Haryana-based Sanvaru is expanding its lithium battery production capacity to 400 MWh per year by setting up a new factory in Haridwar.

The US Consumer Product Safety Commission and Health Canada have issued a joint recall of patio umbrellas due to fires caused by the overheating of lithium-ion batteries.

State-run power producer NTPC has launched global bidding to supply 135 MWdc of 530 Wp crystalline solar modules for its Anta solar project in Baran district, Rajasthan. Bidding closes on July 28.

French researchers have developed PV modules with an area of 11.6 square centimeters for indoor applications. They said the achieved efficiency level marks a world record for a flexible perovskite device larger than 10 square centimeters.

Researchers from the Indian Institute of Science, Bangalore, have found that nanoscopic refractory metal layers like tungsten could improve dendrite growth tolerance in electrolytes of solid-state Li-ion batteries. The team collaborated with researchers from Carnegie Mellon University.

Vikrant Singh, co-founder and CTO of BatX Energies, told pv magazine that the company would use the funds to scale up its capacity, with plans to launch material production from end-of-life lithium batteries on a commercial scale. It will also set up recycling units in different geographies to locally produce black mass – a mixture of battery anode and cathode materials – and ship it to its India facility for battery material extraction.

A research team in Hong Kong has built a solar window that can generate power on the external side via a luminescent solar concentrator and thermal energy on the internal side via transparent solar absorbers.

Rajasthan-headquartered Natural Battery Technologies has developed lithium-based inverter batteries that can be charged with solar power. The batteries are designed for residential and commercial use, with storage capacities typically ranging from 1.5 kWh to 20 kWh. The company can offer other sizes, too, according to customer requirements.

A new report shows that renewable energy companies will continue to compete in upcoming auctions in India, undeterred by challenges such as rising materials costs and surging interest rates.

Tongwei has also secured another massive polysilicon order and Golden Glass has invested in more heterojunction solar cell capacity. Furthermore, China’s National Energy Administration (NEA) said 23.7 GW of new solar was deployed in China in the first five months of the year.
