Si, pour l'instant, les batteries Li-ion restent le choix dominant pour les appareils grand public, les véhicules électriques et le stockage stationnaire, l'importance des batteries chimiques autres que celles au lithium devrait croître considérablement au cours des dix prochaines années, en particulier dans le secteur du stockage stationnaire de l'énergie. D'ici 2025, IDTechEx prévoit que >10% du marché stationnaire sera représenté par des batteries chimiques sans lithium, contre <5% en 2021.

Li-ion batteries are beginning to hit their performance ceiling, especially with regards to energy density. However, a shift in the anode materials used, namely to silicon or lithium-metal anodes, could provide a stepwise improvement to energy density. Their promise can be highlighted by looking at the high number of early-stage companies primarily developing anode materials, most being focussed on silicon, compared to other areas of Li-ion development.

L'intérêt commercial pour les anodes en silicium et les investissements dans les entreprises en démarrage se sont poursuivis jusqu'en 2021 - IDTechEx estime que 1,9 milliard de dollars de financement ont été alloués aux entreprises en démarrage dans le domaine des anodes en silicium. Au-delà des investissements, on observe également une plus grande activité concernant les entreprises qui commencent à concéder des licences sur les technologies, à nouer des relations d'approvisionnement ou à commercialiser des technologies sur les marchés d'adoption précoce, soulignant que la promesse de la technologie des anodes de silicium pourrait bientôt être réalisée.

To date, Li-ion batteries have been the go-to technology for vehicle electrification and new stationary energy storage systems. However, the supply chain for Li-ion production is coming under increasing scrutiny with bottlenecks feasible during the second half of the 2020s, creating a potential opportunity for alternative battery chemistries not reliant on lithium, cobalt, or nickel.

Energy storage technologies are undergoing a challenging transformation, vital in an emerging climate that increasingly necessitates renewable energies and recyclable hardware. Covering a wide portfolio of energy storage technologies, their history, and their outlook for the future, IDTechEx looks at how the energy storage sector has fared over the past year, and where it is headed for the next.

With the growing momentum behind the electric vehicle market comes an added importance of understanding the Li-ion batteries that power them, the variety of design choices available, and trends in their implementation.

The resilience of global electric vehicle (EV) sales during 2020 provided some optimism as to the maturing state of the electric vehicle market. However, sales are still primarily underpinned by government policy, and improvements in cost and performance to Li-ion cells and packs, not to forget other aspects of the vehicle or grid infrastructure, are needed for widespread adoption.

Limits on the amount of bioethanol and biodiesel that can be blended with conventional fossil fuels mean growth in the consumption of certain biofuels has slowed considerably over the past 5 years. However, with CO2 targets becoming increasingly stringent, and some sectors being difficult to electrify, alternative fuels are likely to still be needed over the coming years.

In this article IDTechEx provides commentary on the reference during Volkswagen's recent Power Day to their long-term strategy of employing high-manganese cathodes for their 'volume segment'. What does 'high-manganese' refer to, and how do they compare to other cathode materials?

Growth in global energy consumption has caused CO2 and greenhouse gas (GHG) emissions to rise, in turn causing an increase in average global temperatures. The combustion of fossil fuels including coal, oil, and natural gas, has been a key driver behind this, providing the underlying driver for the production and use of non-fossil alternative fuels that can help reduce emissions.

Energy storage technologies have undergone several years of sustained growth stemming from progress in markets such as consumer devices and the quest for decarbonization kick-starting growth in electric vehicle (EV) and stationary energy storage demand.

The European Commission (EC) has proposed stricter regulations regarding the sustainability of batteries.
