Batteries nowadays are one of the most important components of electronic appliances and are used in almost every portable electronic device. From Drones to phones, and tablets to automobile EVs, one common electronic component you find is the battery.
The current battery market reached around USD 113.4 billion. This market keeps increasing with the development of EVs and the expansion of portable electronics and wearable electronic devices.
From a range of devices like Phones to EVS to drones to automobiles, the battery and type also differ and are based on use cases.
So let’s understand the depth of these battery types.
The first main classification of battery is on two types i.e. primary batteries and secondary batteries.
Primary Battery
Primary batteries are non-rechargeable disposable batteries. Once fully drained, primary cells can’t be recharged and you can say it’s a single-cycle battery. They consist of the chemical inside it that gets consumed with time and use and once it’s fully drained, you need to dispose of it.
Types of Primary Battery
Alkaline Batteries:
This type of battery drives the energy by a reaction of zinc metal and manganese oxide and we named it an alkaline battery because instead of using an acidic electrolyte, we use an alkaline electrolyte like potassium hydroxide (KOH).
Advantages:
- More life
- Shelf life is more
- Small in size
- Highly efficient
- Low internal resistance so that discharge state in idle state is less
- Leakage is low
Aluminum-Air Batteries:
This is the highest energy density battery and produces energy from the reaction of oxygen with aluminum. Once the aluminum is consumed and all aluminum gets reacted with air oxygen, we can’t use this battery further and we need to dispose of it after a single use.
Dry Cells:
This is another type of primary battery and most of us use it in our toys and TV remote control but these batteries are now getting replaced by alkaline batteries because of their high lifetime and energy density over the dry cells.
The dry cell is named after its electrolyte type as we use the dry electrolyte in it instead of liquid or wet electrolyte.
There are many other kinds of primary batteries as well but we mostly use mentioned above batteries.
There are the following other kinds of primary batteries or you can say disposable single-cycle batteries.
- Lemon/potato battery
- Lithium battery
- Lithium-air battery

Secondary Battery
These kinds of batteries are multicycle batteries. We can recharge these batteries and use this kind of battery in many cycles of recharge. We mostly use these kinds of batteries in EVs, Phones, Automobiles, Portable gadgets, and in many different areas.
Based on environmental conditions and kind of need and use we further have different types of secondary batteries; some of the most popular secondary batteries that we use in most places are the Li-Ion battery, Li-Polymer Battery, and Lead Acid battery.
Types of Secondary Batteries
Li-Ion Batteries
This kind of battery uses Lithium metal so named Li-Ion battery. These batteries are composed of cells and lithium ions from the negative electrode move to the positive electrode and when we charge, the ions move back to their place; this cycle occurs in each charging and discharging process.
The power density of Li-ion batteries is 126 Wh/Kg.

Li-Po Batteries
The Li-Po battery a.k.a. lithium polymer battery, we named polymer battery because it uses polymer electrolyte instead of liquid electrolyte. The high conductivity gel polymer form of electrolyte is used. These batteries carry high energy density compared to their weight.
These are mostly used in drones due to their lightweight and high density of energy. It has a Power density of 185 Wh/Kg.
Ni-MH Batteries
Ni-MH (nickel metal hydride) battery uses nickel oxide hydroxide and they are quite similar to Nickel cadmium NiCd batteries but here they use a hydrogen-absorbing alloy instead of cadmium and have a lower impact on the environment compared to others.
The power density of these batteries is 100 Wh/Kg.
Lead-acid Batteries
The lead acid battery has electrodes submerged in sulfuric acid electrolytes. These batteries are quite bulky and are mostly used in automobiles, UPS, Grid power stations, etc.
