Vertical Integration
Technology
Back in 2008, Microvast established our primary R&D objectives to innovate: 'ultra-fast charging', 'long life', and 'non-flammable' technologies for Li-ion battery for automobile applications. With years of intensive research and development, those goals are not just on paper any more.
Non-FlammableBattery Technology
The industry in general believes that lithium-ion battery has certain risks of random short-circuiting and thermal runaway during its production and use, which can cause accidents. Microvast’s non-flammable battery technology takes both active and passive protection measures to protect the battery from short circuiting, resolving battery safety issues through a multi-level approach from materials to the system level.
Non-Flammable Electrolyte
Research has shown that when thermal runaway occurs in a lithium-ion battery, most of its heat is released by electrolytes, which means electrolytes are the key point to ensure safety. Thanks to tremendous effort over eight years by our research team, Microvast has developed an electrolyte that is non-flammable and can be fully charged within 10-15 minutes, with a long cycle life of over 10,000 times.

  • Long cycle life
Temperature Tolerance Separator
A high-performance separator is also an important protection measure for lithium-ion batteries. The newly developed separator uses ‘KEVLAR’ as its basic material, which has excellent performance of insulation and heat stability. Moreover, it has a higher melting point compared to commercial ones, which ensures that it does not shrink even at temperatures of up to 300°C. This has reduced the possibility of thermal runaway and short circuiting.

STL——Smart Thermal Liquid

In addition to improvements of the electrolyte and separator, from the aspect of battery system protection, our Smart Thermal Liquid (STL) technology has a built-in passive protection system to ensure a non-flammable battery.


This cutting edge technology can be applied in different kinds of electrochemical systems, which significantly improves the safety level of lithium-ion batteries.

Microvast LpTO™ (Gen I) technology is built upon lithium titanate (LTO) chemistry, which is known for its outstanding electrochemical and safety performance, unmatched abuse tolerance, excellent capacity retention at extreme temperatures, while being considered the safest chemistry in the lithium-ion family.


Prior to Microvast technology, off-gassing of LTO batteries limited battery life to only a few hundred cycles. Since there is no volumetric change after lithium insertion, “zero strain” results in our batteries having an extremely long cycle life.


With years of intensive research, Microvast has successfully resolved the gassing issue. Microvast launched LpTO technology in 2009 and delivered it into commercial operation starting in 2011. Field performance data shows that after five years of heavy operation in full electric drive urban transit buses, LpTO batteries maintain substantially all of their initial energy capacity.

In 2013, Microvast introduced LpCO technology, which uses modified amorphous carbon material that has higher energy density than LpTO, allowing us to produce fast-charge batteries at a reduced cost. LpCO cells can be fully charged within 15 minutes, and retain 80% of their capacity after more than 10,000 full charging cycles.
Smart Thermal Liquid
  • Liquid Immersion
    Our proprietary Smart Thermal Liquid (STL) technology effectively enhances battery safety by immersing the battery modules in non-conductive liquid. This minimizes any contact the battery cells may have with external moisture and impedes the spread of fire from any accident, while enhancing temperature balance and, in turn, extending power system life.
  • Better Performance
    STL technology enhances battery performance and extends battery life by maintaining consistent battery temperature through pumped circulation or static liquid immersion, depending on application cooling requirements.
  • Safe
    STL absorbs heat and distributes it quickly through the pack, avoiding high-heat transfer to adjacent cells, mitigating thermal chain reactions. Outbound circulation allows sensors to detect abnormal battery conditions, such as electrolyte leakage, facilitating repairs before problems escalate.
