Majorly, batteries are classified in to two types, such as, • Primary Batteries (Non-Rechargeable) • Secondary Batteries (Rechargeable) 𝐏𝐫𝐢𝐦𝐚𝐫𝐲 𝐁𝐚𝐭𝐭𝐞𝐫𝐢𝐞𝐬 Primary batteries are batteries which only can be discharged one time and then discarded. They are designed for one time use only. Below are some types of primary batteries. 1. Zinc-Carbon: Common, low cost, variety of sizes 2. Magnesium (Mg/MnO2): High capacity, long shelf life 3. Mercury (Zn/HgO): Higher capacity, long shelf life 4. Silver/Zinc (Zn/Ag2O): Highest capacity, costly, flat discharge 5. Li/Soluble Cathode: High energy density, wide temp range 6. Li/Solid Cathode: High energy density, low temp performance, long shelf life 7. Li/Solid Electrolyte: Low power, extremely long shelf life Usually, primary batteries are inexpensive, light-weight with low or no maintenance and convenient to use. These batteries often can be found in inside consumer electronic devices such as remote controls, lighting torches, wireless mouses, smoke detectors, garage door openers etc. 𝐒𝐞𝐜𝐨𝐧𝐝𝐚𝐫𝐲 𝐁𝐚𝐭𝐭𝐞𝐫𝐢𝐞𝐬 A secondary battery is also known as Rechargeable Battery since they can be electrically recharged after discharge. The chemical status of the electrochemical cells can be recharged to their original status by applying a reverse current as the electrochemical reaction is reversible. Below mentioned types are the four major secondary battery types. 1.
