Lithium Battery VS Alkaline Battery

- Dec 04, 2018 -

The introduction of electric vehicles and the need for energy storage devices will enable lithium-ion batteries and solid-state alkaline rechargeable batteries to compete in the years and decades ahead.

An increasing number of us researchers are working on research and development of battery technology, according to foreign media reports, following the rise of electric vehicles and demand for energy storage solutions at renewables industry.Last week, Sun Microsystems co-founder Bill Joy and his support company Ionic Materials unveiled a solid-state alkaline battery design.They are said to be cheaper and safer than lithium-ion batteries.

Research and development status of solid alkaline battery

"People don't realize that solid-state alkaline batteries can be recharged, but I think people don't seem to be expecting that," Joy said in a telephone interview last week.

According to the researchers, the new alkaline battery technology could be used in three areas: consumer electronics, electric vehicles and energy storage devices for wind turbines.

However, Joy revealed that the company only has the corresponding materials, but does not have the relevant technology, to achieve the commercial operation of the battery.Alkaline rechargeable battery technology could be commercially available within the next five years, Joy told bloomberg.He added: "Ionic Materials has not yet built a factory and is unable to apply the technology to battery production."

The prototype design shows the alkaline battery can be recharged 400 times, and Ionic Materials believes it could be recharged three times in the future.Unfortunately, Ionic's first alkaline battery weighs more than the lithium-ion batteries currently in use, with the exception of commercial uncertainty.

Joy told the New York times that Ionic Materials has made significant progress in developing alkaline battery designs that use cheaper aluminum instead of zinc.The aluminum alkaline battery design may make it lighter than lithium-ion batteries and lower the price of its products.

Lithium ion battery price trend

The price of lithium-ion batteries, meanwhile, is set to fall sharply over the next few years, falling to $273 a kilowatt-hour from $1,000 last year, according to bloomberg new energy finance (BNEF).

Lithium ion batteries have been expected to be in high demand.Sales of electric cars are expected to accelerate to 54 per cent of new car sales by 2040, driven in large part by plummeting battery prices.

The introduction of electric vehicles and the need for energy storage devices will enable lithium-ion batteries and solid-state alkaline rechargeable batteries to compete in the years and decades ahead.The key question is whether alkaline battery technology can be transferred from laboratory testing to product stage for use by a large number of market users.
