Free QuoteHowever, the restricted temperature range of -25 °C to 60 °C is a problem for a number of applications that require high energy rechargeable batteries that operate at a high temperature (>100 °C). This review discusses the work that has been done on the side of electrodes and electrolytes for use in high temperature Li-ion batteries.
CMB's high temperature lithium batteries have a charge temperature range of -20°C to 60°C and a discharge temperature range of -40°C to 85°C. Our high temperature lithium batteries can operate at 85 °C for 1,000 hours, while other typical lithium batteries would die or fail to work at that temperature.
High-temperature batteries are rechargeable batteries designed to withstand extreme temperatures. They are typically made of Li-ion or Ni-MH cells capable of delivering high levels of power and energy density. Generally, high temperature batteries can be divided into five levels: 100°C, 125°C, 150°C, 175°C, and 200°C and above.
“Also, batteries warm up just from having a current run through during operation. If the batteries cannot tolerate this warmup at high temperature, their performance will quickly degrade.” In tests, the proof-of-concept batteries retained 87.5% and 115.9% of their energy capacity at -40 and 50 C (-40 and 122 F), respectively.
Our high temperature lithium batteries can operate at 85 °C for 1,000 hours, while other typical lithium batteries would die or fail to work at that temperature. Even when CMB's high temperature lithium batteries are operated at 85°C for 1,500 hours, they can still hold a 95% charge capacity.
