What are the new types of batteries that are not far from widespread use?

The two concepts of "widely used" and "not far away" are very vague, and the aspects of application are also relatively general, whether it is used as a mobile terminal battery, or used as a power battery, or a stationary power storage device is not clearly defined, so it is not very good. If it is a secondary battery system, the closest to large-scale application is the all-solid-state battery, the farther is the first-ion battery, and the final pole is the lithium-air battery. Fuel cells have also developed rapidly in the past two years, and many manufacturers have begun to try to commercialize them, but there is still a long way to go before they can be applied on a large scale.

Finally, there is a flow battery, which has also achieved a lot of scientific research results recently, but it is mainly used in stationary large-scale energy storage facilities. I don't know much about supercapacitors to comment on them, but they are currently mainly used as an auxiliary power source for high-power discharge. <>

The new batteries include silicon-based batteries, room-temperature sodium-sulfur batteries, proton batteries, graphite dual-ion batteries, and aluminum-ion batteries.

1. Silicon-based cells

Lithium-ion batteries.

Graphite anodes have traditionally been used, but researchers and companies are now focusing on silicon anodes. The Si dominant anode can bind lithium ions up to 25 times more than graphite ions. However, these batteries have a low electrical conductivity.

Slow diffusion rate and large volume fluctuations during lithiation. These limitations lead to Si crushing and solid electrolytes.

Instability of the intermediate phase.

2. Room temperature sodium-sulfur battery

Due to the physical and chemical properties of Na and Li ions.

Similar, lithium-sulfur batteries.

One of the most promising alternatives is sodium-sulfur batteries. However, the battery needs a high temperature of 300°C for operation. As a promising alternative, low-cost RT-NAS battery systems have generated extensive research interest and can be used in large-scale grid applications with increased safety.

However, due to the complex reactions within the cell, the theoretical capacity of RT-NAS cells is low.

3. Proton battery

Much research effort has been devoted to the production of high-performance proton exchange membrane fuel cells. However, the viability of PEM fuel cells is a challenge due to their high cost, transportation and storage of hydrogen.

4. Graphite dual-ion battery

In recent years, dual-ion batteries using metals other than lithium have sparked interest in large-scale stationary power storage. The research work is to increase the energy density of DIB by increasing the ion content of the electrolyte and the ability of the electrode to store the Donghe charge.

5. Aluminum-ion battery

Aluminum is being studied as a potential alternative to lithium-ion batteries, which contain aluminum, which is abundant, cheap, readily available and inexpensive. From ETH Zurich.

Swiss researchers have proposed two new technologies that are stepping stones to the commercialization of aluminum-based batteries.

With the country's macro-control of new energy vehicles, electric vehicles are becoming more and more popular, and at the same time, people are more concerned about the batteries of electric vehicles, whether they use more advanced lithium batteries or other types of batteries.

<> power batteries of electric vehicles can be divided into secondary batteries (including lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, lithium batteries) and fuel cells. According to the research report of the State Information Center, liquid lithium-ion batteries, lead-acid batteries and nickel-metal hydride batteries are used at this stage. However, due to energy density and power density, it will not be the future development direction.

The future direction is metal-air batteries (possibly lithium), all-solid-state lithium-ion and fuel cells.

At present, there are also calls for hydrogen energy vehicles, and it can be seen that hydrogen energy vehicles will not replace lithium battery vehicles, and they will develop in harmony. However, other batteries have the potential to replace traditional ternary lithium batteries. I have a friend who does this, often communicate together, with his understanding of the industry, the Japanese German system has a disagreement on the battery strategy, the Japanese focus on fuel cells, Toyota is at the forefront, there is already mass production of fuel cell technology, Honda and Nissan are also actively promoting fuel cells (as can be seen from their corporate technical reports, a large introduction to fuel cell technology research), auxiliary all-solid-state batteries.

The German system mainly focuses on metal-air batteries and all-solid-state lithium-ion batteries, supplemented by fuel cells. Volkswagen's electrification strategy clearly states that the all-electric driving range is more than 600 km and the charging time is 5 minutes, which is difficult to solve by relying on lithium-ion batteries.

In my personal opinion, hydrogen energy will not become the mainstream of mobile transportation, but there must be a market. According to Toyota's internal technical report, even by 2050, hydrogen energy will only account for 5% of Toyota's market, and there is no large-scale hydrogen energy plan in Germany at present, so it is difficult to say what proportion of the total amount will be in the world. Therefore, even Toyota, which is at the forefront of hydrogen energy, does not think that fuel cells will become the mainstream, but should pay attention to whether there will be new power batteries to replace lithium-ion batteries.

Now the batteries of electric vehicles are all relatively advanced lithium batteries, which charge quickly, have large capacity, and are relatively safe to charge.

Yes, and in this case, the car will travel farther, and it can also improve people's quality of life, and the cost performance is relatively high.

Lithium batteries can be broadly divided into two categories: lithium metal batteries and lithium-ion batteries.

Lithium metal batteries generally use manganese dioxide as the cathode material, lithium metal or its alloy metal as the anode material, and use non-aqueous electrolyte solution.

The fifth-generation product of rechargeable batteries, lithium metal batteries, was born in 1996, and its safety, specific capacity, self-discharge rate and performance** ratio are better than those of lithium-ion batteries.

Lithium-ion batteries are generally batteries that use lithium alloy metal oxide as the cathode material, graphite as the anode material, and non-aqueous electrolyte.

