Truewin Technology looked at improving the cell performance and applied STOBA (Self Terminated Oligomers with Hyper-Branched Architecture) and Foresight’s high porosity separator into our customized battery cells.
Truewin Technology uses Foresight Energy Technology’s battery isolating film which provides exceptional separator porosity of 52%, which is 7% higher than most other battery isolating films in the market (45%). By increasing porosity of the battery diaphragm, it increases the amount of electrolyte and passage for lithium-ion to propagate faster from positive to negative pole. Thus, extending battery cycle life by decreasing electrochemical impedance. The high permeability of Foresight’s battery separator also increases discharge (and charge) C-rate, enhancing the performance of UPS’ key requirement. Lastly, higher porosity increases lithium-ion dispersion and decreases lithium dendrite formation, which makes the batteries safer.
