Zwitterions May Be Key To Solid-State Batteries
Guy Youngs Liquid electrolytes have been key EV batteries for some time now and the lithium-ion formula is the most important component. There are a lot of different formulae that do various things such as the removal of toxic inputs from the supply chain, or reductions in weight, elimination of fire hazards, and cutting costs.
The ultimate goal is to combine all these improvements in one electrolyte, but solid state or semi solid state batteries are appearing before that goal can be achieved and they promise to revolutionize the battery market. But, getting the electrons to move about within a solid is difficult at best. And that’s where Zwitterions come in.

CATL Launches Production of Sodium-Ion Batteries
Jack Hao Saying it has solved core manufacturing challenges, CATL said it will start mass production of sodium-Ion batteries this year. This marks sodium-ion technology’s shift from a backup option to mainstream use. The company says sodium-ion batteries show strong potential for extreme weather and energy storage.
Volatile lithium carbonate prices have pushed the industry to hunt for alternatives and secure supply chains. Sodium offers clear cost advantages and better cold-weather performance. As CATL, BYD and other leading players now enter with full supply chains, technical hurdles are being cleared, and commercialization is picking up speed. A new “sodium-lithium parallel” energy landscape is taking shape.
This shift from backup option to mainstream strategy reflects CATL’s heavy investment and bullish market outlook. By 2025, the company had poured nearly $1.47 billion US dollars (10 billion yuan) into sodium-ion R&D. Chairman Zeng Yuqun expects the technology to capture 30–40% of the existing battery market. In CATL’s vision, sodium-ion batteries are no longer just a supplement to lithium, but a key force in reshaping the market.

Ashok Leyland Takes Major Step Toward EV Leadership
Aditya Kondejkar Ashok Leyland’s move to develop and assemble its own battery packs marks one of its most strategically significant announcements in recent years. As India transitions toward a cleaner, multi-fuel commercial mobility ecosystem, this decision places the company at the center of the country’s electric commercial vehicle (ECV) transformation. The implications extend across technology, cost structure, competitive positioning, and long-term industry dominance.
At the core, battery packs account for 35–45% of an electric vehicle’s total cost, making them the single most influential factor in pricing and margins. By internalizing battery pack development, Ashok Leyland is aiming to break its dependence on third-party suppliers, reduce bill-of-materials cost, and secure tighter control over the EV value chain. This is crucial as global cell prices fluctuate and supply chains remain vulnerable to geopolitical shifts. In-house pack assembly gives the company cost stability, greater design flexibility, and freedom to optimize packs specifically for Indian duty cycles—ranging from stop-and-go urban e-buses to long-haul e-LCVs and future heavy-duty platforms.
