Description

A kind of bipolar lead-acid accumulator and the electric motor car using the battery
Technical field
The present invention relates to a kind of lead-acid accumulator and the electric motor car using the battery, more specifically, it relates to a kind of double Pole lead-acid accumulator and the electric motor car using the battery.
Background technology
Lead-acid accumulator has been obtained since the birth with its cost performance high, security reliability high and recyclable characteristic Extensive development, and occupy more than 80% share in secondary power supply market.But lead-acid accumulator there is also specific capacity it is low, The low shortcoming of specific energy.Lead-acid accumulator is typically provided multiple pole groups, and each pole group is designed with positive bus and negative bus, and And the bus-bar between the group of each pole is that n font supports link together, bus-bar consumption is very big, lead loss consumption and resistance also compared with Greatly, and electric current is to flow to bus-bar again by bridge to another pole group from pole plate, CURRENT DISTRIBUTION is uneven.In current market Dog-eat-dog, manufacturer significantly compress production cost, in the case of particularly compressing lead consumption, traditional busbar type battery The limit has been arrived in the compression of mode of production cost, it is necessary to found a new way, and is deeply excavated and is only possible to make a breakthrough.
The invention of Publication No. CN104201395A disclosed a kind of side-stand type bipolarity slicker solder on December 10th, 2014 Sour electrokinetic cell, can bring up to 96.81/kg by the theoretical specific capacity of original lead-acid battery from 83.47Ah/kg.By positive plate Grid are joined directly together with negative electrode grid, and grid uses terne metal thin slice, with plastic package framework as support, eliminate connection and use Lead, negative electrode active material uses pure tin, reduces deadweight, has saved space, makes side-stand type bipolarity slicker solder acid electrokinetic cell Actual specific capacity reaches more than 80Wh/kg, and energy density reaches more than 240Wh/L.But positive/negative plate is with a piece of in the invention On grid, smear, solidification performance difficulty, quality are difficult to ensure that.
The content of the invention
Each pole of existing lead-acid accumulator group is designed with positive bus and negative bus, and bus-bar consumption is very big, lead loss Consumption and resistance are also larger, and electric current is to flow to bus-bar again by bridge to another pole group from pole plate, and CURRENT DISTRIBUTION is not Uniformly, to overcome these defects, bus-bar can be simplified the invention provides one kind, reduces production cost, improve specific capacity and ratio Energy, improves pole plate bias current situation, suppresses the bipolar lead-acid accumulator of electrolyte stratification phenomenon, while additionally providing a kind of application The electric motor car of the battery.
The technical scheme is that:A kind of bipolar lead-acid accumulator, including cell body, multigroup pole group and some dividing plates, pole Group is placed in cell body, and cut-off is between cell body and pole group, and pole group is each other, and pole group is arranged at least two row, together Positive unipolar plate, negative unipolar plate press positive and negative attribute interfolded in the group of group pole, in the pole group of colleague, the positive unipolar plate in a pole group Electrically connected correspondingly by bipolar plates with the negative unipolar plate in consecutive roots group, the pole group of group's one outer rows of ranks in pole In, the positive unipolar plate in a pole group is electrically connected with the negative unipolar plate in same column consecutive roots group by bus-bar, in pole group's ranks In the pole group of another outer rows, the positive unipolar plate in a pole group is electrically connected with a positive bus, and in same column consecutive roots group Negative unipolar plate electrically connected with a negative bus, in each positive unipolar plate or negative unipolar plate only with bipolar plates and bus-bar in two One of person is directly connected to.The present invention compared with traditional lead acid batteries, improved, and is only continuing with battery two ends by structure Bus-bar, and be electrically connected using bipolar plates between the internal poles of battery group, reduce the consumption of bus-bar and simplify pole group Between attachment structure, correspondingly, the consumption of lead greatly reduces, pole group arrangement it is more compact, battery overall volume is made to It is smaller, specific capacity and specific energy are improved, production cost is reduced, improve pole plate bias current situation, suppress electrolyte stratification phenomenon.
