电池特点

优点

1．能量比较高。具有高储存能量密度，已达到460-600Wh/kg，是铅酸电池的约6-7倍；

2．使用寿命长，使用寿命可达到6年以上，磷酸亚铁锂为正极的电池1C（100%DOD）充放电，有可以使用10,000次的记录；

3．额定电压高（单体工作电压为3.7V或3.2V），约等于3只镍镉或镍氢充电电池的串联电压，便于组成电池电源组；锂电池可以通过一种新型的锂电池调压器的技术，将电压调至3.0V，以适合小电器的使用。

4．具备高功率承受力，其中电动汽车用的磷酸亚铁锂锂离子电池可以达到15-30C充放电的能力，便于高强度的启动加速；

5．自放电率很低，这是该电池最突出的优越性之一，一般可做到1%/月以下，不到镍氢电池的1/20；

6．重量轻，相同体积下重量约为铅酸产品的1/6-1/5；

7．高低温适应性强，可以在-20℃--60℃的环境下使用，经过工艺上的处理，可以在-45℃环境下使用；

8．绿色环保，不论生产、使用和报废，都不含有、也不产生任何铅、汞、镉等有毒有害重金属元素和物质。

9．生产基本不消耗水，对缺水的我国来说，十分有利。

比能量指的是单位重量或单位体积的能量。比能量用Wh/kg或Wh/L来表示。Wh是能量的单位，W是瓦、h是小时；kg是千克(重量单位)，L是升（体积单位）。

缺点

1．锂原电池均存在安全性差，有发生爆炸的危险。

2．钴酸锂的锂离子电池不能大电流放电，价格昂贵，安全性较差。

3．锂离子电池均需保护线路，防止电池被过充过放电。

4．生产要求条件高，成本高。

5．使用条件有限制，高低温使用危险大。

Battery FeaturesEdit Broadcast

advantage

1. energy is relatively high. It has high storage energy density, which has reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries;

2. Long service life, the service life can reach more than 6 years, the battery with lithium ferrous phosphate as the positive electrode is charged and discharged at 1C (100% DOD), and there is a record of 10,000 times of use;

3. The rated voltage is high (the single working voltage is 3.7V or 3.2V), which is approximately equal to the series voltage of 3 NiCd or NiMH rechargeable batteries, which is convenient to form a battery power pack; the lithium battery can pass a new type of lithium battery voltage regulator technology, the voltage is adjusted to 3.0V, which is suitable for the use of small electrical appliances.

4. With high power tolerance, the lithium iron phosphate lithium-ion battery for electric vehicles can reach 15-30C charge and discharge capacity, which is convenient for high-intensity startup acceleration;

5. The self-discharge rate is very low, which is one of the most prominent advantages of the battery, generally less than 1%/month, less than 1/20 of the nickel-metal hydride battery;

6. Light weight, the weight is about 1/6-1/5 of lead-acid products under the same volume;

7. High and low temperature adaptability, can be used in the environment of -20℃--60℃, and can be used in the environment of -45℃ after technical treatment;

8. Green and environmentally friendly, regardless of production, use and scrap, it does not contain or produce any toxic and harmful heavy metal elements and substances such as lead, mercury, and cadmium.

9. Production basically does not consume water, which is very beneficial to my country, which is short of water.

Specific energy refers to the energy per unit weight or unit volume. Specific energy is expressed in Wh/kg or Wh/L. Wh is the unit of energy, W is watt, h is hour; kg is kilogram (unit of weight), L is liter (unit of volume).

shortcoming

1. Lithium primary batteries have poor safety and there is a danger of explosion.

2. Lithium-ion batteries of lithium cobalt oxide cannot be discharged at large currents, are expensive and have poor safety.

3. Li-ion batteries need to protect the circuit to prevent the battery from being overcharged and overdischarged.

4. The production requirements are high and the cost is high.

5. The use conditions are limited, and the high and low temperature use is dangerous.
