Lithium battery explosion-proof technology

Lithium battery explosion-proof technology

Lithium-ion batteries have become the batteries of portable electronics. This kind of battery has high capacity density and competitive price, and is expected to remain the mainstream of the market in the next few years. But lithium batteries have always hidden the danger of explosion. Due to the wider and wider application, explosion incidents also emerge in an endless stream. In fact, lithium-ion batteries can be made very safe through correct battery system design and battery level determination. At present, the explosion-proof circuit and explosion-proof battery technology are mature, and explosion incidents should be less and less.

What are the differences between lithium batteries and lead-acid batteries

There are many types of lithium batteries at present, and different lithium batteries have different functions. For example, the batteries we often see include lithium batteries, lead-acid batteries, 18650 lithium batteries, etc. The differences between different batteries are also various, so what should we do? to identify them. Today, let's take a look at the difference between lithium batteries and lead-acid batteries.

Why does lithium battery charge more temperature than discharge

The battery products of many companies can achieve normal discharge at low temperature, but at the same temperature, it is difficult to achieve normal charging, or even unable to charge. When Li+ is embedded in graphite material, it must first be solvated. This process will consume a certain amount of energy. Li+ is hindered from diffusing into the interior of graphite; on the contrary, Li+ will have a solvation process when the graphite material is released into the solution, and solvation does not consume energy, and Li+ can quickly come out of graphite. Therefore, the charge acceptance of graphite materials is significantly inferior to the discharge acceptance.

Innovation drives the sustainable development of the new energy industry. Guanjia Lithium Battery keeps its mission in mind and sticks to its original intention

Under the electrification transformation of the global energy industry, the rapid development of the lithium battery industry has set off a global storm of lithium batteries. Statistics show that the global lithium battery market segments have maintained rapid growth. For example, the shipment of lithium batteries for light vehicles will reach 9.7GWh in 2020, a year-on-year increase of 78%; 124%. China's lithium battery companies have ushered in an opportunity for comprehensive development. But at the same time, the lithium battery industry is characterized by capital-intensive, talent-intensive, technology-intensive, and high-quality risks, which is an industry threshold that is difficult to cross. On the other side of opportunities are challenges and risks: investment encirclement and blind expansion lead to overcapacity structure; attack from all sides while ignoring business management and deep cultivation of market segments; blindly pursuing a single data indicator, ignoring comprehensive technical requirements; ignoring quality , quickly gain the market with low-price competition, and seek short-term benefits. All of these may become hidden reefs under the changing situation of the industry.
