1. High specific energy type electrolyteThe pursuit of high specific energy is currently the biggest research direction for lithium-ion batteries, especially as mobile devices occupy an increasing proportion in people's lives, battery life has become the most critical performance.2. High power e...

Capacity is one of the most important parameters of lithium-ion batteries, and its size varies with temperature.After expert analysis, the temperature limit set for mobile lithium-ion batteries is generally between 40-60 degrees Celsius, and explosion-proof valves are usually marked on the batteries...

Reasons for ignition of power lithium-ion battery packsThe essence of causing a lithium-ion battery pack to catch fire is that the heat inside the battery is not released according to the design intention, causing the ignition point of internal and external combustibles to ignite. The main causes of...

Lithium ion batteriesAdvantages: There is no memory effect (referring to the phenomenon that if the battery is a nickel cadmium battery, if it is not charged or discharged for a long time, it is easy to leave traces inside the battery and reduce the battery capacity. Another explanation is that the...

At present, the energy density of lithium-ion batteries is generally between 200-260wh/g, and lead-acid is generally between 50-70wh/g. Therefore, the weight energy density of lithium-ion batteries is 3-5 times that of lead-acid batteries. This means that under the same capacity, lead-acid batteries...

The types of lithium-ion battery cell explosions can be classified into three types: external short circuit, internal short circuit, and overcharge. The external refers to the external part of the battery cell, including short circuits caused by poor insulation design inside the battery pack.Lithium...

The reasons for the explosion of 18650 lithium-ion batteries1. Internal short circuit: Structural or process defects leading to insertion of the pole ear, insufficient wrapping of the diaphragm, burrs, diaphragm folding, etc. Insertion of pole ears often occurs in structures with thick batteries and...

1. Each individual lithium-ion battery needs to be paired with parameters such as capacity, internal resistance, and voltage. At the same time, the battery cells with inconsistent self discharge should be picked out.2. Reasonably design the shape of the protection board, the charging and discharging...

1. The temperature should not be too highIf UPS batteries are used in environments above the specified operating temperature of 35C, the battery's charge will continuously decrease, meaning the battery's power supply time will not be as long as usual. If the device needs to be charged at suc...

Installation precautions for lithium iron phosphate batteriesBefore installing the lithium iron phosphate battery pack, the open circuit voltage must be measured, and the open circuit voltage difference cannot exceed 50mV. The battery test must be done well and recorded.Although lithium iron phospha...
