Lithium batteries are sensitive to overcharging and undercharging, so it is essential to choose a compatible charger to avoid any potential damage. In addition, different types of lithium batteries may have different charging requirements. For example, lithium-ion and lithium-polymer batteries may require different chargers due to their different chemistries.
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer

Lithium dendrites growth has become a big challenge for lithium batteries since it was discovered in 1972. 40 In 1973, Fenton et al studied the correlation between the ionic conductivity and the lithium dendrite growth. 494 Later, in 1978, Armand discovered PEs that have been considered to suppress lithium dendrites growth. 40, 495, 496 The latest study by
Battery degradation is a collection of events that leads to loss of performance over time, impairing the ability of the battery to store charge and deliver power. It is a successive and complex set of dynamic chemical and physical processes, slowly reducing the amount of mobile lithium ions or charge carriers.
The battery generates power when lithium ions move from the anode to the cathode, which creates a flow of electric current. When the battery is recharged, the process happens in reverse, with lithium ions moving from the cathode back to the anode. This process is destructive. So,
State of Charge In lithium-ion batteries, battery degradation due to SOC is the result of keeping the battery at a certain charge level for lengthy periods of time, either high or low. This causes the general health of battery to gradually deteriorate.
Both modes of lithium loss reduce the charge “currency” or lithium inventory, and thus the battery’s capacity, because there will be a diminished amount of lithium freely available to convey charge between the positive and negative electrodes.
The degradation of lithium-ion battery can be mainly seen in the anode and the cathode. In the anode, the formation of a solid electrolyte interphase (SEI) increases the impendence which degrades the battery capacity.
The lithium ions end up getting trapped within the microscopic structure of the electrodes, and that makes it so fewer ions can participate in the next charge cycle. Over a long period of time, a significant amount of ions become permanently trapped, which reduces the battery's overall capacity and increases its resistance.
Calendar Aging: Even when not in use, lithium-ion batteries undergo a process called calendar aging. The passage of time, along with temperature and storage conditions, can cause chemical reactions within the battery that degrade its performance.
