Knowledge-based improvements of Li-ion battery cost, performance, recyclability and safety are needed to enable electric vehicles to rapidly gain market share and reduce CO2 emissions. SPIDER’s advanced, low-cost (75 €/kWh by 2030) battery technology is predicted to bring energy density to ~ 450 Wh/kg by 2030 and power density to 800 W/kg. It operates at a lower, and thus safer, voltage, which enables the use of novel, highly conductive and intrinsically safe liquid electrolytes.
Moreover, SPIDER overcomes one of the main Li-ion ageing mechanisms for silicon based anodes: notably, the loss of cyclable lithium, which should increase lifetime to 2000 cycles by 2022 for first life applications with further usefulness up to 5000 cycles in second life (stationary energy storage). In addition, SPIDER’s classic cell manufacturing process with liquid electrolyte will be readily transferable to industry, unlike solid electrolyte designs, which still require the development of complex manufacturing processes.Finally, SPIDER batteries will be designed to be 60% recyclable by weight, and a dedicated recycling process will be developed and evaluated during SPIDER.
