Advancements in Battery Technology
Shirley Meng and an international team of researchers recently demonstrated the ability to control oxygen activity in a lithium-ion battery with the help of a single atom. This new advance at a fundamental level will help to develop better batteries and could bring society one step closer to developing a more efficient and efficient form of energy storage and storage.
Meng does not put his chip into a particular battery, but is exploring the possibility of fully exploiting the mature and novel batteries that could have applications. Lithium-ion, for example, has been the subject of a great deal of research and development in recent years. The big selling point of the flow of batteries is that there will be no degradation within two decades and we should pay for lithium-ion as an energy storage device.
A bill has recently been introduced in the US Congress, which has not yet been voted on, which provides that batteries have the same energy density as lithium-ion batteries, but at a lower cost. Separately, a proposal has been made to build a battery that meets the requirements of the picture below.
As grid batteries become cheaper and cheaper, even tiny car batteries will be needed in the near future due to the need for energy storage.
While lithium-ion batteries are ubiquitous and growing in use cases, it has been difficult to include battery management in determining the end of life. Panasonic has developed a new battery management technology that will greatly simplify this. In collaboration with Professor Masahiro Fukui from Ritsumeikan University and researchers from Japan’s National Institute of Energy Research and Technology (NIST), Panasonic says that their new technology can be used in a battery management system that allows the battery to be monitored and evaluated at different stages of its life, such as when cells are stacked, as could be found in an electric car.
Panasonic claims that this system will help in the quest for sustainability by being able to better control the reuse and recycling of lithium-ion batteries.
In November 2017, Samsung developed a unique graphene ball that could charge lithium-ion batteries longer, more durable and faster. Indeed, the Samsung Advanced Institute of Technology (SAIT) says that the new graphene spherical material used to make the battery will increase its capacity by 45%, making it capable of charging and discharging faster than any other battery available today.
In addition, the Samsung battery, which uses graphene spherical material, will be able to maintain a temperature of 60 degrees Celsius, which is required for use in electric cars, as opposed to the existing limit of 50 degrees. Tesla’s new battery will be based on chemical additives and material coatings that reduce internal stress and allow the battery to store more energy for longer periods, the source said. In November 2016, Huawei unveiled its graphene-enhanced Li-ion battery, which remains functional even at high temperatures. It offers twice the energy density that can be achieved with existing batteries, but at a fraction of the cost.
Tesla is working with its subsidiary Redwood Materials to build another in South Australia in 2017 and another in California in 2018. Tesla also plans to introduce a highly automated battery manufacturing process that will lower labor costs and increase production at its sprawling Nevada factory, a strategy that was telegraphed to analysts and Musk in late April.
Solid batteries are the most promising technology available and are on the verge of mass introduction into electric vehicles. Once they have overcome these hurdles, they are expected to gain a significant share of it in the coming years.
Current lithium batteries require longer charging times to be fully charged, but if they are effective, removing lithium could drastically reduce that number. This will bring us closer to a battery that will be much more efficient than the current lithium-ion batteries in electric vehicles.
Musk wants to buy a product that will revolutionize the driving experience while also giving him big fat profits.
Major car manufacturers are banking on breakthrough technologies that will enable long-range electric vehicles that can travel perhaps 500 miles on a charge, which will finally convince reluctant consumers that they are not running out of energy on the road. Cheaper and better batteries are clearly central to our efforts to decarbonize the economy. They allow us to use renewable energy for all weather conditions, to switch quickly to electric vehicles and to move towards a low-carbon economy with less dependence on fossil fuels.
Toyota Motor Corp., for example, has invested $13.9 billion in its battery business and $1.5 billion in lithium-ion batteries for its Prius electric car. In an interview with Bloomberg in February, he said that this kind of short-term energy storage will not help integrate large amounts of renewable electricity. While the US Department of Energy and the National Renewable Energy Laboratory have already begun feeding lithium-ion batteries into the grid, the plants will only provide electricity for a few hours.
