Japan's old lithium battery manufacturer Toshiba is speeding up its power battery business.
Foreign media reported that Kerala Electrical & Allied Engineering Co. Limited (Kela) is discussing with Toshiba to manufacture fast-charging lithium-ion batteries for electric vehicles. Both parties hope to establish a battery assembly plant in KEL.
“We are passionate about working with Toshiba to assemble lithium-ion batteries of different capacities for various types of electric vehicles, boats, etc. We have already demonstrated our facilities to the team and also showed the team the vacancy suitable for building battery assembly units. Land. "Kel's medical doctor ShajiVarghese said.
At present, India is accelerating the electrification strategy of its two-wheelers, tricycles and automobiles. However, because India has not yet been able to independently produce lithium-ion batteries, it has attracted a large number of Chinese, Japanese, Korean and European and American lithium battery companies to invest in India.
Compared with Matsushita, Samsung SDI, LG Chem and other top Japanese lithium battery companies, Toshiba's power battery can not be compared in terms of market share or capacity scale, but its core fast charge technology has been continuously concerned by the industry. The cooperation between Toshiba and KEL is the fast-charge lithium battery for electric vehicles.
As we all know, fast charge is Toshiba's housekeeping skills. The company introduced Supercharged Ion Battery (SCiB) in 2008, using lithium titanate as the negative electrode for fast charge and discharge, with a lifetime of up to 15,000 times, and can be used in an environment of minus 30 °C.
Mitsubishi Motors' i-MiEV and Suzuki's EVs all use Toshiba's lithium-ion batteries, and Toshiba has established a battery joint venture with Suzuki and DENSO in India in 2017, and plans to invest 20 billion yen to set up factories in India.
However, at that time, the new energy vehicle market had not yet started to develop, and the market demand was not large, which caused Toshiba's fast charging technology to not be widely developed and applied. However, the continued development of the new energy vehicle market and power battery technology remains to be broken but provides Toshiba with new development opportunities.
In 2018, the Toshiba R&D Center developed a high-density TiNb2O7 (HD-TNO) composite electrode consisting of tiny TNO spherical secondary particles with a carbon coating on the surface. The negative electrode material is said to be more than twice as good as the LTO composite negative electrode.
At the same time, Toshiba announced that it has entered into a joint research and development contract with Shuangri and Brazilian mining companies to jointly develop a negative electrode material for lithium-ion batteries using niobium-titanium oxide (NTO), aiming to develop a lithium-ion battery with a capacity that can be increased by 50% compared with the current one.
On this basis, Toshiba announced the development of a new lithium-ion battery that can be quickly charged and long-lasting. When the battery is used in a small electric vehicle (EV), it can travel 320 kilometers in 6 minutes of charging, which is about 3 times that of the past. In the cycle, even if the battery is repeatedly charged and discharged 5,000 times, the battery capacity can be maintained at 90% or more. In addition, fast charging can be achieved in a low temperature environment of minus 10 °C.
It is understood that the new battery uses the rare metal "铌" oxide as one of the negative materials of the battery, Toshiba strives to achieve mass production in the first half of 2020.
Obviously, the current lithium battery companies are developing high-energy density and fast-charge batteries. The main path is to use high-nickel ternary with silicon-carbon negative electrode. At present, enterprises have realized mass production and loading. Toshiba is using a new titanium-niobium oxide anode material, which is technically different from other battery companies, thus ensuring its competitive advantage in the field of fast-charge lithium batteries.
At present, due to the rapid growth of the new energy vehicle market and the breakthrough of power battery fast charging technology, Toshiba is expanding its production capacity through capital investment and alliance to further consolidate and enhance the competitiveness of its fast-charge SCiB lithium battery.
In June 2018, Toshiba announced plans to invest nearly 5 billion yen to increase its lithium-ion battery capacity by 50%. The lithium battery capacity at its Kashiwazaki plant will increase from 1 million batteries per month to 1.5 million units per month. In October, Toshiba announced that it will establish a new plant in Yokohama, which will also be used as a technology research and development center, and is committed to promoting the production of super-charged ion batteries in Toshiba's Japanese and overseas plants.
In addition, at the end of last year, Toshiba announced the spin-off of the SCiB rechargeable battery business into an independent business unit within the company. This indicates that Toshiba has high hopes for the power battery business and provides more resources for it. Pull back a game.
