A polymer electrolyte is a polymer matrix capable of ion conduction. [1] Much like other types of electrolyte—liquid and solid-state—polymer electrolytes aid in movement of charge between the anode and cathode of a cell.
Under certain conditions, some battery chemistries are at risk of thermal runaway, leading to cell rupture or combustion.As thermal runaway is determined not only by cell chemistry but also cell size, cell design and charge, only the worst-case values are reflected here.
A lithium polymer battery, or more correctly, lithium-ion polymer battery (abbreviated as LiPo, LIP, Li-poly, lithium-poly, and others), is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte. Highly conductive semisolid polymers form this electrolyte.
Organic batteries are an alternative to the metal reaction battery technologies, and much research is taking place in this area. An article titled "Plastic-Metal Batteries: New promise for the electric car" [4] wrote in 1982: "Two different organic polymers are being investigated for possible use in batteries" and indicated that the demo he gave was based on work begun in 1976.
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.

One problem with the lithium–sulfur design is that when the sulfur in the cathode absorbs lithium, volume expansion of the Li x S compositions occurs, and predicted volume expansion of Li 2 S is nearly 80% of the volume of the original sulfur. [35] This causes large mechanical stresses on the cathode, which is a major cause of rapid degradation.