Lithium-ion batteries do not contain metallic lithium batteries and are rechargeable. Both mobile phones and laptops use lithium-ion batteries.

There are several reasons why producing better quality power batteries for Rubber can promote people's participation**

1.Improve the value: If the power battery is more durable and high-quality, then even after a certain service life, their quality can still maintain a high level, which brings higher value to the battery.

The production of better and more durable power batteries such as lead-led power batteries can improve the value of the product and motivate people to participate.

2.Reducing environmental pollution: It is an important part of the circular economy, and if people are more actively involved, the environmental impact of discarded batteries can be reduced.

At the same time, in the production of better and more durable power batteries, more environmentally friendly and sustainable materials and production processes can be used, so as to reduce environmental pollution in the battery manufacturing process.

3.Sense of responsibility: With the increasing global environmental awareness, more and more consumers and enterprises are willing to take on certain environmental responsibilities.

By producing higher-quality, durable, and obsolete power batteries, companies can demonstrate their concern and sense of responsibility to the public about environmental issues, thereby enhancing people's awareness of environmental protection and responsibility, and promoting more people to participate**.

Therefore, the production of better and more durable power batteries can bring more value and significance, motivate people to participate more actively in the process, and promote the development of the entire battery industry in a more environmentally friendly and sustainable direction.

At present, as long as it is not converted into electrical energy, it is called a battery.

For example, solar cells, fuel cells, chemical cells.

The purpose is to generate electricity.

There are many kinds of chemical energy batteries, there are disposable ones (such as dry batteries), and there are rechargeable ones, such as storage batteries, some of which have high battery voltage, and some have low voltage. For example, general dry batteries, lithium batteries are currently commonly used in alkaline batteries, nickel-metal hydride batteries, lithium batteries, lead-acid batteries, etc., lithium batteries are divided into iron lithium, lithium-ion batteries, lithium poly, etc., there are many types.

According to the appearance, it is divided into button batteries, cylindrical batteries, and prismatic batteries

All in all, a lot.

Dry batteries are used in flashlights, small radios, remote controls for electrical appliances, etc. Lithium batteries, mobile phones, cameras, laptops, etc. Batteries, used in electric vehicles, automobiles, etc.

Optical power battery Intelligent green battery Micro solid polymer fuel cell Organic radical battery New lithium-ion battery Nano power battery 1 Zinc-silver battery.

Zinc-silver batteries, commonly known as silver-zinc batteries, use potassium hydroxide or sodium hydroxide as the electrolyte, silver as the cathode material, and zinc as the anode material. The active material on the positive electrode, which is made of silver, is porous silver, and the active material on the negative electrode, which is made of zinc, is mainly zinc oxide. After being charged with an electrolyte, the silver in the positive electrode becomes bivalent silver oxide, and the zinc oxide in the negative electrode becomes zinc.

Zinc-silver batteries are generally packed in plastic shells or aluminum alloy and stainless steel shells.

The main advantage of zinc-silver battery is high specific energy, its energy-to-mass ratio (effective electrical energy generated per unit mass) reaches 100w·h kg and 130w·h kg (3 4 times that of lead-acid batteries). Zinc-silver batteries suitable for high-current discharge are used in military, aviation, mobile communication equipment, electronic instruments, artificial satellites, aerospace and other aspects. Zinc-silver batteries made into miniature button cells are used in electronic watches, hearing aids, computers, and pacemakers.

2 Lithium batteries.

Lithium is the lightest metallic element in nature. With lithium as the negative electrode and matching with the appropriate positive electrode, an energy-to-mass ratio of up to 380 w·h kg and 450 w·h kg can be obtained.

Batteries with lithium as the negative electrode are called lithium batteries. As a primary battery, one is a lithium battery with lithium perchlorate as the electrolyte and polyfluorocarbon as the cathode material, and the other is a lithium battery with lithium bromide as the electrolyte and sulfur dioxide as the cathode material.

The main advantages of lithium batteries are that they can emit large electrical energy (much greater specific energy than zinc-silver batteries) in a small volume or weight, the voltage is very stable when discharged, the storage life is long, and they can work effectively in a wide range of temperatures. The application is the same as for zinc-silver batteries. Judging from the development trend, the competitiveness of lithium batteries will exceed that of zinc-silver batteries.

3 Solar cells.

Solar cells commonly used today are made of silicon; Generally, a thin layer of boron is infiltrated into a small piece of electronic-type monocrystalline silicon by diffusion method to obtain a p-n junction, and then an electrode is added. When sunlight hits a thin layer of boron-permeated water, an electromotive force is generated between the poles. Such batteries can be used as a power source for instruments on artificial satellites.

In addition to silicon, gallium arsenide is also a good material for making solar cells.

4 Atomic batteries.

According to reports in 1975, the first atomic batteries were being tested abroad at that time. The 20-watt, 1,398-kilogram atomic battery has sunk to the bottom of the North Sea to supply power to a nearby oceanographic measuring station.

The battery is sealed in a cylinder with a length of 84 cm, a diameter of 69 cm, and a lead outer wall thickness of 10 cm. Its core part is strontium-90. When strontium decays, it produces the equivalent of 300w of heat energy, which is then converted into electricity through a thermoelectric generator.

The final output power is 20W and the voltage is 28V. It is claimed that the atomic battery is maintenance-free and can be used for at least 5 years, and is estimated to last for 10 years.
