Maintenance-free batteries have the characteristics of low price, easy portability, and large capacity, and have been used in emergency lights, flashlights, UPS power supplies, motorcycles, electric bicycles, and electric tricycles. However, if it is used improperly, it will cause damage to the batt...

With rising energy prices and stricter global emissions standards, demand for renewable energy sources such as solar and wind power, as well as energy storage solutions, will continue to rise. The large amount of thermal energy of the sun makes it an attractive energy source. This energy can be dire...

The battery electrolyte allows electric charges to pass the battery plates between the two terminals. The electrolyte brings the chemicals needed for the reaction into contact with the anode and cathode, thus converting the stored energy into usable electricity. The electrolyte acts as a catalyst, m...

The failure of lead-acid batteries may be caused by a variety of reasons, such as vulcanization, water loss, thermal runaway, active material shedding, plate softening, etc. Next, we will introduce and analyze them one by one. 1. Vulcanization The process of charging and discharging lead-acid batter...

There are many reasons why batteries fail prematurely. The main failure reasons of a lead acid battery are listed below. 1. Internal short circuit. The battery-plates are the key to battery service life, and the chemical reactions required for the battery to work slowly corrode them. It&nb...

As an emergency backup power source, the stability of the battery is the key core to maintain critical power supply when any emergency requires. But the battery will also face retirement, generally in the following three situations, you may need to replace the battery. 1. Internal swelling/inflation...

Graphene is a new material in which carbon atoms linked by sp² hybridization are closely packed into a single-layer two-dimensional honeycomb lattice structure. It has optical, electrical and mechanical properties and is widely used in materials science, micro-Nano processing, energy power...

Emergency lighting is wired to the buildings’ power supply for continuous charging of internal batteries to provide back up power for the lighting.  This ensures that lights remain alight during a power outage allowing occupants to easily locate the exits should they need to evacuate the buildi...
