Electrolyte

These batteries can be dangerous because they are kept at high pressures and contain a flammable electrolyte.

An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air).

The electrolyte solution in a lithium-ion battery is designed to produce a flow of electrical charges between the cathode and anode.

Some modern lead-acid batteries are sealed because they never need to have any electrolyte added during their service life.

Lab tests to consider under these circumstances include serum electrolytes, serum glucose, and urine protein.
