Lead-acid battery electric vehicle battery development process of lead-acid batteries created by the French Plante (G.Plante). In 1860 he sent the samples to the French Academy of Sciences. In 1873, DC generator advent of lead-acid batteries only gradually toward practical use. 1910, lead-acid battery production by two large driving force, first began to do to start a car battery, lighting, ignition purposes; the second is the telephone industry using lead-acid batteries as a backup power source, asking them to safe, reliable, and can batteries used for many years. Since then the field of lead-acid batteries used in various cars, motorcycles, railway, mining, communications and so on. In 1860, Plante (G.Plante) achieved by repeated charge and discharge grids form an active substance in dilute sulfuric acid as the electrolyte of the first lead-acid batteries. In 1873, the advent of the DC generator, lead-acid batteries since a reliable power supply. In 1881, the British Lung color (Sellon) invention lead-antimony alloy grid, the grid and Darfur combined dusting method, electronic battery, there's the notion paste type electrode plate. This production method is simple and feasible, Xiangshan electronic scale battery, ease of production. In 1882, Cladstone and vulcanization Tribe proposed theory, since the establishment of a recognized chemical reaction. In 1886, udor and Lucas completed a convenient method of forming a positive plate system (plus corrosive electrolyte). In 1910, Exide launched tubular positive plate. In 1935, Haring invention and Thomas lead-antimony alloy grid. 1935 Slegler invention instead of hard glass tube hose previously used for tube plate. In 1970, Deviff create the first VRLA batteries with depleted liquid type structure. Above content provided by Hebei Tianyi Electric Co., Ltd., we hope to help a friend in the same industry. Electric vehicle battery failure is what caused the failure? 1, irreversible sulfation battery discharge, discharge after long-term storage, or storage, the plate will produce a coarse state in the discharge of lead sulfate dissolved, recrystallization, it is difficult to accept the charging of lead sulfate crystals This phenomenon is called irreversible sulfation. Severe electrode degradation, can not be charged. 2, premature capacity loss when used as a low-antimony or lead-calcium alloy grid, the battery used in the early stages (about 20 cycles), the emergence of the phenomenon of a sudden drop in capacity, electronic said Raymond Hui battery, the battery failure. 3, the active substance antimony antimony serious accumulation of the positive electrode plate with the charging and discharging cycle, is oxidized to ionic moieties, glass electronic scale battery, with the electrolyte and the negative electrode to the negative active material reduction, since the electrolyte hydrogen ions in the lead-antimony than in more easily reduced to generate hydrogen, and therefore accumulate after antimony, when most of the current battery charge are used for water decomposition, the battery is not charging properly and failure.
