1. What are the use of sports gloves

1. increase the grip of the palm

The material of the sports gloves can help increase the friction between the palm and the fitness equipment, and can hold the dumbbells or barbells more stable, especially for the effect of push -pull movements (such as rising bodies or durlering, etc.).Some gloves also have a strap connected to the wrist, which is used as a handle that rolls the equipment, saving a lot of power.

2. Diversify stress to protect the wrist

When performing a movement of extension (such as premium pushing or referring to the shoulder), the exercise gloves can scatter the weight of the equipment a little, reducing the pressure caused by the opponent's palm.Some gloves also include wrist cares, helping to support the body with both hands such as upper palm pressure or flat plate.

4. Beautiful and beautiful: Beginners generally think that wearing gloves is a professional fitness.

one,Portable energy storage power supplyIndustry status

Portable energy storage products are a built -in high -energy density battery that provides a power system that provides stable AC/DC voltage output. It has the advantages of safe and portable, simple operation, noise, large capacity, high power, and wide adaptability.The upstream of the portable energy storage industry is a variety of raw materials, including battery cells, inverters, electronic components, and various structural components. The middle reaches are manufactured with portable energy storage, and the downstream is the application of portable energy storage, including outdoor activities, emergency emergency, emergency, emergency, emergency, emergency, emergency, emergency, emergency, emergency, emergency, emergency, emergency, emergency, emergency, emergency, and emergency.Electricity and other fields.

At present, the main downstream applications of portable energy storage products have two directions, one is outdoor activities, and the other is emergency power generation.Among them, outdoor activities include Outdoor tourism, Camping, fishing, etc. The audience are quite large, especially in developed countries, the penetration rate of outdoor activities is quite high.With the prosperity of the entire Outdoor market market in the future, as an indispensable thing for outdoor activities, portable energy storage products will naturally have a vast development space.

The energy storage industry is still in the early stages of development in my country. Although there is no policy system and price mechanism related to energy storage related to energy storage at this stage, as an emerging industry, energy storage has become increasingly attracted to the attention and support of government energy departments and science and technology departments. EssenceThe state's development plan for the energy storage industry is gradually being established, and fiscal subsidies for application demonstrations are gradually advancing.Although there are still many problems to be resolved, with the support of government policy, with the joint efforts of energy storage manufacturers, power systems, and relevant scientific research institutes, China's energy storage industry will continue to develop continuously.

The main production place of global portable energy storage is in China, accounting for more than 90%of the output and shipments.But in the future, as the industry competitors will become more, the market share may fluctuate.

The "New Five -Year Plan" New Energy storage Development Implementation Plan "pointed out that under the premise of security and reliability, it is set up a number of mobile or fixed -type new energy storage as an emergency spare power supply around important power users such as the government, hospitals, and data centers.In the case, the centralized calling mechanism of energy storage facilities including electric vehicles, and improve the system's emergency power supply guarantee capabilities.

In the context of increasingly competitive global competition, the national macro level has formulated positive strategic policies to encourage outstanding industry national brands to move towards the global market and establish a strong and excellent independent brand image.In addition, the state has introduced favorable policies in terms of industrial policy, providing a micro -level policy support for improving the market competitiveness of overseas markets of private enterprises in the portable energy storage industry and the globalization of outstanding national brands.The standards and guidance of the national favorable policies and regulations on the industry have pointed out the direction for the development of the portable energy storage industry, which has important and far -reaching significance for the improvement of energy storage technology, and has become a strong driving force for the rapid development of the portable energy storage industry.

two,Energy storage powerMarket prospect

With the rapid development of the global new energy industry, lithium batteries are the most widely used chemical secondary batteries. In recent years, technology has continued to improve. With its cost -effectiveness continuously increased, other secondary batteries such as lead acid have been gradually replaced.The first choice for energy storage batteries.Dispute by the new energy vehicle and energy storage industry, the production capacity of domestic power and energy storage battery enterprises has accelerated production capacity, and the expansion of scale advantages further reduces the price of lithium -ion batteries. In addition, the technology of lithium iron phosphate and sodium ion batteries has maturedThe cost of battery, so the price of portable energy storage products with lithium battery as the main composition is expected to be further reduced. The replacement advantage of traditional small fuel generators will be more obvious, and the penetration rate in the overall market will also increase rapidly.It is estimated that by 2026, the penetration rate of global portable energy storage market will reach 14.5%.

As the scale of the mobile electronic product market continues to expand, the demand for portable energy storage products has gradually increased.At the same time, benefited from the rapid development of the lithium -ion battery market in recent years, and the technical and safety performance of portable energy storage products has gradually improved, becoming one of the indispensable products in daily life.At present, the global portable energy storage product shipments, market scale, output, sales, etc. have maintained a high -speed growth trend, and China has become the main producing area of global portable energy storage products.The United States is the main consumer market for global energy storage products.Although the global portable energy storage battery market is currently hot, most markets still have not been developed. In the future, the global portable energy storage battery market is expected to continue to maintain a high growth rate.
