Major Development From Nissan Can Boost EV Battery Life, Extend Driving Range

As car batteries are continually charged and depleted, overall battery capacities begin to diminish, eventually leading to battery replacement. It remains one of the many issues affecting electric vehicles, however, Japanese carmaker Nissan Motor Company believes they may have found the solution by using silicon.

Nissan has reached a major breakthrough with its new lithium ion battery generation, which will significantly extend the driving range of zero-emission electric vehicles. The breakthrough was the result of combined research and development efforts between Nissan subsidiary Nissan Arc Ltd., Tohoku University, the National Institute for Materials Science (NIMS), the Japan Synchrotron Radiation Research Institute (JASRI) and the Japan Science and Technology Agency (JST).

Nissan is launching research into the use and structure of amorphous silicon monoxide (SiO) as an alternative to traditional carbon-based materials, currently used in lithium batteries. This breakthrough has allowed researchers to better understand electrode structure during charging cycles and prove SiO’s resistance to the deterioration which occurs during repeated charges.

The structure of amorphous SiO is still relatively unknown; merely that it can typically hold much more lithium than standard battery materials. By holding more lithium ions, battery capacity will rise, leading to better performance for electric vehicles.

Last Friday marked the announcement by Nissan that its researchers have developed the new analysis method that has cracked the SiO’s base structure code. The discovery has confirmed that SiO is able to store a greater number of lithium ions than previously believed. Mass production is nevertheless difficult to forecast at present until further information is known.

Senior Vice President of Nissan Motor Co., Ltd. and President of Nissan Arc Ltd, Takeo Asami, said that the next generation of high-capacity lithium ion batteries is entirely dependent on current analyses. “It will certainly become one of our core technologies,” he said in a statement. “The utilization of this analysis method in our future R&D will surely contribute to extending the cruising range of future zero-emission vehicles.”

Daniele Schillaci, Executive Vice President of Nissan Motor Co., Ltd., said the development represents an added proof point of Nissan’s commitment to innovation in advanced technologies. “Nissan is exploring a wide range of energy sources for tomorrow’s vehicles, and we recognize our role in continuously investing in multiple technologies and intelligent mobility.”

Corporate Sourcing of Renewables Growing, Taking Place in 75 Countries

Companies in 75 countries actively sourced 465 terawatt hours (TWh) of renewable energy in 2017, an amount close to the overall electricity demand of France, according to the report from the International Renewable Energy Agency (IRENA). With the continued decline in the costs of renewables, the report suggests, corporate demand will continue to increase as companies seek to reduce electricity bills, hedge against future price spikes and address sustainability concerns.

Wind: China Maintains Emerging Markets Top Spot Following 19.7GW Build Boom

Wind industry intelligence service A Word About Wind has launched its Emerging Markets Attractiveness Index report for 2018, which provides insight and analysis into the most attractive emerging markets for wind companies. The index, now in its second year, ranks the top 30 emerging markets that investors should consider when investing in wind in Europe, Africa, Asia and Latin America. The list considers factors including political and economic stability for investors, alongside the growth of electricity demand and potential for wind growth, in order to rank the countries by overall potential. As with last year’s report, China tops the list and the ongoing trade war with the US shows no sign of slowing China’s formidable growth.

EU Approves Ambitious Energy Efficiency Goals, Encourages Clean Energy Feed-In

Europeans will now be entitled to consume, store and sell the renewable energy they produce in line with ambitious targets set by the EU. The targets are to be reviewed by 2023, and can only be raised, not lowered. By making energy more efficient, Europeans will see their energy bills reduced. In addition, Europe will reduce its reliance on external suppliers of oil and gas, improve local air quality and protect the climate. For the first time, member states will also be obliged to establish specific energy efficiency measures to the benefit of those affected by energy poverty. Member states must also ensure that citizens are entitled to generate renewable energy for their own consumption, to store it and to sell excess production.
