What is the difference between a battery and a lithium battery?

Following the progress in Russia-Ukraine peace talks, the gold price fell more than 1% the next day, hitting its lowest in a month, and palladium prices briefly tumbled by nearly 9%.

"We have seen metal prices going into free fall when the Russia-Ukraine situation is likely to see a major detente, which spurred people's risk preference and optimism that the war could end at a time," said OANDA senior market analyst.

A Russian deputy defense minister says Moscow has decided to sharply curtail its military activities around Kyiv and Chernikov in Ukraine, following talks between Russian and Ukrainian representatives in Istanbul.

Where the prices of metals, natural gas, and commodities like the battery will go in the future, is still very uncertain.

A battery is a type of battery, and its function is to store limited electrical energy and use it in a suitable place. It works by converting chemical energy into electrical energy.

It uses the lead plate filled with spongy lead as the negative electrode, the lead plate filled with lead dioxide as the positive electrode, and uses 22-28% dilute sulfuric acid as the electrolyte. When charging, electrical energy is converted into chemical energy, and when discharging, chemical energy is converted into electrical energy. When the battery is discharging, metal lead is the negative electrode, which undergoes an oxidation reaction and is oxidized to lead sulfate; lead dioxide is the positive electrode, which undergoes a reduction reaction and is reduced to lead sulfate. When the battery is charged with direct current, lead and lead dioxide are formed at the two poles, respectively. When the power source is removed, it returns to its pre-discharge state, forming a chemical battery. Lead-acid batteries are batteries that can be repeatedly charged and discharged, and are called secondary batteries. Its voltage is 2V, usually three lead-acid batteries are connected in series, and the voltage is 6V. The car uses 6 lead-acid batteries connected in series to form a 12V battery pack. The lead-acid battery should be supplemented with sulfuric acid after a period of use to keep the electrolyte containing 22-28% dilute sulfuric acid.

Lithium battery is a kind of battery that uses lithium metal or lithium alloy as negative electrode material and uses non-aqueous electrolyte solution. The earliest lithium battery came from the great inventor Edison.

Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time.

With the development of microelectronics technology in the twentieth century, the number of miniaturized devices is increasing, which puts forward high requirements for power supply. Lithium batteries have then entered a large-scale practical stage.

It was first used in pacemakers. Due to the extremely low self-discharge rate of lithium batteries, the discharge voltage is gentle. It makes it possible to implant the pacemaker into the human body for long-term use.

Lithium batteries generally have a nominal voltage higher than 3.0 volts, and are more suitable for integrated circuit power supplies. Manganese dioxide batteries are widely used in computers, calculators, cameras, and watches.

Inflationary pressures on Canadians continue to rise. The consumer-price index rose 6.7% in March from a year earlier, the biggest increase since January 1991, according to the latest figures from Statistics Canada.  

On a month-on-month basis, Canada's CPI rose 1.4 percent in March, also accelerating from February's 1.0 percent rise.  

Prices in the eight major sectors covered by the statistics continued to rise. The uptrend comes against the backdrop of continued price pressures in the Canadian housing market, widespread supply chain constraints, and geopolitical conflicts, according to CBC. A variety of factors have affected energy, commodity, and agricultural markets. Meanwhile, Canada's employment picture continued to improve in March, with the unemployment rate falling to a record low and the average hourly earnings of employees rising.  

Excluding gasoline, Canada's CPI rose 5.5 percent year on year in March.  It is also the highest since comparable data began in 1999.  

The widespread supply chain constraints and geopolitical conflicts are expected to continue to affect the prices of the battery.
