End of the second lithium battery! Solid-state batteries really come: smaller and longer battery life

At present, the consumer electronics industry, the battery is the biggest short board, in today's new technology by leaps and bounds, the battery technology still stays in the old lithium battery, which makes mobile phone manufacturers very depressed, in the end when we can usher in the real development of battery technology?

According to CNET, Colorado State Solid-State Power has begun commercial solid-state battery technology, and the first partner is BMW, which promises to provide some form of battery components for each of its products in the next decade, including pure electric Automobiles, hybrid cars and light-duty vehicles.

Compared to lithium batteries, the biggest benefit of solid-state batteries is that they are safer, and the charging speed is faster. At the same density of two batteries, the battery life of solid-state batteries is at least twice that of the former. This is definitely a good thing for automakers. Because the battery size can be halved under the same range of mileage requirements, or the mileage of the vehicle can be doubled without changing the size of the battery pack, while improving performance.

As for the ultra-fast charging function of solid-state battery technology, as the technology advances further, users only need 5-10 minutes to fully charge the electric vehicle. This cost is not high, and it is said that the price of lithium-ion battery will be reduced to 7 years. At $70 per kWh, solid-state batteries will be 20% cheaper than lithium-ion batteries.

In fact, solid-state batteries use ceramic materials instead of liquid electrolytes in general batteries. Another major advantage brought by this change is that it completely solved the hidden dangers of safety accidents caused by flammable liquids and gasoline in lithium-ion batteries.

Of course, the most enjoyable thing is that solid-state battery technology can also be used on mobile devices. Smartphones are also beneficiaries, depending on who uses them first.
