Lit became the default alternative for battery-powered systems, but its limitations-from volatile supply chains after a short life-they are becoming more and tougher to ignore. Offgrid Energy LabsA technologically deep startup based in India, he wants to make litter was less central, especially when it comes to storing batteries.
The 7-year startup, incubated in Iit Kanpur, has developed a reserved tin-based battery system as an alternative to lithium-ion technology. Called cincgel provides 80-90% of the energy efficiency of conventional lithium batteries, but at a much lower storage level, the startup said.
As the energy demand increases around the world, countries increase efforts to increase renewable energy storage. India, as an outstanding nation in this respect, are aimed at increasing their non-flexible energy capacity-with 50 gigawatts to 500 gigawatts – Until 2030, the latest Delhi is also Aiming in 236 hours of gigawatts Battery energy storage capability up to 2031–32 and announced a 54 billion financing plan in June (about $ 612 million) for the development of 30 gigaw-hour storage systems in this country. However, like many global markets, India is facing a key challenge: China’s domination over the lithium supply chain.
OFFGRID Energy Labs bet that tin battery technology can alleviate supply restrictions by using widely available materials and offering a more profitable alternative to lithium systems.
Now the startup has collected $ 15 million in the field of financing series A to increase its activities. He plans to build a 10-hour demonstration plant in Great Britain, it is expected to be ready for the first quarter of 2026 and start commercialization of zinc in the following quarters-from Gigafactory in India planned as the next phase.
“Not only should we deal with the gap on the market from the point of view of the application, but we should also make it financially profitable, because in the past there were technologies and batteries around the world that have a solution, but they are so expensive that they are not widely accepted,” said Tejas Kusurkar, co -founder and general director offgrid Energy Labs, intelligence.
Kusurkar, who has a doctorate from Iit Kanpur, co -founded offgrid Energy Labs in 2018 at the Institute of Incubation and Innovation Incubation, together with Brindan Tulchan (also a doctorate from Iit Kanpur), Rishi Srivastava and Ankur Agarwal. The team noticed that although lithium batteries are well suitable for mobility, the stationary storage market was underestimated-and batteries are needed that are safer, more resistant and built on the supply chain, which is easier to access, said Kusurkar TechCrunch.

The startup spent the first six years, developing battery technology and so far secured over 25 IP families and over 50 IP assets on markets, including the USA, Great Britain and India, in addition to China, Australia and Japan. The battery is based on the chemistry of the zinc bromide with a reserved electrolyte based on water, which causes a low risk of fireplace.
Kusurkar said that cincgel is also able to operate longer screenshots (6-12 hours) and can last twice so long as a typical lithium-ion battery, said Kusurkar. In addition, the battery uses a carbon -based cathode for each fast charging and discharging.
Zinc in batteries is not a latest concept, and some firms have already offered zinc -based batteries, including on the NASDAQ list EOS Energy Enterprises. However, Kusurkar noticed that offgrid Energy Labs uses patented resources that help reduce costs. Zinc batteries also can reduce the need to use graphite, which helps reduce their production costs.
“Ultimately, customers care about the same performance, better price or better performance, the same price,” said Srivastava Techcrunch.
Offgrid Energy Labs has also been designed to allow you to improve or not optimize the battery based on the application. This signifies that these zinc batteries can work no matter environmental conditions and ensure energy storage even at temperatures as little as minus 10 degrees Celsius, said Srivastava.
Startup attacks industries with net purposes that want to maximize renewable energy consumption by integration of battery storage. The batteries are also tested for applications corresponding to peak change and decentralized energy solutions outside the network. Shell – who invested in offgrid during the seed round through the corporate arm of the undertaking – and the power of pop belongs to the early testers. The start also takes place with global players, including in Europe, Enel Group, to develop batteries adapted to their specific use cases.
Until now, offgrid Energy Labs has manually built battery technology in DIY Laboratory at NOIDA at Uttar Pradesh. However, the startup plans to use its facility in Great Britain to exhibit its technology to early clients next yr.
Srivastava said that the British facility would have a carbon trail 50% lower than in the case of a typical gigafactory of the lithium battery, adding that the startup decided on simpler production processes to reduce capital and operational costs.
Asked why Great Britain – not India – was chosen for the first facility, Srivastava said that Europe offers a strong ecosystem and is already a battery production center. The startup already has co -founders of Kusurkar and Tulalalalan based in Great Britain, who help in local operations. Despite this, the startup perceives India as one of the key markets when the batteries are ready for commercialization in 2026.
The round A series was led by Archean Chemicals, a producer of specialist chemicals from Chennai, who currently has 21% shares in the startup, along with the participation of Ankur Capital.
Srivastava told Techcrunch that Archean’s participation is a strategic alignment, because the company listed on the stock exchange has significant specialist knowledge in the production of bromals and supply chain management.
The startup is priced at around $ 58 million for money.
