With manufacturing ramping up year by year and policies already looking to get ahead of the large volumes of end-of-life products, the landscape for lithium-ion battery recycling is rapidly changing. pv magazine recently spoke with Mari Lundström, associate professor of chemical and metallurgical engineering at Aalto University, to find out what is needed on the research side for the effective recycling of batteries.

The Swiss group has acquired an integrated solar roof system solution from an unidentified German engineering service provider for this purpose. The aim is grow this sector from a niche market.

A British-Australian research team has assessed the potential of liquid air energy storage (LAES) for large scale application. The scientists estimate that these systems may currently be built at a cost between €300 and €600 (AU$480 to $960) per megawatt-hour and that a positive business case could be favoured by certain conditions, including a determined price structure in the energy market and the presence of a grid unable to support high levels of renewable energy penetration.

The manufacturer has launched sodium-ion products online. Production has begun and will be easily scalable, according to the CATL chairman. Researchers have been keen to make the technology work as it offers a cheaper, more environmentally friendly alternative to lithium-ion products.

Polluting energy sources received more than $3 trillion from the EU and 19 of the world’s largest national economies over that four-year period, despite G20 members having pledged to phase-out fossil fuel subsidy and address climate change back in 2009.

Potential price rises of 14% for the solar home systems that are driving access to electricity in the world’s under-served regions could signal further arrested progress towards the UN goal of universal access by 2030.

The latest global PV industry outlook published by trade group SolarPower Europe, has indicated tight supply of the solar panel raw material is expected to persist this year but the trade body said it would be unlikely to drive further price rises.

The manufacturer plans to start production of the performance-enhanced solar modules in August. The first customers should then receive the products in October.

Recent research has revealed a previously underestimated role for oxygen in limiting the performance of lithium-ion batteries. Newly published research from both Japan and the United States has sought to look deeper into the chemical reactions at the heart of lithium-ion storage; and to better characterise the cumulative effects that minuscule amounts of oxygen released during these reactions can have on battery performance and safety.

European commissioner for economy Paolo Gentiloni has outlined how the commission’s planned revision of the energy taxation regime, and introduction of an EU carbon border, could be applied.
