1. Lithium cobaltate
(1) Features: small size, light weight; no memory effect; long cycle life (more than 1000 times); high temperature resistance (up to 300 ° C or more); cheap price, etc. (2) Application field:
digital Products such as mobile phones, digital cameras and other power management chips; charging control circuit boards and chargers in electric tools
(3) Disadvantages: low energy density
2. Lithium manganate
(1) Features: high energy density
(2) Application areas: power management modules and chargers for notebook computers; power battery packs for automobiles (for starting the engine) and power battery packs for electric bicycles (for driving the motor), etc... Lithium manganese oxide The capacity is larger, but the price is relatively high! At present, the common notebook power management modules for notebooks on the market use lithium manganese oxide batteries as energy storage devices!
3. Ni-MH battery
(1) Features: High specific energy
(2) Advantages: Good safety
(3) Disadvantages: High cost
4. Lithium iron phosphate battery
(1) Features
Lithium iron phosphate battery has a high energy density. Because its electrode active material is phosphate, it is called lithium iron phosphate battery or iron-phosphorus-aluminum secondary alkaline battery. It has the following main advantages: (1) no memory effect; (2) self-discharge Small; (3) wide operating temperature range; (4) long service life; (5) fast charging and discharging with high current; (6) good environmental protection. (7) Good economy. (8) Good safety performance. (9) Good shock resistance. (10) Excellent low temperature performance.
(2) Application fields
Lead-acid maintenance-free batteries are the most widely used in the electric vehicle industry. This kind of battery has a relatively long service life and low cost and is suitable for mass production. However, due to the limited storage capacity of lead-acid and easy leakage Therefore, the state has banned the use of lead-acid storage equipment.
Most of the electric vehicle market now uses a new type of maintenance-free battery, that is, a new type of zinc-silver alloy battery. The advantage of this type of battery is that it has a strong storage capacity, is not easy to leak, does not pollute the environment, and can be reused. The production cost improves the economic benefit.
