Unlike more common batteries, solid-electrolyte batteries
contain a solid rather than liquid electrolyte. The illustration
shows that the solid-electrolyte battery has a case-neutral
design, contains a stainless-steel housing, and has a plastic
insulator on the inside of the case (Figure 1). A lithium
envelope within the plastic serves as the anode, and also
contains the battery's depolarizer. The case has several
hermetic "feed-throughs" that allow the current collector leads
from both the anode and cathode to pass, and they are positioned
in the center of the cell. Both the cathode and anode leads are
on the top of the battery.Chemistry Applying significant
pressures to the cathode, electrolyte, and anode, forcing them
into a circular disk form. The cells must be held at spring
pressure within a stainless-steel container. Another feature of
the solid-electrolyte battery includes a case-positive design.
The development of the solid-electrolyte (rather than a liquid
electrolyte) battery began because scientis
