IDTechEx's report provides an appraisal of the various alternative technologies, highlighting their respective strengths and weaknesses and the value proposition they offer, or could offer, to specific applications and markets, and covers the players active in each area. Other EV segments will have greater scope to incorporate, replace or hybridise with alternative technologies such as LTO, niobium anodes, Na-ion and supercapacitors. Silicon anode, lithium-metal and solid-state technologies are set to play increasingly prominent roles in the BEV market through the second half of the decade. The battery electric car market is of course a key target for many battery technology developments, offering the opportunity to supply a market where battery demand is forecast to grow beyond 1500 GWh by 2030. This provides an opportunity for technologies such as the redox flow battery which can more easily scale energy capacity and also affords the opportunity for using low-cost and widely available active materials. For stationary energy storage for example, there will be a growing need for longer-duration storage technologies. Debido a las excelentes características y el precio aceptable, el silicio es ahora el material ampliamente utilizado en dispositivos semiconductores. Silicio puede ser dopado con otros elementos para subir o bajar la conductividad de acuerdo a las diferentes aplicaciones. Ultimately, the combination of performance characteristics and therefore choice of technology and chemistry will come down to the needs of a specific application and market. Pieza de silicio de alta pureza a temperatura ambiente. In addition to a deep dive on silicon, Li-metal and Li-S technologies, an overview of the solid-state electrolyte technology and company landscape is provided.Īlternatives to lithium-based chemistries will generally sacrifice energy density in search of better environmental credentials, lower capital or lifetime costs, better rate capability or higher cycle life. Longevity is even more problematic for the Li-S batteries which replace the intercalation cathodes in Li-ion with a conversion-type sulphur cathode. However, both silicon and lithium-metal have posed serious problems to longevity, which has delayed and limited commercial adoption so far. The excitement stems primarily from the possibility of these anode materials significantly improving energy density, though enhancements to rate capability, safety and even cost are being sought. Two of the most exciting material developments to Li-ion are the development and adoption of silicon anodes and Li-metal anodes, the latter often but not always in conjunction with solid-electrolytes. Cathode and anode choices, cell design improvements, whether rate of energy density improvement will continue and how high energy density can go are questions addressed in this report. Given the importance of the EV market, specifically battery electric cars, on determining battery demand, Li-ion is forecast to maintain its dominant position. Advanced Li-ion refers to silicon and Li-metal anodes, solid-electrolytes, high-Ni and LNMO cathodes as well as various cell design factors.
