Yes, most batteries are recyclable. This however depends on the type of battery. Some of the most common types of batteries that can be recycled and have their materials recovered are:
A battery is a device that holds electrical energy in the form of chemicals. With the help of an electrochemical reaction, it converts stored chemical energy into direct current (DC) electrical energy.
A battery is a device that stores energy and can be used to power electronic devices. Batteries come in many different shapes and sizes, and are made from a variety of materials. The most common type of battery is the lithium-ion battery, which is used in many portable electronic devices.
LFP batteries also contain phosphorus, which is used in food production. If all batteries today were LFP, they would account for nearly 1% of current agricultural phosphorus use by mass, suggesting that conflicting demands for phosphorus may arise in the future as battery demand increases.
As new materials are discovered or the properties of traditional ones improved, however, the typical performance of even older battery systems sometimes increases by large percentages.
Batteries were invented in 1800, but their complex chemical processes are still being studied. Scientists are using new tools to better understand the electrical and chemical processes in batteries to produce a new generation of highly efficient, electrical energy storage. For example, they are developing improved materials for the anodes, cathodes, and electrolytes in batteries.
Reactions are not fully understood. Terminal voltage very stable but suddenly drops to 1.5 volts at 70–80% charge (believed to be due to presence of both argentous and argentic oxide in positive plate; one is consumed first). Has been used in lieu of primary battery (moon buggy). Is being developed once again as a replacement for Li-ion.
If this kind of battery is over-discharged, the reagents can emerge through the cardboard and plastic that form the remainder of the container. The active chemical leakage can then damage or disable the equipment that the batteries power. For this reason, many electronic device manufacturers recommend removing the batteries from devices that will not be used for extended periods of time.

Zinc-air: Several technologies and configurations employ metallic zinc as the battery anode. Zinc-air batteries generate electricity when zinc is oxidized with oxygen from the air. They have a higher energy density than lithium-ion batteries, meaning that they can store more energy in a smaller space. The small batteries used in hearing aids today are typically zinc-air batteries, but they could also be used at larger scales for industrial applications or grid-scale energy storage.
5 volts, the same as the alkaline battery (since both use the same zinc–manganese dioxide combination). A standard dry cell comprises a zinc anode, usually in the form of a cylindrical pot, with a carbon cathode in the form of a central rod. The electrolyte is ammonium chloride in the form of a paste next to the zinc anode. The remaining space between the electrolyte and carbon cathode is taken up by a second paste consisting of ammonium chloride and manganese dioxide, the latter acting as a depolariser. In some designs, the ammonium chloride is replaced by zinc chloride.
Battery life (or lifetime) has two meanings for rechargeable batteries but only one for non-chargeables. It can be used to акумулатори describe the length of time a device can run on a fully charged battery—this is also unambiguously termed "endurance".[55] For a rechargeable battery it may also be used for the number of charge/discharge cycles possible before the cells fail to operate satisfactorily—this is also termed "lifespan".[56] The term shelf life is used to describe how long a battery will retain its performance between manufacture and use.
Batteries consist of two electrical terminals called the cathode and the anode, separated by a chemical material called an electrolyte. To accept and release energy, a battery is coupled to an external circuit.
