Electrochemical experiments that intend to characterise the state of charge (SOC) of lead–acid battery positive plates are presented.These
experiments are designed for potential battery plate production quality control and in situ monitoring of battery condition.A small size probe,
consisting of a counter and a reference electrode encased in a glass body ending to a fine aperture tip and pressed onto the specimen,was used
to apply cathodic galvanostatic pulses on positive plate battery samples.Although this probe arrangement is similar to that of a coulometric
thickness gauge,the porous nature of the battery plate results eventually in full discharge of the entire specimen.However,during the initial
stages of specimen discharge using the contact probe,a potential arrest was observed for fully charged and partially discharged samples and it
was attributed to the time needed for the thickness of a PbSO4 film formed during discharge and the corresponding resistance under the probe’s
tip to reach a critical value for the discharge to spread to the rest of the sample.The duration of this potential arrest was found to be related to
the positive plate’s SOC indicating the possibility of using the technique in positive plate quality control or in situ monitoring.2002 Elsevier

Rechargeable batteries are receiving increasing attention
as the demand for environmentally clean energy sources
expands.Traditional applications include starting,lighting
and ignition of automobiles,electric traction and uninterruptible
power supplies used in telecommunications,substations,
chemical plants and nuclear installations [1–5].
The emerging electric vehicle technology aiming to the
development of fuel-cell/battery hybrid electric cars [6] has
further stimulated research into rechargeable batteries.
Despite the emergence of new battery types and fuel-cells,
the lead–acid battery is still the most attractive option from
an economic point of view and is expected to dominate the
above mentioned applications for the foreseeable future.

现在演示的是对铅酸蓄电池正极电荷状态特点的电化学实验研究.设计这些实验能对潜在蓄电池极板的生产进行质量监控,并且可就地监测电池状况.可用一小型探针对样品电池正极加以负极动态脉冲.将一相反电极和一对照电极包裹在玻璃体中,底部留一孔隙,与样品压紧,就可制成探针.
尽管该探针的设置与电量测厚仪相似,但蓄电池极板的多孔属性最终会导致其与整个样品完全分离.但是在用接触性探针使样品放电这一过程的初期,可在完全充电和部分放电的采样中观察到电势静止.
这一现象可归因于在放电过程中用于形成一定的PbSO4膜厚度所需时间,以及探针达放电临界值从尖端传导到样品其余部分时产生的相应电阻.
我们发现,电势静止所持续的时间与正极的电荷状态有关.该电荷状态预示着对正极运用技术手段进行质量控制,以及在原地进行监测是能够实现的.
