What are the advantages and disadvantages of​ lithium batteries?

Commodity prices are on track for their biggest rally in more than a century, while fixed-income assets have seen their longest run of outflows as the war in Ukraine adds to inflationary pressures in the global economy emerging from the coronavirus lockdown, according to Bank of America.

“Commodity prices this year are on track to record their biggest gains since 1915.” the bank said in its weekly briefing. They cite many factors, such as pandemics, lockdown, civil strife, wars, excessive monetary and fiscal stimulus, and supply chain disruptions, that have led to “historically” high inflation.  

By the same token, it said government bonds were heading for their worst year since 1949, and “negative-yielding bonds will quietly disappear” from the market as central banks embark on a monetary tightening cycle and raise interest rates to tame soaring inflation.  

The prices of many commodities like the lithium batteries are expected to increase in the future.

The advantages of lithium batteries

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).

The shortcoming of lithium batteries 

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.

The development of the Russia-Ukraine conflict will continue to dominate the commodity prices such as the lithium batteries in the future. If the conflict eases or cools, Russia and Ukraine go back to negotiate, commodity prices would fall. However, if the situation between Russia and Ukraine deteriorates further, or evolves into a full-scale war, the price of the lithium batteries is predicted to see further improvement over the coming days.
