Preventing Quality Problems
Reduction of Battery Voltage and Deterioration of Capacity
(1) Reduction of battery voltage and deterioration of capacity through contact with antistatic
conductive materials
Incidents have been reported where terminal-mounted batteries for memory backup or coin-type lithium batteries have
come into contact with antistatic conductive materials, thus forming external discharge circuits and leading to voltage drops
or capacity deterioration.
In manufacturing plants using ICs, LSI and other semiconductor components, thoroughgoing antistatic measures are taken.
Various protective materials are used to prevent static: most of them have special compounds of carbon, aluminum foil and
other metals and are therefore conductive. These protective materials are used, for example, in the form of packaging bags,
trays, mats, sheets, films, corrugated boards and resin cases.
A protective material may have a resistance ranging from 10 3 to 10 6 ? /cm, for instance. This means that if the (+) and (-)
terminals of a battery come into contact with this material, a current ranging from several milliamperes to several microamperes
will flow and the battery will discharge, causing voltage drop and capacity deterioration.
A terminal-mounted battery was inserted into a
conductive mat. The battery charge was exhausted
in several days.
