Recognizing the threat of rising temperature brought by climate change and what, as a developed country, the UK’s fair contribution to the global effort should be, the UK Government has set a legally binding target of 80 percent CO2 reduction by 2050 compared to 1990. The Committee on Climate Change (CCC) is an independent body that advises the UK Government on setting and meeting carbon reduction targets and on preparing for the impacts of climate change.

Assessment of Performance and Safety on Lithium Ion Pouch Battery Under Various Test Conditions

In recent years, lithium ion polymer cells in pouch format have found increasing use in portable consumer electronics. They are commonly being referred to as lithium polymer cells (hereafter referred as Li-Poly), although these cells are not of the true polymer types1,2. Compared to conventional batteries such as nickel cadmium systems, Li-Poly cell designs provide the highest specific energy (>220 Wh/kg) and energy density (>450 Wh/L) of all commercially available designs3. From a safety and fire protection standpoint, a high energy density coupled with a flammable organic, rather than aqueous, electrolyte has created a number of new challenges with regard to the design, storage and handling of batteries containing lithium ion cells.
