Scientists at the United States Pacific Northwest National Laboratory have discovered a root cause of dendrite formation, which can cause battery failure and even fires in lithium-ion technology. With this new knowledge, the group is now working on electrolyte recipes that eliminate dendrite growth entirely.
The aim is development of sustainable, integrated solutions for both short- and long-term storage. November 12 is the last date for submitting expressions of interest. Projects are expected to start before December 15, 2020.
Scientists led by the Technical University of Denmark have begun a project to design solar cells that can be produced in different colors with minimal effect on performance, making them suitable for building-integrated and other applications with aesthetic considerations.
A total of 168 expressions of interest were received by the Ministry of New and Renewable Energy in the second round of PACEsetter Fund programme. Out of these, projects by the Society for Economic and Social Studies, Customized Energy Solutions India, The Energy & Resources Institute and Raghavendra Suntech Systems were chosen for the award of grants.
The invention converts energy produced by PV cells directly into mechanical motion without batteries or power electronics. Its developers claim the solar motor can drive irrigation water pumps and ventilation turbines for more than 20 years without maintenance.
Pilot-scale operations at a facility near Mumbai successfully recycled the spent Li-ion batteries. The company seeks to eventually scale up the capacity to recycle 500 tonnes of spent Li-ion batteries.
A new method of creating an ordered mesh of nanowires, developed by scientists at the Lawrence Livermore National Laboratory in the United States, could lead to the creation of more efficient transparent electrode layers in solar cells – and the elimination of a rare material from the manufacturing process.
