Most electric cars at home and abroad, such as Tesla, use batteries made by Korea. Korea occupies the world's number one electric vehicle battery market, and China and Europe are catching up with this position at a terrifying pace.

This is Kim Hye-min.

<Reporter> The

most sensitive consideration for electric vehicle drivers is how long they can drive on a single charge.

[Lee Seung-gi/Electric car driver: You have to charge frequently, and the 450km distance itself gets lower than that when the weather gets cold or when you turn on the air conditioner or heater... .] What

determines this is the performance of the'battery', which is a key component that accounts for 40-50% of the value of an electric vehicle.

This year, the market share of the three domestic electric vehicle batteries was 34.5%, the world's No. 1, more than doubled compared to the same period last year.

LG Chem overtook Japan's Panasonic and China's CATL to climb to the top.

Domestic batteries are being supplied to almost all electric vehicles at home and abroad, including Tesla, Volkswagen, BMW, and Hyundai.

It is an evaluation that 20 years of investment, such as the development of high-density batteries, has yielded results.

However, the pursuit of foreign companies is also threatening.

China's CATL is pursuing with a'low price strategy' with full support from the government, and European automakers have also entered into aggressive investments.

There is also a prospect that Tesla, the world's number one electric vehicle, will start producing its own batteries.

This is why concerns are raised that the'chicken game' aspect may be replayed due to excessive bleeding competition in the battery market called'second semiconductor'.

[Professor Kyung-min Jung/Department of Energy and Chemical Engineering, Ulsan Institute of Science and Technology: I know that the difference between Korean battery-related manpower and China's battery-related emissions is about 1/10th. I think that it needs to be supplemented.]

It is necessary to maximize competitiveness with future mobility manufacturing ecosystems such as electric vehicles, batteries, and semiconductors through collaboration between Korean companies.
