Low-cost, high-density lithium–ion battery technology for electric vehicles
The demand for electric vehicles is growing. Cost reduction, increased range and safety, and shorter charging times are key to accelerating their market acceptance. The EU-funded SPIDER project is developing a powerful, durable and safe lithium-ion battery technology. The new, low-cost battery is expected to bring energy density to 450 Wh/kg and power density to 800 W/kg by 2030. It operates at a lower and safer voltage, and uses novel, conductive and intrinsically safe liquid electrolytes. Safety concerns are further eliminated as thermal energy dissipation can be reduced to 4 kW/kg and thermal runaway temperature increased to over 200 °C. The battery technology bypasses the loss of cyclable lithium – a main lithium-ion ageing mechanism for silicon-based anodes – by using prelithiation.
