Aqueous Battery Technology (Science and Technology)
Why In News:
Indian researchers have made significant advances in electrolyte engineering for durable and affordable aqueous batteries.
These batteries use water-based electrolytes, making them safer, low-cost, and environmentally friendly.
What are Aqueous Batteries?
Definition: Batteries that use water-based (aqueous) electrolytes instead of organic solvent-based electrolytes used in conventional lithium-ion batteries.
Key Advantage: Non-flammable, non-toxic, and lower manufacturing cost compared to lithium-ion batteries.
Types: Aqueous zinc-ion batteries, aqueous sodium-ion batteries, and aqueous lithium-ion batteries are being developed for grid-scale applications.
Applications: Grid-level energy storage for renewable energy (solar, wind), consumer electronics, electric vehicles (EVs), and off-grid power systems.
Significance for India
Energy Storage Mission: India has a target of 500 GW of non-fossil fuel electricity capacity by 2030, requiring massive grid storage infrastructure.
Import Reduction: Reducing dependence on cobalt, nickel, and lithium by developing water-based alternatives strengthens strategic energy autonomy.
PM-KUSUM Scheme: Solar pumps and off-grid systems under PM-KUSUM can benefit from affordable local battery storage.
Key Facts for Prelims
PM E-DRIVE scheme:Speed up the transition to EVs by offering upfront incentives for EV purchases and encouraging the development of charging infrastructure.
