Cascade utilization and dismantling recycling are important ways to recycle decommissioned lithium-ion batteries.

Lithium-ion battery thermal runaway process, is the thermal runaway reaction of different lithium batteries the same? At present, the safety problem of the automotive power battery system is the safety of the battery group. The automobile power battery acci...

In the lithium-ion battery energy storage system, the temperature sensitivity of the lithium-ion battery mainly stems from the temperature sensitivity of its material physicochemical properties. The temperature will directly affect the activity and conductiv...

Lithium-ion batteries are divided into wound lithium-ion batteries and laminated lithium-ion batteries due to different processing methods. Their principles are different and their performance is the same. So what is the difference between the lithium-ion b...

Whether or not the end user is satisfied with the design of their portable device largely depends on the performance of the battery....

The parameter describing the energy storage size of lithium-ion batteries (hereinafter referred to as lithium batteries) is energy density, which is approximately equivalent to the product of voltage and lithium battery capacity. method to achieve the goal. H...

The charging pile is fixed on the ground, uses a special charging interface, and adopts the conduction method to provide AC power for electric vehicles with on-board chargers, and has corresponding communication, billing and safety protection functions. Ci...

Even if the capacity is not enough, the unit price is low, the cycle is good, and the safety is high, no one cares about the battery produced. So how can we improve the energy density of the battery?...

The battery pack usually refers to the packaging, packaging and assembly, and the operation process of the assembled battery. Since the lithium battery forms a certain voltage and capacity according to the series-parallel circuit of the single lithium batter...

When people buy a car, they usually install some extra accessories on their car. For example, install some small objects with personality outside and inside the car, or install some more practical things in the car, such as a driving recorder....

For the automatic start-stop function, many drivers and friends know that it needs to be turned off on rainy days, otherwise it will easily cause the vehicle to stall during wading. However, there is one part that is very important for automatic start and st...

Lithium batteries are composed of positive electrode material, negative electrode material, electrolyte and other parts. Among them, the negative electrode material directly affects the energy density of the battery, and its importance to the battery is self...

According to reports, the discharge capacity of lithium-ion batteries at -20°C is only about 31.5% of that at room temperature. The operating temperature of traditional lithium-ion batteries is between -20 and +60°C. However, in the fields of aerospace,...
