Solid-state and sodium-ion batteries are set to be the only commercialized emerging battery technologies by 2030, according to Bain & Company. The consultancy firm emphasizes that solid-state batteries promise higher energy density, improved safety, faster charging, and potentially longer lifespan compared to NMC batteries.
Solid-State Batteries: Future Potential
Solid-state batteries promise significantly higher energy density. They also offer improved safety and faster charging times. Many in the industry see these batteries as a game-changer for Electric Vehicles (EVs). However, recent developments have only shown initial proofs of concept. This follows multiple delays, and commercial releases are expected within three to four years.
Sodium-ion Batteries: Emerging Competitor
Sodium-ion batteries have shown improvements in energy density. Prototypes are now comparable to LFP batteries. Bain expects sodium-ion batteries to be commercially available by the first half of 2025. These batteries offer a new avenue for EV manufacturers looking for alternative energy sources.
Market Impact and Expectations
Mahadevan Seetharaman, a partner at Bain, stated that battery costs are the primary driver for OEMs. The choice of battery type can significantly affect product performance. With ongoing changes in battery chemistries, especially Lithium-ion batteries, OEMs face critical decisions. These include whether to develop batteries in-house or to collaborate with other companies.
Global demand for EV batteries is projected to quadruple, reaching 4,100GWh by 2030. This surge is largely due to rising car sales. Volkswagen’s PowerCo and QuantumScape recently announced a collaboration. This partnership aims to manufacture up to 40GWh of batteries annually, using QuantumScape’s solid-state technology. There is also an option to expand up to 80GWh per year.
QuantumScape Collaboration
The QuantumScape and PowerCo agreement replaces a previous joint venture. They believe this collaboration is the fastest way to achieve gigawatt-hour-scale production. The aim is to meet the growing global demand for better EV batteries.
In summary, both solid-state and sodium-ion batteries are poised to be the leading commercialized technologies in the EV market by 2030. As advancements continue, these technologies promise to reshape the future landscape of energy storage and Electric Vehicles.
