On the Use of Panasonic Batteries
Panasonic batteries are not unfamiliar to everyone, and many people have used Panasonic batteries in their lives, but are they really right? To know that the correct use of Panasonic batteries can be well extended, let Panasonic battery manufacturers summarize some Panasonic batteries for you today. Now!
(1) When carbon is added to the negative active material to charge/discharge with 5 s pulse and 1 s gap time cycle, the main process of Panasonic battery in this case is the capacitive charge/discharge of the double layer formed on the surface of the electrode.
(2) The main process of charging/discharging 60 s cycle with 30s or 50s pulse [i.e. 3% or 5% (DOD) discharge depth], in which case, depends on the characteristic parameters of the battery, such as the electrochemical reaction of lead oxidation (discharging time) or the reduction reaction of lead S04 (charging time) or the chemical reaction of formation and dissolution of lead S04. The number of cycles completed in a cycle group can be terminated by several factors. It can be compared with the cycle stability of negative capacitive charging/discharging batteries.
(3) Two parallel energy systems are formed on the negative pole: one is a capacitive carbon system, which has a small capacity (Ah) but can discharge at a high rate; the other is an electrochemical lead system, which has a high capacity but can work at a low rate. In order to ensure the high performance of the negative pole, there should be an optimum proportion between the two systems.
(4) Carbon is added to the active material of the negative pole, which affects the cycle performance of the battery through the structure of the active material of the negative pole and different ways. The addition of TDA activated carbon particles can enter the skeleton structure of human negative active material and extend to the plate to form capacitive charging/discharging. The cycle performance of the battery was improved. AC3 fine carbon black powder particles can be adsorbed on the surface of lead particles to change the structure of the negative active material, so as to improve the performance of the battery.
_The addition of carbon into the negative active material can change its L-gap system. The average pore size of the negative active material is less than lptm. The skeleton structure of the negative active material as a semi-permeable membrane can block SO:- close to the L in the negative active material. Pb2 + is formed in the pore and the solution in the pore is positively charged. In order to restore the electrical neutrality, H'migrates from the solution in Ll to the whole electrolyte. At this time, the solution in the pore is alkaline. In this case, tet-PbO < a-PbO) is formed in the pore, which seriously hinders the oxidation of lead. According to the literature, AC3 carbon black was added to the negative active material, and membrane pore and tet-PbO () were formed on the negative active material after circulation. LeadO.
These basic reactions are all on the negative electrodes of HRPSoC cycle: Panasonic batteries include capacitive charge/discharge of double layers, chemical and electrochemical reactions of lead oxidation, reduction reaction of lead S04 and recrystallization of PBS()+ and hydrochlorination of the negative electrodes in solution. These basic processes are equally important. The reaction rate of these reactions varies with the different uses of the battery. At the same time, the modification of the manufacturing process of the negative plate is required to suit the various uses of the battery.
