium electrode has certain application only in occasions with low requirements on a reference electrode, such as the production process of a lead-acid battery.
With the global popularization of renewable energy sources, energy storage becomes necessary to overcome the intermittent problem of renewable energy sources. Electrochemical energy storage is also increasingly popularized as an important energy storage mode. The lead-acid battery is widely regarded as a mature, economic, safe, stable and reliable electrochemical system applied to the field of energy storage. But the traditional lead-acid battery is difficult to adapt to the requirements of new era energy storage on chemical power sources. In order to have economic applicability, the requirement on the cycle life of the lead-acid battery for energy storage is improved to more than 3000 times and even 6000 times, and the service life is 10-20 years, which is 2-4 times that of the traditional lead-acid battery for energy storage. In order to further exploit the potential and improve the performance of lead-acid batteries, it is necessary to fully absorb the recent achievements in other scientific and technical fields. If the lead-acid battery which is used in a rough manner in the past can be managed finely by utilizing an intelligent monitoring technology, the working state of the battery can be monitored, found and adjusted in time, and the performance and the service life of the battery can be obviously improved.
Therefore, a reference electrode that is stable, reliable, fast in response, compatible with the existing lead-acid battery industry, economical, safe, easy to miniaturize or miniaturize, and easy to install in a lead-acid battery has become a need of current research.
