Pratik Kamdar, CEO & Co-Founder, Neuron Energy said, "Batteries have become a mainstay application across the majority of segments and products we use and consume. They play a significant role in consumer electronics, power tools, electric mobility, and military and defence applications. Batteries have facilitated innovative products, such as bulbs with a 5-hour power backup and cars with a range capacity of 1000 km on a single charge. Battery technology has evolved significantly from LFP Chemistry, NMC Chemistry to Sodium Ion, Hydrogen fuels, Lithium Cobalt oxide, and more.

"This transformation in chemistry is a continuous process, and we expect each chemistry/technology to find its use case in a specific application. All chemistries/technologies will coexist, working for different applications. Once energy storage
and data centres transition completely to lithium-ion from lead-acid, there will be a substantial reduction in hazardous output at manufacturing units. Sustainability initiatives should encompass broader adoption and the creation of a clean ecosystem for batteries, including initiatives in cell manufacturing, assembly, and recycling," he added. 

Batteries in Renewable Energy

The integration of renewable energy sources, such as solar and wind, into the power grid necessitated effective energy storage solutions. Batteries stepped into this role as key players in balancing the nature of renewable energy production. Large-scale lithium-ion battery installations, coupled with advancements in flow batteries and other storage technologies, offer grid operators the flexibility needed to maintain a stable power supply. This symbiotic relationship between batteries and renewable energy sources represents a critical step towards a sustainable and resilient energy infrastructure.

Verma said, “Lithium-ion batteries, by powering electric vehicles and storing renewable energy, are pivotal to reducing carbon emissions and achieving energy sustainability. The virtually infinite recyclability of battery metals and minerals turn the battery waste pipeline into a gold rush of future materials.”

Lithium-ion battery technology has evolved dramatically since its debut in mobile devices. Advancements in electrode materials, like cobalt to nickel, enhanced energy density and safety. Transitioning to electric vehicles demanded higher capacity, leading to improved cathode and anode designs. Tesla's Gigafactories spurred economies of scale, driving down costs. Grid-scale applications for renewable energy storage emerged, requiring robust, long-lasting batteries. Innovations in solid-state batteries promise safer and more efficient alternatives. Overall, from pocket-sized devices to electric mobility and sustainable energy storage, the evolution of lithium-ion batteries showcases relentless innovation, expanding applications, and a crucial role in the transition to a cleaner, electrified future, Singh said.
