Expanding the Promise of Lithium-ion Technology

TWS's focus is on Lithium-ion cells, today's fastest-growing market sector and the one with most promise for the future.

Lithium has the greatest electrochemical potential of any metal and provides the most specific energy per unit of weight. Though lithium batteries were pioneered as early as 1912, the first commercialized Lithium-ion battery appeared in 1991. The advantages of this chemistry, which include lower cost, higher specific energy and the absence of toxic material, are making it the universally accepted battery for portable applications, gaining momentum in the consumer market and now increasingly in heavy industry also, even including electric powertrains for vehicles.

Lithium-ion is a low-maintenance battery, which has no memory effect and does not need exercising (deliberate full discharge) to keep it in shape and maintain optimum performance. Its self-discharge rate is less than half that of nickel-based chemistries, making Lithium-ion well suited for fuel gauge applications which have become a common feature on electronic devices. The nominal cell voltage from 3.60V to 3.80V can directly power mobile phones and digital equipment, offering simplifications and cost reductions over multi-cell designs.

TWS offers multiple chemical technologies for its Lithium-ion cells – LiCoO2, LiNi(x)Mn(y)Co(1-x-y)O2, LiNixCo(1-x-y)Al(y)O2, LiFePO4 and Li4Ti5O12 – and provides a wide range of different sizes for various applications.
