Lithium battery forklift and auto start the lithium battery combination structure
Car is lithium battery with 12 v lithium batteries are composed of six single cells in series, each single case of nominal voltage is 2 v, series into the 12 v power supply, mainly composed of plate, electrolyte, lattice shell, electrode, and other parts. Lithium battery forklift series is 2 v monomer into 24 v, 48 v, 80 v, has the extremely high current, high current discharge, to be able to work for a long time, meet the demand of daily vehicle handling, plate is divided into two kinds of positive plate and negative plate. Lithium battery charging process is relying on the plate on the active material and electrolyte in the chemical reaction of sulfuric acid. On the positive plate of active substances are dark brown lead dioxide ( PbO2） , the active material on the negative plate is spongy, caesious pure lead ( Pb) , our everyday is used in the automobile starting batteries, only momentary boot, composition structure and forklift battery is not the same, if the car lithium-ion batteries used in electric forklift, Pierce plates may only, time is very short, lithium battery forklift to join antimony purpose is to improve the grid frame mechanical strength and casting performance, but the antimony has certain side effects, antimony easy parsing from the positive plate grid frame caused by the lithium battery to discharge and the expansion of the fence, decay, thus affecting the service life of lithium-ion batteries. The thickness of the negative plate of 1. 8 mm, positive plate of 2. 2 mm, in order to improve the capacity of lithium batteries, abroad mostly adopts the thickness of 1. 1 ~ 1. 5 mm thin plate. In addition, in order to improve the capacity of lithium-ion batteries, will be more positive and negative plates in parallel, composed of positive and negative plate group. In each single cell battery, the number of negative plate is always a more than positive plate and positive plate between negative plate, make its discharge evenly on both sides, otherwise due to the positive plate mechanical strength is poor, single work can be made on both sides of the active material volume change, resulting in plate bending. Above is car lithium-ion batteries with forklift batteries a few and the ways of into.
