Spain-based battery manufacturer and importer and exporter, CEMA Baterías, is urging motorists

Batteries using Silicon Joule bipolar technology, pioneered by US-based company Gridtential Energy, are expected to hit the market for the first time during this year. CEO John Barton tells World Battery News about the company's achievements to date – and the exciting opportunities that lie ahead...

The completion by US lead-acid battery recycler Aqua Metals of its V1.25L electrolyser programme marks the latest step forward for the company as it heads into 2021. According to Aqua Metals, the programme has been completed "on time and under budget” – and achieving lead production that is 100% greater, compared to the V1.0 electrolyser deployed at its Nevada AquaRefinery during commercial production in 2018 and 2019.

Nissan has unveiled a 100% electric emergency response vehicle concept, designed to provide a mobile power supply following natural disasters or extreme weather. The RE-LEAF working prototype is based on the Nissan LEAF passenger car, the world's first mass-production electric car. Alongside modifications to navigate roads covered in debris, the RE-LEAF features weatherproof plug sockets mounted directly to the exterior of the vehicle, which enable 110- to 230-volt devices to be powered from the car's high-capacity lithium-ion battery. The RE-LEAF can be driven into the centre of a disaster zone and provide a fully mobile power supply to aid the recovery process. The integrated energy management system can run medical, communications, lighting, heating and other life-supporting equipment. 'Greater resilience' Helen Perry, head of electric passenger cars and infrastructure for Nissan in Europe, said: "Concepts like the RE-LEAF show the possible application of EVs in disaster management and demonstrate that smarter, cleaner technology can help save lives and provide greater resilience.” Nissan EVs can also act as mobile storage batteries to supply homes and society with electricity during non-emergency situations through Nissan Energy Share, creating a distributable energy model that can be used to help stabilise supply and demand. The RE-LEAF uses the LEAF's bidirectional charging ability, a standard feature of the model since its introduction in 2010. This means the LEAF can not only "pull” power to recharge the high-capacity battery, but also "push” it back to the grid through V2G (vehicle-to-grid) technology, or directly to electric devices through V2X (vehicle-to-everything).

The new 'EASy Marine' certified lithium iron phosphate (LFP) battery system from EAS Batteries, part of the Monbat Group, allows hybrid propulsion at the highest safety level. This unique battery system for efficient fuel consumption in shipping adapts flexibly to limited space conditions, increases safety on the water and reduces emissions and solves three problems of inland and deep-sea shipping worldwide. Michael Deutmeyer, MD of EAS Batteries, christened the mechanical modular battery concept for the maritime industry to mark its completed DNV-GL certification. This was done in the virtual presence of the management of the Monbat Group at EAS’ production site in Nordhausen, Germany – and the system was released for serial production. Monbat COO Peter Bozadjiev said the innovation represented "future-proofed vision". He said: "We have invested in extraordinary technology for a future worth living – in the safety of people on the water and in the protection of our environment by reducing emissions.” "With the support of the Monbat Group, EAS Batteries has succeeded in developing a modular marine battery system that enables almost every ship owner to achieve these goals on a daily basis.” Bozadjiev said: "EAS Batteries has designed EASy Marine in record time and successfully launched it on the market. The trust we have placed in our subsidiary, EAS Batteries, has thus been more than confirmed. We are very proud and congratulate them on attaining the DNV-GL certificate!” Flexible topology – the battery fits on board The modular space concept of the battery system enables almost every ship owner to convert their propulsion system to a fuel-optimised hybrid system. This is because the battery design can be adapted to almost any type of ship architecture. EAS head of sales, Dr Frank Diehl, said: "This is like Lego for adults. The modules can be flexibly combined. Rigid battery racks, some more than two metres high, are now a thing of the past. With the EASy-Marine Modules, it is possible to reproduce steps, so that even sloping walls no longer present a space problem." Up to 1,500V can be connected in series – 50% more than usual – and LFP means safe cell chemistry on the water. The cell chemistry of EASy-Marine modules is based on LFP, which is considered to be extremely safe. The battery can become hot in the event of a short circuit, overcharging or mechanical damage to the cell, but it does not burn. "Burning Li batteries cannot be extinguished – only cooled," Diehl said. "EASy Marine rules out such a drama on the open sea from the outset." High performance, environmentally-friendly propulsion "EASy Marine is robust and extremely powerful,” Deutmeyer added. "It is particularly suitable for hybrid applications, since it can release and absorb energy very quickly." The goal of hybrid systems, which combine batteries with diesel generators, for example, is to keep fuel consumption in the so-called "sweet spot" – therefore at the optimum level – throughout. The result is the minimum use of fuel and thus the lowest possible emission of CO2 and other emissions. With EASy Marine, diesel savings can amount to up to 30% per ship. Other energy sources, such as a fuel cell for hydrogen propulsion, can also be operated highly efficiently with EASy Marine. EAS Batteries – innovative technology from Germany EASy Marine is a product with a future, Deutmeyer added. "The maritime market is increasingly developing towards hybrid electromobility – albeit somewhat more slowly in the new reality. And because of its advanced features, especially its safety, EASy Marine is a true and long-awaited blessing for the maritime industry." It is the first flexible standard product that the German battery manufacturer, EAS Batteries, has developed itself, on the basis of its own cells and which it has now brought to market. EASy Marine can be used in the entire maritime industry for hybridisation or as a fully-electric component, for example in gantry cranes or offshore installations.
