| Project Detail |
Gelion will construct an Advanced Commercial Prototyping Centre (ACPC) to produce and test a new generation of lithium batteries with sulphur-cathodes and validate with partners. Need The growing use of renewable technologies has led to a higher demand for battery energy storage. While lithium-ion batteries (LIBs) are common, lithium-sulphur (Li-S) batteries present several advantages, such as: Higher energy density: traditional LIBs can achieve a gravimetric energy density upwards of 300 Wh/kg, while Gelion’s Li-S batteries aim to achieve a gravimetric energy density of at least 400 Wh/kg. Increased safety: Li-S battery cathodes and electrolyte are more stable at high temperatures, reducing thermal runaway and explosion risks. Cost-effective supply chains: Compared to LIBs which can use expensive materials such as nickel and cobalt in their cathodes, Li-S batteries use abundant and locally available materials like sulphur and carbon in the cathode. However, traditional Li-S battery technologies are hindered by high degradation rates due to: Polysulphide shuttling, where sulphur compounds dissolves in the electrolyte and move from the cathode to the anode and degrade through a variety of mechanisms. Incompatibility with traditional electrolytes. Growth of lithium dendrites on the anode. |
