What are the type of skinny batteries called? 

There are plenty of skinny batteries available in the market today. These batteries are no doubt a work of brilliance as they can easily fit even the smallest of gadgets and keep them running. Some of the skinny batteries that are most commonly used in various gadgets include, 

AA Batteries 

The double-A batteries are the most commonly available. These are widely used in many gadgets from thermometers to cordless phones. These batteries are a good choice for devices that require a precisely large current output but are not used frequently. The other gadgets like electric shavers and clocks are also the best use of these batteries. 

Typical Capacity: 600-1500 mAh

Normal Voltage: 1.2 volts 

Size: 1.40 x 40.0 mm 

Low Temperature High Energy Density Rugged Laptop Polymer Battery Battery specification: 11.1V 7800mAh -40℃ 0.2C discharge capacity ≥80% Dustproof, resistance to dropping, anti - corrosion, anti - electromagnetic interference

AAA Batteries

The triple-A batteries are another commonly used skinny batteries, available at every store. These batteries generate a small amount of energy because of their skinny size. They are best for use in small devices that do not require much energy. They can easily be used in various household gadgets like kitchen timers, small toys, and calculators. 

Typical Capacity: 1200, 540, 800-1000 mAh 

Normal Voltage: 1.5 volts 

Size: 10.5 x 44.5 mm 

AAAA Batteries

AAAA Batteries 

The quadruple-A batteries are not common but they are the skinny bombs. They are widely used in many gadgets like laser pointers, glucometers, remote controls, and flashlights. Despite their skinny size, their effectiveness is quite amazing.  

Typical Capacity: 625 mAh 

Normal Voltage: 1.5 volts 

Size: 8.3 x 42.5 mm

CR2032 Batteries

AAAA Batteries 

CR2032 batteries are the most unique and most powerful batteries in skinny size. Its rounded contour and skinny nature make it the best among all. They have a very high weight-to-power ratio that compliments the long-lasting power supply of the battery. These batteries are widely used in wristwatches, thermometers, and other medical appliances. 

Typical Capacity: 225, 190 mAh 

Normal Voltage: 0.2, 0.03 volts 

Size: 20 x 3.2 mm 

Ultra-thin lipo battery 

The Ultra-thin lipo battery is a special type of lithium polymer battery. Its ultra-thin feature makes it unique and smart. This battery is now gaining immense popularity among smartphone companies. Instead of the liquid lithium electrolyte, the battery contains solid polymer electrolytes such as polyacrylonitrile and polyethylene oxide. 

This battery is specifically designed for the thinnest gadgets. It fits the mini card phones, bank cards, information cards, smart cards, mini phones, etc. So, if you are looking for a battery that fits your thin gadgets and provide a suitable power with a longer duration then ultra-thin lipo is the most suitable option for you.  

Features:

Normal Voltage: 3.7-3.8 volts 

Charging Voltage: 4.2 volts

Discharging cutoff voltage: 3.0-2.17 volts

Charging cutoff voltage: 4.2 volts

Flexible foil type polymer case

PCM: Protection circuit required

Capacity: custom

Thickness: 0.4-1.5 mm

Environmentally safe and friendly 

Thin Film Battery 

The thin-film battery is a type of solid-state battery. This battery combines the special features of skinny batteries and the high-efficiency rate of solid-state batteries. This battery reduces the manufacturing cost as the components used are available at cheap prices. Cathode is a thin film of classic lithium-ions. Deposited as metal oxide by various methods including Pulse laser deposition, magnetron sputtering, sol-gel processing, chemical vapor deposition. All these processes ensure the better working of the battery. Moreover, it improves the specific energy, power density, and energy density. 

This battery plays its role in various medical implantation devices like pacemakers and defibrillators. In such uses, it provides a steady and reliable power source that has a long life span. Furthermore, these batteries are widely used in wireless sensors, smart cards, and various energy storing devices. 

Features:

Lighter weight 

Solid polymer electrolyte that acts as a binder, electrolyte as well as a separator. 

High energy density (3x) 

Longer cycling life: 1200 cycles without degradation 

High average voltage output 

Wide temperature range: -20 to 60 degree Celcius 

Button battery size 

The button batteries or watch batteries are single-celled. Their sizes range from 5 to 25 mm wide and 1 to 6 mm high. These batteries have a stainless steel body that resembles a button. This steel body acts as an anode and the top insulated cap acts as a cathode for the battery. The common anode materials used are zinc or lithium. While the cathode materials include manganese dioxide, oxygen, cupric oxide, carbon monofluoride, etc. 

These button batteries are used widely in small portable devices like wristwatches, pocket calculators, hearing aids, remote controls, mini toys, etc. These button cells are mostly primary batteries and are disposable. The most commonly used button batteries are the CR2032 type.
