Effect of aditives added to the electrolyte

conference paper

English

Lead-acid accumulators operate in different modes, according to their use. From this point of view it can be divided into several groups. The first of these are known as traction batteries which are used to power vehicles such as a wheelchair, golf carts, and cleaning machines. Therefore the main requirement for these batteries is a long life in “deep cycling” regime. Long life is generally indicated by the number of cycles at which the capacity of the battery is greater than 80% of the original capacity. Another type is stationary batteries. It works as backup power sources during outages of electricity. Therefore, there are high demands on the reliability and durability during continuous charging 2,3 V per cell. The last group consists of starter batteries used for starting internal combustion engines. Those must provide a large amounts of energy at the start. Under normal operating conditions, these batteries are constantly charged. In order to achieve improved physical and chemical properties of the battery, due to the requirements imposed on it, it is possible to add various additives into electrolyte (aqueous sulfuric acid solution).
