Alkaline solid state battery and lithium ion battery which is better

According to foreign media reports, with the rise of electric vehicles and the demand for energy storage equipment solutions in the renewable energy industry, a large number of technicians are working on the development of battery technology. Last week, SunMicrosystems co-founder BillJoy and its supporting IonicMaterials released a solid-state alkaline battery design. It is said that this type of battery is cheaper and more secure than a lithium ion battery.

Who is the mainstream in the future of electric vehicles? Alkaline solid state battery VS lithium ion battery

Development status of solid alkaline batteries

Joy told Reuters in a telephone interview last week: "People don't realize that solid-state alkaline batteries are also rechargeable, but I think people seem to have no expectations for this."

According to research and development personnel, the new alkaline battery technology may be applied to the following three application areas: energy storage devices for consumer electronics, electric vehicles and wind energy generators.

However, according to Joy, the company only has the corresponding materials, but it does not have the relevant technology to realize the commercial operation of such batteries. Joy told Bloomberg that alkaline rechargeable battery technology will be commercially available in the next five years. He added: "IonicMaterials has not yet built a factory and cannot apply this technology to battery production."

The prototype is designed to be recharged 400 times. IonicMaterials believes that the number of times it can be recharged in the future can be tripled. Unfortunately, in addition to uncertain business prospects, Ionic's first alkaline battery weighs more than the current lithium-ion battery.

Joy told the New York Times that IonicMaterials has made great strides in developing alkaline battery designs, using cheaper aluminum instead of zinc. The aluminum alkaline battery design will make it less than a lithium-ion battery while reducing the price of its products.

Lithium-ion battery price trend

At the same time, the price of lithium-ion batteries will fall sharply in the next few years. It is reported that the price of lithium-ion battery packs has dropped from $1,000/kWh last year to $273/kWh.

According to earlier estimates, the demand for lithium-ion batteries is very large. According to BNEF, as of 2040, electric vehicle sales will accelerate, accounting for 54% of new car sales. One of the major drivers is the sharp drop in battery prices.

The promotion of electric vehicles and the demand for energy storage devices will enable lithium-ion batteries and solid-state alkaline rechargeable batteries to compete in the next few years and even decades. The key question is whether the alkaline battery technology can be transformed from laboratory testing to product phase for use by a wide range of market users.
