Koichi Mizushima (scientist)

Koichi Mizushima (scientist) is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Koichi Mizushima (scientist) rather than just read about it. In short: Koichi Mizushima (水島公一, Mizushima Kōichi; born January 30, 1941) is a Japanese researcher known for discovering lithium cobalt oxide (LiCoO2) and related materials for the lithium-ion battery (Li-ion battery). He was affiliated with the University of Tokyo before he went on to work for Toshiba.

Key takeaways

Koichi Mizushima (scientist) belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Koichi Mizushima (scientist) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Koichi Mizushima (scientist) from memory before moving on to harder problems.

Reference excerpt

Koichi Mizushima (水島公一, Mizushima Kōichi; born January 30, 1941) is a Japanese researcher known for discovering lithium cobalt oxide (LiCoO2) and related materials for the lithium-ion battery (Li-ion battery). He was affiliated with the University of Tokyo before he went on to work for Toshiba.

Early career

Koichi Mizushima was trained as a physicist at the University of Tokyo and received a PhD in Physics from the University of Tokyo. He worked for 13 years in the Physics Department at the University of Tokyo. In 1977, he was invited by Professor John Goodenough in the Inorganic Chemistry Department at Oxford University to join them as a research scientist. During his stay (1977-1979) at Oxford, Dr. Mizushima, along with John B. Goodenough, discovered LiCoO2 and related compounds now used for the cathode of the Li-ion battery. He went on to work for Toshiba.

Worked examples

Example 1 — a first encounter with Koichi Mizushima (scientist)

Start with the simplest possible case. Write down what Koichi Mizushima (scientist) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Koichi Mizushima (scientist) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Koichi Mizushima (scientist) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Koichi Mizushima (scientist)

In research: Koichi Mizushima (scientist) appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Koichi Mizushima (scientist) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Koichi Mizushima (scientist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1941 births, Japanese chemists, Living people, so understanding it makes those chapters shorter.
In everyday life: Look for Koichi Mizushima (scientist) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
