As smartphones become more and more popular, battery bottlenecks become incredibly tricky! The rapid development of electronic technology has not brought about the development of battery technology, battery technology has been lagging behind for decades! To this day, batteries still play an indispensable role in phones and tablets. Batteries are also known as "batteries" because they can store a lot of electrical energy! In the future, we will enter a fully charged world. Smartphones, drones and electric cars all use lithium batteries. But lithium batteries also have great disadvantages - small storage, frequent charging, short life! These shortcomings greatly limit the development of electronic products and electric vehicles!
Next, the author bypasses the traditional lithium battery and introduces several new battery technologies! Maybe you have some idea of batteries. But it is not necessarily known what role it plays in the automotive field? Maybe you don't know much about fuel cells. But we all know that. Fuel cells are one of the important driving forces for the development of the automotive industry. Maybe there will be some battery technology dominating in the future!
Lithium-air batteries
Lithium air refers to the use of oxygen as an oxidant, not a material. It could reduce battery prices to one-fifth of existing lithium-ion batteries and enable phones and cars to last up to five times the life of existing lithium-ion batteries. I believe that with the development of lithium-air battery technology, it will definitely enter the lives of our ordinary people! However, will the emergence of lithium-air batteries replace lithium batteries as quickly as lithium batteries? What challenges will it face in the future? Are there any problems that need to be solved? These are all questions that need to be answered. Perhaps like lithium batteries, lithium-air batteries still have 5-10 years to become a reality.

Plant batteries
The pot is called BIOO, which uses the energy generated by water and plant photosynthesis to charge devices, tablets, and phones. Fortunately, plant batteries are already on the market. Bioo can charge electronics 2-3 times a day! The standard voltage is 3.5V, the current is 0.5A, and there is also an innovative rock-shaped USB interface. If you want to have more fun in the city, you might transplant this technology into the city. This device will be the infrastructure for the smart cities of the future. Cities will no longer rely on traditional fossil fuels such as oil to survive. This is just the beginning, imagining the whole forest powering us in such a way. Cities can not only achieve 100% green energy, but also protect vegetation!

Gold nanowire battery
Nanowires are a thousand times thinner than human hair, and the volume alone saves a lot of battery space. But they always collapse when charging. Fortunately, the researchers avoided this problem by encapsulating gold nanowires in a manganese oxide shell and placing them in an electrolyte, and then in 200,000 charge-discharge cycles, the battery did not fail, marking a breakthrough in battery technology. The battery of the future will live forever and will not be bad to use! It sounds like a science fiction story, but is that really the case? We know that nanotechnology is a great invention that is changing the way humans live. It will bring a new industrial revolution! That's the new energy revolution! Gold nanowire batteries could be the ideal source of energy for electric cars, spacecraft and mobile phones!
Graphene batteries for automobiles
Graphene batteries will be a major trend in the future. Graphene is considered one of the best lithium-ion secondary battery materials due to its excellent properties. However, the current technology can not fully meet the requirements of electric vehicle development in terms of power performance and cost. Therefore, new batteries need to be developed. A company called Grabat has developed a new graphene battery that can provide an electric car with a range of 500 miles.
The researchers say the battery can be fully charged in minutes and charged and discharged 33 times faster than lithium ions. The discharge speed is the key to the start of the car, if the discharge speed is too slow, the battery can not release a lot of energy to the engine in a short period of time. Therefore, we need a fast, safe and efficient way to charge the battery and the performance of the vehicle. A new type of lithium-ion battery pack is now on the market that is capable of achieving this goal. At 2.3v, Grabat's high energy ratio is about 1000Wh/kg, while lithium ion's high energy ratio is 180Wh/kg.
Skin rubbing the battery
Researchers have developed a device that uses human skin friction to charge electronic devices. Just tap the skin with your hand to charge 12 small LED bulbs. The new technology will allow electronic devices to move no longer as bulky electronics, but as a small , soft and elastic "body generator, the results of which were published in the Proceedings of the National Academy of Sciences." The results of this research could lead to a revolution. This means that future wearables and smart clothes will no longer require built-in batteries.
It works like this: the electrode collects the current and uses a 50 nm gold film. On the contact surface there is a very thin layer of silicon film, the thickness of which is 1 to 2 μm. When the current flows, these silicon films release a lot of heat and heat it up. The energy is then transferred to the body's epidermal cells. The gold film is located underneath a layer of silicone rubber, which is made up of thousands of tiny columns, which helps to increase the surface area of effective skin friction, creating greater friction. Because the large skin is a triboelectric layer, this means that the device can be very small.
Nano batteries
Nano batteries are 80,000 times smaller than human hair, store 3 times more power than existing lithium batteries, and most critically, it can be charged and discharged thousands of times in 12 minutes. Nano-batteries are a new type of battery system that uses nanomaterials (such as nanotubes, nanowires and nanorods) as electrode materials to improve the conductivity of lithium ions, thereby achieving rapid charging or discharging functions. The key to nano-cells is tiny "nanopores", which, like many small cells, make up a giant honeycomb-like battery.

Sodium-ion batteries
Japanese scientists have been working on sodium-ion batteries, which are one of the most common substances on Earth, but lithium is scarce, which means batteries can be made with lower raw materials, and people don't have to worry too much about sodium depletion! But sodium-ion batteries have many advantages: high energy density; good safety; long cycle life; low manufacturing costs; pollution-free. Therefore, sodium-ion batteries will become the most competitive products in the next generation of energy. The most critical thing is that sodium ion batteries are 7 times more efficient than conventional battery batteries! Experts expect that sodium-ion batteries will be commercialized in the next 51,010 years!

Ryden dual-carbon battery
Japan's company OzerJapanPlus announced a new battery technology technology - Ryden double carbon. Not only does the battery life be longer than that of lithium batteries, but the charging speed is also 20 times faster than that of lithium batteries! It has a relatively long service life and can last up to 3,000 charging cycles, and dual-carbon batteries are safer and less likely to explode. This battery can complete the charging process in 2 hours, instead of taking 3 days to fully charge the battery. In addition, due to the use of double carbon hydrogen material, double carbon batteries do not produce any harmful substances. What is the reason for this? Dual-carbon batteries use carbon materials to protect the environment.
PowerJapanPlus said it will soon start production of the 18650 Ryden battery. These batteries are designed for cars and are a very small battery, much smaller than the regular batteries used today, but it is still able to meet the demand for lithium-ion powered batteries in future electric and hybrid vehicles. Looking forward to seeing it on the market soon!
