The Most Important Parameters for Selecting the Ideal Lithium Polymer Battery
Lithium-ion and lithium-polymer batteries currently set the standards in the battery market in terms of performance, cell voltage and service life. While lithium ion batteries are thought to power the vast majority of our cars in the future, lithium polymer batteries are already supplying power to our mobile phones and laptops today.
Both cell types are based on an identical cell chemistry, meaning the chemical processes during charging and discharging of the cell are the same. However, lithium ion and lithium polymer cells differ in their construction. Lithium ion cells use a sturdy metal housing of standardized size. The design of lithium polymer cells offers much greater flexibility: instead of a rigid housing, the flat, sandwich-type cells are enclosed by a thin layer of plastic-laminated aluminium foil. This design enables the production of lithium polymer cells in a wide range of different shapes and sizes.
