The following is a simplified description of how a battery works. Two important parts of any cell are the anode and the cathode. The cathode is a metal that is combined, naturally or in the laboratory, with oxygen—the combination is called an oxide. Iron oxide (rust), although too fragile to use in a battery, is perhaps the most familiar oxide.

How does a lithium battery work?
Lithium-ion batteries work by letting ionic lithium cross the electrolyte barrier between the battery’s anode and cathode (the positive and negative end s). This electrolyte is a liquid in standard lithium-ion batteries. A solid-state battery uses a solid electrolyte to regulate the lithium ions instead of a liquid one.
What is the difference between a solid state battery and a lithium ion battery?
A solid-state battery uses a solid electrolyte to regulate the lithium ions instead of a liquid one. So the main difference between a lithium-ion battery and a solid-state battery lies within the electrolyte. While lithium-ion batteries (and most other batteries) use a liquid electrolyte, solid-state batteries use a solid electrolyte.
What is the material between two electrodes?
These two electrodes are made of an electrically conductive material. Between these two electrodes (and within them) is an electrolyte containing electrically charged particles (ions). The electrolyte allows lithium ions to travel through it to combine with the anode or cathode (depending on charging or discharging).
What is the benefit of solid state battery?
In short, the solid electrolyte used in a solid-state battery provides higher energy density, longer lifespan, and increased safety in a smaller size! Energy density measures the amount of energy a battery contains proportional to its weight.
How much more energy density does a solid state battery have?
Solid-state batteries are said to be capable of delivering 2.5 times more energy density of current lithium-ion tech. This tremendous increase in solid-state batteries’ energy density means that they will be far smaller and lighter.
Why is weight important in mobile power?
