Lithium is ideal as electrode material for batteries
due to its physical and chemical properties.
It is characterised by the fact that it posesses the
highest negative standard potential and the highest
electrochemical equivalent of all metals.
At the same time however it is also very reactive
which makes handling lithium as well as contact
with it very expensive. Today we can find many
different primary battery systems with a
lithium basis. Here we can present to you our
Lithium Manganese Dioxide
and Lithium Thionyl Chloride industry batteries.
Lithium Manganese Dioxide
(LiMnO2) is one of the first
battery systems with a lithium
cathode system which were
manufactured industrially.
Today we mainly find cells in bobbin and winding
technology as well as with coin cells and the
9 volt block. The energy density amounts roughly
to 200/300 Wh/kg. The internal resistance is higher
than with other lithium batteries due to the type.
Lithium Thionyl Chloride (Li-SOC12) batteries
have the highest energy density of all
lithium battery systems of up to 500Wh/kg.
Today, these batteries are one of the most reliable
energy sources in low-load conditions.
The most common type is the cylindrical cell.
Important features:
- A high and stable open circuit and working
voltage.
- Versatile discharge rate (several
microamperes with LiMnO2 up to 10A pulse
current with Lithium sulphur dioxide.)
- A high working tempature range according to
the type 60 °C to +85 °C
- Low self-discharge rate
- A long operating life, typically
5 years to 15 years
- A high energy density
- Many types are not subject to
transport restrictions.
