Batteries

MIT researchers have created a semisolid flow battery that might be able to outperform lithium-ion and vanadium redox flow batteries. It features a new electrode made of dispersed manganese dioxide particles shot through with an electrically conductive additive, carbon black.

As part of their efforts to bring lithium-ion battery degradation under control, scientists in China have looked to emulate natural defenses many organisms have evolved to reduce oxidation reactions and related damage. With an additive that ‘scavenges’ reactive particles before they can contribute to degradation, the group was able to demonstrate significantly lower electrolyte decomposition in a working battery.

The battery features a modular design with pre-integrated segments that contain batteries, thermal management, and safety systems. The design offers scalability and supports up to 200 MWh storage per acre.

Canada-based Elcora said the transaction will enhance its mining operations and energy storage business.

Scientists in the United States pieced together data from hundreds of different sources, looking to establish the key factors that have led to consistently falling prices for lithium-ion technology since their commercialization thirty years ago. They find that public-funded research, primarily in chemistry and materials science, has made the largest contribution to cost reduction. And they offer suggestions on policy and investment to ensure that the research can continue to make these important contributions to reduction in battery costs.

English manufacturer Aceleron claims every component of its devices can be accessed for replacement, repair or recycling, with the business’ co-founder stating the aim is to ensure ‘100% of the materials in our batteries will continue to be used for as long as possible – preferably forever.’

Developed by a spin-off of Dutch research institute TNO, the battery is claimed to offer higher energy density, longer lifespan and increased safety compared to conventional lithium-ion batteries. It will initially be applied in wearables and electric cars.

The Netherlands storage industry association and the Dutch grid operators have proposed a faster phasing out of the net metering scheme to enable wider adoption of batteries among PV system owners. A 30% rebate on the purchase and installation of residential storage systems could help achieve the plan.

BloombergNEF says falling battery costs and “surging” renewables penetration make energy storage a “compelling flexible resource in many power systems.”

The Chinese manufacturer says the battery has a depth of discharge of 95%. It will be available for sale starting from Q1 2022.
