Союзроссахар: сбоев в поставках сахара и его дефицита нет

Представители объединений производителей продуктов заявили об отсутствии дефицита подсолнечного масла или сахара в России. Об этом сообщает РИА «Новости».

По словам исполнительного директора Масложирового союза России Михаила Мальцева, о дефиците не может быть и речи, поскольку объем производства масла в два раза превышает объем внутреннего потребления.

А председатель правления Союза сахаропроизводителей России Андрей Бодин добавил, что на рынке сахара ситуация остается стабильной и сбоев в его поставках в России нет.

Ранее Минсельхоз, Минпромторг, производители, а также поставщики продовольственных товаров и крупнейшие торговые сети подписали документ, устанавливающий предельные цены на сахар и подсолнечное масло.

До этого «Ъ» сообщал, что у некоторых торговых сетей в России возникли сложности с закупкой подсолнечного масла и сахара по фиксированным ценам.

Ризван Магомедов, менеджер действующего обладателя чемпионата пояса Абсолютного бойцовского чемпионата (UFC) в легком дивизионе Хабиба Нурмагомедова, подвел итоги встречи с главой промоушена Даной Уайтом. Об этом сообщает «СЭ».

По его мнению, 32-летний дагестанец сумел подтвердить звание неоспоримого авторитета своей весовой категории.

«Ну тут все предельно ясно. Понятно, кто является Боссом легкого дивизиона, так пусть стараются привлечь его внимание, чтобы ему захотелось вернуться.

Только им придется очень сильно постараться», — сказал Магомедов.

Ранее сообщалось, что тренер Хабиба Нурмагомедова Хавьер Мендес высказался о возможном возвращении бойца в октагон.

For many electric car drivers, the biggest anxiety while on the road is the fear of running out of charge.

But the days of spending hours at a charging station could soon be a thing of the past, thanks to a new electric car battery that reaches full charge in just five minutes.

The lithium-ion battery can power the car for up to 100 miles on a single charge, and could be available from 2025.

Its designers say the battery marks a significant step towards electric cars becoming as fast and easy to 'refuel' as petrol or diesel vehicles.

The battery was developed by Israeli company StoreDot, who have already demonstrated their fast-charging batteries in smartphones, drones and scooters.

Now the start-up is turning its attention to electric cars.

Speaking to The Guardian, Doron Myersdorf, CEO of StoreDot, explained: 'The number one barrier to the adoption of electric vehicles is no longer cost, it is range anxiety.

'You're either afraid that you're going to get stuck on the highway or you're going to need to sit in a charging station for two hours. But if the experience of the driver is exactly like fuelling [a petrol car], this whole anxiety goes away.

'A five-minute charging lithium-ion battery was considered to be impossible. But we are not releasing a lab prototype, we are releasing engineering samples from a mass production line. This demonstrates it is feasible and it's commercially ready.'

Most lithium-ion batteries use graphite as one electrode, pushing the lithium ions through to store charge.

However, these ions can get congested if pushed through too rapidly, limiting the rate at which you can charge your car.

To combat this issue, the StoreDot battery uses semiconductor nanoparticles, into which ions can pass much more easily.

These nanoparticles are currently based on germanium, although StoreDot hopes to start using silicon.

Speaking to Intelligent Transport, Mr Myersdorf said: 'Replacing graphite with metalloids, such as silicon, is a very serious and important transition in battery technology, and it's designed to do one of two things: either improve energy density or leverage the capability of ion diffusion to improve charging times.'

Unfortunately, silicon-based batteries are currently more expensive to produce than lithium-ion batteries.

Mr Myersdorf added: 'Silicon is cheap and very readily available – it's second in abundance only to oxygen on Earth.

'What's difficult is that there still isn't a high-quality supply chain for silicon for batteries, because we need it to be pure and consistent, and we need the particles in it to be a certain size and shape.

'For example, if we are using 500 nanometres of silicon, the cost for that is higher just because there is no supply chain in place.'

When the StoreDot batteries first go on sale in 2025, this could mean they're around 10-15 per cent more expensive than lithium-ion alternatives.

However, Mr Myersdorf is optimistic that these costs could be cut over time as the company scales.

'Over time as we scale, we should hit the same costs and the same cost curve reduction as we've seen with today's EV batteries, because the supply chain should improve,' he added.

StoreDot isn't the only firm working on super-fast charging electric car batteries.

Earlier this week, researchers from Penn State University revealed that they are developing an electric car battery that charges in just 10 minutes and lasts for 250 miles on a single charge.

The EV batteries are made from lithium iron phosphate, which is known for its 'unsurpassed safety', and can quickly heat up and cool down – key to rapid charging and a long life.

They quickly heat up to 140°F for charge and discharge and then cool down when the battery is not being used.

The system could tackle 'range anxiety' – drivers' fears that they don't have sufficient charge on their electric vehicle (EV) to get them to their destination.

Researchers say their battery should last more that 2 million miles in a lifetime and would be 'a well-rounded powertrain for mass-market EVs' if commercialised.

Chao-Yang Wang, who led the study, said: 'We developed a pretty clever battery for mass-market electric vehicles with cost parity with combustion engine vehicles.

'This is how we are going to change the environment and not contribute to just the luxury cars. Let everyone afford electric vehicles.'
