1. Wet Cell Battery Definition : A wet cell battery contains a liquid electrolyte (usually sulfuric acid) that facilitates the flow of electricity. Examples : Lead-acid car batteries, marine batteries. Advantages : Can supply high current Rechargeable (in the case of lead-acid batteries) Disadvantages : Requires maintenance (checking and refilling electrolyte) Can leak or spill if not handled properly 2. Dry Cell Battery Definition : A dry cell battery contains a paste-like electrolyte , making it spill-proof and more portable. Examples : AA, AAA, C, D, and 9V alkaline batteries. Advantages : Compact and portable Leak-resistant compared to wet cell batteries No need for maintenance Disadvantages : Usually non-rechargeable (except some NiMH and NiCd versions) Lower energy storage compared to rechargeable battery types 3. Lithium Battery Definition : A lithium battery uses lithium metal as the anode and is usually non-rechargeable . Examples : Button cell batteries (used in watches, calculators), some camera batteries. Advantages : Long shelf life Lightweight High energy density (more power in a small size) Disadvantages : Expensive compared to alkaline batteries Not rechargeable 4. Lithium-Ion (Li-Ion) Battery Definition : A rechargeable battery that uses lithium ions moving between the cathode and anode to store and release energy. Examples : Smartphone batteries, laptop batteries, power banks, electric vehicle batteries. Advantages : Rechargeable and long-lasting High energy density (stores more power than other types of rechargeable batteries) Lightweight compared to lead-acid batteries Disadvantages : Can degrade over time (loses capacity after many charge cycles) Expensive compared to traditional rechargeable batteries Risk of overheating or catching fire if damaged Conclusion: Wet cell : Liquid electrolyte, used in cars and heavy-duty applications. Dry cell : Paste electrolyte, used in household batteries (AA, AAA, 9V). Lithium : Lightweight, long-lasting, but non-rechargeable. Lithium-Ion : Rechargeable, high energy density, used in modern electronics.
