Because lithium-ion batteries are able to store a significant amount of energy in such a small package, charge quickly and last long, they became the battery of choice for new devices. But new battery technologies are being researched and developed to rival lithium-ion batteries in terms of efficiency, cost and sustainability.
To find promising alternatives to lithium batteries, it helps to consider what has made the lithium battery so popular in the first place. Some of the factors that make a good battery are lifespan, power, energy density, safety and affordability.
However, most of the alternative battery technologies considered have a lower energy density than lithium-ion batteries, which is why a larger quantity of raw materials is typically required to achieve the same storage capacity.
As a result of this demand, numerous lithium battery alternatives are in development that could shift the power balance for energy storage 一 given they are feasible, and more importantly, scalable.
Most battery-powered devices, from smartphones and tablets to electric vehicles and energy storage systems, rely on lithium-ion battery technology. Because lithium-ion batteries are able to store a significant amount of energy in such a small package, charge quickly and last long, they became the battery of choice for new devices.
The growing global demand for batteries is currently covered for the largest part by lithium-ion batteries. However, alternative battery technologies are increasingly coming into focus due to geopolitical dependencies and resource availability.

A deep-cycle battery is a battery designed to be regularly deeply discharged using most of its capacity. The term is traditionally mainly used for in the same form factor as ; and contrasted with starter or cranking automotive batteries designed to deliver only a small part of their capacity in a short, high-current burst for starting an engine. A deep-cycle battery will have depth of discharge greater than 50%, and may go as high as 80%. [pdf]
To prevent damage while discharging a lead acid battery, it is essential to adhere to recommended discharge levels, monitor the battery’s temperature, maintain proper connections, and ensure consistent maintenance. Recommended discharge levels: Lead acid batteries should not be discharged below 50% of their total capacity.
Specific actions and conditions can contribute to the premature discharge of a lead acid battery. For example, frequent deep discharges, prolonged storage in a discharged state, or operation in extreme temperatures can exacerbate the sulfation process. Regular maintenance and following guidelines for discharge levels are vital.
By understanding and implementing these practices, users can effectively prevent damage while discharging a lead acid battery and ensure its reliable performance. Discharging a lead acid battery too deeply can reduce its lifespan. For best results, do not go below 50% depth of discharge (DOD).
Personally, I always make sure that anything connected to a lead acid battery is properly fused. The common rule of thumb is that a lead acid battery should not be discharged below 50% of capacity, or ideally not beyond 70% of capacity. This is because lead acid batteries age / wear out faster if you deep discharge them.
It's best to immediately charge a lead acid battery after a (partial) discharge to keep them from quickly deteriorating. A battery that is in a discharged state for a long time (many months) will probably never recover or ever be usable again even if it was new and/or hasn't been used much.
A deep-cycle lead acid battery should be able to maintain a cycle life of more than 1,000 even at DOD over 50%. Figure: Relationship between battery capacity, depth of discharge and cycle life for a shallow-cycle battery. In addition to the DOD, the charging regime also plays an important part in determining battery lifetime.
