What are the types of power batteries?

Types of power batteries include: 1. Ternary lithium-ion batteries; 2. Lithium iron phosphate batteries; 3. Lithium titanate batteries; 4. Lead-acid batteries. Battery maintenance methods are: 1. Avoid overusing the battery; 2. Regularly clean the positive and negative terminals of the battery; 3. Periodically check the vent holes on non-maintenance-free battery covers to prevent clogging; 4. Avoid excessively low battery water levels; 5. When parking for extended periods, start the vehicle once a week to charge the battery. The functions of the battery are: 1. Providing a strong starting current to the starter when starting the engine; 2. Assisting the alternator in supplying power to electrical devices when the alternator is overloaded; 3. Supplying power to electrical devices when the engine is idling; 4. Protecting the vehicle's electrical appliances; 5. Converting some electrical energy into chemical energy for storage when the alternator's voltage is higher than the electromotive force of the lead-acid battery.
As an automotive technology enthusiast, I believe there are several main types of power batteries: the most mainstream are lithium-ion batteries, which are divided into lithium iron phosphate and nickel-cobalt-manganese versions. The former has lower costs and better safety, while the latter offers higher energy density for longer range. There are also nickel-metal hydride batteries, commonly found in hybrid vehicles, which are reliable and durable but slightly less efficient. Lead-acid batteries are used in some older cars or auxiliary systems—they are cheap but bulky and power-hungry. Emerging technologies include solid-state batteries, currently under testing, which offer higher safety and faster charging. I think the core of the technology lies in energy density and lifespan. Lithium batteries currently dominate the market, but temperature management must be considered, as overheating can affect performance. The future trend is integrating material innovations, such as reducing reliance on rare metals and improving recycling rates, which is crucial for the entire EV industry chain. I find researching these topics quite interesting, and car buyers should pay attention to detailed specifications when choosing a vehicle.
