lead-acid batteries

As the global North ponders e-mobility dilemmas such as how to source sufficient materials to meet electric car demand, fresh evidence has emerged of how solar can decarbonize transport and farming in Africa.

Manufacturer Sunlight plans to invest €30 million to add 1.3 GWh of annual production capacity of lead-acid products by the third quarter of next year. The company will also devote €20 million to expanding its lithium-ion battery assembly lines.

An international research team has conducted a techno-economical comparison between lithium-ion and lead-acid batteries for stationary energy storage and has found the former has a lower LCOE and net present cost. Through their analysis, which was performed assuming the use of the batteries in connection with a 10 kW, grid-tied PV system, the scientists concluded that lithium-ion batteries are the most viable solution.

BloombergNEF and Sustainable Energy for All have jointly published a report by the Mini-Grid Partnership proposing solar minigrids as a critical technology to bring electricity to the 789 million people who still lack access.

Researchers from China are proposing to use spent battery lead for creating a perovskite that can be used in the production of solar cells that are based on this promising material. The proposed one-step process, which was tested in the production of a 17.38% efficient perovskite heterojunction cell, is said to be cheaper and less energy-intensive than other recycling processes for waste lead from lead-acid batteries.

With concerns over the mountains of PV system waste that will one day pile up around the world, Bangladesh is no exception – the nation currently has no solar panel recycling policy.
