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...

The biggest difference between a charger and an adapter is that the charger only charges the battery, while the adapter can not only charge the battery but also provide power to the host;The lithium-ion battery charger includes a power adapter function because it has an additional control circuit co...

Power adapters are widely used in routers, telephone consoles, game consoles, language repeaters, walkthroughs, laptops, mobile phones, and other devices. Most power adapters can automatically detect 100-240V AC power (50/60Hz).Power adapters with large space are usually built-in, and the size of th...

A power adapter is a power converter that undergoes voltage transformation, rectification, and stabilization, and outputs DC. It can be understood as a low-voltage stabilized power supply while meeting power requirements. The important function of a power adapter is voltage stabilization, which gene...
