Abstract
This invention puts forward a high energy sealing maintenance-free lead acid battery negative active substance composite material used in railroad locomotives characterizing in fine large current discharge performance under super-low temperature so as to enable the lead-acid batteries to operate under super-low temperature.
Description
Technical field: lead acid accumulator is the important component part of storage battery, and its market share accounts for 60～70% of secondary accumulator battery.Various in recent years electrical appliances require to improve constantly to battery quality, require lead acid accumulator high-energy, hermetically sealed, non-maintaining.This invention belongs to field of new.
Background technology: at the high latitude area in the three northern areas of China and the world of China, the temperature in winter can be reduced to subzero about 40 ℃, and railway locomotive moves often the several temperature interval of will jumping within a few days.The locomotive of China's use at present is to use lead acid accumulator as startup power supply, and every joint locomotive is installed 48 2V500Ah lead-acid batteries.Ministry of Railways's locomotive battery standard-required, 1700A discharge time is 30 seconds under-40 ℃ of conditions, there are two problems in this index.1) to the battery of new use if 1700A discharge 30 seconds under-40 ℃ of conditions, if after battery uses a period of time discharge time can shorten, can be less than 30 seconds, certainly will influence the normal starting of locomotive.2) not only temperature is low but also dust storm is big for the Qinghai-Tibet Railway newly opened of China, battery initial use only can discharge under ℃ condition of time-40 be difficult to guarantee the normal starting of locomotive in 30 seconds.For this reason, be necessary a kind of high-energy sealed maintenance-free lead-acid accumulator that under condition of ultralow temperature, has good heavy-current discharge performance of development and production, can satisfy that the normal use of locomotive is very necessary under the condition of ultralow temperature, the key technology that has the sealing maintenance-free lead acid battery of good starting performance under the production condition of ultralow temperature is the composition of cathode active materials of development battery, and the composition of cathode active materials of for this reason developing battery has significant meaning.
Summary of the invention: the closed lead acid accumulator composition of cathode active materials that the purpose of this invention is to provide starting battery under a kind of condition of ultralow temperature is to improve the large current discharging capability under the closed lead acid accumulator condition of ultralow temperature.The object of the present invention is achieved like this, and its characteristic is that the composition of this negative electrode active material is: 100kgPb powder+proportion is 1.1～1.15g/cm
