Due to the high energy density of  Lithium Batteries , it's difficult to ensure the protection of batteries. After the battery is overcharged, the electricity will probably be excessive when the temperature rises, so the electrolyte will decompose and produce gasoline, which will get the threat of spontaneous combustion or rupture due to the increasing of internal pressure; otherwise, under the overdischarge illness, the electrolyte will hamper the battery characteristics and durability due to decomposition, thus reducing the amount of charges. The security circuit of lithium-ion battery is to ensure the security of over-charging and discharging, and to stop the deterioration of characteristics. The security circuit of lithium-ion batteries is composed of a protection IC and two power MOSFETs, where the protection IC monitors the voltage of the batteries, switches into a power MOSFET hanging out when discharging and interrogate, and protects the batteries. The function of the pr

Over the last two decades, the  Lithium Iron Phosphate Battery  has caused a transformation from the consumption of metals and minerals. The landscape is expected to change further as the Li-ion battery evolves from mobile applications, such as the mobile phone with a small 10 watt-hours (Wh) pack, to the electrical car with a battery capacity of 50--100kWh, and to the monster Electronic Storage System (ESS) with up to 10MWh battery banks. At the start of the millennium, only a small percentage of both cobalt and lithium moved to batteries, but by 2015 46 percent of cobalt and 32 percentage of lithium went into Li-ion production. Graphite, nickel manganese, copper and aluminum have yet to be affected in precisely the same way.

Battery entrepreneurs and users often ask,"Can batteries be revived?" A battery failure doesn't always imply end of battery life. Rather than shedding a pack, innovative entrepreneurs are finding business models to give retired batteries a second lifetime. Considering the growing amount of batteries which are being discarded, such business opportunities can only increase. The three main battery defects are low ability, high internal resistance and elevated self-discharge. Capacity fade occurs naturally with use and time; resistance growth is common using nickel-based batteries; and elevated self-discharge reflects possible pressures endured within the field. Capacity loss may frequently be reversed with NiCd and NiMH; lead acid with sulfation can sometimes also be made better. (See BU-901: Basics in Battery Testing.) Capacity fade happens naturally with time and use; resistance growth is common using nickel-based batteries; and elevated self-discharge reflects stress.

As  Lithium Battery Pack Supplier , today we brief introduce some knowledge of explosion-proof technology of batteries. Lithium is the smallest and most active metal on the chemical periodic table. Because of its small size and high capacity density, it is widely welcomed by consumers and engineers. However, if the chemical properties are too lively, the risk is very high. When lithium metal is exposed to air, it will react with oxygen and explode. To improve safety and voltage, scientists have invented materials such as graphite and lithium cobalt to store lithium atoms. The molecular structure of these materials forms tiny nanoscale storage lattices that can be used to store lithium atoms. In this way, even if the battery shell breaks down and the oxygen enters, it can not get into these tiny cells because of the oxygen molecules too large, so that the lithium atoms do not contact with oxygen to avoid the explosion. This principle of  Lithium Batteries  enables people to obtain hi

Explore the oldest kinds of batteries along with the coming of power. Among the most remarkable and novel discoveries within the past 400 years has been power. We may ask,"Has power been about that long?" The solution is yes, and possibly more. Its practical usage has just been at our disposal because the mid to late 1800s, and in a limited manner in the beginning. A number of the first public functions gaining focus were roads lighting in Berlin in 1882, light up the Chicago World's Fair in 1893 with 250,000 light bulbs, also hammering a bridge across the river Seine throughout the Paris 1900 World Fair. The usage of power may go back farther. While building a railroad in 1936 near Baghdad, employees uncovered what seemed like a prehistoric battery, also referred to as the Parthian Battery. The battery consisted of a clay jar which was full of a vinegar solution into that an iron pole surrounded by a copper pipe was inserted. This apparatus produced 1.1 to 2.0 volts of

After the  E-bike Batteries  used for a period of time, a lot of consumers find that the electric car battery is getting worse and worse. It can't run for a long time. What's the matter? As  E-bike Battery Supplier , today we will explian the reason. 1. in the process of battery charging and discharging, the phenomenon of "sulphidation" will affect the battery capacity. Vulcanization means that the battery is gradually covered by the hard lead sulfate crystallization during the use of the battery, resulting in the gradual reduction of the area of the active plate and the decrease of the concentration of the acid, which reduces the capacity of the battery. 2. The battery charging voltage of electric vehicles in 2. winter and summer is different, such as no suitable charger which can adjust with the environment pressure, which will cause the overcharge of the battery to cause the battery to lose the water and eventually cause the battery to drum, deform, or decreas

E-bike Batteries  for electric bikes, such as fish can not open water is generally important, now people want to replace batteries for electric bikes, the choice may be a variety of options. How can I buy a reassuring E-bike battery? In order to buy electric car batteries, it is necessary to take into account the distance of its continued mileage, the length of the service life, and the stability of the safety performance. Citizens can go to the official website of the Internet to understand the battery information of their own electric vehicles. If they need more detailed information, they can also call a consulting phone or know by QQ or WeChat. It can also be consulted and purchased by  E-bike Battery Supplier  and manufacturer.
