Hitachi Solid-state Batteries Deliver The Samples By 2020

- Aug 22, 2017-

Researchers at Hitachi in Japan have announced that their solid-state battery technology has been developed and that a new generation of batteries can withstand extreme temperatures in outer space.

Takashi Tanisho, President of Hitachi gashi, says the company can now offer solid-state batteries with the same properties as current lithium-ion batteries, but can handle temperature changes better and have a longer cycle life.

In fact, researchers around the world are on their way to commercializing solid-state batteries.Solid-state lithium batteries have high security, the solid electrolyte nonflammable, non-corrosive, non-volatile, no leakage, but also overcome the phenomenon of lithium dendrite and carry all solid state lithium battery car spontaneous combustion probability will be greatly reduced.

The current energy density of all solid-state lithium batteries is about 400Wh/Kg, and the maximum potential value is 900Wh/Kg.But the solid electrolyte with high resistance, in terms of power density also exists some problems to be solved, the solid electrolyte, anode materials are need to begin, once can effectively solve these problems, will bring about a revolution of new batteries in the future.

In the study of solid-state batteries, Hitachi went ahead.Tanisho said it has sent samples of solid-state batteries to potential customers in the aerospace and automotive industries.In addition, Hitachi is working with an undisclosed Japan battery manufacturers cooperation, improve some detail problems, and solid-state batteries on the market before 2020, and may not be sold under the brand of Hitachi.

For Honda and Toyota, which research solid-state batteries, Tanisho says Hitachi will try to cut costs and maintain a quality lead.Hitachi is focusing on acquisitions in the coming years and aims to become a major supplier of environment-related businesses.

In fact, Hitachi has been a leader in cutting-edge technology, and Hitachi has developed a pure electric vehicle (EV) with a range of about 400 kilometers (EV) using lithium-ion battery technology.The positive electrode material is mainly composed of nickel which is easy to store lithium ions, and the thickness of the electrode is increased to twice that of the original electrode and the lithium ion can be stored.Instead of using the usual carbon materials, the cathode is mainly composed of silicon that is easy to store and release lithium ions.Through these improvements, more lithium ions can be stored.

Comments: many industry insiders believe that pure electric vehicle technology has fallen behind in Japan due to the development route.But in fact, as the first Japanese company to industrialise lithium batteries, even if the global share of lithium is declining, there is still no competition in the high-end market.From Toyota's 2022 production of solid-state batteries and GS Yuasa2020, you can see it.Japan remains a giant in the future of new energy markets.
