Are Nickel-metal hydride batteries about to withdraw from the historical stage?

For the entire HEV market, data provided by foreign research institutions show that in 2012, the total sales volume of global HEVs was 1,152,200, including 433,100 in the US, 836,600 in Japan, 140,500 in Europe, and 115,100 in other regions. The HEV market consumes a total of 1.692 million kWh of secondary batteries, of which 1.585million kWh of nickel-hydrogen batteries, accounting for 93.68%; and 107,000 kWh of lithium-ion batteries, accounting for 6.32%.

 

The agency expects global HEV sales to reach 2.5 million units by 2015, 5 million units by 2020, and 7 million units by 2025. The United States and Japan are always the two largest markets for HEV, and the global share of sales will remain above 73%. On the secondary battery used, the agency believes that the proportion of lithium-ion batteries will increase at a faster rate. The agency expects that the number of nickel-hydrogen batteries in the HEV field will reach 2.097 million kWh by 2015, accounting for 85.24%; the lithium-ion battery will be 363,000 kWh, accounting for 14.76%. By 2020, the use of nickel-hydrogen batteries will reach 3.146 million kWh, accounting for 65%; lithium-ion batteries will be 1.694 million kWh, accounting for 35%. By 2022, the amount of nickel-metal hydride batteries and lithium-ion batteries will be half, both of which is 2.059 million kWh. After that, the amount of nickel-hydrogen battery on HEV will drop rapidly, and will drop to 533,000 kWh by 1025, accounting for 10%; while the consumption of lithium-ion battery is up to 4.794 million kWh, accounting for 90%, basically completing the nickel-hydrogen battery replacement process.

 

It is an indisputable fact that nickel-metal hydride batteries are not far behind, no matter how much you want to stay and try to reduce the losses caused by previous investments!

 

The nickel-hydrogen battery, which was widely used in the field of mobile communication, will gradually withdraw from the historical stage. This kind of ruthlessness is evident from the rapid replacement process of nickel-metal hydride by the mobile phone industry. In the 1990s, mainland China began to use mobile phones for more than 20 years. In the field of mobile phones, lithium batteries have completely replaced nickel-metal hydride batteries. This is a market change brought about by technological progress, and no one can fight and escape.

 

Today, nickel-metal hydride batteries are still alive in some narrow areas, the hybrid vehicle industry and some energy storage areas. However, due to the backwardness and limitations of technology, nickel-metal hydride batteries are bulky and have low energy density. The market environment is deteriorating day by day, and the market share is narrowing day by day.

 

We recall that behind the decline of film industry leader Kodak is the rise of digital technology. It is inevitable that nickel-metal hydride batteries will withdraw from the historical stage. What is left now is time. We can even more pessimistically predict that nickel-metal hydride batteries will disappear completely from the market within five years as lithium technology advances and costs continue to fall.
